1. May the Light be with you
By Kenadi Browne
The effects of different artificial and natural light on the height of plants.
“The plant’s too tall—it’s going to burn!”
Keep this page simple. This is your first page for your presentation.

2. About Me I like chemistry and biology Catastrophic events presentation
Economic botanist
Plant and people relationship
Remember that you should have simple bulleted list or picture to help “show” you audience who you are. DO NOT write an autobiography on this slide.

3. Scientific Background
Similar to Biology
Focused on Botany
Julius von Sachs—German botanist
Again, don’t write a paragraph on this slide. A few bullets and pictures to “show” your audience who you are talking about.

4. Introduction
How do different types of artificial and natural light affect the height of a plant?
If 5 different kinds of light are used to grow plants then the plants will grow best in sunlight, then grow light, then LED light, then black light, then no light because sunlight has the best spectrum of light for plant growth.
Have your entire question and hypothesis on this slide, but summarize your reasoning. You want to talk about it, not have students read it while you talk.

5. Materials 5 tomato plants
Black light bulb, grow light bulb, LED light bulb
5 boxes/large containers (to contain plants)
4 covers for blocking light
Measuring tape or meter stick
Access to power (for lights)
Access to water
Compost and/or soil
4 plant cages
List with a quantity. When you present this you will just touch on key materials, but don’t read all of them to us.

6. Materials

7. The Process Five plants in boxes, three connected to power
200 mL/ water on first day, 100 mL after
Mimic sunlight patterns
Repeated for 13 days
Measured plants every 3 days
DO NOT copy your entire procedure. Give us a brief idea how you did this and include mostly photo’s or video instead of typed words. You can explain your photos or just narrate your video.

12. Measuring plants

13. What did you control? MV: Type of Light RV: Plant Height
Time light is on
Type of soil
Type of plant (tomato)
Amount of water given to plants
MV: Type of Light
RV: Plant Height
Type a list and talk about why these things were important to keep constant.

14. Data Table Five Types of Light Vs. Height of Plants Over Time 19.5 14

Only your data should be on this page. Don’t read us your numbers. Point out any erroneous data that might have messed up your results.

15. Graph Five Types of Light Vs. Height of Plants Over Time
Explain what the data means. Are there any trends in your graph that you need to point out. Could any errors have factored into your results?

16. Results Grow light = greatest effect No light = least effect
Possible heat effect—grow light and black light, maybe LED

17. Conclusion Type of light does affect plant growth
Hypothesis mostly supported
Overall Growth: 19.5 (sun), 14 (black), 30.5 (LED), 32 (grow), 12 (no)
Because of light spectrums—red, blue, green spectrums
Have a timed light
How does density of soil affect plant growth?
This is the most important part of your presentation. It should be clear and to the point. Avoid using the words I was wrong, or I was right. Always refer back to your original hypothesis. RAPPIN should be used as a guide, but don’t keep to that rigid format.
