Classification of Animals and plants.

 

This term in Science we have looked at grouping animals and plants.

You have learnt the 6 basic animal groups and can use the terms vertebrates and invertebrates.

 

Then last week we looked at classification keys and sorted animals and plants using a key.

When we looked a the classification key, you noticed that it only uses questions with yes or no answers.

 

Whilst you are at home for the 10 days we would like you to continue your work about Plants and animals.

 

Your Tasks:

 

1. Create your own classification Key.

You can sort 6 different leaves or plants you find in the garden or think of 6 different animals to sort. Your First question needs to split the group of items in two groups.

 You need to remember to use yes and no questions to separate your items. 

 

(Don't forget to send in your work using the Year 4 email address)

 

2. Research and create your own food chains.

 

Watch these videos about Food Chains.

What is a food chain?
A food chain is a flow of energy from a green plant (producer) to an animal (consumer) and to another animal (another consumer) and so on.

All organisms need energy to live. Energy is obtained from food. 

Green plants are the only organisms that can capture energy from sunlight and make their own food.

 

 

The start of the food chain is always called a producer.

A producer is usually a green plant.

 

The animals that eat plants are called Primary (First) Consumers. These are herbivores.

 

The next group, called the secondary consumers are carnivores or omnivores
They eat the primary consumers.

 

A Tertiary Consumer is usually the top of the food chain and eats the secondary consumers. These are carnivores.

 

In a food chain there must be arrows between each step to show what gets eaten by which animal is the stage. 

Maize is eaten by the locust, locust is eaten by the lizard and the lizard is eaten by the snake.

 

Your Task - Can you label and create a food chain?
