11.7.12 Foil LabOBJ: We will identify chemical changes using evidence from our lab.

S Is this chemical change or a physical change. JUSTIFY your answer.

Title: Foil LabPurpose: We will identify if a chemical change has occurred when we combined foil and easy off.Research: 1. What is a chemical property? 2. What is a physical property?3. What evidence is there if a chemical

change has occurred?

P

Hypothesis: If we combined foil and easy off then we will see a __________ change, because we will see _________ happen.

P

Procedures: 1. Record the physical properties you can observe about easy off and foil

A

Foil Easy off

Physical properties observation before the reaction

Observation during the reaction

Physical properties after the reaction

Read your data chart to your partner.

Write down 3 things you can learn from the data that your lab partner read to you.

Use Complete sentences

C

Look back at your hypothesis. EXPLAIN if your hypothesis is valid or invalid.Ex: My hypothesis is ______ because when we combined foil and easy-off a ___________ occurs, because ___________, ____________, __________, and _____________are evidence of a ______ change.

P- work with a partner to sort the cards. Then create a T-chart and list the items where they belong. A- Title: Balloon and Flask LABPurpose: Is it possible to use chemistry to inflate a balloon? Research: 1. The production of gas is evidence of _______

changeMaterials: baking soda, vinegar, balloon, flask, graduated cylinders, funnel, safety goggles

Procedures:1. Measure 40mL of vinegar and pour it into the

flask2. Measure 15 mL of baking soda. 3. Use the funnel to pour the baking soda into

the balloon4. Have one person hold the balloon while the

other person stretches the balloon over the flask.

5. Tip the balloon over and record your observation.

• C- Explain how you were able to inflate the balloon using chemistry. E- What type of reaction did you create today. How do you know?
