| Explore | Plants make up 80% of all carbon stored in living things. They also make glucose to help make food for photosynthesis. They use cohesion and adhesion to absorb water up their root to their stem then leaves. Also taking in carbon and giving oxygen back. |
|---|---|
| Research Question | Would Radishes plants grow faster with more light with a longer photoperiod of light than one with a shorter photoperiod light. What we know is that to make photosynthesis, plants need water & light to make glucose & oxygen which creates food for the plant. We also know that radish seeds take about 5-10 days to sprout. |
| Predictions | We believe that the Radishes plants will grow bigger with more light than water in the classroom. |
| Experimental Design | Two cups with fertilized soil and Radishes seeds in. They will be water every week. Both will be in a 6 inch pot. Cup A has 3 light fixators - Will be given 1 inch of water -Will be given 12 hours light Cup B has 2 light fixators. -Will given 1 inch of water -will be given 6 hour light |
| Conclusion | Result came in and our prediction was wrong. Cup B was more successful. Growing 6 1/2 cm with light green leaves, a skinner stem. As well as a different formation in the two new leaves which are more outward. While Cup A grew 3 1/2 cm with dark green leaves, a thicker stem. Also the two new leaves were more curved in. We also noticed that Cup B leaves were more fuzzier than Cup A. So to conclude, Cup B that had 2 light fixators and 6 hour timer was more successful than Cup A that had 3 light fixators and 12 hour timer. |
