questions on front page of lab
Here’s what you need to submit:
Submit the following (in the order listed)
1. Pond Water Lab Title Page
2. Microscope review questions
3. Two practice biological drawings
4. Pre-lab research assignment
5. Observation Questions – include draft sketches
6. Two Pond Water Biological drawings
7. Conclusion Questions
After the lab: Making Connections
1. Review the field guide and brainstormed list of
plants and animals from your pre-lab research.
1.
Is there anything you would like to add to these lists based
on your pond water observations?
2. Use small Post-It notes (or other small pieces of
paper) write the names of at least 10 of the plants
and animals from the list.
3. Create a food web using the Post-It notes. Use a
large piece of construction paper to create a display.
** You may want to use a computer to determine
what each of your organisms eat.
4. Compare food webs with other groups.
5. Predict what would happen if :
• a specific organism was removed from the web due
to disease or pollution
• the population of one organism was to double
• an exotic (invasive) species was introduced to the
food web.
