The solid turns the water misty.

B The solid cannot be seen.

The liquid is clear.

C The solid cannot be seen.

(c) The teacher tells Mia the names of the four solids.

Draw FOUR lines to match each solid to its name. Use the information from the table to help

you.

3. Filters

(a) Some mixtures can be separated with a filter.

Filter

4

The table below shows some different mixtures.

Complete the table to show if a filter can be used to separate each mixture. Write yes or no.

One mixture has been done for you.

(b) Jai has a mixture of chalk powder, sugar and water. He tries to filter the mixture using kitchen foil.

The foil does not separate the mixture. The foil does not break.

Explain why the foil does not separate the mixture of chalk, sugar and water.

.................................................................................................................

(c) Jai makes a new filter using a paper towel.

Describe how Jai could separate the sugar from the water.

Mixture Can the mixture be separated

by a filter? Yes or no?

Sand and stones no

Soil and water

Sand and soil

Salt and water

He uses the paper towel filter to separate more of the chalk, sugar and water mixture.

The chalk stays on the paper towel.The water and sugar go into the beaker.

Wooden spoon Sieve

Weighing scales Filter

(b) Sophie thinks of some things you can do in the kitchen. .The activities cause the materials to change.

Complete the table by writing solid, liquid or gas in each box to show how the materials change. One box has been done for you.

d) Sophie’s dad heats water in a saucepan. The water does not boil. The level of the water in the pan goes down as the water is heated.

Name the scientific process that causes the level of the water to go down as it is heated.

......................................................

(a) Sophie and her dad are cooking in the kitchen. Sophie spills some flour onto some raisins.

Activity Before After

5. (a) Here are pictures of two fully grown foxes from different parts of the world.

A B

Fox A is adapted to a cold part of the world.

It has a thick layer of fur.

Write ONE other way some mammals are adapted to cold climates.

......................................................................................................................

(b) A female fox gave birth to a litter of cubs in three successive years.

Each litter had six live cubs born into it.

The graph shows how many fox cubs survived to become adults from each litter.

Write ONE possible reason for the change in the number of fox cubs that survived from the third litter compared with the second litter.

......................................................................................................................

7

(c) The number of adult foxes in the area changed over three years.

Write ONE possible reason for the change in numbers of adult foxes from 1994 to 1995.

......................................................................................................................

......................................................................................................................

6. (a) Robert and Lucy carried out a survey of three sites in a wood.

At each site they looked at the number of different species of plant, the average height of the nettles and the intensity of the light.

They recorded their measurements in a table.

Add two more environmental factors to the list below which could account for the numbers of different species of plant at each site.

(i) Light intensity (ii) (iii)

Year 1994 1995 1993

Number of adult foxes 11 16 14

7) . (a) This diagram shows the life cycle of a red admiral butterfly.

Jo wants to get rid of all the nettles in the school wildlife area. This will affect the red admiral butterfly.

Give TWO different reasons why nettle plants are important in the life cycle of the red admiral butterfly.

(i) ............................................................................................................

(ii) ............................................................................................................

8. (a) These stages in the life cycle of a flowering plant are not in the right order.
