Background For Teachers:
This lesson plan uses a pendulum, as when a pendulum is set in motion it remains in motion, thus allowing time to perform experiments on an object in motion. Many universities exhibit large pendulums that actually show the rotation of the earth, hence they are important instruments having to do with force and motion.
This activity requires students to practice a basic scientific process. A
question is given to them and they make predictions before setting up an
experiment to prove or disprove their prediction. Students record their
results and analyze their findings.
Intended Learning Outcomes:
Students observe forces in nature.
Compare the effects of a
strong wind and a light breeze on a shrub or tree. Observe cars
going by their house. If they live near an intersection, watch and
compare the force necessary for the car to slow down to turn. Do
cars traveling at higher speeds have to brake sooner and harder
than cars traveling slower? What else did they discover that
changed its motion as a result of being acted on by a force?
Report findings to the class.
King, Kenneth. (2005). Making Sense of Motion. Science Scope. p. 22-26.
“Making Sense of Motion” begins with a general statement that interest in motion comes at an early age as exhibited by a very young child playing with a car and making the vrooomm sounds that suggest speed. All students need to develop an understanding of motion and force. Activities including hands-on investigation involve use of higher order thinking skills.
