In this physics activity, learners build their own rockets out of film canisters and construction paper. Learners discover how a chemical reaction (from a mix of water and Alka-Seltzer) creates gas pressure to propel the craft. The activity explores the three states of matter and Newtonäóťs Laws of Motion.

In this "Sid the Science Kid" activity, learners make applesauce to explore irreversible change. Learners compare and contrast apples that have been changed by heat with apples that haven't been changed. This activity includes a "Sid the Science Kid" video showing how to conduct the investigation. Safety note: adult supervision required.

This open-ended art project allows learners to create their own colorful ice sculpture by using rock salt and food coloring on a solid block of ice. The entire activity is like a mini-science lesson because it teaches learners the physical reaction of salt on ice.

In this activity about states of matter, learners get to witness firsthand the awesome power of air pressure. They watch as an ordinary soda can is crushed by invisible forces. This activity is only to be done with adult supervision, as it involves very hot water.

In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice. This experiment illustrates how carbon dioxide can be stored in a substance. Learners compare and contrast the results to determine if liquid carbonation is an effective method for carbon sequestration. Safety note: this activity involves dry ice; please follow recommended guidelines.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials. Learners group together and link arms or hold hands to form chemical bonds and act out the processes of photosynthesis and respiration. Use this activity to introduce the carbon cycle and follow this activity with two associated activities from the same resource.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause global warming. This activity is the second in a series of three activities that introduce learners to the carbon cycle (see related sources), although it is not mandatory that all three activities are completed as a set.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon. Learners role play as miners, power plant operators, car drivers, and home owners in a city. Learners will act out how each member of society contributes to the carbon cycle and then create a classroom mural depicting the path of carbon. Learners can reflect on this process as well as brainstorm ways to lower their carbon footprints. This activity is the third in a series of three activities that introduce learners to the carbon cycle (see related sources), although it is not mandatory that all three activities are completed as a set.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth! They learn about the different ingredients a cloud needs in order to form, and then duplicate the process that usually takes place thousands of feet above their heads.

In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails. This activity introduces learners to the structure of comets and the interactions between comets and our Sun.

In this activity, learners investigate and compare the rate of drying in different conditions. Learners place wet dish cloths in front of a fan, on a flat surface inside the room, in a box with a lid, and outside on the grass or in the sun by a window and record the dampness on a chart every ten minutes. Learners discover that wind can impact the speed of water evaporation. This activity can also be used to introduce learners to the scientific method.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions. Learners can experiment by modifying their rocket designs (shapes) or "fuel packets" (baking soda).

This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or physical change: mixing vinegar and metals (chemical), baking soda and vinegar (chemical), antacid tablets and water (chemical), cabbage juice indicator and acids and bases (chemical), sodium polyacrylate and water (physical), and cornstarch and water (physical). Connections are drawn to everyday chemical reactions in the "Changes in Everyday Life" handout.

In this activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass. The salt allows the temperature of the water to drop below the normal freezing point, so that water vapor in the air turns directly into solid ice on the surface of the glass.

In this "Sid the Science Kid" activity, learners observe reversible change while thinking about ways to make ice melt. Learners freeze a piece of fruit in an ice cube and then explore ways to get the fruit out of the ice (using warm water to melt the ice, microwaving the fruit cubes, or just waiting). After, learners can enjoy their healthy snack! This activity includes a "Sid the Science Kid" video showing how to conduct the investigation.

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen. This hands-on experiment explores the process of electrolysis, and shows how graphite in a pencil works as an electrical conductor.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink. Learners work in teams of at least two to extract, collect, and measure gas (volume) from a can or bottle of cola. Learners can also compare the volume of gas to the mass loss and determine the molarity of the CO2 in the cola.

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix. In chemistry, this mixture is known as an emulsion. Substances like egg yolks that assist with emulsification are called emulsifiers.

In this activity, learners discover that sand is the major ingredient in glass. They carry out a guided investigation involving chocolate to see what happens when heat is applied to a material that appears solid at room temperature. They learn that glass has special physical properties that allow it to be formed into many different and beautiful objects. At the end, learners can eat the outcomes of the investigation! This activity is featured on pp.32-34 of the "Fireworks of Glass: The Art of Dale Chihuly" unit of study for grades 3-5.
