1. TALENT 21 ACID RAIN EXPERIMENT Your Name: Nicolette Hernandez Group Members: Gabby Ade, Grant Myers, and Dylan Horsey Period: 4

2. ASK A QUESTION  During this lab we…(explain what your group did)  During this lab we added 20 ml of water each day for 2 weeks watching our plant, to see if it would grow.  What we wanted to find out…(what was the main question for this lab?)  What we wanted to find out was would a sunflower seed grow more and faster with acid rain, or regular water.

3. CONTROL VS. VARIABLE STATE YOUR HYPOTHESIS  In this slide you are to write whether your group was a control group or an experimental group.  My group was Control.  State your hypothesis (I hypothesize…My hypothesis…)  My hypothesis is I think that the growth of the sunflower will grow rapidly with sunlight, water and oxygen.

4. DATA  Insert Chart  Insert Graph  Graph

5. DATA INTERPRETATION  What happened during your experiment? Think about: What could have affected your data (amount/type of water, sunlight, seed, etc). During our experiment the water had no chemicals and didn’t affect the plants growth.  Explain your graph-Give a three to five sentence explanation of your data.  My graph shows the difference between the plant with and without water. My plant was measured in grams each day, and 20 ml of water was added.

6. STATE YOUR CONCLUSION  My hypothesis that stated…was (correct/incorrect). Why do you think this happened?  My hypothesis that stated I thought the sunflower seed would grow rapidly with sunlight, water and oxygen was incorrect. I think it was incorrect because water is normal, but acid rain is like a chemical combined.  What was something you learned from this experiment?  Something I learned from this experiment was acid rain can have a stronger impact than regular water, when it comes to growth.  How would you alter this experiment for future use?  In the future when planting sunflower seeds I can give it more sunlight, I can also try with acid rain.
