Pond Water Lab

During the Lab…

Obtain pond water sample from side of classTry to get water from sides or near

bottomUse a small dropKeep plastic pipettes organized! (Don’t

want to cross contaminate) Observe pond water under microscope. Use

field guide to locate specimensComplete biological drawing of specimen

(rough & good copy) Calculate actual size of specimenComplete observations and conclusions

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 Page2.Microscope review questions3.Two practice biological drawings4.Pre-lab research assignment5.Observation Questions – include draft

sketches 6.Two Pond Water Biological drawings7.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.
