BIOLOGY– Plant Growth Experiment Warm-Up: What do plants need to survive? Today: Introduction to Plant Growth Experiment Research

What do plants need to survive? Sunlight – make food through photosynthesis Gas Exchange (CO 2 and O 2) Water and Minerals PHOTOSYNTHESIS 6 CO 2 + 6 H 2 O + light → C 6 H 12 O 6 + 6 O 2 Carbon dioxide + Water + Light energy → Glucose + Oxygen *Plants are AUTOTROPHS = make their own food

What other factors influence plant growth? Brainstorm

Plant Growth Experiment Purpose: Describe the characteristics and growth of a specific species of plant. Marigold (Tagetes patula) Design an experiment to test how an experimental variable will affect plant growth. Directions: Each Group will have 4 plants. Half of these are controls and the others will be the experimental. You will be responsible for taking care of your own plants.

Plant Growth Experiment 1. Conduct background research about plant growth. You will research How your chosen variable affects plant growth. 2. 3. 4. 5. Develop a question about how a particular treatment will affect plant growth. Develop a hypothesis based on research. List the materials you will use for this experiment. Design an experiment to answer that question.

Other 1 plant per cell No sugar or salt No mixtures If they die, you will need to start over Remember: YOU are now responsible for taking care of your own plants.
