Page history last edited by Hassan Wilson 14 years, 11 months ago

Name:

Sponge Capsule Exploration

1. What observation did the class make about sponge capsules today?

2. What hypothesis did the class agree on? Fill in the blank.

“_____________________________________ affects _____________________________________.”

3. How will you test this hypothesis? (Think of an experiment.)

4. What materials will you need to do this test?

5. In this test, are you treating all of the capsules exactly the same? If not, then how are you treating the capsules differently?

6. In this test, what things should be the same about your capsules and the materials that you use? Why?

7. What data are you measuring at the end of test?

8. How will you know if the class’s original hypothesis is correct?

9. What obstacles/problems do you foresee with your test?

10. What could you do differently in a future test in order to have even more confidence that your results (& conclusions) are accurate?

NAME OF GROUP MEMBERS:

Sponge Capsule Investigation

Your group will design and carry out an experiment to find out if following hypothesis is true: Temperature of water affects the speed of sponge capsule emergence.

While your group may wish to bring in materials, I will provide the following items: four sponge capsules (or 1 per person in your group), thermometers, tap water, glassware (like beakers, cylinders, test tubes), hotplates, styrofoam cups, coffee stirrers, lunch tray, markers, masking tape and stop watches.

Tasks

1. State a reasonable prediction assuming the above hypothesis is false.

2. Briefly explain how you would test this prediction during an experiment in no more than three sentences.

3. Fill in blank procedure & materials list form.

4. In detail, list the steps of your experiment in order.

5. What data will you need to collect?

Due Dates for tasks 6-10 will be announced shortly.

6. Once finished, show this sheet to Mr. Wilson in order to get approval. Make the appropriate revisions until you have received approval.

7. Fill in experiment design template sheet for this investigation.

8. Gather materials & conduct experiment.

9. Read lab report guidelines from course moodle site.

10. Write lab report individually.
