Are All Asteroids' Surfaces the Same Age?
There are more than 600,000 asteroids in our solar system. Pupils analyze images of two asteroids in order to determine if they are the same age. They count craters for each asteroid and compare numbers.

Analyzing Tiny Samples Using a Search for the Beginning Mass Spectrometry
Teach the basics of mass spectrometry with a hands-on lesson. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative abundance and...

Just How Far is That Star?
Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires critical...

The Evidence is “Clear”!
Do you think you know better? Become a scientist and prove it. Scholars review the evidence for two different theories of the origins of the universe. They notice the empirical observations as well as the inferences to determine which is...

Planet Designer: Kelvin Climb
It's time to get those creative juices flowing! This second instructional activity in a series of five continues allowing pupils to design their own planets. It the same format as the first, but, this time, allows students to alter...

Photons in the Radiative Zone: Which Way Is Out? An A-Maz-ing Model
Can you move like a photon? Young scholars use a maze to reproduce the straight line motion of a photon. The second in a six-part series of lessons on the sun has learners measure angle of incidence and refraction to determine the path...

The Invisible Sun: How Hot Is It?
It's getting hot in here! The first in a series of six lessons has learners model nuclear fusion with a simple lab investigation. Groups collect data and analyze results, comparing their models to the actual process along the way.

Determining the Nature, Size, and Age of the Universe
Prompt scholars to discover the expansion of the universe themselves. Using photographs of other galaxies, they measure and then graph the size and distance of each. Finally, they draw conclusions and prove the universe is expanding.

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...

Trends of Snow Cover and Temperature in Alaska
Students gather historical snow cover and temperature data from the MY NASA DATA Web site. They compare this data to data gathered using ground measurements from the ALISON Web site for Shageluk Lake. They graph both sets of data and...

Measuring Dark Energy
You're only 10 minutes late? Do you know how much the universe has expanded in those 10 minutes? Scholars graph supernovae based on their redshift and see if the results verify Hubble's Law. If it does confirm it, the universe is...

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.

Discovering the Milky Way
What do you call a tiny collection of galaxies? A puny-verse! Young scholars graph data gathered by scientists studying Cepheids. They attempt to identify a relationship between the variables through standard and logarithmical graphing....
