Students may wish to explore how changes in solids and liquids impact them, their families, the community and the environment.

Students could try mixing different types of liquids to look for evidence of physical or chemical changes.

It is highly recommended that students follow up this lesson with the Mystery Powders lesson.

To help students keep track of the experiment over the course of the week, use the Physical and Chemical Change Experiments Predict and Observe Chart reproducible to monitor the changes day by day.

Egg (or chicken bone) in vinegar (gas produced).Baking soda (or powder) and vinegar (gas produced)Īlternatively or in addition to, you could choose a physical and a chemical change experiment that requires more than one class period to complete with students.Chemical hand-warmers (temperature change).Roasting marshmallows (colour change, odour).Rusting steel wool (colour change, temperature change).Cabbage juice with acids and bases (colour change).Cut a piece of paper or a different material into smaller pieces.Note: Crosscheck for student allergies (egg, dairy, fruit, etc.) before choosing a demonstration. These demonstrations are quick and can be conducted within a class period. You could choose one demonstration from each of the two categories listed below. Model some physical and chemical changes to students. Pause the slideshow to describe the images using the alt text for students who are blind or have low vision.Īction: Exploring Physical and Chemical Changes (30-45 min.) Instructions

Click the arrow beside the story title and select “Edit Story Stylesheet”. Once you have finished the layout and each path has an ending you can change the appearance of your story. Keeping all this in mind, what do you think the law of conservation of mass means?Īccording to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.Let’s go back and look at how many people are on each side in the previous reactions.

How many people (elements) are on both sides?.Have you noticed any consistencies yet?Īgain show only reactants, have students brainstorm what they predict will be the product before revealing it. Are there any similarities?įor this equation, start by only showing the reactants, and ask students to brainstorm what they predict what the product is. Modify the following equations as needed to match the level of your class.įor this reaction you need one calcium and carbon element on each side and three oxygen elements on each side.Īt this point ask students what they have noticed about these reactions. The goal of this activity is for students to notice that you need the same number of people on each side of the equation (which represents conservation of mass and a balanced equation). Have reactants stand on one side of the room and products on the other. Students will form “bonds” by linking arms. This activity involves the students pretending to be elements (holding cards to represent their element) and rearranging themselves to show the reaction.

In order to understand how chemical reactions work, students must first understand how chemical equations work and how to balance them.
