PRESENTATION OUTLINE
Step 1: Ask a testable question.
How does ___effect _____?
How does refrigeration effect how quickly the bulb grows?
How does bone meal effect the speed of the growth?
Does different types of water effect plant growth?
Step 2: Form a Hypothesis
Format: If ___________,
(experimental procedure)
Then __________,
(prediction)
Because________.
(why you made this prediction)
Hypothesis: If one tablespoon of bone meal is added to the hole when a daffodil bulb is planted, then the height of the grown daffodil will be taller, because phosphorus makes plants healthier.
Hypothesis: if daffodil bulbs are placed in the fridge one month before plantning, then the daffodils will begin growing sooner because temperature change causes bulbs to come out of dormancy.
Step 4: Determine Necessary Materials
Materials:
1. Refrigerated daffodil bulbs
2. Room temperature daffodil
bulbs
3. Rulers
4. Trowels
5. Bone meal
6. Triple beam balances
7. Tape measures
8. Raised beds with Cartesian grid
9. Gloves
10. Tablet
11. Buckets
12. Knee pad
13. Tablespoon
14. Plot experiment signs
15. Thermometer
16. Temperature probe
