1. Planting Science Research Project Marion Jr./Sr. High School Science 7 Team Name: squirrel marines Presentation by: isaiah

2. Our research question was: do different amounts of carbon dioxide effect the plants germination/growth We chose our question because…the entire group thought it was a good idea and we wanted to see if it CO2 really did effect the growth

3. We predicted that… We believe that a richer amount of carbon dioxide will quicken the germination/growth because a plant needs CO2 (they also need some oxygen) to survive and to create glucose so we think that if you increase the levels of CO2 then it will grow faster I believed this would be true because…plants need Co2 but the air is a mixture of gasses so we thought if we created a environment with lots CO2 that the plant would grow/germinate QUICKER

4. Experimental Design What is the variable you are testing? Co2 AMOUNTS Briefly describe your experimental and control group. the control group was exactly the same except CO2 levels and the CO2 group was in a container in which we could add CO2 Describe what you did to make this a fair test? both containers had the exact amounts of sun, light, and water and moisture

5. Our conclusion: Are conclusion is that on march 21 are second day of collecting data only 66.66% of the CONTROL GROUP seeds sprouted when 93.33% of are co2 plants sprouted so that we believe that CO2 does increase germination speed

6. My Evaluation: Describe one or TWO specific errors that you feel your group made. I BELIEVE THAT THERE COULD HAVE BEEN MORE SUN LIGHT ON 1 CONTAINER THEN THE OTHER WHICH WOULD MAKE THE TEST UNFAIR What would you do differently if you were to do your investigation over? I WOULD HAVE DEFFINETLY MADE SURE THAT IT WAS A FAIR TEST AND I WOULD ALSO MAKE THE GROUPS SMALLER SO YOU COULD HAVE ALL MEMBERS OF THE GROUP HAVING A JOB
