Students continued their learning about density by working through the ChemCatalyst starter activity included in the Lesson 51 PowerPoint and then working in small groups to complete the Lesson 51 Worksheet. Textbook questions 1-9 were assigned as homework.
In support of the House A Support Day, we elected to use class time today to complete the following work:
- Yellowstone Trophic Pyramid (pyramid + food web handout along with trophic pyramid worksheet both due today)
- Read the article titled “Interdependence Involves Limiting Factors and Carrying Capacity” on pages 650-652 of the BSCS Biology textbook. Take notes and define vocabulary in notebooks.
- A limiting factor is anything that can slow, or limit, the growth of a population.
- Biotic factors: food supply and other organisms
- Abiotic factors: space, raw materials, climate (the prevailing weather conditions in a given area through long periods of time), light
- Carrying capacity is the maximum population of a particular species that the habitat can support. It changes as environmental conditions change.
- Population density is the number of individuals in relation to the space the population occupies.
- Model photosynthesis using molecular modeling kits.
- Sunlight + H20 + CO2 –> C6H12O6 + O2
- To balance the equation, need 6 each of H20, CO2, and O2
