Science 4 Inquiry
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...

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...

The Dynamic Nature of the Sun
In this second lesson of the series, pupils learn to observe similarities and differences in photos of the sun and record them in a Venn diagram. Then, small groups practice the same skill on unique images before presenting their...

Discovering Some of Your “Yardsticks” Are Actually “Meter-sticks”
The Milky Way gets great reviews on Trip Advisor — 100 million stars. The activity allows scholars to rethink their assumptions and prior knowledge. Pupils observe a set of two lights at equal distance and brightness, but they believe...

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...

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.

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...

Incoming Asteroid! What's the Problem?
Oh, no! An asteroid is on a collision course with Earth!. Class members must rise to the challenge of designing a shelter that will protect people from the impact and permit them to live in this shelter for one year. In this first lesson...
