|
1. Required
|
To protect the larva from wasps that lay eggs in the tiger beetle larva.
|
Observe 10 tunnels with turrets and 10 without and see which one has more parasitoids after
|
|
|
|
|
2.
Required
|
The tiger beetles construct the turrets to fit more larva in one tunnel.
|
|
|
|
|
|
3.
Extra Credit
|
The tiger beetles construct the turrets to protect the tunnel from flooding

OBSERVATION - List a puzzling observation which inspired the causal question
CAUSAL QUESTION - Write a question, that if answered, would explain the phenomenon you observed
HYPOTHESIS - What is a testable explanation for the observation? (stated as a fact)
PREDICTION - If the hypothesis is tested what specific outcome would you expect to observe? (use the key words: will, should)
CONCLUSION - Based on your results, do you support or reject your hypotheses? Explain why. Also, propose an alternative hypothesis and/or future experiments.
