Students will use writing to explore the concept of Gravity. This lesson includes a "lab" activity and a writing assignment. In the Lab students will explore how gravity affects pieces of paper dropped to the floor. Assignment includes a data table, graphing assignment and analysis questions. Also included in the lab is an extension activity for advanced students or students who finish early.
Once the paper gravity lab is completed, students will write a fictional story about a day in their life if they woke up and there was MORE or LESS gravity than normal. Includes graphic organizer for students to organize and plan their writing.
Can be adapted for younger or older students depending on ability.
2. Unbalanced forces cause changes in velocity. As a basis for understanding this concept:
a. Students know a force has both direction and magnitude.
b. Students know when an object is subject to two or more forces at once, the result is the cumulative effect of all the forces.
c. Students know when the forces on an object are balanced, the motion of the object does not change.
d. Students know how to identify separately the two or more forces that are acting on a single static object, including gravity, elastic forces due to tension or com pression in matter, and friction.
e. Students know that when the forces on an object are unbalanced, the object will change its velocity (that is, it will speed up, slow down, or change direction).
f. Students know the greater the mass of an object, the more force is needed to achieve the same rate of change in motion.
g. Students know the role of gravity in forming and maintaining the shapes of planets, stars, and the solar system.
