Quiz: Weather Prediction
In this science worksheet, 3rd graders will focus on the weather. Students will respond to ten fill in the blank questions regarding weather prediction.
Curated OER
Kepler and his Laws
Pupils examine Kepler's Laws. They confirm Kepler's 3rd law by comparing orbital periods and mean distances for all major planets and study conic sections, qualitatively.
