Students observe the chemical reaction that occurs when salt is put on ice, and use the energy that is released to make ice cream.

Students study the concept of ice energy. In this ice energy lesson, students observe what happens when salt is sprinkled on a piece of ice before following a recipe to make two types of ice cream. They note the difference in the two...

In this recognizing different types of changes instructional activity, students answer questions about such things as reversible change, irreversible process, climatic change, filtration process, physical change, and change in the state...

Students participate in experiments to visualize the differences between chemical and physical changes. They attempt to detect the five characteristics of a chemical change.

Students investigate molecule movement according to the kinetic molecular theory. In this kinetic molecular theory lesson plan, students observe demonstrations showing that molecules speed up with increasing temperature and slow down...

In this weird water worksheet, students read for information and assess comprehension. In this true and false, fill in the blank, and multiple choice worksheet, students answer ten questions.

Eighth graders analyze questions posted on a large poster in the room and work in groups to record their response to the question on paper, rotating to the next question after two minutes have passed. They review the characteristics of...

Students examine molecules and the changes in energy of a system.  For this energy systems lesson students complete a lab activity and describe changes of state.

In this physical and chemical properties activity, students read a 2 page article, identify 10 changes as physical or chemical characteristics and decide whether 3 combination of objects are chemical or physical mixtures and explain why.

Eighth graders examine the development of the different temperature scales. They experiment with hot and cold temperatures.

Ninth graders participate in classroom discussions, demonstrations and hands-on laboratory activities about pure substances and mixtures with a focus on common household materials. They investigate: What is a pure substance? What is a...

Students discuss and experiment with the phases of water.  In this phases of matter lesson plan, students recognize the different states of matter.  Students measure and record changes and understand when the state changes.

First graders investigate the various forms of water. They discuss the properties of water. They discover examples of water's various states and locate other solids, liquids, and gases in their homes.

For this chemistry worksheet, 11th graders take a states of matter quiz by matching 10 terms to their definitions, decide if 10 statements are true or false, and answer 2 fill in the blank questions.

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...

In this cold quiz worksheet, students complete a six question multiple choice on-line interactive quiz about cold places and cold weather.

In this heat worksheet, students determine the heat gained or lost when matter changes phases. Students review the energy flow through ecosystems by comparing trophic levels and food webs. This worksheet has 10 fill in the blank, 5 short...

In this carbon dating worksheet, students write and illustrate a comic strip describing the entire process of C-14 dating. Then students complete 6 short answer and 2 fill in the blank questions.

First graders investigate the different water formations by conducting an experiment.  In this water properties lesson, 1st graders examine jars filled with ice, rain water, air and snow in their class.  Students predict what...

Students explore the effects that extreme temperatures have on the material properties of solids. They investigate the properties of a material whose state depends on extreme temperatures and witness how it interacts with room...

Pupils are read the story "Snowballs" and discuss what the conditions must be for it to snow. They make snowmen out of snow when it snows outside. They discover what happens to their snowmen when they take them inside.

In this general science learning exercise, students find 32 science words reviewing states of matter and types of substances. Students may self correct by selecting the link at the bottom of the page.

First graders investigate the changing states of water.

There are some amazing ways species evolve to survive. From large ears to sneezing salt, learners read about these interesting adaptations in an interactive lesson. Great to supplement an in-class lesson, it also works well as a remote...
