Building a Wind Tube

Wind Tube For our Family Inventors’ Lab class (a STEM class for preschool and kindergarten age), we have built a fun tool, which encourages the kids to tinker – see my last post for how kids play with a wind tube. This post is about the tinkering process we used to build and refine our DIY wind tube.

Supplies

We started with the directions from Exploratorium. We ordered from Amazon:
    • a big, powerful fan – we use the Honeywell HF-910 Turbo Force. (My colleagues tried using a smaller Honeywell, and smaller hoops to save money, and their version can just barely lift a scarf up and out of the tube. It’s just not nearly as fun.) The HF-910 is no longer available but the Air Monster and the Comfort Zone Powrcurve look like they’d work. You need a big fan that can be tilted so it’s horizontal to the floor.
    • TWO 14″ embroidery/quilting hoops and
    • an acetate sheet  Ours is 40″ tall. It comes in a 12 foot roll, you’ll only need about 4 feet of it. Exploratorium’s directions called for .0075 ml thickness, we used .01. It’s a little pricier but it’s been very durable which is important to us because we transport it to several sites and has survived ten years of small children banging on it. (Other builders have used 1/32″ thick polycarbonate, but I haven’t found that in large sheets.)
    • spacers – see below

Assembly

We cut the acetate sheet, rolled it to make a tube, and assembled the tube with the hoops. Definitely a two person job. You can clamp the plastic between the inner and outer layer of the hoop, just like you would fabric. We then used clear packing tape to tape the seam. (We also taped over the metal clamps on the hoops, and the edges of the acetate sheet on one end, just so kids wouldn’t scrape themselves while playing.)

Spacers

You need spacers to lift the tube up off the fan. Exploratorium recommends wooden spacers that you cut a notch in. We built spacers with Duplos and set the tube on those. (You can see them in the videos in this post.) For our family, that worked fine, because it was easy to rebuild them if they got knocked off. For class, I wanted something I didn’t have to rebuild. I found some giant clothespins, which worked great. (You can find 6″ or 9″ options. Nine is better.)
For kids over age 5 or so, that’s all you need. You just set the tube on top of the fan, and you’re fine. They may knock it off a couple times, but quickly learn to be more careful. If it does get knocked off and lands on someone’s head, it’s startling but does not hurt.

Tie the Tube Down?

For kids under 5, you’ll want to tie the tube to the fan so it doesn’t get knocked off as much. Exploratorium recommended drilling holes in the spacers, disassembling the fan, and fastening the spacers on with zip ties. We decided it would be much easier to just thread pipe cleaners through the springs on the clothes pins, and loop those down under the fan and back up again (no dis-assembly required) and twist together to tighten. It was easy to do, worked great to tie them down, and is easy to undo later if desired. An advantage to the clothes pins is that it’s easy to clamp the tube onto the fan, then easy to un-clamp it for transport. ClipMeshTie

Cover with Mesh?

If you will be using the tube with young children, be aware that they may try to put small items into the fan openings (beans, coins, toys, etc.) I usually avoid this issue by putting the wind tube in a hallway or in a large motor play area where there just aren’t any small items to put in. But, if you’re in a classroom full of small smare parts, you may want to cover the fan so they can’t drop things into it. I bought 1.5 yards of black tulle with pretty sparkles (like this), and we wrapped it over the fan, tying it off below with a twisted pipe cleaner. The tulle does work great as safety proofing and looks fine, but it definitely does diffuse the air flow from the fan, so some of the heavier things that would fly without the mesh on just don’t fly well with the mesh on.

