Picturing an Astronomer

This is an activity about assumptions and stereotypes. Learners will first sketch what they perceive an astronomer looks like. After, they will together discuss their images and research the preparation that is required to become an astronomer.

Zooming In

Students examine a series of remotely-sensed images of the US, scaling from the continent to San Francisco, and distinguish the concepts of scale and resolution. At greater resolution, students are able to identify different land classes on the map, using the color key for false color images.

Getting to Know Soil

Each student will make predictions about the properties of various soil samples. Then they will examine several types of soils and record their observations. Next, they will learn about soil profiles and horizons by both examining a soil sample in a jar and by creating a soil profile flip chart.

What Can We Learn About The Sun From Shadows?

This is an activity about light and shadow. Learners will make outdoor sundials. They will use the sundial and the length of the shadow that is cast to explore the relationship between the size and position of the shadows and the position of the Sun in the sky.

Dollar$ or Cent$

It is common in the real world to see mathematical examples where the cents sign was used when the dollar sign was supposed to be used. Converting and comparing decimals and fractions can help clear up this misconception.

Eclipses and Moon Phases

In this lesson, students explore how eclipses happen and why Einstein needed a total eclipse to image stars near the Sun in order to demonstrate how the Sun's mass bends the light from a far away star.

Just How Far is that Star?

In this investigation, students use "point-source" light, light meters, and graphing software to quantify the reduction in light over distance. Through careful measurement of light received at several distances, students discover the best fit of the data is the inverse square rule.

When a Ruler is Too Short

This activity lets students measure distances in the classroom using parallax. The exercise can be done either at a high school level using trigonometric functions, or at a middle school level using simple arithmetic approximations to the trigonometric functions.

Egg Drop Lander

Learners will collaboratively design and build a descent and landing system for an egg. The students will also practice their writing skills by writing a letter or article about the success or failure of their spacecraft design. This is lesson 15 of 16 in the MarsBots learning module.

S'COOL Lesson: Weather BINGO

In this activity, students play the familiar BINGO board game, using predetermined vocabulary terms. Includes detailed procedure and materials, a vocabulary section linked to an on-line glossary.
