Scientific procedures ensure valid data and valid results. Use a water sampling interactive to teach learners the procedures for collecting water samples. The interactive takes users through the process step-by-step with notes of...

Create a winning card. Given a description of a bingo game using two spinners, pupils determine which of three cards has the greatest chance of winning. Scholars then determine which are the best numbers to put on their own cards to give...

Go on a moon mining expedition from the safety of your classroom with this space exploration simulation. Using simple models of the moon's surface prepared ahead of time by the teacher, young scientists are challenged with locating and...

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space...

Introduce the topic of astrobiology in a unit that's out of this world. Biology scholars examine the search for extraterrestrial life by culturing roundworms, a species that has been key in helping researchers understand the...

Oceans absorb half of the carbon dioxide and 80 percent of the greenhouse gases released into the atmosphere. Scholars learn how and why the oceans store heat more effectively than land and how they help mitigate global warming. Pupils...

In groups, young environmentalists investigate water samples that are contaminated with different types of pollutants. Each group presents their findings to the class and fills out the "Types of Pollutants Chart." This lesson is meant...

Take the old baking soda and vinegar volcano to the next level by using it to study repeated lava flows over time, examine geologic features on Earth and Mars, and speculate about some of the formations on Mars. 

You may not be able to take a field trip to the moon, but that doesn't mean your class can't study moon rocks. Using graham crackers as the moon's bedrock and powdered donuts as micrometeorites, young scientists simulate...

How do greenhouse gases affect the climate on Earth?  Pupils explore the concept by first building their own apparatuses to model the greenhouse effect. Then, they record data to measure temperature change and determine...

Take young geologists on an exploration of the rock cycle with this six-lesson earth science unit on rocks and minerals. Through a series of discussions, demonstrations, and hands-on investigations your class will learn...

Snow, ice, and water are all composed of H2O. Does that mean they all have the same volume? Discover the ways that the densities of these substances determine their volumes, and how they change based on their current states of...

Introduce learners to set of complete instructions that describe how to build a magnetometer that works just like the ones professional photographers use to predict auroras. The diagrams are wonderfully descriptive, and the written...

Scholars become rocket scientists as they take off on a journey exploring Newton's laws of motion. After learning the laws of motion, pupils design their own investigations using straw rockets. They highlight their literacy skills in a...

What is the universal breakfast? The resource includes two activities, the first one observing oatmeal to understand the texture of the universe. Then, scholars measure raisin bread dough before and after it rises to represent the...

Astronomy is literally over your head, but this lesson will explain how we study it. Young scientists make telescopes, calculate and compare the light gathering power of lenses, and simulate detection of infared radiation....

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...
