In this activity, students compare two images of the Crab Nebula taken more than 40 years apart. By measuring the motion of some of the knots of glowing gas in the neubla, students will be able to determine the date of the supernova explosion that... (View More)

The front of this poster is a cartoon profile of the atmosphere, showing the "good and bad" roles of ozone in the stratosphere, high troposphere, mid-troposphere, and surface. On the back is an article for students, beginning with an explanation of... (View More)

This is a lesson about the states of matter. Learners will participate in a kinesthetic activity to reintroduce them to three states of matter, solid, liquid, and gas and introduce them to a fourth state of matter, plasma, its connection to the Sun,... (View More)

The two activities included in this guide introduce students to the principles behind Newton's Law of Gravitation and help students learn aspects of the law in an interesting and engaging way. This guide provides teachers with background information... (View More)

This educational wallsheet provides several simple illustrations of Newton's Second Law. In the activity included, students study the motion shown in the drawings to decide how it relates to the object's velocity, whether or not the velocity is... (View More)

This is an activity about the correlation between annual precipitation and plant productivity in different Earth biomes. Learners consider water evaporation, solubility and abundance relative to life on Earth and relative to finding evidence for... (View More)

In this laboratory activity, students investigate chromophoric dissolved organic matter (CDOM) through gradual dilution of black, green and chamomile tea. Through this activity, students discover how CDOM can dominate the absorption of sunlight, how... (View More)

In this demonstration, a plastic soft drink bottle is used to demonstrate properties of gases and liquids with respect to temperature and pressure. Calculations using the formula for the Ideal Gas Law are included. The resource is from PUMAS -... (View More)

In this activity, students use rulers to measure distances between hypothetical galaxies and then use these distances to calculate the velocities of the galaxies. This activity is part of the "Cosmic Questions" educator's guide that was developed to... (View More)
