8. Retake Requirements Review the explanations you wrote down today.
Complete the online tutorial at iew/126096
Complete and bring the required additional targeted practice assignment with you when you come in to retake the assignment.

9. Practice: Types of Investigations Game
Lesson Objective: I can identify the types of research questions that each scientific investigation would best answer.
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.

10. 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.

11. Controlled Experiment
Game Answer Key: In your science notebook, copy at least 2 questions for each type of study.
Observational Study
Comparative Study
Controlled Experiment
