We started an “I Wonder” wall to share our questions about air and water Mrs. Cassell used a program called Padlet to create our “I Wonder” wall. When we got our iPads we had to open an app called Qrafter. Qrafter scans black and white pictures that tell our iPads how to find a website – today the website was our “I Wonder” wall. Mrs. Cassell showed the the black and white picture (called a QR code) on the SMARTboard. Each group got to go up the SMARTBoard can scan the code with their iPads. It was fun and super easy. Then we clicked on the link and it took us right to our “I Wonder” wall. Next we all got to add our own sticky notes to the “I Wonder” wall with our questions about Air and Water.
To help us answer some of our questions about water we video conferenced with the Texas Wildlife Association. We made a list about what we learned:
1. Water is made of H2O (hydrogen and oxygen) – we still don’t quite understand what molecules are but we will be learning more about what H20 means next week.
2. Almost all the water on Earth is salt water from the oceans.
3. Some of the water we drink comes from fresh water above the ground in lakes and rivers.
4. The rest of the water we drink comes from under the ground.
5. The water underground is stored in aquafers; aquafers are like underground caves made of rock where the water is stored
6. Elanor did an experiment where she dumped water on plants and soil in a container with hole in it and a bucket underneath. She also poured water on a rock in a container with holes in it and a bucket underneath. She asked us what we thought would happen to the water. We guessed that the water poured on the rock would not soak through, but the water on the soil would. We were right! We learned that the aquafers fill up when rain water soaks through the soil. If there is a lot of rock the water can’t get underground to fill the aquafers.
7. We talked about the water cycle. We understand that water from the ground evaporates into the sky and then makes clouds. When the clouds get full it rains. We want to spend some more time learning about the water cycle and how clouds are made.
8. When you flush the toilet it uses 25 gallons of water! We saw what a gallon jug looks like. That is a lot of water!
9. Elanor asked us to think about how we could conserve water. Conserving water means to use just what we need without wasting it.
10. We would like to learn more about water conservation.
