Curated OER
Gears 2
In this gears worksheet, students use a ruler and gears to conduct an experiment. Students follow 11 sets of directions,write a conclusion, and graph their results.
Curated OER
Gears 1
In this gears worksheet, students put together and label gears and see how many turns it takes to go in a given directions. Students then fill in a chart with their results.

Science: The Bicycle as a System
Learners explore how the different parts of a bicycle relate to each other and identify the subsystems. They discover how bicycles work and investigate their history. In groups, students research each of the subsystems and present...
Curated OER
Household Tools
Students explore parts of a system. In this simple machines lesson, students discover that simple machines are composed of two or more systems. Students examine household tools and assess the parts of the system.
