1. CLE 3231.Inq.2 Design and conduct scientific investigations to explore new phenomena, verify previous results, test how well a theory predicts, and compare opposing theories.

2. There are 3 roles for each group 1) Manager: reads out directions to group, asks teacher questions, and keeps group on task. 2) Recorder: records and organizes data into a data table. 3) Technician: collects and returns lab equipment and is responsible for any damage. CLE 3231.Inq.2 Design and conduct scientific investigations to explore new phenomena, verify previous results, test how well a theory predicts, and compare opposing theories.

3. Groups  Your group role will be randomly selected for each lab.  You may not change roles during the lab.  You may not disturb other groups. This includes walking over to or talking to other groups.  Each person in the group is responsible for turning in their own lab write-up. CLE 3231.Inq.2 Design and conduct scientific investigations to explore new phenomena, verify previous results, test how well a theory predicts, and compare opposing theories.

4. Wednesday, August 17, 2011 CLE 3231.Inq.2 Design and conduct scientific investigations to explore new phenomena, verify previous results, test how well a theory predicts, and compare opposing theories.

5. Observation  Your subject for this week’s investigation: Spend the next two minutes testing the poppers, learning how they work, and deciding what kind of experiment you might want to do with them. CLE 3231.Inq.2 Design and conduct scientific investigations to explore new phenomena, verify previous results, test how well a theory predicts, and compare opposing theories.

6. Postulate 1. Decide what qualities you wish to investigate about the poppers. These should be things you can easily measure. (ex: height, diameter, time, surface, color) - How _________ affects _________. 2. Decide what variables you must control (keep the same) in order to obtain repeatable results. (ex: type of popper, surface, the same popper) 3. Decide on a procedure for investigating your question about the poppers. CLE 3231.Inq.2 Design and conduct scientific investigations to explore new phenomena, verify previous results, test how well a theory predicts, and compare opposing theories.

7. Objective example  Does covering the hole at the top of the popper affect how high it jumps? Hypothesis example  I believe that covering the hole on top of the popper will cause it to not jump as high. CLE 3231.Inq.2 Design and conduct scientific investigations to explore new phenomena, verify previous results, test how well a theory predicts, and compare opposing theories.

8. Procedure example 1. Collect 1 popper, tape, and a meter stick. 2. Have one person in the group hold the meter stick vertically on the lab table. 3. Another person in the group will turn the uncovered popper inside out and place on the lab table. 4. The 3 rd person in the group will watch how high the popper jumps on the meter stick. 5. Record this data in your data table. Repeat jump 2 more times. 6. Repeat steps 2-5 for a tape covered popper. CLE 3231.Inq.2 Design and conduct scientific investigations to explore new phenomena, verify previous results, test how well a theory predicts, and compare opposing theories.

10. Conclusions Example  When the hole on the popper was uncovered it jumped higher. CLE 3231.Inq.2 Design and conduct scientific investigations to explore new phenomena, verify previous results, test how well a theory predicts, and compare opposing theories.

11. Investigate  You must get your procedure approved by your teacher before you can begin your experiment!!!!  Your lab write-up must include:  group member names and roles  title  objective  hypothesis  procedure  data table  conclusion CLE 3231.Inq.2 Design and conduct scientific investigations to explore new phenomena, verify previous results, test how well a theory predicts, and compare opposing theories.