Play Value

I’ve watched countless children age 1 – 10 play with this for hours. The under-one-year olds love just watching things fly up and out of the tube. The two-year-olds love shoving things into the tube and watching them fly. The three-year-olds start to make observations on which items flew best. The four-and-ups experiment with building things, tying things together, trying to put things in from the top, and so on. Some of the parents get caught into the experimenting too, folding paper helicopters and such to test what will fly. The kids play really well together – part of the point of this game is to put something in and LET GO, so there aren’t many issues with having to share something that someone was holding on tight to. They all play happily side by side. They don’t really need to take turns, as it works fine to have four or five things flying at the same time. Here’s some of the items we have launched: scarves, ribbons, pipe cleaners twisted into spirals, dixie cups, plastic dishes, and paper cut into a variety of shapes. (See more video in my Wind Tube post.) I have also flown silk leaves for a fall theme, felt snowflakes in the winter. Toy parachutes are also great – if there’s ANY chance the plastic paratrooper will get caught in the fan, just cut him off and use the parachute alone. objects

Alternatives to our DIY wind tube

There is a DIY wind tube tutorial on Instructables. It requires that you own real tools, which I don’t. 🙂 babbledabbledo describes building a simple “vortex” by just rolling a tube of poster board and setting it directly on the fan. Kids put a scarf or a balloon above the tube where it gets caught up in the rush of air. Super simple! I like that with our tube, the kids can put the item in at the bottom and see it travel up the tube, but this simple alternative may meet your needs just as well Kodo Kids makes a wind tunnel that looks fabulous! And I know their materials are very high quality. I’d love to have it, but it costs $499 plus a $50 fan, versus the materials for my DIY tube are around $176 before tax. [Fan ~$55; hoops $20; acetate sheet $82; clothespins $19; optional tulle fabric.] Or you can buy the science museum version for $13,500.

The Wind Tube

We’ve built a fun science exploration tool, which we use in our Family Inventors’ Lab class.

The Exploratorium shared a project idea for building a Wind Tube. (Also check out the Kodo wind tunnel.) It’s basically a clear tube mounted over a fan. Kids can place items into the tube and see what happens. Heavy items just sit there. Lightweight items shoot out the top of the tube. Other items may float, spin, or rattle back and forth. The video at the the top of this post shows some of our initial experiments. (If you want to learn how to make a DIY wind tube, check out my next post.)

Dave Stroud says this about how kids (and adults!) play with a wind tube.

The Wind Tubes intrinsically encourage a particular type of play that helps guests experience the way science works. The intent is for guests to internalize a science based mindset – do something, measure the outcome, make changes, do something, measure the outcome, compare the outcomes, make changes, do something, measure the outcome, compare the outcomes – repeat this process until you run out of time. The user experiences the phenomena by exploring it, rather than being shown an outcome and having it explained. (Source)

I have definitely seen this in action. Toddlers and preschoolers love to launch the same items over and over. Four to five year olds start experimenting more, looking around the room and deciding what to try next! As they experiment, I hear them talking: “I wonder what this will do?” “What can I try next?” “What do you think will happen this time?” “That didn’t work, I wonder if I could combine it with this?” It’s “tinkering” at its finest! Older kids, teens, and adults enjoy engineering items to achieve different goals – lifting up heavy materials, designing a neutral buoyancy item that will float in the tube forever, or creating items that spin on their way up.

As Stroud says, this activity results in:

• Making guests [child] less reliant on “authority” to answer questions
• A higher level of engagement and deeper investigation
• Guests defining their own success and making their own meaning (user defined outcomes)
• Generating a particular category of questions such as: How can I get it to…? What if I…? Instead of: Why does it…? What makes it…?

Here are some of the experiments my family developed just in a few hours of play when we first built our tube:

Scarves. An easy peasy thing is scarves – they catch the wind so nicely, then gently flutter to the ground.

The Frisbee. (really a plastic lid)  It gets caught in the air currents and will float forever. My son learned that if you put your arm over the fan to block some of the air flow, the Frisbee will sink down the tube.

Cardboard boat. This cardboard snack tray will float easily on its own. The small plastic monster will not – it’s too heavy and not aerodynamic. But, put the monster in the boat and it floats!

