# Beautiful Earth Water Density Experiments

Designed as either a demonstration or an investigation for use in a formal or informal setting, this activity focuses on the effects of water density on water's movement. A list of materials, along with the instructions for building the apparatus... (View More)

# Why is There a Tidal Bulge Opposite the Moon?

In this activity, students use mathematics to understand tides and gravitation and how gravity works across astronomical distances, using an apparatus made from a slinky, meter stick, and a hook. A description of the mathematical relationships seen... (View More)

# Supernova Explosions

In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star. They are then introduced to the life cycle of a star and how a star's mass affects its process of fusion and... (View More)

# 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. Using a foam ball and a lamp, learners create a... (View More)

Audience: Middle school
Materials Cost: \$1 - \$5 per group of students

# Einstein's Gravity

In this lesson, students will read the 1919 edition of the Cosmic Times (see related resources) and respond by raising questions to be answered with further research. They will make a model of curved space to view the motion of spheres as explained... (View More)

Audience: High school
Materials Cost: \$1 - \$5 per group of students

# Gravitational Waves

The purpose of this lesson is to model for students gravitational waves and how they are created. Students will build a simple "Gravitational Wave Demonstrator" using inexpensive materials (plastic wrap, plastic cups, water, food coloring, and... (View More)

# Potato Float

This is a hands-on lab activity about seawater density, specifically the relationship between density of fluid, weight of an object, and buoyancy. Learners will develop hypotheses and observe a demonstration of density to understand its role in... (View More)

# Stellar Illumination

This is a lesson about discovering distant planets using an Earth-based observing technique called stellar occultation. Learners will explore how a stellar occultation occurs, how planetary atmospheres can be discovered, and how planetary diameters... (View More)

# Barometer Basics

This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two... (View More)

# Seeing Interference Fringes

In this demonstration, students detect the interference of waves and measure wave phenomena using an experimental apparatus consisting of a laser pointer, a second surface mirror scrap (like a bathroom mirror) binder clips, razor blade, ruler, and a... (View More)
