Last week, the Top Dogs went to Mr. Delzer's classroom to do a STEM (science, technology, engineering, and math) project with his class. We worked on making Roto Motors, and we counted the number of rotations they each had. We made a prediction, and found out it was impossible to count how many times it spun around, because it moved WAY too fast. We tried bending the wings different ways to see how it affected the motor. We also added a paperclip to the bottom of the roto motor to add some weight to it and see what happened. Mr. Delzer showed us how to count the rotations by adding a long piece of paper to the motor and attaching it to the floor. When we got back to our room, we wrote in our Writer's Notebooks about our experiment so we wouldn't forget all the details! We can't wait to do another project with his class tomorrow! STEM is fun!!!
You will have to look for the white blur in these pictures - the roto motors spun so fast I couldn't get still pictures with my iPhone! :)
