Construct an explanation that the gravitational force exerted by Earth causes objects to be directed downward, toward the center of the spherical Earth.
The Utah Science with Engineering Education (SEEd) Standards outcome 3.3.3 (Physical Sciences) for Grade 3 says: “Construct an explanation that the gravitational force exerted by Earth causes objects to be directed downward, toward the center of the spherical Earth.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Utah Science with Engineering Education (SEEd) Standards.
Forces at Work: Gravity, Resistance, Levers and Pulleys Grades 4–5
Do heavy things really fall faster? Why are fast swimmers shaped like torpedoes? How can a small push lift a big load? Three hands-on lessons on gravity, air and water resistance, friction, levers and pulleys, measured in newtons with homemade and simple tools.
- Do heavy things really fall faster? 60–70 min
Teams drop a light and a heavy container side by side and find that they land together, then add parachutes of three sizes and time the fall. They calibrate a rubber-band force meter in newtons and explain what gravity and air each do.
