Includes the first three lessons from the Classroom Chemistry Let's Do Science Bundle These include:
LESSON 1: OUTLINE- CRUSHING CRANBERRIES
In this traditional Cree legend with the Cree trickster Wesawkechuk, whose encounters with a bear provides some moments of “Classroom Chemistry.” This legend reinforces the oral tradition of Aboriginal people, and that traditional teaching methods were often achieved through a story. Afterwards, students will test cranberry juice, vinegar, water, and a baking soda and water solution to determine whether the liquids are acidic, basic or neutral using pH paper.
LESSON 2: OUTLINE- A DESIGN MASTERPIECE
Students will attempt to send a tin foil canoe across a pan of water. When they place some dish-washing detergent on their fingertip and dip their finger in the water the tin foil moves through the water.
LESSON 3: OUTLINE- WATER, WATER EVERYWHERE
Students will be testing various materials to make a waterproof container to help Wesawkechuk carry his bear fat.
During these activities students will students learn about the properties and interactions of some safe to handle household liquids and solids. They test a variety of materials to see what happens when things are mixed together: what dissolves, what reacts and what remains unaffected. They discover that when a solid material dissolves, it can be recovered as a crystal by evaporating the liquid. They also learn that when two materials react to form a new material, the original materials cannot be recovered. As an example of a chemical reaction, students learn to produce carbon dioxide gas and show that this gas differs from ordinary air.
After completing these 3 lessons, students will be able to:
