Lab #5: Invertebrate Survey
Problem: What is the population of invertebrates in a location near you?
Hypothesis: Write in an if…then…format
Method:
1. Cut a piece of string that is 8 feet long so you can form a 2×2 foot square.
2. Head outside (your backyard, front yard, a park, etc) and use your string to create a square.
3. Observe and record all of the invertebrates you notice. Spend 20-30 minutes making observations. You can move things around in your square (like looking under a rock or a stick, but be sure to replace them).
Results: Create a chart similar to the one below to record your observations.
Location of observations: ______________
Time spent: _________
Invertebrate (name or description)
Location of Invertebrate (on something, under something, flying, etc)
Two observations of Invertebrate
Total Number of this type of Invertebrate
Discussion/Analysis:
1. Describe your success in finding invertebrates. Were you able to see any? A few? Lots? Why do you think you did/did not have success? If you had no success, you might try a different spot.
2. Where were most of the invertebrates found?
3. Did you notice any similarities between the invertebrates? What were some differences?
4. How many total invertebrates did you find? Do you think this a good sampling of the area? Why or why not?
Conclusion: What is the answer to the problem question? Was your hypothesis correct? Were there sources of error? What could be done differently next time? What did you learn?
