LO: Explore natural selection

 

Last week, we looked at how different organisms were adapted to their environment. Those organisms that are better adapted are more likely to survive long enough to reproduce and pass on their genes. This is called natural selection.

 

This week, you are going to create a story to explain natural selection to a 5-7 year old.

 

TASK 1

Watch this video of the author Isabel Thomas reading her book "Moth: An Evolution Story". 

 

• Why do you think the ‘speckled, freckled’ wings help the moths to survive?
• Who do you think the ‘hungry eyes’ belong to?
• What do the parents pass on to their children?

 

• What has happened here?
• What is the proportion of moths with peppered wings compared with the proportion with charcoal wings?

 

• What is the threat to the peppered moths here?
• How do peppered moths survive this threat?
• The moths with which colour wings are more likely to get eaten? Why?
• The moths with which colour wings are more likely to live long enough to breed and have children? Why?

 

• What is the threat to the peppered moths here?
• How do peppered moths survive against this threat?
• The moths with which colour wings are more likely to get eaten? Why?
• The moths with which colour of wings are more likely to carry on breeding and have children? Why?

 

  • In Moth: An Evolution Story, how do humans impact the environment?

 

TASK 2

You need to decide what story you are going to write. You might like to choose:

 

TASK 3

Create your story. You might like to:

  • write a narrative
  • draw a cartoon
  • film a stop-motion animation

This is Owen's animation to explain why shorter giraffes did not live long enough to pass on their genetic information.
