in Science Inquiry
Engage youth to:
Plan & conduct investigations
Use appropriate tools & techniques to gather data
Think critically about relationships between evidence & explanations
Communicate and share what they learn
Youth are given a problem to solve, a method for solving the problem, and necessary materials, but not the expected outcomes.
Youth figure out a method for solving a given problem.
Youth find a problem (or question)
and figure out a method to investigate solutions.
Example: “Butterflies start laying eggs in spring when the weather gets warm. I have observed Black Swallowtails laying eggs on several different plants (parsley, fennel and dill).
I wonder if the butterflies prefer one plant species?
What materials will I need to find out if they prefer a plant species?
How will I know when eggs are laid on a plant?
Materials I will need:
3 large pots or planters & potting soil (or garden space)
Black Swallowtail host plants (dill, parsley & fennel)
3 Nectar plants of the same
Watering can or hose
Plant dill and nectar plant in one pot
Plant parsley and nectar plant in another pot
Plant fennel and nectar plant in the third pot
Design your investigation
I observed more caterpillars on the dill plant at school. Therefore, I think Black Swallowtails will lay more eggs on dill plant than on the other plants in my garden.
I plan to examine the leaves of the three host plants (parsley, fennel and dill) in my garden every afternoon for two months to see when eggs are laid on the plants and if one plant has more eggs than the others. I will check that there are no eggs on the plants when I start, then I will count and record the number of new eggs I see each day.
Gather and analyze data
I recorded the number of eggs laid each day for two months.
I counted 12 eggs on the dill plant on day 9 of my study. On day 11, I counted 5 more eggs on the dill and 4 eggs on the fennel. On day 17, I counted 8 more eggs on the fennel and 14 eggs on the parsley. On day 27, I counted 7 eggs on the dill plant even though there were very few leaves left.
Interpret your evidence
Based upon what I observed, I think that Black Swallowtails prefer dill as a larval host plant.
