Get a direct stretch from a spring. The presentation shows how Hooke's law uses direct variation. Scholars see how to calculate the spring constant for a spring given a stretch distance and a force. Individuals then use the spring constant to find the stretch for a different force and determine whether the distance is reasonable.
- Gather different springs and have the class measure the stretch based on different weights and calculate the spring constant for the springs
- Pupils should be able to solve one-step linear equations
- Assumes learners know how to convert an improper fraction to a mixed number and a decimal equivalence
- Highlights needed information within the problem
- Explains the importance of using the same units throughout the problem
