How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Water temperatures connect to the movement of the ocean. Pupils read two articles about the temperature and the motion of the oceans before small groups investigate the interaction of hot and cold water. Team members add cold and hot...

The difference between sinking and floating may be a little salt. Young experimenters analyze the effect of salt and temperature on the density of water. They use their results to predict the effect of climate change on ocean ecosystems.

With global temperatures on the rise faster than ever recorded, the effects of a heating planet could be devastating. Allow learners to discover just what the world is in store for if the warming continues through a series of videos, a...

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...

Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

Scholars make a model to discover how the force of trade winds over the Pacific Ocean creates an El Niño. Super scientists observe how the severe weather affects life in water and on land. 

What adaptations exist in order for icefish to survive the subfreezing temperatures of the Antarctic Ocean? Middle and high schoolers can find out through watching a related 13-minute video and performing a simple investigation to...

Learners investigate how solar energy is converted into heat in part two of the 10-part Discover Your Changing World series. They build and test homemade solar cookers to boil water and cook rice. Pupils consider the impact of heat...

Subtracting negative numbers can be confusing to your middle schoolers. Here, they are able to draw a number line and put their answer in sentence form to check their understanding of negative numbers. 

There's a little bit about every aspect of weather in this trivia game. The lesson resource provides 36 questions and answers pertaining to four different topics related to weather: effects, science, technology, and statistics. Groups...

For this editing worksheet, student read a 4-sentence paragraph while looking for capitalization, punctuation, spelling, and grammatical errors.

If you've ever so much as watched a news clip about a hurricane, you probably know that hurricanes draw their power from warm ocean waters. If that is true, does it mean that hurricanes actually cool the ocean down when they pass...

Ocean currents have a profound effect on the climates of the continents, especially those regions bordering on the ocean. The Gulf Stream makes northwest Europe much more temperate than any other region at the same latitude, and the...

In this project you can use archived satellite tracking data to learn about activity patterns of harbor porpoises. How far do they travel? Can you find patterns in the routes individual animals take? Can you correlate their route with...

We've all heard that hurricanes draw their immense power from warm ocean waters. Of course, many factors contribute to the formation and growth of a hurricane, but can we expect to find that the warmer the water, the stronger the...

This activity makes use of the Temperature Probe to measure the temperature of water as it cools and freezes. Students' determine and compare the freezing temperature of fresh water and ocean water.

This experiment allows your students to study the effect of temperature on water motion and also to create their own density driven current.

For this activity, students will investigate how temperature and currents affect the salinity of ocean water, making predictions after studying ocean maps. It is recommended that teachers do the experiment themselves before presenting it...

Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to...

Of course it can, you say: ice is water and ice floats. And you're right. But we're talking about water in the liquid phase Can liquid water float on water? The goal of this project is to investigate what happens to layers of water with...

Students will learn about how the Earth's carbon cycle works, as they examine the relationship between levels of carbon dioxide and water vapor in the atmosphere and the temperature of the ocean's surface. Includes online student...

Melting sea ice doesn't cause sea level to rise because the ice is already in the ocean, but it does cause other changes to the planet. When sea ice melts, more sunlight is absorbed by the Earth, which causes more warming. It's a vicious...
