In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.

Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

My Angle on Cooling: Effects of Distance and Inclination
Source Institutions
In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

Double Dutch Distractions
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Double Dutch) is a full inquiry investigation into whether hearing or seeing has a bigger effect on jump rope performance.

The Parachuting Egg
Source Institutions
In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

Patterns and Relationships: The Magic Box
Source Institutions
In this math lesson, learners participate in a variety of activities that give them experience in recognizing, describing, and extending repeating and arithmetic patterns.
Signs of Change: Studying Tree Rings
Source Institutions
In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

Tug-of-War
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Tug O' War) is a full inquiry investigation into tug-of-war physics. Groups of learners will test two tug-of-war strategies.

FlyBy Math: Distance-Rate-Time Problems in Air Traffic Control
Source Institutions
In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.
