Students demonstrate the scientific method by conducting an ice cube melting experiment. They make predictions and observations, and conclude what factors make ice melt more slowly or quickly than normal.

Students examine the effects of salt on ice. In this salt lesson, 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.

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 listen to a read-aloud of fiction and nonfiction books, The Snowy Day, written and illustrated by Ezra Jack Keats, and Snow Is Falling, written by Franklyn Branley and illustrated by Holly Keller, then take part in four creative...

Students conduct an experiment.  In this salinity lesson, students learn about sea ice, why it is important and how changing amounts can affect the sea.  Students conduct an experiment to find out the effects of salinity on the...

What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts. 

Ice cores provide scientists with knowledge of historic melt layers, air temperatures, greenhouse gases, and climate stability. Scholars work in groups to build layers representing snow and ice over thousands of years. Then, groups...

Students examine the different propereties of ice, such as freezing temperature.  In this scientific lesson students complete several activities using ice, like making ice cream.

Students discuss certain properties of salt and how it is used every day as well as harmful uses. They experiment with salt to see it conduct electricity, form crystals and water freezing temperature. They complete a worksheet to record...

Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

Students define the term solution. They explain conservation of energy and energy transfer as it relate to how the milk solution became ice cream. Students are able to explain freezing point depression.

Students investigate the effects of salinity on icebergs. In this hands on lesson, students design and conduct an investigation into how the amount of salt in ice affects its buoyancy.

In these discovering if an ice cube and an orange or lemon will float in water worksheets, students conduct the two experiments, record the results, and answer questions. Students write 18 short answers.

The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...

Students make ice cream as a result of viewing changes of states of matter. In this matter lesson plan, students learn how heating and cooling can effect a state of matter to change.

In this inferences:  an experiment with ice instructional activity, learners follow the procedure for the experiment with ice, then write inferences from their observations.

Students explore the concept of freezing point in an experiment that shows why salt is effective at clearing ice from roadways in the winter. In small groups, they compare the process of making homemade ice cream in plastic bags with and...

Students are shown an experiment making ice cream while discovering the freezing point depression. There are questions for students to answer after the demostration.

Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...

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...

Students explore how chemicals change water. In this chemical change lesson, students participate in an experiment to observe how salt effects ice and how ice cream freezes.

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 investigate melting and freezing behavior in substances. In this melting and freezing points lesson plan, students perform experiments to test the impact of various salts on the freezing point of water, they test the impact of...
