Lesson Plan Outline for Rainbow Science
Young scientists study light reflection and refraction as they determine the critical angle, the rainbow angle, and color separation in rainbows. Teams record the data they collect in a shared spreadsheet and discuss results with the class.
Curated OER
Reflection and Refraction
Life is only a reflection of what we allow ourselves to see. The lesson includes three experiments on light reflection, light refraction, projection, lenses, and optical systems. Each experiment builds off the ones before and...

Measuring The Earth
High schoolers use their geometry and trigonometry skills to determine the distance between their school and another school.
Curated OER
Hit and Run
Pupils explore data collection in this instructional activity. They investigate distance vs. time and velocity vs. time graphs using information collected with a CBR 2 to simulate the reconstruction of an accident.

Building Bridges
Learners identify the different types of bridges. Using the internet, they research information on how they are built by completing a scavenger hunt. Locating a specific area, they determine which type of bridge would be appropriate and...
Curated OER
Tennis Triangle
Learners calculate the height of a tree or flagpole. They measure the shadow of the tree or flagpole and the length of a shadow of a meterstick. Using similar triangles, calculate the heigh. Devise two additional ways in which to measure...

Sled Kites and Trigonometry
Students study the history of kites and their fundamental properties. In this kites lesson students divide into teams and build and fly kites.
Curated OER
Measurement via Triangulation
Students utilize triangulation techniques to determine altitudes of objects. An altitude locator is constructed and used to determine the height of a building or a tree. Tangent tables and formulas provide the ratio for the formula to...
