Science Experiments, 100 Nights and A Bit of Fun!

Congratulations to 22r who has completed her 100 nights of at home reading. Good for you! I am so proud of you!






We have started a science unit on air and water. We have learned that the air is pressing down on earth (air pressure) and that hot air rises. We did two experiments that demonstrate these concepts in a simple manner. The air pressure experiment stays set up in the classroom for awhile so we can see changes in air pressure. The first picture is of our home made barometer. This shows air pressure changes in a simple way. Air presses down on the straw and the straw goes up and down.

 In this experiment we placed a balloon over a bottle. We put the bottle in a bowl of very hot water. We watched the balloon slowly rise up-hot air rises!
