Week 2 - Science
This week we are continuing our science topic exploring the different areas of EVOLUTION.
The topic area for this week is ADAPTATION
Today we would like you to create an information sheet / fact file about the work of Charles Darwin.
Use the information below to help you do this.
- video link
- power-point presentation
- fact file about Charles Darwin
Today we would like you to research a bit more about adaptation and using the information you have learnt about Charles Darwin, look at a few different animals have adapted to their environment and how they have done this.
Start by watching the video and reading some of the information on adaptation.
Think about these questions:
- What is adaptation?
- How do animals adapt?
- Why do animals and plants adapt?
- What creates the need for animals and plants to adapt?
Make some notes in your work books and try and answer the questions as best you can.
Think about Darwin's research into the Galapagos finches.
Darwin noticed that the finches adapted their beaks so that they could eat enough food to survive on the Galapagos islands.
Over time, the finch with smaller beaks died out and the finch offspring were born with a larger beak to eat the larger food.
You are going to investigate which type of "beak" is the most successful for picking up each type of "food".
Remember: your bird needs to "eat" as much as possible to stay alive!
From home gather some different types of food for your "bird" to eat, representing different seeds, nuts and other food:
- lentils (small seeds)
- beans (larger seeds)
- maltesers or other round sweets (even larger seeds!)
- marshmallows (squishy bugs)
- strawberry laces / spaghetti (worms)
- biscuits (small mammals)
If you do not have these, don't worry you could use other items such as paper (scrunched up or cut into strips), cotton wool or other material
You will also need some different items that will serve as "beaks" for your birds:
- bulldog / hair clip
- wooden skewers
- cardboard straws
- wooden spoons
Plan your experiment!
You are going to use the object to pick up the seeds and see which object (beak) picks up the most "seeds"
Complete a plan into your work book of how you are going to complete your experiment. Think about what you want to find out and what you will need.
You can complete this as a table (see example below) or as sentences into your book.
Carry out your experiment!
Use the different objects to see how many of each item you can pick up in 30 seconds.
Record your results in a table:
Today we are going to look at the results of your experiment.
Don't worry if you did not manage to finish your experiment yesterday, Use today's lesson to finish that off too.
What did we find out?
Results: How are you going to present your findings?
Using your table of results draw a graph to show your findings.
Here is an example to help you.
1. Give your graph a title, what information is it showing?
2. Label the x axis (along the bottom) and the y axis (at the side)
The x axis would represent the "beak" (object that you used to pick the food up).
The y axis would represent the numbers (how many "seeds" the beak picked up).
3. Think about the "scale", is each square representing 1?
Conclusion: Have you answered your original question? Have you used ?scientific language?
Write a short paragraph about your experiment.
- What did you want to find out?
- How did you do it?
- What do your results show?
Use your experiment plan to help you with this.
Improvements: How could you improve your investigation to make your ?results more reliable?
Within your conclusion, think about how you could improve the experiment if you were to do it again.
- your results, were they what you expected?
- the equipment, did it show what you needed?

Today we are going to look at how plants adapt and change to survive in their environment.
Watch the video (click the link below) to learn more about what plants need to survive and how they may need to adapt.
Make notes in your work book.
Watch the video clip and listen to David Attenborough talk about how plants how adapted in the rainforest in order to survive.
Look closely at the plants that he talks about.
- how do they collect water?
- what are their leaves like?
- where do they grow? high up or low down?
- do they need much sun light?
Look at the pictures of the plants below.
How have they adapted in order to survive?
Use the information you have learnt from the video and the information pack to think about what parts of a plant may need to adapt for it to survive.
Where the plant is growing.
- Why is it growing there?
- What might be near that it needs?
Look at its leaves.
- What shape are they?
- What colour are they?
Why not have a go at drawing each plant into your work book and write the explanation next to it.
