testing plant growth
- Nutrients in the soil (or water) are used by plants and other organisms.
- Observe that plants use the nutrients in the soil to aid in growth.
- Plan and conduct an experiment and make predictions about how soil nutrients will affect plant growth.
- Observe each plate of materials and write observation on the worksheet provided. Be sure to include information about the properties of the matter on the plates, including shape, size, color, etc.
- Review the matter with your teacher and whether or not each plate contains organic or inorganic matter.
- Complete the Growing Plants: Data and Prediction sheet provided.
- Follow the directions on the Growing Plants: Procedure Sheet.
- Open your Ecosystem GoogleDoc.
- Scroll to the bottom of your document and hit enter twice.
- Type "Lesson 5-Testing Plant Growth-Session 2"
- Discuss the following questions with your table group and then answer the questions in your own words.
- What variable are you testing?
- What is your prediction?
- Which parts of the set up are exactly the same?
- Which parts of the set-up are different?
- Why do you need a planting cup with an inorganic material in addition to the cup with organic material to test differences in plant growth?
- What data is your group collecting to serve as evidence to show how plants grow in organic planting material versus inorganic planting material?
- Where will the plants get their energy for growth?
- Where will the plants get most of their matter for growth?
- Where will the plants get other nutrients?
- How are your planting cups like an ecosystem?
- What are the components of the planting cups ecosystem?
- What are some ways that the components of the ecosystem interact?
