__________________________________________________________________________________________________________________________________________________________________________________________________________________________________Purpose: To practice data collection and analysis, to make observations on a familiar system undergoing change, and to determine which food provides more energy.Essential Question: Which food would you want to stockpile in order to be prepared for a zombie apocalypse?Hypothesis: Using what you know about the problem and the scientific concept of the lab, state a hypothesis, your best estimation of the answer to the essential question. Then describe the reasoning that led you to your hypothesis, using what you know about the scientific concept as a basis for your reasoning. Your hypothesis should be an if/then/because statement.____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Materials available for you to use… if you don’t see something that you want to use, ask the teacher if it’s available!- Safety Goggles - Food Samples - Matches- Stop Watch - Piece of foil - Thermometer- Electronic Scale - Beaker of water - Ruler- Ring Stand - 2 Rings - Wire Gauze Square- Paperclip - Soda CanExperiment and Data Collection:Briefly describe an Experiment that you can do to test your hypothesis. Don’t give all the details here, but explain how you will test the hypothesis. Include what variable you will change, what variable(s) you will measure, what control(s) you will need, and how many trials you will do.___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
