Unit 5, Lesson 2: Mini-Thresholds
Learning Target: I can explain how complexity increases among the mini-thresholds of life.
Class Activities:
1. The kids walked in and took out the previous lessons handout, titled, "Intro to Threshold 5". We copied the notes in the chart for Part 4: I'll type the info below, and you can fit it into the chart yourself.
Characteristics of what it means to be alive:
2. I passed out the next worksheet, titled, "Mini-Thresholds of Life." A couple hundred years ago, people explained life as logically as they could. But they lacked the tools or knowledge to understand how life evolved. Instead they believed in spontaneous generation. Students read some quotes about spontaneous generation, then filled out the four questions on the front.
3. When they were done, they moved on to part two. This chart shows the evolution of complex life, from tiny prokaryotic bacteria to large mammals. Use the class materials to complete the table on the back.

Characteristics of what it means to be alive:
- Metabolism: Using energy from the environment. Examples are eating, breathing, and photosynthesis.
- Reproduction: Making copies of itself. Examples are sexual reproduction, pollination, and cellular division.
- Adaptation: Changing characteristics to adapt to an environment. Examples are thicker fur, changing color, etc.
- Homeostasis: Regulating conditions in order to maintain a stable state. Examples include sweating, shivering, and thirst.
