The classic "Egg Drop Activity" is described in this fine science lesson plan. Young scientists work together to design a container that will protect the eggs inside of it when dropped from a high place. Lots of good scientific...

How can December 21 be the shortest day of the year when all days are 24 hours long? Pupils see how to build a model showing the differences between winter and summer solstices and equinoxes. Using this model, classes can then discuss...

Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Young scholars design a solar still and purify water.  In this earth process and design lesson, students observe how the heat of the sun helps to purify water. Young scholars analyze why this could be helpful on a desert...

Here is a great way to get pupils to express a scientific concept in a fun way. After hearing the story of Walter the Water drop and learning facts about the water cycle, the class will write a creative expository piece describing what...

Electricity travels at the speed of light, 186,000 miles per second. Through a simulation, classes see how the structure of energy bands in crystals of atoms determines how materials conduct electricity. Participants can change the...

The winds of change are blowing in our very own solar system!  But what makes some heavenly bodies more affected by solar winds than others?  Pupils discover the concept of magnetic forces at work in space in this...

A challenging activity helps young geographers explore the temperatures around the world! They study how the Earth's land temperatures are affected by their proximity to an ocean, as well their latitude and their altitude. A very...

Scientists need to figure out how to measure interplanetary magnetic fields, but the magnetic field of the spacecraft is interfering with their readings. Scholars attempt to solve the problem that has perplexed NASA scientists for years.

Looking for a good worksheet to help teach about the planet Saturn? This worksheet is for you! An excellent photograph of Saturn accompanies three paragraphs of text. Pupils answer five multiple choice questions based on what they've...

Looking for a good worksheet to help teach about the planet Venus? This worksheet is for you! An excellent photograph of Venus accompanies three paragraphs of text. Learners answer five multiple choice questions based on what they've...

After reading a short excerpt about Mercury, your class will answer four comprehension questions. The worksheet challenges them to fold over the paper and answer the questions without referring back to the excerpt. An answer sheet is...

"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

Students study the Earth and Solar System through a variety of activities. They compile a coloring book show the characteristics of the Sun and nine planets.

Eight slides of information related to shifts in the climate make up this presentation. The vocabulary and concepts displayed are geared toward high school meteorology learners. Content is not cohesive from slide to slide, but the...

In this solar system instructional activity, students read about the planets, asteroids, meteoroids, comets, and the moon. Then students complete 25 multiple choice, 4 true or false, and 3 short answer questions.

Students identify the most common causes of global warming. In this earth science lesson plan, students use an interactive website to explore changes over time in sea ice, sea level, carbon emissions, and average global temperature. They...

For this science:  space quiz worksheet, students answer twenty questions, not interactively, about outer space, then scroll down to find the answers.

Students construct a simple robotic energy transformer. In this space science lesson, students explain how energy is transformed from one form to another. They identify the different uses of robotic devices.

Students explore a variety of ways of how to care for the environment in the nine lessons of this unit. They observe how to be responsible "Earth Kids."
