Can any Connections academy students help me with this Photosynthesis portfolio 3
anyone got the answers?
I need the conclusion
CaCO3 ---> CaO + CO2 this is the reaction caused with one of many materials.
Some dry leaves floated and others sank
Some floated some sank
Quanitive
I have the answers for 2,3,4,5 but I need the conclusion
In order to answer the questions in your Photosynthesis portfolio, you will need to refer to the experimental data and observations that you have gathered. Here are the steps to help you find the answers:
1. Find the experiment description and materials list provided in your portfolio or lab notes. Look for the material that represents carbon dioxide (CO2). It could be mentioned directly or implied through the materials used.
2. Look for the section where the control experiment is described. Check for information on whether the leaves floated or sank, how many leaves were involved, and the time of observation.
3. Similarly, locate the section that describes the blue light variable experiment. Look for details on the floating or sinking of the leaves, the number of leaves, and the time of observation.
4. Determine whether the data gathered is qualitative or quantitative. Qualitative data refers to descriptions or characteristics, while quantitative data involves measurements or numerical values.
In the conclusion section, you will need to provide explanations based on your experimental setup and results. Here's how to approach each question:
1. Describe your experiment by stating the independent and dependent variables involved. The independent variable is the variable that you deliberately manipulate, while the dependent variable is the one that is measured or observed and affected by changes in the independent variable.
2. Compare and contrast Graph A and B by identifying similarities and differences between the two. Look for patterns or trends that are similar or dissimilar in the graphs. You can consider aspects such as the shape of the graph, the rates of change, or the overall trends.
3. Determine which experiment had the faster rate of photosynthesis by checking which experiment had all 10 of the leaf discs floating first. Note which experiment achieved the desired outcome more quickly.
4. Evaluate whether your hypothesis was supported or rejected based on the data and observations from your experiment. Explain the reasons behind your conclusion.
Remember to refer to your experimental data, observations, and any graphs or charts that you have created during your experiment to provide accurate and detailed answers.
