We explored gravity and air resistance by designing and making our own parachutes and paper helicopters.
First, we watched Felix Baumgartner’s skydive from Space and discussed what forces we could see in action.
We then designed our own parachutes and landing crafts for an egg. We wanted to see if we could land them safely without cracking the egg. We used a range of materials to create our parachutes. Three out of six of our parachutes were successful!
Here are some of our designs and parachutes:
We also created paper helicopters. We dropped them from the same height repeatedly. We found the average time it took for them to fall. Then, each group adapted their helicopter to see if they could increase the time spent in the air.
Here is what our paper helicopters originally looked like:
In Ms. Ryan’s 1st Class we investigated different materials to see which ones were waterproof. We used Buster the puppet to help us. We predicted if the following materials were waterproof; rubber, cotton, nylon, plastic and tin-foil. We recorded our predictions.
We tested the materials by wrapping a piece of each one around Buster’s arm. Buster’s arm was dipped into the water for thirty seconds each time. We then checked to see if his arm was wet or dry. If his arm was dry it showed us that the material was waterproof. Sadly, poor Buster got wet when we tested the cotton, nylon and tin-foil as these are not waterproof. We would not recommend using these materials when making a raincoat.
In Junior Infants we investigated different materials. We guessed which material would be best for building a house; straw, wood or bricks. We recorded our predictions.
We tested the materials by sqeezing, ripping, pulling them to see if we could break them. The children worked in groups and constructed houses made out of straw, wooden sticks or lego(plastic). We learned about different types of materials (metal, wood, plastic) and sorted them.
