Astronauts train underwater to simulate the change in gravity. An out-of-this-world unit includes three hands-on activities, one teacher demonstration, and a discussion related to some of the challenges astronauts face. Scholars apply...

Hot off the presses, this collection of thermal energy activities, lessons, and printables is sure to amaze. Demonstrate how thermal energy moves about in a system using simple materials. Pupils demonstrate their understanding...

Not only does a concave mirror focus light waves, it can also concentrate infrared radiation into a hot spot. If you have a small electric heater and such a mirror, demonstrate this for your physical science class.

Whether you want to heat things up in science class or cool things down a bit, an intriguing lab's got you covered! Science scholars explore the principles of thermodynamics using a solar oven, then change the conditions to turn their...

Mid-ocean ridges, rift valleys, island arcs, mountain ranges, earthquakes, volcanoes ... there are so many features associated with plate tectonics. The 14th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography...

An informative physics lesson includes two teacher demonstrations, one on AC currents and the other on DC currents, allowing pupils to take notes while watching. The resource includes questions to assign as homework or...

Introduce materials science with a class demonstration. After showing a PowerPoint presentation on materials and their properties, instructors provide a ceramic tile, a Popsicle stick, a paper clip, and a plastic bag as examples of...

Carbon dioxide is a very important gas; it is present in the air, used in cooking, and supports plant and animal life. Scholars investigate the properties of carbon dioxide with three different activities. They experience a color change,...

Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Young geologists get a glimpse beneath the earth's surface in this plate tectonics investigation. After first learning about the different layers of the earth and the constant movement of its plates, young...

Explore the properties of gases through one activity and two investigations in which super scientists observe the changes gas makes when encountering different conditions.