Parachutes. This plastic pterodactyl won’t fly even though it has wings. But, if you build it a parachute out of a plastic bag and a pipe cleaner, it soars. Note: you can also make parachutes with coffee filters or use these parachute party favors. (Amazon affiliate link)

Pipe cleaner spinner. My personal favorite is this twirled-up pipe cleaner that spins and spins as it floats in the air.

Tops. And speaking of spinning, watch these plastic tops. They don’t float, but they definitely respond to the wind!

Other materials to try: scarves, balloons, rubber gloves blown up and tied, dixie cups with coffee filter parachutes, whiffle balls, strawberry baskets, etc. I also really like these three projects… these pictures were from the wind tube activity at the Orlando Science museum.

Here is a printable template for the helicopter shown above.

Here are ideas from the Cincinnati Museum of Natural History:

As kids play, they learn hands-on about aerodynamics, wind currents, how lightweight things fly better than heavy things, but even heavy things can fly if they have a parachute or an “air ship” that can catch the wind currents. Having the ability to play hands-on with this will allow them to internalize the learning much more than when they cover all this stuff in high school physics class someday!

Challenges for Kids:

For older kids, you could make a poster to accompany this activity with challenges like these from MOTAT:

  • Can you build something that will leave the tunnel in a particular direction?
  • Can you build something that will hover above the wind tunnel?
  • Can you make something that spins clockwise as it rises in the tunnel?

Fun with Toddlers: Pet Theme

This month’s theme was Pets, especially dogs and cats. Here are some fun pet-related things to do with your toddler:

Outings to Go On: Visit a pet store. Look at the fish, or the rodents, or the birds or reptiles. The pet store is just as educational as the zoo, and it’s free! It’s a great chance to talk to your child about animals, and to practice observation skills: “Can you find a yellow fish?” “Which is the biggest bird?” “These are all reptiles. What makes them different from the rodents we just looked at?” If you don’t have a pet at home, don’t feel like you have to buy anything. Most pet stores are used to parents coming in and hanging out with their children for a while. If you want, you could buy a bag of pet food to donate to the store’s pet food drive. (Look for a donation bin at the front of the store.)

Toys to make for your child

Balloon Puppies. Take a balloon. Blow it up. Draw animal features on, add a string and you have an instant pet for your child to take on a walk! If you want to be fancy, you could use a helium balloon and fasten on “legs” made of accordion-folder paper – the home made version of the toy pictured.

petsDoggy ears (or kitty ears). Make a circle of paper that fits around your child’s head and add ears, or turn a child’s headband into the base for ears.

Imagination Games to Play

The Dog House. Take a big cardboard box. Cut an arched doorway in it. Decorate it like a dog house. Add things to represent dog food dishes, dog bones, dog toys and more. Add stuffed puppies if you have them, and then let the play begin.

Pet Store. Set up a pet store with stuffed animals, and accessories for animals (food bowls, collars, treats, toys, and so on, and go shopping.

Songs to Sing / Rhymes to Say

Where has my little dog gone?
Oh where, oh where has my little dog gone?
Oh where, oh where can he be?
With his ears cut short and his tail cut long,
Oh where, oh where can he be?

How Much is that Doggie in the Window
How much is that doggie in the window? The one with the waggly tail?
How much is that doggie in the window? I do hope that doggie’s for sale.
[Search on YouTube for many videos of this song!]

I have a cat
I have a cat (stroke your fist); My cat is fat (arms form a stomach)
I have a cat (stroking); My cat wears a hat (hands on head)
I have a cat (stroking); My cat caught a bat (clap hands together above head)
I have a cat (stroking) Purrrrrr, Meowwww

Circle Time Ideas

Poor Kitty. There is a game that elementary school aged children love called “Poor Kitty”. One person pretends to be the kitty and goes around a circle, trying to make the other kids laugh (by purring rubbing against them, licking them…). The others are supposed to keep a straight face and just pet the “cat” and say “poor kitty” without laughing. You can adapt this for a one-on-one game with toddlers or preschoolers. (Though they probably won’t get the whole “you’re not supposed to laugh” idea.)

