Students investigate with radio waves that are used to remotely sense the topography beneath the ice sheet. They experiment with travel time of waves and convert data to distance and depth. As a result, they develop a profile of the...

Pupils explore the states of matter. In this physical science instructional activity, students observe what happens to water when it freezes and record observations. Pupils then observe ice when it melts and record observations.

Students study the liquid and solid states of water. For this water states lesson, students complete three experiments to study water as it cycles from a liquid state to a solid state and back. Students finish with a Venn Diagram...

Demonstrate how ice floats on water and get the class thinking about why icebergs are so deceiving. Investigators then experiment with mixing water of the same temperature and water of different temperatures. Make sure to explain the...

The earth sciences are the focus for this Jeopardy-style review game. Categories include geology, space, scientific investigation, meteorology, and oceanography. Diagrams and pictures are involved with most of the questions, making this...

Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...

Study heat transfer with activities that focus on how heat energy works. Using a solar cooker, ice cubes, and heat transfer bracelets, kids experiment and record what they find by keeping ice cubes cold and vegetables hot.

Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based lesson includes a range of learning experiences, from experimenting with the rate at which ice melts...

Find an explanation for the sea level rise. Pupils investigate the difference that melting land ice and sea ice have on the sea level. Groups create two models—one with ice on land and one with ice in the water. As the ice melts, teams...

What is reflectivity, and what does it have to do with the Earth's climate? As reflectivity is measured by albedo, scientists can gather information on Earth's energy balances that relate to global warming or climate change. Budding...

You can't unring a bell, but can you unmelt an ice cube? Readers consider reversible and irreversible changes with a short informational reading passage and accompanying comprehension questions.

Engage young scientists in the upper-elementary and middle school grades with this collection of simple experiments. Whether you're teaching about heat transfer, density, or potential energy this resource has a lab for you.

Learners conduct an experiment. For this forms of water lesson, students observe ice to see what changes take place and then write in their journal about what they observed.

Students discuss the three states of matter and how they are affected by temperature. They make ice cream in a bag while observing how temperature change affects the mixture. They discuss why some specimens froze more quickly than others...

Through three activities, first-time physical scientists wonder at the properties of water. Freeze some soda cans and a container of water prior to the investigation to show that water expands when frozen. Lab groups experiement with...

Learners explore the process of melting or cutting ice. In this scientific observation lesson, students discover that the pressure from two weights will pull a string through an ice cube by melting the ice directly under the line of...

Students analyze earth science by creating a frozen treat in class. In this heat transfer instructional activity, students discuss how matter is transformed from solid to liquid and liquid to gas when energy is removed from the equation....

Students participate in various air experiments to understand that air is all around us. For this states of matter lesson, students focus on the role of air in the water cycle. Students understand that air is densest near the ground....

Students investigate how water goes from a solid to a liquid then back again.  In this experimental instructional activity students conduct their own experiment and see how water changes form. 

In this science worksheet, students will learn the scientific process by doing an experiment about how ice cream melts. There are 5 detailed questions to answer.

Learners 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...

Why do some materials feel cool to the touch, but not others? Learn about thermal conductors and thermal insulators with a fun science experiment. First, kids read the results of an experiment with spoons and hot water. They then try...

Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...
