Everything you have ever wanted to know about our solar system, space exploration, and more can be found here. Be prepared to clear your schedule; you will be sucked into the app like a star into a black hole.

What happens at the end of a plant's life cycle? Show kids the natural way that plants show that they're decomposing, as well as the importance of compost, with a lesson plan about living organisms. After reading Log Cabin by Anne...

Writing prompts are great because you can usually find one for any holiday or event. Have your class help the Lorax in his quest to spread the word about Earth Day and environmental awareness with a short printable prompt. The page...

In this planet activity, students read about finding the temperature of a planet using the distance to its star, its reflectivity and the luminosity of the star. Students use a given equation to determine the surface...

Students study robotic spacecrafts that have provided detailed information about the inner and outer planets. In this exploring the planets lesson plan, students use posters and diagrams to study the various robotic spacecraft sent to...

The first remote sensors were people in hot air balloons taking photographs of Earth to make maps. Expose middle school learners to space exploration with the use of remote sensing. Groups explore and make observations of a new...

Here's a reading exercise that uses an article about the inner planets to assess comprehension. After reading the article, kids respond to a series of questions using information from the text.

Researchers think they have evidence of a new planet deep in our solar system that is the size of Neptune and orbits the sun far beyond Pluto. The orbit simulator shows the orbits of our well-known planets, as well as Pluto and the comet...

Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...

The climate at the equator is hotter than the climate at the poles, but why? The lesson goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong lamp,...

Your learners have probably heard of climate change, but do they really understand what it is? Study the history, details, and future implications of global warming and the greenhouse effect with a set of activities designed for an...

Young geologists piece together the puzzle of plate tectonics in an earth science lesson. Given a physical map of the world, they search for land formations that indicate the location of different types of plate boundaries.

There are more than 600,000 asteroids in our solar system. Pupils analyze images of two asteroids in order to determine if they are the same age. They count craters for each asteroid and compare numbers. 

Did you know scientists can tell the age of an asteroid by looking closely at its craters? This final activity of a six-part series focuses on two asteroids, Gaspra and Ida, in order to demonstrate the concept of dating asteroids....

Learn about radiation, convection, and conduction with a multiple choice worksheet. Each question prompts kids to decide what is different about each form of heat energy transfer, and what is the same.

Skeeters are used to model linear and exponential population growth in a wonderfully organized lesson plan including teachers' and students' notes, an assignment, graphs, tables, and equations. Filled with constant deep-reaching...

Break down light into spectra. Scholars learn how atoms emit and absorb photons and come to understand how this process allows scientists to identify different atoms based on either absorption lines or emission lines. Learners then...

Scholars generate and collect pure oxygen through a decomposition reaction of hydrogen peroxide in the fourth lesson of an 11-part series. Then, they complete six investigations into the properties of oxygen.   

Find out if your class agrees with Ice Age: Continental Drift ... or if it's just a fun family movie! Class members research the theory of continental drift, examine evidence of plate tectonics, connect...

Students craft planets from clay. For this geography skills lesson, students create model planets that mimic the geographic features found on Earth as well as the other planets. Students conduct research about characteristics of the...

Students examine the Earth's magnetosphere and observe the effects of the sun's energy on it. They discover the difference between true north and magnetic north. They also explore how solar cells convert solar energy to electricity.

After reading five short paragraphs about planet earth, students must answer 4 comprehension questions about the topic. This worksheet provides great practice for state testing in language arts. 

Students investigate the magnitude of Earth's magnetic field using PASCO. In this physics lesson, students describe the features of the magnetosphere. They explain how atmosphere layers protect the Earth.

Students construct a sketch of the planets in our solar system using concentric circles and angles. For this solar system lesson plan, students plot the position of each planet on concentric circles using graph paper. The sun is included...
