2 Science Survivor Card #1 Ice Melting is a Chemical or Physical Change? You have 2 minutes to work as a team to melt 5 pieces of ice. You may use a variety of techniques to melt your ice. Each team that successfully melts their ice in in 2 minutes will be earn a science immunity tool.

3 Science Survivor Card #2 Chef Rabob poured salt and sugar into two identical containers. She forgot to label the containers. The sugar has been recalled due to contamination at the plant where it was made. So she cannot taste to see which container has salt and which has sugar. Design a science experiment using your knowledge of chemical and physical changes to determine which container has the sugar. Correct Identification will earn your team immunity.

4 Science Survivor Card #3 In front of you is an egg. How can you cause the egg to undergo a chemical change without breaking its shell? Teams that correctly identify techniques to chemically change the egg will earn immunity.

5 Science Survivor Card #4 On the table is a container with 300 mL of water. A line has been drawn on the container at the water line. What will happen to the water in the container if it is left uncovered for a week? Describe the change which took place. Correct responses will earn immunity for the team.

6 Science Survivor Card #5 On your table are vinegar, water, flour, baking soda, a balloon, bottle, and soap. How can you use some or all of these materials to inflate the balloon without using your mouth? Teams which inflate their balloons in 2 minutes or less will earn immunity.

7 Science Survivor Card #6 On the table is an index card and a pair of scissors. Can you change the index card in a way that will allow you to walk through it? You have 2 minutes to complete this task. If successful your team will earn immunity. You must also determine if this task required you to chemically or physically change the index card.

8 Science Survivor Card #7 Your teacher is holding a lighted birthday candle. Can you identify the chemical and physical changes that are taking place as the candle burns? Correct identification will earn your team immunity.

9 Science Survivor Card #8 On the table in front of you is a mixture of iron filings, sand, and sugar. How can you separate these three objects? Use the materials on your table to develop a plan to separate these materials. Teams that successfully separate or write a detailed description of how to separate the mixture will earn immunity.

10 Science Survivor Card #9 On the table in front of you are an apple, potato, and banana. Using nothing more than a paper plate and plastic knife, how can you cause the apple, potato, and banana to undergo a chemical change and a physical change? Successful teams will be able to correctly create & identify each change and earn immunity.

11 Science Survivor Card #10 In front of you are several different rocks. One of the rocks is limestone. We know that limestone reacts chemically to vinegar. Use the pipet and vinegar to correctly identify the limestone. Teams that correctly identify the limestone in 1 minute or less will earn immunity.

12 Science Survivor Card #11 The beaker in front of you contains a 50% salt and 50% water solution. Describe, complete with labeled illustrations, how you would separate the salt and water. Is a physical or chemical change required? Correct teams will earn immunity.

13 Science Survivor Card #12 Identify the following as a Chemical or Physical Change 1.Separating sand and gravel 2.Bleaching (dying) your hair 3.Squeezing oranges for juice 4.Breaking glass 5.Rusting bicycle 6.Hammering wood to make a playhouse 7.Melting butter 8.Spoiling food 9.Mowing the lawn 10.Exploding fireworks If all 10 are correctly identified your team will earn immunity.

14 Science Survivor Card #13 Which weighs more, a whole cookie or a cookie that has been broken into many pieces. Use a triple beam balance or regular balance to support your answer. What type of change has the cookie undergone? Teams with correct responses will earn immunity.

15 Science Survivor Card #14 Which of materials on the table in front can you combine inside the film canister to pop the top off the film canister? You have 2 minutes to create a successful experiment to pop the top off the film canister. Successful teams will earn immunity.

16 Team Immunity Record Members: _______________________________________ Color in the immunity lab tools for each task you complete correctly.
