Experimental Design with Force Lesson


TEKS Science: 6.2A, 6.2B,6.2E, 6.8A CCRS Science Standards: VIII-D1, VIII-D2


Lesson Objectives:


  1. Students will be able to predict and justify results from an experiment. 
  2. Students will be able to observe the pattern that forces of springs are proportional to the distance they stretch or compress.
  3. Students will be able to explore how the potential and kinetic energy of an object changes as it is in motion and in different environments.

Lesson Overview:

Students will complete an experiment that explores how springs behave differently with different objects are attached. A compression spring will be demonstrated by a toy, which launches off the surface of a table. The students will explore extension springs using two supplied objects. The students will use their collected measurements to estimate the mass of another object based on its displacement of a spring. Potential and kinetic energy will be discussed as they relate to the spring used in their experiment. The students will use a PhET simulation to explore how the potential and kinetic energy of a spring changes as an object is in motion. Using the simulation, the students will be able to change the environment their spring is in. They will be able to formulate conclusions about how the environment influences the object’s potential and kinetic energy.
