Article 4: Psychedelic Space Plants

Did you ever wonder why plants are green and not red?

If plants were to absorb green and reflect red we would have magenta colored palm trees. This article from Discovery Magazine discusses how plants evolved chlorophyll to absorb red and blue rays from the sun and reflect the green.  The ozone and oxygen in the earth's atmosphere absorb the blue and ultraviolet leaving more red to pass through. What happens if there is a sun cooler or hotter than the earth's sun?   Read the article and find out how plants may have different colors depending on the rays they absorb and the rays they reflect.
This article is good for a class discussion to see what color plants we could have if we had extra-solar planets.

Website 4: Photosynthesis Quizzes and Games

                                                                           

This website NeoK12 has educational videos, lessons and games for all grade levels.  Go to this interactive fun-filled website and see what you know about the process of photosynthesis.   It has two quizzes where you click on  a question card then click on an answer card to reveal a picture.  You will also find two diagrams to label, one on the photosynthesis and one on the anatomy of a leaf.  The vocabulary game presents a photosynthesis related word, a question, and you have to answer yes or no. All the games and quizzes are grade-level appropriate.  I think it is a great assessment tool where you can test yourself and see how much you have learned.  There is also an extensive list of educational videos on photosynthesis.

Video 4: Photosynthesis Rap         

                                     

WARNING:  After watching this video you might find yourself singing this Photosynthesis rap!

This rap is by Rhythm, Rhyme, & Results.  The images that accompany the rap go very well with it.  The rap explains the process of photosynthesis step by step. It lists all the reactants, where they are found,  and the products of the reaction.  It goes to the more detailed phases, the light reactions, the Calvin Cycle and where they occur. It also shows the importance of photosynthesis to life. It is amazing how much material is covered through one song.

I think it is a great review of the whole process of photosynthesis, the repetition of the lyrics will definitely  help you remember what photosynthesis is all about.  It is a great way to learn the process if you do better with visual learning.

Book 4:  Photosynthesis

                       

Do you know what happens in the electron transport cycle of photosynthesis?  

Do you want to know why and how photosynthesis is an important biological function?

You will find these answers and much more in this book. According to the reviews I read, this book covers all aspects of photosynthesis.  Although the book might be more of a college level,  you will be able to use it because it explains some of the most complex concepts in a user-friendly way.  It includes many colorful illustrations and plates which make this complex topic simpler.  I wil assign some reading from it. I will also use it in class because it includes a set of experiments that are described and explained.

Book 3: Eating the Sun: How Plants Power the Planet

Did you know that the number of pigments needed to produce one molecule of oxygen in sunlight is 2480? This is an example of what you will find in this wonderful book.

The reviews I read on this book are excellent.  The author of the book,  Oliver Morton, is an award winning science journalist.  Eating the Sun is not only about plants and photosynthesis, it is about our planet.  It has three main parts. in first part, Morton describes the process of photosynthesis, traces back the history of photosynthesis and the scientists involved.  In the second par,t Morton discusses how plants might have played a role in developing animal life and the third part discusses human activity and climate changes.

I chose this book because it integrates the process of photosynthesis with history, scientists' discoveries and the concept that plants might have kick-started the cycle of life.  How interesting is that? Skim through some pages by going to the link.  I will be assigning reading from the book so we can have discussions.

Video 3: Photosynthesis - Biology in a Few Minutes

                                                                                                 

                   
Do you know the equation of photosynthesis?  Do you know that photosynthesis involves a light dependent reaction and a light independent reaction (Calvin Cycle)? Where does each reaction occur? What are the reactants in each and what are the ending products?

Watch this video and see if you can answer some or all of these questions.  This video does not have animation or colorful diagrams but it answers all these question by creating a very informative chart and explaining how you get to the final equation of photosynthesis.

Website 3: Sweet Secret: How Plants Use the Calvin Cycle to Make Sugar out of Thin Air

This website from National Geographic is a fun and interactive website about the Calvin Cycle.  The Calvin Cycle is a part of the photosynthesis process.  You will find an interesting article about the Calvin Cycle, a great illustration of the cycle as well as plant photos. There is a vocabulary tab section where you can enhance your scientific vocabulary. The set up  is geared for ages 11-18 so you will enjoy it.

By reading the article, you will found out that the cycle is named after the Chemistry Nobel Prize winner Dr. Melvin Calvin, who was nicknamed "Mr. Photosynthesis". You will find fun facts about how and where he came to his discovery and also learn about the cycle in detail.
