1) The document discusses creating a chemical compound by making homemade ice cream. 2) A chemical compound is formed when two or more elements are chemically joined together, unlike a mixture where substances are mixed but not joined. 3) To make the ice cream, students combine milk, sugar, creamer and vanilla in a bag, then shake the bag inside a separate bag filled with ice and salt to cause the ingredients to freeze into a compound of ice cream.

2. Objective: 1) To create a compound made up of a combination of materials.

3. Essential Question: What is a chemical compound?

4. We will explore this question in our experiment today.

5. Compounds A compound is a substance formed when two or more elements are chemically joined.

6. Compounds are different from mixtures. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of.

7. Mixtures are two or more substances that are mixed together but not chemically joined. A good example of a mixture is a salad. There are tomatoes, lettuce, cucumbers, and salad dressing all mixed together. Mixtures

8. No chemical reactions occur between the vegetables and the dressing. You can separate each of the vegetables from each other. A mixture of salad

9. Let’s create a chemical compound… ice cream! Materials for each student: 1 gallon size Ziploc baggie 1 quart size Ziploc baggie 1 cup of milk ¼ cup of sugar 1/8 cup of coffee creamer 1 tsp. of vanilla flavoring 2-3 cups of ice ½ cup of rock salt

10. What in the world are we doing? The gallon bag will act as a “freezer.” Only non-edible items go in this bag. The quart bag is your “dish.” All the edible ingredients go in this bag. Be very careful to keep the quart bag sealed tight while making your ice cream. xxxxxxxxxxxxx xxxxxxxxxxxxxxxxx

11. OK, let’s Get Shaking! Procedures: 1. Place the milk, sugar, creamer, and vanilla in the quart Ziploc bag. 2. Put the ice and rock salt into the gallon Ziploc bag.

12. Procedures: (continued) 3. Carefully seal the quart Ziploc bag and place into the gallon Ziploc bag. 4. Seal the gallon Ziploc bag and Shake, Shake, Shake!!

13. Procedures: (continued) 5. In approximately 15 minutes, unseal the bags and check to see if the ice cream is ready. 6. When removing the quart bag, be careful not to let any of the salty water into the ice cream. 7. Grab a spoon and enjoy your delicious work!!!

14. Clean Up! Clean up and place all waste in the garbage can on your way out the door.

15. The Write Stuff Record your responses to these questions in a paragraph in your science notebook: A. What chemicals did you combine? B. Did you create a physical change? C. Did you create a chemical change? D. What is a compound?

16. Now, Let’s Get Graphic! Draw a diagram in your Science notebook of an atom. Remember, all matter is composed of atoms. The substances you combined to create ice cream are all made up of atoms.
