Summary:
1.
Compare the reactants of photosynthesis to the products of respiration. What do you
notice?
2. Compare the reactants of respiration to the products of photosynthesis. What do you
notice?
3. What is the relationship between photosynthesis and respiration?
Part II: Webquest
Go to the following website: http://www.diffen.com/difference/Photosynthesis_vs_Respiration
Use the information there to create chart comparing photosynthesis and respiration, similar to the
example in projected by your teacher. Place this diagram on your notebook page underneath this
handout. Get a stamp from your teacher when your diagram is complete: ______________
Watch the youtube video on the website. Answer the following underneath your chart.
1. Why does respiration occur in BOTH plants and animals?
Part III: Lab (write all components of this activity in your notebook on the page under this
handout!
You are a crew-member on a space ship that is on an exploration mission searching for
life on other planets. The commander of the ship has sent you and three of your
crewmates to the surface of a newly discovered planet. Your mission is to solve a
mystery. You must find out what gas the other life forms exhale. Your only clue is a CD
video clip of one of the other life forms exhaling through a straw into a clear container
labeled “bromothymol blue.” At the beginning of the video clip the solution inside the
“bromothymol blue” container is yellow; however, after the other life form exhales into
the container for a period of time the “bromothymol blue” solution turns from yellow to
blue.
The atmosphere of this new planet is 21% oxygen and does not contain any known toxins
so your commander sends you to the surface without a space suit. You and your team are
equipped with a solution of bromothymol blue, safety glasses (four pairs), a clear
container, a straw and a plastic bag containing water and a sprig of an aquatic plant. Each
member of your team has been assigned one of the following roles: documentation
officer, timekeeper, peacekeeper, or materials manager. You have 25 minutes from the
time of your arrival on the new planet to solve the mystery and ready yourself to return
to your ship.
Upon your return to the ship you must present your findings to your commander. She
wants to know what gas the other life forms exhale, and since she is not very trusting,
you must be able to prove to her exactly how you arrived at your conclusion. She will
want to know what sorts of questions you asked to get started, the steps you took to arrive
at your conclusion, and she is particularly fond of the collection of data and presentation
of data in graphs. All of this evidence must be recorded in your notebook under this handout!!!
