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...

Ocean Acidification
If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

Melting Ice: Designing an Experiment
Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

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...

A Scale Model Solar System
Between the time scientists discovered Pluto and reclassified it as a dwarf planet, it did not even make one full revolution around the sun. In two activities, scholars investigate scale models and their properties. Pupils find that it...

If Hot Air Rises, Why Is it Cold in the Mountains?
Investigate the relationship between temperature and pressure. Learners change the pressure of a sample of air and monitor its temperature. They learn that as air decreases its pressure, its thermal energy converts to kinetic energy.

A Quest for Anomalies
Sometimes scientists learn more from unexpected findings than from routine analysis! Junior oceanographers dive deep to explore hydrothermal vent communities in the fourth lesson plan in a series of five. Scholars examine data and look...

Why Is the Sky Purple?
The color of the sky depends on the time of day. Young scholars experiment with scattering different wavelengths of light to recreate the color of the sky. They observe both the longer blue wavelengths and the shorter red and orange...

Mapping the Deep-Ocean Floor
How do you create a map of the ocean floor without getting wet? Middle school oceanographers discover the process of bathymetric mapping in the third installment in a five-part series of lessons designed for seventh and eighth graders....
Colorado State University
How Can Clouds Keep the Air Warmer?
Condensing water warms the air around it. Young scholars consider this concept as they experiment with air temperature around evaporating and condensing water vapor. They simulate the formation of clouds to experience the associated...

Study Jams! Gravity & Inertia
Is it possible to defy gravity? Not really. With force and inertia, we can act against it for a little while, but, eventually, gravitational force will pull us back to Earth. The relationships among mass, force, and inertia are all...
