| Explore | We know that plants perform photosynthesis are green, and you can eat some types of plants. Do all types plants preform photosynthesis at the same rate? |
|---|---|
| Research Question | How the rate of which plants from a desert biome such as cactus perform photosynthesis compares to the rate of spinach. |
| Predictions | At a lower rate because they have less water. |
| Experimental Design | We would follow the same procedure but instead of using spinach we would use cactus or succulents. The data will be recorded by time like in the base lab. |
| Conclusion | What claim can we make from our experiment? Desert plants take longer to fill its leaves with oxygen. What are possible explanations for our results? This may be because the succulent leaves we used are a lot thicker or that desert plants perform photosynthesis at a slower rate. How do the data we collected and our reasoning with scientific ideas support our claim? The only half of the succulent plant leaves in the baking soda water did not rise until 20 minutes, a lot slower than spinach leaves. What future experiments could be done to expand on the results of this experiment? We could use leaves of the same size and wait for a longer time for all the leaves to rise because only one leaf had risen in the water with breath at 22:55 when we had to clean up. If we allow all the leaves to rise, we would have more information to make out claim. |