Puppy puppet. Bring a puppy puppet and some dog treats (or dog toys.) Give a treat to each child. Bring the puppy around the circle and have each child give the dog a treat. Have fun with pretending to be a happy puppy.

Purple cat, what do you see. Make a felt board collection of pets – brown dog, black cat, yellow bird, gold fish, etc. Give one animal to each child. Do the rhyme, similar in style to Eric Carle’s Brown Bear. Go around the circle to each child in turn, having them place their animal on the felt board. So, if you started with brown dog, and the first child has a black cat, you’d say “Brown Dog, Brown Dog, what do you see? I see a black cat looking at me.”

Books to Read

Roly-Poly Puppies by Elaine Moore. A counting book with a nice rhyming structure.

Pete the Cat by James Dean. There are lots of fun Pete books, but the best is I Love My White Shoes. (Check out our Pinterest page for lots of activities to go with Pete books!)

Aggie and Ben by Lori Ries. Ben’s dad takes him to the pet store to pick out a pet.

Motivation, Punishment and Reward

starsOur kids are always learning from us. They learn by observing as we role model a variety of skills, they learn by interacting with us as we play, and they learn when we actively “teach” them. There are many things we teach casually, and aren’t too worried about the exact timeline when our child picks up the idea. Things like covering your mouth when you sneeze, saying please, or putting their dish in the sink. There are other things though that we may have a sense are REALLY IMPORTANT, or that we believe MUST BE DONE BY A CERTAIN AGE and those are the things we tend to stress about our child learning. Potty training and reading both fit in this category for many parents. What happens when there is something we really want our kids to learn?

The first thing I’d ask you to consider: Is this skill developmentally appropriate? Can we typically expect a child of this age to learn this thing? Once you’ve learned it is appropriate, then you can consider teaching it.

Motivation

There will be many times in your child’s life where you want them to do something they don’t want to do, or there’s a skill you want them to learn because it will be valuable in the long run, but they aren’t particularly interested in learning at this moment in time. How can you help them find their own internal motivation? Potty training is one of our first chances to explore this challenge, so we’ll use it as our example.

First, consider your motivations. Why do you want your child to learn this new skill? Here are some common reasons and some examples from the potty training process.

  • Outside demands: Is it pressure from a pre-school or daycare that requires it by a certain age?
  • Peer pressure: Is it because other families are doing it, and you’re feeling peer pressure to keep up? The media and social media can also create this pressure of what our child “should” do.
  • What you do or don’t want to do yourself: Are you just tired of changing diapers? Or tired of paying for diapers? Or washing them?
  • What you want for your child: You want to encourage your child toward independence in all areas?

The clearer your motivation, and the stronger your motivation, the more time and energy you’re likely to be willing to commit to the process. Some parents actually find that they’re not actually motivated to teach a skill. For example, the diaper routine might be working for their family’s schedule and commitments. This is fine for a while, but at some point (maybe three years old for potty training?) it’s time to help your child move forward.

Then ask yourself: What are your child’s motivations? Try to view things from your child’s perspective and understand why they might not be as interested in learning a new skill as you are in teaching it.

In our potty training example: Why might a child prefer to continue to use diapers? Some ideas: they’re used to eliminating in their diaper – it’s comfortable and familiar. They may be in a state of regressing a bit, and not feeling bold enough to be ‘a big kid’. They may not like interrupting play time with trips to the potty. They might be frightened of the potty. They might be rebellious toddlers, defying their parents ‘just because.’ They might have a desire to be completely in control of their bodies. They might also have been constipated at one point, and found that it hurt to have a bowel movement, and be afraid of repeating that experience.

Then ask: What might motivate your child to use the potty? Some options are punishment or rewards…

Punishment?

