Avalanche!
Students explain that when forces on an object are balanced, the motion of object does not change. They describe how an object changes its motion when forces on it are unbalanced. They plan and conduct a scientific investigation to test...
Curated OER
Good Vibrations
Students demonstrate sound waves and make changes in the waves
resulting in changes in pitch. Students associate changes in pitch in various "musical instruments"with size and shape and the sound waves they produce.
