Estimation of Population Growth by Counting Offspring: Seed Multiplication
Learners analyze a multi-seeded fruit, such as tomato, pepper, squash, watermelon, etc. They remove and count the seeds from the fruit and hypothesize/calculate the reproductive rate of that organism.

Does the Seed Matter?
Students compare the growth of watermelon from commercial seeds and those harvested from a watermelon. They complete science journals showing these comparisons based on the data they collect.

Estimation of Population Growth By Counting Offspring: Seed Multiplication
Students calculate the reproductive rate of a plant that creates multi seed fruits. They graph exponential growth and the complete a series of questions that help them infer that natural selection processes are at work in this population.

Sock Walk
First graders, after brainstorming all the ways seeds are scattered and viewing a multitude of examples of seeds, explore how seeds travel by taking a walk outdoors wearing socks over their shoes. In addition, they assess how seeds...
