Hey kids, sorry I can't be at school today. Please be on your best behavior for the substitute - I want our guest to know how awesome you all are! (-:
Today you may either continue to work on using the digestive system quiz to improve your Prezi, or work on designing your scientific investigation. If you need a copy of the quiz, there are piles of quizzes and keys on the long table in the lab. Please don't take the last copy of anything - get extra copies made if we are running low.
If you have grades to submit, wait until tomorrow and we can record them together.
If you are working on your experiment, here are some important reminders to keep in mind:
The problem is a question your experiment will answer. It is stated in the form, "How does ______ affect ____?" For example, how does foot positioning affect the distance a batter can hit a baseball?
The independent variable is the variable you will change in the experiment to find out what effect it will have. For example, foot positioning.
The dependent variable is the variable you will measure in your collection of data. For example, distance the ball travels.
The hypothesis is stated as an "if...then..." statement. If (give your reasoning), then (make a prediction).
Write your experiment in your prezi, or in Word, and then upload it to the prezi.
The steps of the scientific method are:
I. Problem
II. Hypothesis
III. Materials
IV. Procedure
V. Data and Analysis
You must have these steps completed AND APPROVED BY ME before you can even think about starting to conduct your experiment. Don't even ask the sub. The answer is no. Work on something else if you are done with this step.
