Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.
Describing Oak Leaves
Source Institutions
Learners work in teams to investigate how scientists use physical characteristics to classify living things.
A Simple Escapement Mechanism
Source Institutions
In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.
Mirror Image
Source Institutions
In this activity, learners investigate procedural memory.
Simulation of Laparoscopic Surgery Lab
Source Institutions
This simulation of laparoscopic surgery enables learners to practice and to learn this modern surgical technique.
Mapping the Classroom
Source Institutions
In this activity, learners discover the importance of maps and scale as they work together to create a map of the classroom.
The Carbon Cycle: How It Works
Source Institutions
In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another
What's the Angle?
Source Institutions
This activity helps learners understand how the angle of the Sun affects temperatures around the globe.
Multi-Variable Relations: Stressed to the Breaking Point
Source Institutions
In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.
Design a Safer Bicycle Helmet
Source Institutions
In this activity, learners design a bicycle helmet. Participants will explore the design of bicycle helmets to gain an appreciation for the role that helmet layers play protecting the head.
Diatom Ooze: Ooze Clues
Source Institutions
In this activity, learners will plot the distribution of various oozes using information from sediment maps.
How Long Can You Hold Your Breath?
Source Institutions
In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.
Pitch, Roll and Yaw: The Three Axes of Rotation
Source Institutions
In this activity (page 87 of the PDF), learners move their bodies to better understand the three axes of rotation: pitch, roll and yaw.
Wheat Germ DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.
Motorized Balancing Toy
Source Institutions
In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.
Indicating Electrolysis
Source Institutions
In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.
Regolith Formation
Source Institutions
In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.
The Ins and Outs of Tides: Learn About Causes and Predictions
Source Institutions
In this activity, learners will compare predicted and observed tides using data from The National Oceanic and Atmospheric Administration(NOAA).
Make Your Own Telescope
Source Institutions
Discover how a refracting telescope works by making one from scratch using common items. This telescope won't have a tube so the learner can see how an image is formed inside the telescope.
Mapping the Homunculus
Source Institutions
In this activity, learners will explore how the human brain interprets environmental stimuli.
