Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

Using spectroscopes, high school astronomy, physics, or chemistry learners observe emission spectra from several different sources. This stellar NASA-produced lesson plan provides terrific teacher's notes and a student handout. Make sure...

Students use real satellite data to determine the changes in near-surface air temperature at different times of the year over the Caribbean Sea. They discover how Earth's tilt causes seasonal differences in incoming solar energy. They...

Two scenarios are presented for chemistry detectives to decipher. Both require the use of an infrared spectrometer and focus on the examination of polymer materials. In the first, lumps in polyethylene bottles are analyzed. In the...

This lab activity is geared toward experienced chemistry learners, in particular, those who are familiar with organic chemistry. They will create a synthetic elastomer  and then make observations and measurements of its different...

Share pupil responses to an interactive slide show about a design initiative intended to help the world's poor. The class works in groups to brainstorm ideas, and then prepares sketches of their own design solutions. Each rendering...

Physics apprentices analyze the impact of NASA's Impactor as it collided with the comet Tempel 1 in July of 2005. They calculate the mass and speed of the comet, along with the distance it might drift off of its orbit over time. This...

A huge slide show provides a review of almost every topic there is to cover in basic chemistry! Your young scientists will be interested to see each illustration and example given. The appearance of the 120 slides varies greatly, most...

Challenge your physics class to implement their knowledge of electric fields by completing this activity as homework. There are 15 problems to solve, for which pupils compute electrostatic force, electric field strength, and electric...

Real world chemical reactions are used as examples for teaching stoichiometry. Viewers work through air bag inflation, fat conversion to water in a camel, rocket fuel combustion, and carbon dioxide removal in spacecraft. Make...

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

From start to finish, this is a truly excellent lesson plan addressing the epidemic of diet-related disease in the United States. Learners begin with a reading excerpt of detailed information on trends in the American diet and the...

Greek alphabet letters are used to represent words or values in science and math. Keep a list on hand to refer to while working through calculus or physics problems.

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

Looking for a hot date? Pick any day in August, statistically the hottest month in the United States. The 15th instructional activity in the series of 21 instructs pupils to investigate the August 2007 heat wave through NASA data, daily...

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

Model an oil spill cleanup. An engaging engineering lesson has groups using aerogels to simulate an oil spill cleanup (vegetable oil in water). Along the way, they learn about nanotechnology and hydrophilia/hydrophobia.

For this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

It may be time to get to know the skeletons in your family. The first lesson in a series of 5, introduces the class to the concept of osteoporosis. The class members brainstorm possible causes and whether the family should be concerned...
