### Talking to Plants Virtual lab

1. 1. Talking to Plants Virtual Lab
2. 2. State the Question: Will playing voice recordings to your houseplants make them grow bigger? Plants need water, sunlight, carbon dioxide, soil Collect Information:
3. 3. Form a Hypothesis: IF you play voice recordings to plants, THEN, they will grow bigger OR... IF you play voice recordings to plants, THEN they will grow normally.
4. 4. Test the Hypothesis: Get 2 plants Play voice recordings to plant A Don’t play recordings to plant B They get the same amount of light. They get the same amount of water. They get the same kind of soil.
5. 5. Terms you need: Control: No sound played for plants – silence Independent variables: sound played for plants- nice talk, mean talk, rock music, classical music. Dependent variables: growth of the plants – how much they grew.
6. 6. Observe: (this is part of the test/experiment) Measure the mass of each plant after 3 months of growth.
7. 7. Record and Study Data: Write down the mass of each of the plants in a data table. Graph the results to get a clear picture of which greenhouse grew the biggest plants.
8. 8. Draw a Conclusion Was your hypothesis correct? Example of a conclusion would be: My hypothesis was not correct; the data from the experiment show that playing music to plants helps them grow bigger.
9. 9. Publish your Findings: Scientists will tell other scientists about their experiments by writing in scientific journals (kind of like magazines for science nerds). Then other scientists can build off of what has already been done. Or they can do the same experiment to double check their friend’s work to see if their results are really true.
10. 10. More on control and variables: Control – The part of the experiment you do not change – the part that is the same, just like it would normally be. Nothing is changed. Independent variable – The part of the experiment you change – what you are testing. Dependent variable – what changes because of the independent variable. This is usually part of the results of the experiment.
