The Boxes Go MobileAdd to list Details
Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.
In this activity, learners build inexpensive pulley assemblies from pulley wheels used for sliding screen door replacement or from clothesline spreaders.
Why are Compact Fluorescent Bulbs More Efficient?Add to list Details
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.
Manufacturing Technologies: Making a Picture Frame
Learners examine the manufacturing process while they make picture frames from cereal boxes.
How can You Demonstrate the Efficiency of Different Light Bulbs?Add to list Details
In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.
Solar Water Heater
Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.
New Boxes from OldAdd to list Details
Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.
Divide and Conquer
Learners work in groups to build model cars from paper parts. First, each learner builds cars individually and the group times themselves.
In this activity, learners investigate passive solar building design with a focus solely on heating.
