1 The diagram is a model of the human circulatory system

The arrows show the direction of blood flow through the heart and blood

vessels

blood vessel D

blood vessel C

heart lungs

body parts

(a) What is the function of the heart?

[1]

(b) What is the name of the type of blood vessels labelled A and C?

[1]

pump the blood to all body part

Arteries

(c) What is the name of the type of blood vessels labelled B and D?

[1]

(d) The blood circulatory system in humans is called a double circulatory system

Use the arrows on the diagram to suggest why

[1]

(e) Write down one function of the blood in the circulatory system

[1]

Blood caries food and oxygen

veins

In one circulation, the blood vessels bring blood without oxygen to the lungs and return to the heart

In other circulation, the blood vessels bring blood with oxygen and food to body parts and return the heart.

Because it has two separate circuits and blood passes through the heart twice:

- the pulmonary circuit is between the heart and lungs

- the systemic circuit is between the heart and the other organs

2 Look at the table of properties of some substances

substance melting point in o C boiling point in o C conductivity electrical

bromine −7 58 low copper 1085 2562 high iron 1540 2862 high mercury −39 357 high oxygen −218 −183 low silver 961 2162 high

(a) Which change of state happens to oxygen when it boils?

[1]

(b) What is the meaning of the words boiling point?

[1]

(c) Melting point, boiling point and electrical conductivity are all properties of a

substance

Write down one other property of a substance

[1]

(d) Room temperature is 25°C

Bromine is a liquid at room temperature

Complete the sentence to explain why

Bromine has a melting point than room

temperature and a boiling point than room

temperature

[1]

Bolling point mean when the liquid at that temperature, it will boil

lower

higher freezing point

evaporating

3 Blessy uses a periscope to look over a wall at a light source

(a) Look at the diagram

The periscope has two plane mirrors

A ray of light enters the periscope and finally enters Blessy’s eye

Complete the path of the ray of light on the diagram until the ray of light reaches Blessy’s eye

Blessy’s

(b) Name the process that happens when the ray of light hits the plane mirrors

[1]

reflection

5 Priya and Rajiv are visiting this rainforest

Priya and Rajiv are worried they may be bitten by an insect and get an infection

(a) Describe two ways Priya and Rajiv can avoid being bitten by insects in the

rainforest

(b) Some diseases are caused by infection of bacteria

Write down the name of two other types of organisms that may cause a

disease by infection

6 Yuri investigates how many sugar cubes dissolve in different temperatures of

water

In his first experiment Yuri:

• pours 100cm3 of water into a glass beaker

• measures the temperature of the water

• keeps adding sugar cubes to the water until no more sugar dissolves

• records the number of sugar cubes that dissolve

He repeats the experiment four more times

Each time he uses water at a different temperature

(a) Write down a prediction for this investigation

Use your knowledge and understanding of particles to explain your prediction prediction

explanation

[2]

(b) Name a piece of equipment used to accurately measure 100cm3 of water

[1]

(c) Name a piece of equipment used to measure the temperature of water

[1]

(d) Explain why Yuri uses 100cm3 of water in each experiment

[1]

(e) Write down the dependent variable in this investigation

[1]

When the temperature is higher, the sugar dissolves faster and more

When the temperature is higher, the sugar is easy to dissolve

mesuring jar

thermometer

To have fair tests.

temperature , sugar

7 Scientists use models to describe electrical circuits

Look at these two electrical circuits

circuit A circuit B

Both circuits have a cell and wires

(a) Describe two other similarities between the two circuits

1

2

[2]

(b) Describe two differences between the two circuits

1

2

[2]

They both have lights

They both have switchs

In circuit 1, the switch is close but in circuit 2, the switch is open

Circuit 1 is working , but circuit 2 is not working.

8 Mia finds some data about the eight planets of the Solar System

Look at the table of data

planet

radius of the planet

in km

distance of the planet from the Sun

in millions of km

mean surface temperature

of the planet

A 2440 58 280

B 3389 228 −55

C 6052 108 460

D 6371 150 14

(a) Which letter shows the planet with the coldest mean surface temperature?

[1]

(b) What is the name of the planet that is the furthest away from the Sun?

[1]

(c) Which letter shows data for Mercury?

[1]

(d) Mia thinks that as the radius of a planet gets bigger, the planet is further away

from the Sun

Is she correct?

Use data from the table to explain your answer

[1]

F

Neptune

A

No

Because H is the biggest radius but it not the furthest plant

9 Look at the table of data

It shows the mass and weight of the same object in different parts of the solar

system

part of the solar system

mass of object in

weight of object in

Earth 10.2 100

Mercury 10.2 38

Pluto 10.2 6

the Moon 10.2 17

an asteroid 1

(a) Complete the table by writing the mass of the object on an asteroid

[1]

(b) The unit for mass is missing from the table

What is the unit for mass?

[1]

(c) The unit for weight is missing from the table

What is the unit for weight?

[1]

(d) Describe the difference between mass and weight

[1]

(e) Explain why the weight of the object is smaller on the Moon than on Earth

10.2

newton kilograms

mass is your amount, can know by stepping on the scale.

Weight is the gravity that push you down, can know by using newtonmeter
