Population Study
An experiment in which the observer collects data over time for one population in an ecosystem
Observational study
An experiment in which the observer collects data over time without interacting with the area of study
Controlled Experiment

What does the population of milkweed bugs need to survive in a classroom?
Water, shelter, food, air, female/male, sunflower seeds.
How do milkweed bugs reproduce and grow?
Male/female, mating, laying eggs
What is the relationship between individuals, populations, communities, and abiotic factors in an ecosystem?
more than one individual is a population. More than one population is a community. And a community and abiotic factors make up an ecosystem.
How is the milkweed bug habitat similar to and different from Jane Goodall population study?
They were both making observation, ours is a controlled set up, Jane Goodalls wasn’t not in a controlled set up.
