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...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...

Students investigate the 3 states of matter. For this physical science "matter" lesson, students observe and participate in a number of demonstrations involving melting and freezing water. Students observe the effect heat has on changing...

What better way is there to learn about isotopes than to play with them? Chemistry students manipulate the number of protons and neutrons in a hands-on activity. Individuals try to score the largest number of points...

First graders investigate how water can be both a liquid and a solid. They weigh popsicles and observe them as they write in their science journals. They measure the liquid as the popsicle melts and refreeze them to change them back...

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

Students examine the effects of salt on ice. In this salt instructional activity, students observe what happens to the temperature of ice when salt is added, then make ice cream to see how this knowledge can be used.

Students melt colored ice cubes which are created from a funnel, balloons, water, and food coloring. In this ice lesson plan, students put food coloring into water in a balloon, freeze it, and see how the food coloring ended up making...

Students complete activities to learn about the common land features in Alaska. For this land study lesson, students study an overhead for permafrost features. Students define ice wedge polygons, thermokarst, and pingos. Students also...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

In this freezing/melting learning exercise, students observe ice cubes and answer a set of 8 related questions.

Students make a " science surprise" or ice cream in the lab. In this melting point depression lesson plan, students use various substances with ice to determine the effects on the melting point of ice and the ability to make ice cream....

Students experience problem-based learning as they use prior knowledge of the states of matter to keep a frozen juice bar from melting.

How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third lesson of the series, learners conduct an experiment, demonstrating the flow of heat...

Students explain how melting glaciers affect global warming. For this earth science lesson, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Young scholars investigate how salt affects the state of ice. In this ice cream making instructional activity, students change the freezing temperature by adding salt and observing the results. Young scholars use experimentation and...

In this ice and water worksheet, students read about the energy needed to transform ice to liquid water. Students solve 3 problems where they calculate the energy needed to melt ice given different scenarios in space.

After reading an informational text detailing the ins and outs of snowflakes, scholars draw their own special design then work cooperatively to role play a snowman building scenario. 

In 1879, Sir William Crookes discovered the fourth state of matter, plasma. The presentation covers states of matter, phase changes, density, pressure Pascal's Principle, buoyant force, Archimedes' Principle, Bernoulli's Principle,...

Fifth graders examine both physical and chemical changes, and how to identify the difference between the two. They observe the changes that occur in butter when it is exposed to heat and cold, heat energy. In their notebooks, they write...

Middle schoolers investigate how ocean currents affect our world. In this ocean currents lesson, students perform an experiment to show how cold water is near the poles and warm water is near the equator. Middle schoolers use...

Students explore the states of water. In this water states lesson, students observe ice over time and the changes that take place. Students read a related text and draw their observations in a journal entry. Students discuss the...

Students review properties of matter and discuss how materials change when things are done to them. They observe how materials change as a reaction to temperature by following the procedure to make ice cream and recording the temperature...
