This term we are looking at adapations and how living things can adapt to survive in their environment. What are the two types of adaptations we have looked at ?
Today you are going to be a predator going on the hunt for your prey! Today you are looking for coloured toothpicks out on the school oval. You will notice that some of the toothpicks are more visible (easier to see) than others that are more camouflaged.
Camoulfage is an adapation that helps living things survive. IT allows them to be hidden from their predators or hard to see. Plants and animlas arevery clever the way they use camouflage to survive.
There are different types of camouflage.
-Concealing colouration is where the animal (or plant) matches the background colour or pattern where it is most usually found.
-Disruptive colouration is where the animal has spots or stripes. Animlas that cannot see in colour find it difficult to identify patterned animals against a mottled background.
Animals can use colour to stand out in their environment. Many poisonous animals are brightly coloured as a warning to possible predators, saying ‘Stay away from me!’
Today you are going out to the oval. Mrs Smythe would have distributed (scattered) some coloured toothpicks in a certain area of the area.
You are to be a predatory bird called the ‘toothpick bird’!
You will have 15 seconds once I say “hunt!” to run to the grassed area and pick up as many toothpicks that you possibly can. At the end of the 15 seconds I shall yell “STOP!” HYPOTHESIS-Which colour toothpick do you predict will be the most easiest to see and collect? Why? Which colour will be the most camouflaged?
In your science books you need to record the amound and colour of the toothpicks you collected (Eaten) Which colour toothpicks got collected the most of? Which colour got collected the least? Why do you think this was the case?
We will repaeat the 15 seconds of searching and see if you collect more or less toothpicks this time. Record the colours collected and again list the most and least colours you have and the grade.
