Animal: Praying Mantis
Seventh Grade
Life Sciences
Characteristics and Structure of Life
1. Investigate the great variety of body plans and internal structures found in multicellular organisms.
Evolutionary Theory
8. Investigate the great diversity among organisms
In the 7th grade we will also include discussions of other interactions between living organisms - parasite, herbivores, saprophytes... This is targeted at the following:
Diversity and Interdependence of Life
2. Investigate how organisms or populations may interact with one another through symbiotic relationships and how some species have become so adapted to each other that neither could survive without the other (e.g., predator-prey, parasitism, mutualism and commensalism).
3. Explain how the number of organisms an ecosystem can support depends on adequate biotic (living) resources (e.g., plants, animals) and abiotic (non-living) resources (e.g., light, water and soil).
4. Investigate how overpopulation impacts an ecosystem.
Scientific Inquiry
Doing Scientific Inquiry
Inquiry an investigation and that ideally one variable should be tested at a time; however it is not always possible to control all variables.1. Explain that variables and controls can affect the results of
Scientific Ways of Knowing
Ethical Practices
2. Describe how repetition of an experiment may reduce bias.
