Welcome to Science Fiction, | 0:20:04 | 0:20:06 | |
where we take the stuff you thought you knew about science... | 0:20:06 | 0:20:08 | |
..and see if we can sow in a few seeds of doubt. | 0:20:08 | 0:20:11 | |
BUD E, my old pal, can we have today's question, please? | 0:20:11 | 0:20:14 | |
Not a bother. | 0:20:14 | 0:20:16 | |
Today's question comes from Simon in Ennistymon. | 0:20:16 | 0:20:19 | |
Will singing to my plants help them grow? | 0:20:19 | 0:20:21 | |

# Let's see what the science says, Simon. # | 0:20:23 | 0:20:27 | |
When we breathe, we take in oxygen from the air, | 0:20:27 | 0:20:29 | |
which helps make energy to fuel our body. | 0:20:29 | 0:20:32 | |
This process also creates carbon dioxide and water, | 0:20:32 | 0:20:35 | |
which we then release into the air when we breathe out. | 0:20:35 | 0:20:37 | |
Now, luckily for us, plants love carbon dioxide. | 0:20:37 | 0:20:41 | |
# Don't they, Dr Knowles? # | 0:20:41 | 0:20:43 | |
They sure do, Professor. | 0:20:43 | 0:20:45 | |
Along with water and energy from the sun, | 0:20:45 | 0:20:47 | |
plants use carbon dioxide to grow, | 0:20:47 | 0:20:49 | |
while at the same time producing... You guessed it. | 0:20:49 | 0:20:53 | |
Little fluffy bunnies? | 0:20:53 | 0:20:54 | |
No, Professor! Oxygen. | 0:20:54 | 0:20:56 | |
I'm only messing with you. I knew that. | 0:20:56 | 0:20:59 | |
This process is known as | 0:20:59 | 0:21:01 | |

-Photosynthesis? -That's the one. | 0:21:05 | 0:21:08 | |
# Photosynthesis, photosynthesis | 0:21:08 | 0:21:10 | |
# Photosyn... # | 0:21:10 | 0:21:11 | |
Ow! | 0:21:11 | 0:21:12 | |
So, Simon, singing, or even speaking, to a plant | 0:21:12 | 0:21:15 | |
will help it grow, as you are feeding it carbon dioxide and water. | 0:21:15 | 0:21:19 | |
But, like, it's not because they think | 0:21:19 | 0:21:21 | |
you've a lovely voice or anything. | 0:21:21 | 0:21:23 | |
You're not that good. So that's just a load of old science fic... | 0:21:23 | 0:21:26 | |
