Neural Network Signals
Source Institutions
In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.
Measuring and Protecting Skin
Source Institutions
In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.
Exploring at the Nanoscale
Source Institutions
This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.
Rippin' Rockets
Source Institutions
In this activity, learners work in pairs to conduct a series of experiments using a balloon, drinking straw, and paper.
Weighty Questions
Source Institutions
In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.
Making Regolith
Source Institutions
This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?
Heart and Lungs
Source Institutions
In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.
Visualizing How the Vestibular System Works
Source Institutions
In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the
What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
Living Clocks
Source Institutions
In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.
Try Your Hand at Nano
Source Institutions
This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.
Muscle Fibers
Source Institutions
In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
Paper Drop Design Competition
Source Institutions
Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.
That's the Way the Ball Bounces: Level 1
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.
What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.
Doughy Physics
Source Institutions
Learners drop two different masses of play dough and observe how long it takes them to hit the ground.
Salting Out
Source Institutions
In this activity, learners create a mixture of water, alcohol and permanent marker ink, and then add salt to form a colored alcohol layer on top of a colorless water layer.
Traveling Nanoparticles Model
Source Institutions
This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.
Our Sense of Touch: Two-Point Discrimination
Source Institutions
In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.
