Help your class understand the magnitude of the distance between Earth and Mars with an activity that asks small groups to use balloons to create scale models of the Earth, Moon, and Mars. Class members figure out the distances...

Middle and high schoolers perform transformations. In this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.

Playing with mathematics can invoke curiosity and excitement. As pupils construct triangles with given criteria, they determine the necessary requirements to support similarity. After determining the criteria, they practice...

Future environmental scientists compare data from two different conservation strategies. Alone this lesson is sufficient, but as part of the Exploring Biomes unit produced by the Arizona Fish and Game Department, it becomes top-notch. 

Use ratio and proportions to adjust recipe size. Middle schoolers investigate Australian food and adjust the recipe size for said foods according to the given situation. They then prepare Australian foods.

Examine food choices and the nutritional properties of food groups with this visually appealing whole-class lesson plan. This will take a bit of preparation, but once you do it, you can use the materials for years. Using a food groups...
