Tinkering with Tops
Source Institutions
In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.
Heavy Lifting
Source Institutions
In this activity, learners work in NASA teams to build balloon-powered rockets using identical parts and compete to launch the greatest number of paper clips to "space" (the ceiling).
Design a Landing Pod!
Source Institutions
In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).
ZOOM Glue
Source Institutions
In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.
Gravity Fountains
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.
Bubble Trouble
Source Institutions
In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.
Making a Battery from a Potato
Source Institutions
In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.
Strengthen a Paper Bridge
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp
Pressing Pressure
Source Institutions
In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.
Capturing Homemade Microgravity
Source Institutions
This activity (page 2 of the PDF under SciGirls Activity: Microgravity) is a full inquiry investigation into how ordinary things behave in microgravity, similar to what astronauts experience.
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.
Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.
Kites
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.
Yeast Balloons
Source Institutions
Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.
Exploring How Robots Move
Source Institutions
In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.
Rooftop Gardens
How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.
DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
Foam Tower
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star
Forensic Science: Hair Sample Investigation
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.
Density Rainbow and the Great Viscosity Race
Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.
