• All of the foods that we eat are made up of organic compounds and you can perform tests to see what each food contains.– What is an organic compound?

• Today we will be testing solutions to look at those tests and find out what organic compounds we have in each one.

Safety!Safety!• Protective eyewear must be worn at all times during this lab.

• Some of these reagents are poisonous so no food or drink is allowed in the classroom today. Keep it put away.

• Wash your hands after you complete each station. Even if you think you don’t have anything on your hands, it’s better safe than sorry.

• You will have a data chart for each test, 4 total.

• These will be used to make conclusions at the end of the lab and will be graded.

• Take you time, be careful and deliberate

• WASH your test tubes between each test and at the end of the period

GraphingGraphing• Choose two of your tests and create a bar graph to display the numerical data you recorded. Put the solutions on the X-axis and the number (0-4) on the Y-axis.

ConclusionConclusion• Identify which solution you think is the sample for each of the tests and which is the control. Discuss what you saw for the positive test in each of the four experiments.

• Identify weaknesses or errors in the experiment

• What would you do in the future to test this differently?

This should be at least two paragraphs.
