Product Description
Scientists make discoveries about our natural world through experimentation, collecting data, and looking for patterns in the data to then come up with a theory to explain the data or a law to describe the data.

This is a mini unit of three lessons where students investigate the relationship between the load and effort at different distances from the fulcrum. They set up the experiment, collect data, analyze data and by the end of lesson 3, they should be able to come up with a law to describe their observations.

A scientific law is a relationship between the observed variables. It is a mathematical relationship.

Knowing this essential to understanding nature of science.

In conducting the investigation themselves, the students not just gain knowledge and understanding of levers, but also develop skills for them to see how the science concept is applied in engineering design of everyday objects.

The unit consists of
3 Lesson plans based on the 5E teaching and learning model
Data collection sheets to record results
Sample result sheets with conclusions
Evaluation sheets for the three lessons, which can be set as homework.
