This mini-unit contains the following activities:
- INTRODUCTORY NOTES PRESENTATION: (Included both PPT and Google Slides) Students view simple notes on populations as they fill in blanks on a Cloze worksheet.
- INTRODUCTORY TEXT & WORKSHEET: (Includes Google Version) Students read about the basics of populations and how they change, including limiting factors and carrying capacity. After the reading, they complete a corresponding worksheet to check for understanding.
- GRAPH CARRYING CAPACITY: Students read background information about a mink population and then graph their population data. The analysis focuses on carrying capacity.
- IDENTIFY LIMITING FACTORS: (Includes Google Version) Students are provided with information about 10 threatened or endangered species and must identify limiting factors that have affected their populations.
- ANALYZE POPULATIONS GRAPHS: (Includes Google Version) Students are provided with 9 simple population graphs and answer questions that require interpreting the graphs.
- QUIZ: This 15-question quiz assesses student understanding of changes in populations, limiting factors, and carrying capacity. Two versions are provided!
