Word of the Day: Vibration!
Today was a very exciting day in science! We have been talking about sounds, and how they are made and travel. Our experiment today revolved around the fact that sounds are vibrations, and they travel in waves. The students created tubes with wax paper on the ends, and then "hummed" into the end, causing the tube and the paper to vibrate (similar to a kazoo). It was really loud in here, but LOTS of fun! I have attached a few samples from their content journals to show their thought process through our experiment!