It’s best not to use punishment. Punishment can definitely work in the short term, in that a child who is punished for doing something (e.g. eliminating in a diaper) may well try hard to avoid that punishment in the future (e.g. by using the potty). But it could also shame them and damage their self-esteem. And it also means that they’re doing something only to avoid punishment – not for any positive reason.

On the other hand, logical consequences are appropriate, as long as they are done without shaming. For example, having them help with clean-up after an potty-training accident allows them to see the consequences. Or taking back the big kid underwear, saying ‘it looks like you’re not ready for this yet… let’s go back to diapers for a while’, helps them to see what the goal is and what the reward is of accomplishing it.

Rewards

Many people use a sticker chart, or other reward system when they want to shape behavior. The general idea is: talk with your child about what you want them to do, tell them that when they do it they’ll get a reward. Then involve them in setting up the system: pick out the reward, or make the chart, etc. For rewards, it’s best to choose something cheap and easy to obtain, like a sticker. (Not candy.) For a toddler, the reward needs to be immediate for them to understand “when I do this action, I get this reward.” Older kids can work toward a bigger reward over time – “if I do all my chores this week, we’ll watch a movie together on Friday night.”

Make sure they are clear about what the behavior is you are working on, and be consistent about the response. For example: “if you sit on the potty, you get a sticker whether or not you pee there” may be a good first level. Later on, when they’ve mastered that step, you ask more of them: they need to actually pee or poop to get the sticker. You may choose to also have a cumulative goal to work toward, like “once you’ve pooped in the potty 10 times, you will have filled the chart, then you get a new toy.” It’s important to think of these rewards as short-term reinforcement, not an on-going system! Over time you will phase out stickers completely. Rewards can be a very effective tool for toddlers. However, you don’t want to over-use rewards! And you want to make sure the focus is on accomplishing the goal for its own sake, not on just doing something so they get a reward.

Expectations

If you regularly say “If you do this [bad thing], then I will punish you by [negative consequence]”, your child might come to feel that you expect him to do bad things and you look forward to punishing him. Instead, try “When you do this good thing then you get this [positive consequence].” Make sure your tone of voice implies that you have confidence that they will do the good thing because that’s what you expect of them.

Praise

When your child accomplishes something for the first time, definitely praise them. If it’s a HUGE accomplishment, make the praise really big. But honestly, if it’s small accomplishment, the praise can be just a quiet observation that they accomplished it. As they start repeating a skill again and again, on the way to mastery, we can fade out our praise. It feels silly and a little embarrassing to get praised for something you’ve mastered (as you know if your child has told you something like “You peed in the potty! Good job mama!”) Praise them for what they have done, and the work it took to do it.

Read more about praise here.

The Downsides to Rewards & Praise

Critics of rewards say they are a short-term solution to gain compliance with parental requests, not a long-term path to instilling the behaviors, qualities, and values you want your child to attain. And, research has found that kids who are raised on a series of rewards can become more self-centered, materialistic, reward junkies looking for their next fix from parents who can become exhausted by coming up with new rewards.

Research has also shown praise can backfire. If we continually praise our child for being “smart”, “beautiful” or “strong”, then they may be afraid to take risks – not wanting to do anything that they might not succeed at… fearing that then we will realize they’re not so smart or strong or beautiful after all – and thus not lovable. Also, when a child is vigorously praised for every little thing she does, she may not know whether praise is genuine.

Experts recommend that when you want your child to learn a new skill, think about what it is you are really trying to teach and stay focused on that. Work with your child to find their motivation for learning this new skill. As they make attempts along the way, give specific praise for their efforts and their commitment, and specific recommendations for how they might improve. The emphasis is more on the process than the product, more on the work they do than on the “talent” they have. When they accomplish a goal that they set, then it is totally appropriate to celebrate that with something (Stickers? M&M’s? A special toy?) as long as the emphasis is on the value of the accomplishment itself, not on having done whatever they needed to do just to earn the reward.
