lab is a special exception to the rule of ‘No food or drink in the
laboratory.’ It is extremely
important that before we use lab equipment to measure chemicals for human
consumption we make sure the equipment is clean!
Let me stress that in all other labs you MUST NOT eat or drink anything!
This lab is definitely a chemistry lab even though we are making Kool-Aid̉:
cooking and preparing foods is, when you come right down to it,
|PLAN THE EXPERIMENT|
As a group, agree upon and write out the hypothesis statement.
List the steps you need to take to test your hypothesis.
Be specific; describe exactly what you will do at each step.
Make a list of the materials that you will need to complete your
Create your data table, so that it is ready to use as your group collects
|1. Read over your entire experiment to make sure that all steps are in logical order.|
|2. Identify any constants and the variables of the experiment. Have you allowed for a control? How will the control be treated?|
|3. Do you have to run any tests more than one time?|
you finished the above steps, present your plan as a group to Ms. Brands.
No one will be allowed to do the lab until your plan is presented as a
group to Ms. Brands, and she approves the lab.
You will not receive lab equipment until your plan has been approved.
|DO THE EXPERIMENT|
Carry out the approved experiment as planned.
DO NOT CHANGE ANYTHING WITHOUT APPROVAL!!
While the experiment is going on, write down any observations that you
make, and complete the data table.
Write down the recipes for unsaturated, saturated, and supersaturated
Compare your results with those of other groups.
