Research and Describe a Population Change
Explore topics! Describe a population and determine what may be causing a change.
Do you want to study:
- a land animal
- a bird
- an insect
- a plant
- marine life
- something else?
Visit the Library Database and Websites tabs above to explore topics and learn about a population change.
Data & Scientific Principles
Research and provide data as evidence to support the population change.
|The fisherman observed the trout had bloody wounds on the side of its body.
(Think five senses: taste, smell, touch, hear, sight)
|The Dioxin in the Great Lakes increased by 70 parts per trillion between 1930 and 1950.
Which scientific principles listed below apply to your population change?
- Food contains substances like protein, fat, and starch.
- Food provides energy and building materials for organisms.
- Animals get their energy and building materials from eating other animals and plants. Plants make their energy and building materials from light and water.
- Organisms in a food web are related through producer/consumer, predator/prey, and parasite/host relationships. Because of these relationships, one population affects others through direct and indirect interactions.
- Organisms that live in an ecosystem are affected by other organisms and by the abiotic factors in that ecosystem.
- All organisms in a food web are interconnected.
- All plants and animals have special structures that perform the functions necessary for reproduction and eating.
- Organisms in an ecosystem compete for limited resources like space, food, and water. When there is not enough of a resources individuals in the population die.
Develop Specific Questions
Develop research questions to answer.
Here are some examples:
- What has changed where this organism lives?
- Is there another organism doing something to affect this organism?
- What happened to the climate or food supply?
- Did something happen to the organism's offspring?
- What are other direct or indirect relationships affecting or affected by the population change?
What are YOUR questions?
Provide a Claim and Continue Research
Provide a claim with evidence to support your claim. You should also provide answers to your research questions.
Example of a claim:
There is a decrease in food in the water for an organism.
Example of evidence:
The Dioxin in the Great Lakes increased by 70 parts per trillion between 1930 and 1950.
