Efficiency

Many innovators are working on solutions to address environmental problems like energy-inefficient housing. Scholars have an opportunity to develop their own strategies using the fourth of five lessons from the WE Are...

Things should heat up during a hands-on lesson exploring solar energy. An enlightening activity challenges young scientists to design a structure that collects solar energy efficiently. They keep track of temperature data over time and...

Think like an engineer and an agricultural scientist over the course of 12 lessons in a STEM based unit. Young scientists take on the roles of animal physiologists, animal geneticists, agricultural engineers, animal nutritionists, and...

Fourth graders investigate two types of water vessels that were used by Lewis and Clark during the exploration of the Louisiana Territory. They interpret data to determine which vessel was more efficient.

Students study friction and how the ball bearing was improved upon to increase efficiency.  In this friction lesson students work in groups to complete an activity and worksheet.

Students build and compare models of both an energy inefficient and efficient classroom. In this energy efficiency activity, students creatively use recycled materials to build two separate classroom models. They factor in concepts such...

In this energy efficiency learning exercise, students fill in the blanks by explaining why energy efficiency is important, and by listing two ways to conserve energy. They draw a picture of someone using energy efficiently in their home...

Elementary schoolers discover how engineers use solar energy to heat buildings. They take a close look at some of the materials used: sand, salt, water, and shredded paper and evaluate the efficiency of each material. An incredible...
