Fine Motor and Science- Absorption Experimentation

absorption experiment
Yesterday we did an experiment exploring absorption. Absorption is when an object absorbs or soaks up a liquid. Yesterday we made it easy. Today we are really testing which objects absorb and which objects do not absorb.

The use of the pipette puts the hand in a pincer grasp and while coaxing the water into the pipette your child is using their fine motor skills. Also the picking up and moving of the cotton balls is using their fine motor skills as well

We used materials from around the house. So everyone will use different things I also split the tray so that objects that absorb are on one side and objects that repel the water are on the other side.

Fine Motor and Science- Absorption

fine motor absorptionSo you may be wondering how fine motor ties into this, well lets look at what the components of this project are so we can find where fine motor comes into play. Below is our initial set up. Pretty simple a bowl of water with some liquid water colors to add some pretty color, a pipette, and a bowl of cotton balls on a tray. The use of the pipette puts the hand in a pincer grasp and while coaxing the water into the pipette your child is using their fine motor skills. Also the picking up and moving of the cotton balls is using their fine motor skills as well.

Absorption is when the cotton ball absorbs or soaks up the liquid. So we started this by asking the kids to make 3 puddles of liquid on their tray.

IMG_20160329_110827284Once the water started leaking from the cotton ball we started the process all over again with another cotton ball and then another.

How to make a Wind Tunnel

Wind Tunnel
When we visited my parents in Washington there was a great Kids Museum we visited that had a wind tunnel. Mikey and Kaia probably spent about an hour there playing with it. I didn’t mind I was there playing with it to. Ever since then I have wanted a wind tunnel of our very own. I found one made by Kodokids (that is where the picture above is from).

I am completely obsessed with the kodokids wind tunnel. It is on my wish list. Unfortunately I cannot convince my husband that a wind tunnel is a necessity. So I think the beautiful Kodokids Wind Tunnel will remain a dream. Well when I obsess over something I really obsess. So I think about it often, I try to figure out how I can make something similar with what I have and so I came up with what you see below.


I looked through my house unfortunately I do not have any fans even remotely the same size as the one pictured. I did however find an old hair dryer in my garage so I had a jumping off point. I knew I had to direct the air. If you read my blog you know I have a thing for upcyling plastic bottles. I found a plastic bottle and used a box cutter to cut off the bottom of the bottle.

I placed the bottle over the hair dryer

I then used duct tape to attach the bottle to the hair dryer. I did not want the hot air to melt the bottle or to burn the kids hands so I taped down the cold air button. I now needed something to hold the dryer in place. I wanted it covered so the kids would not play with the on off switch to much. I had a Styrofoam cooler I thought would be perfect so I cut a hole in the top. I used a dowel to hold the hair dryer in place. I placed it all on top of a wire rack that came with my fridge. I wanted to make sure there was plenty of ventilation.

The result was better than I had hoped for. It works great. Mikey figured out we can have two balls going at once. He is able to move the balls without touching them. We will practice with more objects later. I am just so excited that this actually worked. While I am still dreaming of the Kodokids Wind Tunnel . I at least have my make shift wind tunnel to let the kids learn and discover with.

Let me know if you try this out. I would love to hear all about it and see pics too. Any ideas on what we should use to play with on our wind tunnel? Leave a comment I am so excited to see what you all can come up with.

I made another wind tunnel closer to the one saw at the Museum. if you Would Like to see how  I made it check this link
