Milk Carton Boats
Source Institutions
This activity (on page 2 of the PDF SciGirls Activity: Milk Carton Boat) is a full inquiry investigation into boat hull design.
Design and Build a Wind Vane
Source Institutions
In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.
Airfoils
Source Institutions
In this experiment, learners discover how an airfoil creates lift. Learners use simple materials to build an airfoil and test it at different angles to investigate Bernoulli's principle.
What is a "Model"?
Source Institutions
In this activity, learners simulate the behavior of the atmosphere.
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
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.
Target Practice
Source Institutions
In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
Exploring Earth: Temperature Mapping
Source Institutions
This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
Make Your Own Mini Mini Golf Course
Source Institutions
Build your own Mini Mini Golf Course and learn about hands-on building and design, basic circuitry, motion modules and more!
Chemistry Makes Scents
Source Institutions
In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.
Balloon Rockets
Source Institutions
In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.
The Crayon Rock Cycle
Source Institutions
In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.
Crazy Camouflage
Source Institutions
In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.
Crazy About Kites
Source Institutions
In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.
Self-Assembly Game
Source Institutions
This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.
Exploring Black Holes and Gravity
Source Institutions
This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.
Newspaper Bridges
Source Institutions
In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.
Skewers and Garden Poles
Source Institutions
In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
Lift Experiment
Source Institutions
In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.
