Lab #5: Invertebrate Survey
Problem: What is the population of invertebrates in a location near you?
Hypothesis: Write in an if…then…format
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: _________

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?
