Will tomorrow's soccer game be rained out? That depends on the water cycle. An animated feature explains precipitation, evaporation, transpiration, and condensation with diagrams and dialogue between Sam and RJ as they huddle under a...

Students complete activities where they observe the amount of freshwater in the world as a fraction of the actual amount of water using different mixtures. In this freshwater lesson plan, students brainstorm on how to preserve...

Students participate in a role play where they play clouds, the ocean, rain drops, and more in order to learn about the water cycle. For this water cycle lesson plan, students have discussions and learn vocabulary.

The tide will turn in your earth science or oceanography unit when viewers see this clip. They learn that tides are caused by the gravitational pull of our moon, and are even impacted by the gravity of the sun. High, low, neap, and...

Blow your class away with a gust of humor as they watch this video about air pressure and wind. Along the way, they find that the density of air (as determined by temperature, altitude, and water vapor content) leads to air pressure...

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...

Our scholarly friends head to the lake to go fishing and are unpleasantly surprised by the algae filling the water. They talk about primary and secondary succession as different ways that ecosystems are changed. Show the short video,...

It doesn't matter if you look on land, in the air, underground, or in water—evolution is everywhere. Scholars complete worksheets with multiple question types as they progress through six online missions creating phylogenic trees. 

Pretty pictures of water droplets, clouds, and snow-covered mountains are the backdrop for information about clouds and precipitation. With 10 slides in all, viewers see how and where clouds form as well as what forms of water can fall...

One friend explains to another that plants combine water and carbon dioxide with the energy of the sun to produce sugar and oxygen. She mentions the roles of the roots, chloroplasts, and stomata in an engaging video that reviews how...

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...

Mia's friends are fish-sitting while she is away on vacation. Zoe divulges to Sam that different animals need different habitats, and that there are both freshwater and saltwater ecosystems. Examples of the kinds of organisms found in...

Introducing your class to weather concepts is a breeze with this fresh film! It differentiates between weather and climate, describes the factors that affect weather (temperature, air pressure and humidity), and displays Earth's climate...

Why does a seastar sink, but a jellyfish float? Through a fun investigation, learners examine the concept of buoyancy using simple household items. The challenge: create neutral buoyancy for an action figure in water. With ample...

A critical look into the structure and function of ecosystems is here for young learners as a series of lessons and worksheet activities. Topics covered include land-based and marine ecosystems, connections to the water cycle, food...

Enjoy beautiful images and ocean facts together with the slide show, then see how much you absorbed by taking the quiz. Some of the topics covered in the presentation include water pressure, sunlight in the ocean, the names and locations...

A sign that washed away from Hurricane Sandy in 2012 beached itself 3,595 miles away in France. This artifact and others from around the world help scientists understand water currents and the far-reaching impact of hurricanes. Scholars...

The greenhouse effect warms up earth enough so it can support life, but if it heats up too much, life won't be able to survive. An interactive presentation covers the greenhouse effect, the carbon cycle, climate forcing, and climate...

It's hot today, but is that the weather or the climate? This colorful presentation isolates both concepts to allow for better understanding by covering the positioning of the planet, making comparisons of land versus water, and looking...

Because they are reactive with air and water, scientists store alkalis in oil. Scholars complete a series of four puzzles reviewing information about alkalis. They match the alkali to its formula, the salt formed with H2SO4, and the salt...

When water is a solvent in a chemical equation, we consider it an aqueous solution. Scholars match the name of four states of matter to their proper symbol in a chemical equation. Four puzzles provide repetition to help pupils remember...
