Science Songs - Biology (Photosynthesis)

Songs are fun way to listen to English. Here are two songs about the same thing: "photosynthesis"


Song 1 - Intermediate



As you listen, make sure you can answer these questions!
According to the song:
1. What do plants use to make Cellulose?
2. What do plants use CO2 to create?
3. What does chlorophyl capture?
4. Why can't people "photosynthesize"?

Finally, can you now explain what photosynthesis is?
Photosynthesis is how . . .

Song 2 - High Intermediate +
Here is a hipper, faster (and harder) version:


According to the song:
5. How many processes or "reactions" are mentioned?
6. What are they?



Answers:
1. sunlight and air
2. oxygen
3. sunlight
4. people aren't green!
5. 2
6. The light reaction & the Calvin cycle (dark reaction)
Lyrics to song 2
Lyrics
Photosynthesis, lets get into this
Discussion of sunlight, and transfer of energy.
Photosynthesis, lets get into this
Process of chemical reactions and synergy.
Plants take water, sun, and CO2,
to make glucose: the sugar that they use for food
They also put oxygen into the air
So we can share, because oxygen is everywhere
The energy transforms from solar to chemical
All the time, everywhere, the process is identical
In every plant, and every tree
Enabling all living things to be
Photosynthesis, lets get into this
Discussion of sunlight, and transfer of energy.
Photosynthesis, lets get into this
Process of chemical reactions and synergy.
Photosynthesis, lets get into this
Discussion of sunlight, and transfer of energy.
Photosynthesis, lets get into this
Process of chemical reaction
Lets take a look at the light reaction
Making chemical energy when light is captured
electrons flow through the photo systems
Flowing so fast you might have missed em
Within the chloroplast lies the action
The thylakoid membrane is where it happens
ATP and NADPH
Are products of light, water, air, and space
Photosynthesis, lets get into this
Discussion of sunlight, and transfer of energy.
Photosynthesis, lets get into this
Process of chemical reactions and synergy.
Photosynthesis, lets get into this
Discussion of sunlight, and transfer of energy.
Photosynthesis, lets get into this
Process of chemical reactions
The Calvin cycle, or dark reaction
Doesnt need direct sunlight for it to run right.
CO2 from the air enters the chloroplast
Mixing with organic molecules for the last time
With the help of the enzyme Rubisco
Carbon Fixation—I thought you knew this yo!
It forms a carbohydrate known as G3P
Its created, recreated, and recycled you see
Photosynthesis, lets get into this
Discussion of sunlight, and transfer of energy.
Photosynthesis, lets get into this
Process of chemical reactions and synergy.
Photosynthesis, lets get into this
Discussion of sunlight, and transfer of energy.
Photosynthesis, lets get into this
Process of chemical reactions
Leaves on trees and even weeds meet needs
Making oxygen we need to breathe
You want to learn it with ease? You want to master the keys?
Its photosynthesis, listen to this please
Photosynthesis, lets get into this
Discussion of sunlight, and transfer of energy.
Photosynthesis, lets get into this
Process of chemical reactions and synergy
Photosynthesis, lets get into this
Discussion of sunlight, and transfer of energy.
Photosynthesis, lets get into this
Process of chemical reactions
