  • Question 1

Class 6 are investigating temperature.

They want to find out which type of mug keeps hot tea warm for the longest period of time.

They pour hot water from a kettle into a metal and ceramic mug. Then they measure the temperature change of the liquid every minute for nine minutes.

What piece of equipment will the students use to measure the temperature of the water?

CORRECT ANSWER
a thermometer
EDDIE SAYS
Temperature is measured in degrees Celsius using a thermometer.
  • Question 2

In order for Class 6 to get valid results, they must make sure their experiment is a fair test.

 

Identify the steps the students should take to make sure their experiment is a fair test.

Select two correct answers from the list.

CORRECT ANSWER
make sure the starting temperature of the water is the same for both mugs
use the same volume of water in both mugs
EDDIE SAYS
When you carry out an experiment to observe the difference between two variables (things) you must try to keep everything else constant.

In this example, the variable being tested is the type of mug. Class 6 must ensure that the only difference between the two experiments is the material the mug is made from. Everything else, like the volume of water in the mugs, should be the same.
  • Question 3

The members of Class 6 work in pairs during their investigation.

James and his friend Omar are going to work together.

 

James says: "The ceramic cup will keep the water the warmest because ceramics are insulators".

Omar says: "The metal cup will keep the water the warmest because metals are conductors and the metal will conduct the heat back into the water".

 

James and Omar have both made a __________.

CORRECT ANSWER
prediction
EDDIE SAYS
All scientific experiments should start with a prediction (or hypothesis).

Scientists, who carry out experimental research, use their predictions as a bench mark. If the results of their experiments do not match their predictions then they know that, either their experiments are faulty, or the scientific theory behind their predictions is wrong.
  • Question 4

James and Omar measure the temperature of the water in the mugs every minute for nine minutes.

They record their results in a table:

 

Time (min) Water temperature in ceramic mug (oC) Water temperature in metal mug (oC)
0 55 55
1 55 55
2 54 53
3 54 52
4 53 51
5 52 50
6 50 49
7 49 47
8 48 44
9 47 42

 

James and Omar decide to display their results as a graph.

 

Which type of graph should James and Omar draw?

CORRECT ANSWER
a line graph
EDDIE SAYS
You may not agree, but I think graphs are fab!

A graph tells the story of a scientific experiment in a way that is very easy to see.
In this example the results both show a cooling trend but in which mug has the hot water cooled the most?

A line graph is the best option because both time and temperature are continuous. You can use a line graph to estimate what the temperature of the water in a mug would have been at an intermediate value, for example one minute and 30 seconds.

Graphs are much easier to read than tables. Why don't you have a go at drawing a graph of these results?
  • Question 5

Mr Pringle, the class teacher, carried out a separate investigation using three different take away cups from the local coffee shops.

One cup was made from paper, another was plastic, the third cup was made from polystyrene.

Mr Pringle recorded in a table the total temperature loss after nine minutes for all three types of cup.

 

  Paper cup Plastic cup Polystyrene cup
Temperature loss after 9 minutes (oC) 24 19 9

 

A new coffee shop is opening in the town, what type of material should they use for their takeaway cups?

Write one word.

CORRECT ANSWER
Polystyrene
polystyrene
EDDIE SAYS
The water in the polystyrene cup is nine degrees cooler than at the start of the experiment. This water has lost much less energy than water in the other cups.
Polystyrene is used for takeaway coffee cups because it is a very good insulator.
  • Question 6

A piano teacher is tuning her piano. She is using a tuning fork to help her find the right notes.

When she hits the tuning fork on a surface, a sound is produced.

 

How does a sound travel through the air?

CORRECT ANSWER
air particles vibrate
EDDIE SAYS
Sounds are produced when an object is hit or a string is plucked. This produces a vibration which moves through air particles to the ear drum.
  • Question 7

The tuning fork is made from iron.

 

What will happen if a magnet is placed near the tuning fork?

CORRECT ANSWER
The tuning fork will be attracted to the magnet.
EDDIE SAYS
Iron is magnetic.
If a magnet is placed near to an object containing iron, it will attract the object.
  • Question 8

After hitting her tuning fork against the side of a table, a singing teacher notices that the tuning fork is slightly warmer to touch than before.

 

Name the force that is generated when two surfaces touch each other and produce heat.

Write one word.

CORRECT ANSWER
Friction
friction
EDDIE SAYS
When two surfaces touch one another friction is generated.

Think about when you sit in your parents car. Your can hear the sound of the car moving along the road. The sound you can here is the friction generated between the road surface and the tyres on the car.
Friction produces heat and sound.
  • Question 9

The singing teacher hits the tuning fork against the table a second time.

