Investigating the Atmosphere - Air Takes Up Space
How do you know there is air? Can you see it, smell it, feel it? To begin the investigation, learners watch a video and discuss what they know about air and the atmosphere. Then, they participate in five different hands-on, inquiry-based...

Strange New Planet
The first remote sensors were people in hot air balloons taking photographs of Earth to make maps. Expose middle school learners to space exploration with the use of remote sensing. Groups explore and make observations of a new...

Atmospheric Layers
Space diving refers to the act of jumping from outer space and falling through Earth's atmosphere before parachuting to land. Scholars learn about this extreme activity and study the layers of the atmosphere they must conquer in the...

Fizzy Balloons - C02 in School
Carbon dioxide is a very important gas; it is present in the air, used in cooking, and supports plant and animal life. Scholars investigate the properties of carbon dioxide with three different activities. They experience a color change,...

Things Are Not Always What They Seem
Science is magic that works. Magical color-changing beads and a coffee can that follows voice commands are just two examples of magic tricks that rely on science. After completing a hands-on activity and an experiment investigating the...

Happy Landings: A Splash or a Splat?
Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...

Let's Break the Particles
Build learning by breaking atoms! Young scientists study the way energy changes with a hands-on activity. As they roll steel marbles down a ramp, learners test the hypothesis that kinetic energy does not go away with friction...

What is Time?
Does it ever seem like time is slipping through your fingers? Model the passing of time with an hourglass activity in which individuals determine whether hourglasses are the most efficient way to measure time.

Cosmic Microwave Background
Begin your next class with a BANG! Pupils discuss the formation of our universe and its expansion before proceeding with an activity designed to demonstrate what most likely occurred billions of years ago. They conclude with a discussion...

Sea Level: On the Rise
With the global temperature on the rise, the effects of climate change are starting to be seen. However, many people have a difficult time conceptualizing the long-term effects, such as sea levels rising. Given an easy and effective...

How Light Pollution Affects the Stars: Magnitude Readers
Did you know light can decrease visibility? Light pollution absolutely makes it more difficult to see stars. Scholars build a simple magnitude reader to determine the magnitude of stars. They use these data to estimate the impact of...

Are All Asteroids' Surfaces the Same Age?
Did you know scientists can tell the age of an asteroid by looking closely at its craters? This final lesson of a six-part series focuses on two asteroids, Gaspra and Ida, in order to demonstrate the concept of dating asteroids. Scholars...

Stellar Fingerprints and Doppler Red Shifts
Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format instructional activity.

What’s the Problem with Isotropy?
Some patterns are so small, we can't see them without the help of technology. The same is true for cosmic microwave background radiation. During this activity and discussion, scholars examine both anisotropic and isotropic items and...

Can Photosynthesis Occur at Saturn?
In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

Supernova Chemistry
By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

Mapping the Field of a Dipole Magnet
High school scientists build their own magnetometer and use it to map the field surrounding a bar magnet. Excellent background resources is included, as well as a diagram of how to build the magnetometer.
