Where Do We Choose to Live and Why?
Source Institutions
In this geography investigation, learners use a nighttime satellite image to observe areas of light across the United States and to identify patterns and spatial distributions of human settlements.
Comparing Sizes of Microorganisms
Source Institutions
In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
Life Vest Challenge
Source Institutions
In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.
Clipper Creations
Source Institutions
In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.
Reflective Solar Cooker
Source Institutions
In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.
Hand Biometrics Technology
Source Institutions
In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin
Interactive Gumball Machine
Source Institutions
In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.
Aerial Imagery
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.
Light Bulb Challenge
Source Institutions
In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.
Biotech in a Bag
Source Institutions
In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.
Keep Out!
Source Institutions
In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.
Shaking It!
Source Institutions
In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.
Fruity-Glows: Pictures of Health on a Microarray Canvas
Source Institutions
In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.
Blowin' in the Wind
Source Institutions
In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.
Sustainable Grazing
Source Institutions
In this activity, learners investigate the food, water, and space needs of common livestock animals.
Prepare for a Construction Zone Field Trip
Source Institutions
In this activity, learners explore work, forces, simple machines, and construction. This lesson guide includes simple ways to demonstrate these principles as well as hands-on activities.
Infrared Investigations
Source Institutions
In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
Survivors! The People of the Arctic
Source Institutions
In this activity, learners use maps to locate the Arctic region and use a word game to discover the types of resource people need to survive in the extreme climate.
Conveyor Engineering
Source Institutions
In this activity, learners explore the engineering behind the conveyor belt and consider the impact this invention has had on transportation and the coordinated shipping and delivery of goods.
Building an Army
Source Institutions
