In this lesson, students will design and create terrariums to study the growth of corn and legume plants. They will learn about genetic biodiversity and test for photosynthesis and nitrogen fixation in a series of labs.

Description: Planting Corn and Legumes: Later in this unit students will examine genetic biodiversity and test for photosynthesis using corn plants and test for nitrogen fixation using legumes in a series of labs. This lesson is focused around setting up the terrariums for the plants. Goals: Design a terrarium for plant study.
Objectives: Day 0 Design a terrarium for growing corn and legume plants.
Warm-Up Q = • Read instructions and come up with a design for your terrariums. A = • none
Designing your Terrarium • You will be designing terrariums and keeping track of the growth of your corn and legume plants you plant. • While designing your terrarium bottles consider the following: • Ease of accessing the plants • How will the plants gain access to water (group watering as needed, water well and wick, etc.) • You will have access to recommendations and ideas from www.BottleBiology.org
Unit Group • Groups will be working on various assignments through this unit – mainly on labs and maintaining your plants. In your group: • Determine which design your group will use. • Develop a list of materials and steps to create this terrarium. • After getting instructor approval gather materials and begin construction of terrarium.
Planting • Now that you have designed your terrariums you need to add your plants, soil and water. • The design of your terrarium or “AquaTerra” will determine how water is added. • To plant your corn and legumes you will need to: • Add soil (at least 7-10cm) • Use you thumb to make a about 2cm depression in the soil • Place a seed in the depression and cover with soil • Add some water to the soil to begin germination. • Follow instructions for clean-up and where to put your projects.
Objectives: Day 0 Make terrariums for corn and legume plants to be used later this unit.
