Photosynthesis+and+Respiration

=Objectives=
 * 1) Identify the reactants and products of cell respiration
 * 2) Identify the reactants and products of photosynthesis
 * 3) Describe how photosynthesis and respiration work together

=Part 1= > 1. Go to the following website: [] > 3. Click on the second choice, **“Carbon transfer through Snails and Elodea”.** > 4. As you go through the website you will answer questions on the website on another sheet of paper. > > **Problem: Read the problem and answer the following questions** > 1. What is the problem that you are going to research in this lab? > 2. What is your experiment going to be about? > 3. After answering the questions click on the **Explore button at the top** > **Explore: Click on all the objects in the lab and answer the questions below** > 4. //Beaker of Bromthymol Blue (BTB) Solution//: a. What is this used to test for? > b. Why is it green? > 5. //Pond snails//: How do they breathe? > 6. //Elodea//: What is this? > 7. //Test Tubes:// What will you be using this for? > 8. //Grow Light:// Should you expose your setup to light? > 9. //Test Tube Rack Cover:// When would you use this item? > 10. //CO2-O2 Cycle Poster//: a. What gas will snails give off? > b. What gas does the elodea take in? > 11. //Color Key//: a. What color will the solution be if there is **no Carbon Dioxide:** > b. What color will the solution be if there is **lots of Carbon Dioxide:** > **Directions:** > 1. You can now move onto the experiment by **clicking Procedure** > 2. Write your hypothesis (refer back to the problem): **you will be printing out this lab notebook when you are __finished with the whole lab__** > 3. Click the arrow to move the next step and set-up your experiment. > 4. Answer how you will measure the dependent variable (look back at your materials) > 5. Pick one of the two independent variables to use (**do not pick how light affects it**) > 6. Write down your control group for your experiment > 7. You need to choose **at least 3** test tubes. > 8. Setup the test tubes to appropriately test the independent variable (**remember to keep everything else constant)** > 9. Once finished writing your experiment press the yellow arrow to move to the next step. > 10. Close your notebook and start your experiment by following the steps. > 11. Open up your notebook and record your predictions. > 12. Run your experiment (**Make sure you put your tubes under the light**) > 13. Open up your lab notebook, record your results and answer the questions. > 14. When finished print out your lab notebook and you can go back and run other experiments. > =Part 2:=
 * 1) You will investigate the relationship between photosynthesis and respiration through a snail and elodea lab
 * 2) **Directions:**
 * 1) You will take a set of cards and complete the following based on what you found in the lab
 * 2) First put the cards in order to show the reactants (what is used) and the products (what is made) by the snail during cell respiration
 * 3) Once you figured it out develop the following Notes
 * 4) Define cell respiration
 * 5) Write out the equation
 * 6) State in what organelle it takes place in
 * 7) Explain the importance of the process
 * 8) Second put the cards in order to show the reactants (what is used) and the products (what is made) by the plant during photosynthesis
 * 9) Once you figured it out develop the following Notes
 * 10) Define photosynthesis
 * 11) Write out the equation
 * 12) State in what organelle it takes place in
 * 13) Explain the importance of the process
 * 14) Now arrange the cards to show how photosynthesis and respiration are connected and work together
 * 15) Once you figured it out develop the following Notes
 * 16) Show the cycle in your notes
 * 17) Explain why each process is important to each other
 * 18) Describe why it is important for plants to complete each process
