1. Scientific Method
“Dancing Plants”

2. - What do you want to learn more about…#1
Asking a QUESTION:
- What do you want to learn more about…
Which type of music will have the greatest effect on a plant’s rate of growth: Hard rock, pop, or classical?

3. #2 Gather background INFORMATION:
- What information can we uncover to help us form an educated guess?

4. Forming a HYPOTHESIS: #3
- Educated guess of an answer to the question
- Should be an “I believe…because…”
Statement (well supported) #3
I believe that hard rock music will have the greatest effect on a plants growth because I believe it produces greater sound waves and vibrations, which in turn will stimulate the plants growth.

5. Conducting the EXPERIMENT:#4 a.
Materials
Conducting the EXPERIMENT:
- Test your hypothesis
- Written and carefully followed step-by-step experiment designed to test hypothesis
12 -5” pots
36 marigold seeds
6 cups of potting soil
1200 ml of water
3 CD players
3 CDs –
AC/DC,
Brittany Spears,
Andrea Bocceli
1 – 12” ruler
4 different locations

6. b. Procedure - Step-by-step format - Numbered steps - Direct commands
Measure 3 oz. of soil into “ flower pots.
Place 3 marigold seeds together in the soil in the center of the pot
Cover seeds with 1 oz. of soil
Add 10 ml of water to each pot
Place pots in sets of 3 in 4 different locations away from each other
Etc. …….
- Step-by-step format
- Numbered steps
- Direct commands
-Repeatable b.
Procedure

7. - Identify the control group if applicable
Controlled Variable = plant type, amount of soil, sunlight, water, and time music played
Independent Variable = types of music
Dependant Variable = amount of plant growth
4) Control Group = plants grown in absence of music c.
- State the controlled (constant), independent (manipulated), and dependant (responding) variables
- Identify the control group if applicable
Variables

8. ANALYZE RESULTS: #5 Define qualitative and quantitative data!
-Interpret the information collected during the experiment
-Data includes charts, tables, PICTURES, and graphs (excel)
Define qualitative and quantitative data!
