Another busy day in science.

First you got your tests back from Friday — results were not as good as I had hoped, so we spent additional time going over experimental design. Remember the purpose of this is for you to plan your experiment in enough detail that someone else could take your plan and conduct your experiment, in the same way you would, and get the same results.

To do good science, others must be able to duplicate our experiments. This is the only way new theories are “proven”. On one of your future experiments you’ll actually do that, trade experimental designs with another table or class and see if they can duplicate your experiment.

Last you spent a little time testing your experimental design so tomorrow you’ll be “ready to roll”. There will be no bell work, instead start the data collection portion of your lab right away.

P.S. PARENTS — Grade slips were sent home with students today. Please be sure to review and sign them. Students, return them by Friday of this week.
