Brochure: Making a Thriving Garden We’re going to start an activity today that you’ll have a fair amount of time to work on this week. We’ve learned a lot about plants. As such, I want you to start creating a brochure on how to make a thriving garden with an increasing population of plants. Your brochure will have 3 pages: - Asexual Plant Reproduction - Sexual Reproduction: Flowers - Sexual Reproduction: Seeds Your job today is to work on just the first page. Each page should include specific directions.
