GIZMOS Student Exploration Growing Plants

Exam (elaborations) GIZMOS Student Exploration Growing Plants Student Exploration: Growing Plants Directions: Go to Explore learning and Launch the Growing Plants Gizmo. Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: compost, fertilizer, mass, seed, soil, variable Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. What do you think plants need to grow and stay healthy? Plants need light, water, nutrients, air, and space to grow and stay healthy. 2. Soil is a combination of tiny rock fragments and decayed plant materials. How do you think soil helps a plant? Soil provides nutrients and support for the plant to grow. Also the water gets stored in the solid to then get to the plants roots. Gizmo Warm-up: Grow the Biggest Plant! 1. In the Gizmo set up the three pots however you like: ● Choose a seed to drag into each pot. ● Click on the light bulbs to turn them on or off. ● Drag the Water slider up or down to set the amount of water each plant will get. ● If you like, drag fertilizer or compost into a pot. ● When the pots are ready, click Play ( ) and wait for the simulation to end. 2. How tall was your tallest plant? My tallest plant was 43.8cm. 3. Click Reset ( ) and Clear pots. Run a few more trials to grow the tallest plants you can. What conditions led to the tallest plant? The conditions that led to the tallest plant were having enough light and water. Reproduction for educational use only.

Question: Do seeds need water to grow? 1. Form hypothesis: Do you think seeds need water to start growing? Explain why or why not. I do think seeds need water to start growing because based on the results from the trials on the warm-up, the plant that had less water usually grows less. 2. Set up Gizmo: In the Gizmo, set up the three pots like this: ● Pot A: Bean seed, two lights on, 0 mL water per day ● Pot B: Bean seed, two lights on, 50 mL water per day ● Pot C: Bean seed, two lights on, 100 mL water per day 3. Experiment: Click Play to start. When the simulation is done, observe the plants. 4. Collect data: Fill in the data table below with the height and mass of each plant on day 50. (The mass of a plant is the amount of matter in the plant. It is related to how heavy it is.) In the last column describe what each plant looks like. Pot Water/day (mL) Height (cm) Mass (g) Appearance A 0ml 0.0cm 0.0g There was nothing B 50ml 47.7cm 4.7g The plant looked pretty healthy and green. C 100ml 51.9cm 4.9g The plant looked tall and green, overall it looked healthy. 5. Draw conclusions: Do seeds need water to grow? (Was your hypothesis
