In this lesson, students will sprinkle coarse salt on a piece of ice and make observations as it melts. They will also make homemade ice cream. They will then use their observations to discuss heat energy and chemical reactions.

In this activity, students will be introduced to the concept of chemical change when they observe the chemical change that occurs between vinegar or lemon juice and heat. Students will write a secret message with vinegar/lemon juice and expose the invisible message when the paper is passed over a heat source.

In this activity, students use chemical change to create an exothermic process by making sodium acetate.

As students are learning about substances, mixtures, and solutions, they will participate in several experiments that involve chemical reactions using regular household products. Some experiments will produce gas or create something that will grow. Students will work in groups of 2-3 students to make a car move using the result of a chemical reaction from combining two or more household substances. They will present their project to the class.

In this activity, students complete a series of simple tests using five powders to explore chemical and physical properties, changes, and reactions.

Second part to the C2 Superlesson for ROV's from Kim Stokes and Ben Wells, Siuslaw Elementary School.

In this lesson, students explore the concept that mass is conserved during physical and chemical changes by experimenting. Students take initial masses, make predictions, and find final masses of physical changes such as ice changing to water, and the mass of aluminum foil in the form of a ball versus flat. Students work in small groups and use a balance to take the masses.

In this activity, students will differentiate physical and chemical changes by doing an experiment. They will also learn what an exothermic reaction is.

In this lesson, students identify the natural elements that have helped the Statue of Liberty change color over time and describe how the oxidation process can impact metals like copper. Students will also interpret whether the Statue of Liberty will hold as much cultural significance today had the copper not oxidized.

In the introductory unit activity, students are presented with a variety of snack foods, make observations about each, and discuss the properties of each. They will then mix them all together, observe, and then discuss whether the properties of the foods have changed. They will then predict how their properties might change if water is added or if they are heated in a microwave and make observations as these experiments are done.

This activity is intended to introduce students to the difference between physical and chemical changes in matter. Students will investigate the interactions of antacid tablets, water, vinegar, and bromphenol blue indicator to investigate changes in matter; observations will be recorded on a provided note sheet. Several ideas for assessment are also included.

In this activity, students will predict what will happen when two solutions are combined, and make observations about the properties of the new substance. Note: The teacher prepares the solution prior to the activity.

Students will perform simple experiments to investigate how matter can be changed from one form to another. Students will mix various solids and liquids and make observations about the results.

In this activity, students examine properties of substances. They will work in teams to identify unknown substances.
