In this planet worksheet, 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...

In this black holes worksheet, students solve three problems about black holes using given equations for determining the temperature of the gases in a black hole and the visible light from the black hole at given temperatures.

In this solar system worksheet, students fill in the blank to sentences that refer to the solar system. Students fill in 15 blanks with planet names.

In this atoms worksheet, students complete 58 questions about the atomic radius of atoms, the ionization energy, the valence electrons, metals, non-metals and semi-metals and the families of elements.

In this grade 4 geography worksheet, 4th graders complete a total of 25 multiple choice questions relating to 4th grade geography concepts. An answer key is provided.

Students research information about the current Olympic research. In this Olympic research lesson, students take a pre-test to determine their knowledge about the current Summer Olympics. They choose one of three areas to research and...

In this algebra worksheet, 11th graders graph parabolas and figure out the major axis and minor axis of the graph. They also find the focus. There are 4 problems on this worksheet.

Students study the unique environment of the moon and Mars. In this space science lesson, students design a city located in the outer space. They create a computer aided design, models or drawings of their cities and share them with the...

Learners examine what iridium flares are and when they occur.  In this iridium flare lesson students complete an activity to see how far overhead Iridium satellites are.

In this solar system worksheet, students use foldable models they made of the planets to answer questions about each planet. They answer questions about the theories and predictions made in our history about the solar system and answer...

Students practice finding the location of cities across the world by using an interactive Web site, and figure out the world's time and the value of time zones the world over.

Sixth graders complete a WebQuest to study the names and locations of the planets in the solar system. They investigate the causes of the seasons and the distance between the planets using astronomical units. They use technology to...

Eighth graders construct various machines and compare the work done by them.

Students explore why when you examine the moon depends on its location in relationship to the sun and Earth. The moon never goes away or changes shape-we just see a different fraction of sunlight being reflected from the moon to Earth.

Students explore basic principles of seasonal change, ponder the mechanisms that drive these changes, and perform experiments that show what causes the earth to heat differently during different seasons.

Second graders recall the affect of direct and angled sunlight on the seasons, describe some results of warming soil and air in spring, predict the changes in buds when twigs are placed in water, and taste a product of tree sap and...

High schoolers calculate their yearly exposure rate to harmful high-energy radiation and cumulative effects over time. They use the information to evaluate the various sources of radiation that are of greatest concern for them.

Students examine the positions of the nine planets in respect to our solar system and explain the unique characteristics of each planet.

Learners design and build a working catapult or trebuchet to explore the concepts of force, motion, and distance.

High schoolers use computer images to explain why the Earth has seasons and examine the phases of the moon. They create 3-D images and present them to the class. They answer a series of questions at the end of the lesson.

Students figure out how to design their own space station. They take a tour on the International Space Station to see what living there is really like, and how lessons learned on the ISS help pave the way for future space tourists.

Junior geometers practice stating the names of different geometric shapes. They define and name the different shapes and compare and contrast shapes to one another. They also relate the shapes to objects in the real world.
