This is an activity about color. Participants will use scientific practices to investigate answers to questions involving the color of the sky, sunsets, the Sun, and oceans. This activity requires use of a clear acrylic or glass container to hold... (View More)

Audience: Informal education

This lesson includes a demonstration to show why the sky is blue and why sunsets and sunrises are orange. Learners will use scientific practices to investigate answers to questions involving the color of the sky, sunsets, the Sun, and oceans.... (View More)

In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

This is a lesson about the formation of glaciers, ice layering and stratigraphy, and the cryosphere and cryobotics. Learners will collect evidence of layering, explore the science story that layering tells, study snow and ice for insights into... (View More)

In this activity, student teams design small-scale physical models of hot and cold planets, (Venus and Mars), and learn that small scale models allow researchers to determine how much larger systems function. There is both a team challenge and... (View More)

In this activity, student teams learn about research design and design a controlled experiment exploring the relationship between a hypothetical planet, an energy source, and distance. They analyze the data and derive an equation to describe the... (View More)

In this activity, students pose several hypotheses for what will happen if you continue heating or supplying energy to the hot and cold planet models (Mercury, Mars, Venus, and Earth) and then test their hypotheses using a spreadsheet based... (View More)
