If you don't get along with someone, it's said that the two of you are like oil and water. Why is this? Explore the phenomenon and explain the phrase in one resource! Science superstars first observe samples of oil and water together....

Why is there so much frozen water at Earth's poles? Because water is a polar molecule! Young scientists observe polar molecules moving in a mixture of oil and water. They see the changes in potential energy in the hydrophilic and...

Micelles consist of an aggregate of molecules in a colloidal solution. The simulation presents two different ways the molecules assemble into micelles based on the polarity of the solution in which they are placed. Scholars can set the...

How does hydrogen bonding explain ice crystals? An engaging interactive answers just that. Scholars explore how polar molecules interact and observe the changes as temperature fluctuates as well as the hydrogen bond attraction.

Seventh graders simulate a Jeopardy game to examine the chemical nature of water. Among the topics featured are evaporation, water, salt, and temperature. finally, as review, 7th graders answer a battery of questions presented by the...

Students watch an episode depicting the human vs. polar bear conflict in Churchill, Canada. They conduct online research and analyze the information. They interpret the facts and use storytelling techniques and role playing to convey...

Students determine what percentage of the Earth is water and how much water is needed by humans.

Students participate in a demonstration in which they role-play polar bears and habitat components to demonstrate the impacts of climate change on the Arctic Ocean ecosystem.

Can scientists sort molecules based on their interaction with oil and water? The simulation demonstrates how this is possible. Pupils decide when to insert a molecule and observe how they sort themselves based on polarity.

Young scientists explore some of the scientific equipment that is used by explorers during expeditions to the North or South Pole. Then, they have a relay race! All of the equipment is lined up at a spot 25 yards away from the lines. The...

How can organisms light up in water? Bioluminescence is light produced in a chemical reaction that can occur in an organism's body. First, learners determine what happens to light/color as you move into the deep ocean. In groups, they...

Students study the importance of caring for desert water sources. In this desert lesson, students investigate water resources that are available in deserts. They listen to a read aloud about the Sonoran Desert before working in groups...

Students simulate the search for water in Mars using simple apparatus. In this space science lesson, students explain how soil temperature affects the cooling of probes. They graph the data collected from the simulation.

Seventh graders role play the roles of naval engineer apprentices. In groups, they work together to design a ship which cannot be damaged by freezing ice. They use the internet to research the weather and ocean conditions of the water...

Students explore the greenhouse effect and what it does to the environment. They discuss if and how human behavior contributes to global warming and test natural materials for carbon content.

Second graders read and perform a reader's theater version of the story, "Bringing the Rain to Kapiti Plain." They complete a graphic organizer of cause and effect of their part in the story, look up vocabulary words on a dictionary...
