7. HW Review: What type of Investigation?
Observational, because she is simply making observations about the tissue of the celery and not comparing it to anything else.
Comparative, because he is comparing the number of stomata on a hibiscus leaf versus an ivy leaf.
Experimental, because he is changing the temperature of the potatoes and measuring the effects on enzyme activity. He also has a control group
Experimental, because she is changing the pH levels and measuring if there is an effect on bean growth. She also has a control group.
Comparative, because she is comparing how the worm moves under different conditions. (Yes, this is different from what I told you previously. I apologize for my mistake!)
Observational, because he is simply making observations about the traits of each food sample, in this case, whether it had starch.

8. Practice: Types of Investigations Game
In assigned groups of 3-4, each group will be given a bag of paper.
First, take the pieces of paper that say “Observational Study”, “Comparative Study”, and “Controlled Experiment” and place them on your desk.
Put the rest of the paper back into the bag.
Wait quietly until all groups are ready.

9. Instructions
You will be playing a game against one another. Groups will attempt to place the statements under the correct headings. The first group that can correctly place the statements wins.
When a group is done, 1 member will write their group number on the Smart board.
Mr. Santos will walk around to check group answers in the order listed on the board.
If a group is not completely correct, one member of the group must erase their number from the board and the group will fix their answers. When the group believes their answers are corrected, one member will re-write their number at the end of the list.
The game will continue until the top 3 groups are identified or until time runs out.
