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...

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...

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...

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. 

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...
