PLEASE HELP WITH THIS WILL GIVE ANYTHING YOU WANT INCLUDING MONEY AND BRAINLIEST JUST GIVE ME THE ANSWERS I WILL PAYPAL OR GIVE YOU $25 AND GIVE YOU LOTS OF POINTS AND BRAINLIEST HERE IT IS READ IT CAREFULLY THIS IS FOR SCIENCE: Student Exploration: Growing Plants 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?





2. Soil is a combination of tiny rock fragments and decayed plant materials. How do you think soil helps a plant?





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?

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?





Activity A: Wet and dry Get the Gizmo ready: · Click Reset. · Click Clear pots.

Question: Do seeds need water to grow?

1. Form hypothesis: Do you think seeds need water to start growing? Explain why or why not.





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

B

C

5. Draw conclusions: Do seeds need water to grow? (Was your hypothesis correct?)



6. Revise and repeat: Is more water always better? Create your own experiments to find the ideal amount of water for each kind of plant. Explain your findings below.
