To continue their study of matter, the second graders focused on wind (a gas) and how wind can be used to produce clean energy. They planned, designed, and created wind powered cars. When testing their cars they discovered the needed to make improvements several times in order to get their cars to move efficiently.

Second graders explored states of matter using bubbles during their STEM time for a couple of weeks. First they were presented with a variety of bubble wands. They had to predict if the bubble wands given to them would make large bubbles or a large number of bubbles. Then they went outside to test them and record their results. In the next session, students planned and designed a bubble wand using pipe cleaners that would either create large bubbles or a large number of bubbles. When we went to test them they were amazed that they actually worked!
Students incorporated the engineering and design process to build and measure pencil towers. First they estimated how tall they thought it was and then they used a ruler to find the actual measurement of their towers. Next they worked to improve the heights of their towers and communicated their strategies with the other groups.