This time she hits the fork against the table with much more force.

 

What will happen to the volume of the sound?

CORRECT ANSWER
It will increase.
EDDIE SAYS
The more force that is used to make a sound the louder the sound is. This is because the vibrations carry more energy.

Hit a tambourine and think about the sound you make, hit it again a second time but this time hit it harder. What did you notice about the sound you made?
  • Question 10

Which part of the human body detects sound?

CORRECT ANSWER
the ear drum
EDDIE SAYS
Vibrations travel through the air and into the ear. The ear drum vibrates and generates a signal which is sent to the brain by a nerve.
  • Question 11

Smoking is a health risk.

It can cause lung disease and heart attacks.

Smoking is also addictive.

 

 

What is the name of the addictive chemical found in tobacco?

CORRECT ANSWER
nicotine
EDDIE SAYS
Nicotine is a very addictive substance. Nicotine is a stimulant which slightly speeds up processes in the body.
Smoking is strongly linked to lung disease and increases the risk of heart attacks.
  • Question 12

The lungs are a major organ in the body.

Breathing occurs at the lungs.

During breathing oxygen is taken out of the air and put into the blood.

 

 

Which body organ pumps blood around the body? 

CORRECT ANSWER
the heart
EDDIE SAYS
The heart pumps blood around the body. It is a very strong muscle.

Breathing occurs at the lungs, the whole point of breathing is to allow oxygen to get in to the body and carbon dioxide to leave it.
  • Question 13

Emily and Matt are investigating the effect of exercise on their heartbeat and breathing.

They are going to exercise for two minutes.

  

 

What measurements should Emily and Matt take?

CORRECT ANSWER
They should take their pulses before and after exercise.
EDDIE SAYS
So that Emily and Matt can find out exactly how exercise effects their heartbeat, they must measure their pulse rates before and after exercise.
If they do not take two measurements they will not be able to see how it has changed.
  • Question 14

What will Emily and Matt notice about the effect of exercise on their heartbeats and their breathing rate?

CORRECT ANSWER
Their heartbeats will increase and so will their breathing rate.
EDDIE SAYS
Rate means speed.
Exercise increases both pulse rate (heartbeat) and breathing rate. This is because the muscles need more oxygen, the heart and lungs work faster to get greater amounts to the muscles.
  • Question 15

When Emily and Matt carry out their exercise they are using their muscles to help them move.

When a muscle contracts, it needs energy. We get energy from our food.

 

 

Which types of food are used by the body for energy?

Choose three correct answers from the list.

CORRECT ANSWER
fats
starches
sugars
EDDIE SAYS
Starches and sugars are known collectively as carbohydrates.
Carbohydrates are broken down by our digestive system into glucose. Glucose is used by cells in a process called respiration to release energy.
Fats are also used by body cells to release energy.
  • Question 16

Meat is an example of a protein. 

Carnivores, such as lions, eat meat.

 

 

Which type of teeth help carnivores like this lion to rip and tear the flesh of their prey?

CORRECT ANSWER
canines
EDDIE SAYS
Canines are often called fangs. They are long, sharp teeth which animals use to rip meat from their prey.
  • Question 17

Primary consumers like sheep and cows have large numbers of molars in their mouths to grind and crush grass leaves.

 

 

This is an example of an __________.

Write one word.

CORRECT ANSWER
Adaptation
adaptation
EDDIE SAYS
Animals and plants that are best adapted to their habitat will survive and reproduce.
Can you think of any other adaptations that help sheep to live in their habitats?
  • Question 18

Fish live in water, polar bears live in the Arctic, the cactus lives in the desert.

 

The place where an animal or plant lives is called its _______.

Write one word.

CORRECT ANSWER
Habitat
habitat
EDDIE SAYS
Plants and animals are adapted to live in a particular habitat.
For example, a cow's habitat is a field. A squirrels habitat is a tall tree.
  • Question 19

The cactus lives in the desert.

 

 

How do human eyes see objects like a cactus?

CORRECT ANSWER
Light from the Sun reflects of the cactus into our eyes.
EDDIE SAYS
Light always travels from the light source (in this case the Sun) to an object. Objects reflect light into our eyes.
Our eyes are not a light source.
  • Question 20

The cactus has a large, fleshy, green stem and thin leaves like needles.

The cactus would lose too much water if it had broad flat leaves like an oak tree.

 

 

By what process would the cactus lose water if it had broader leaves?

Write one word.

CORRECT ANSWER
Evaporation
evaporation
EDDIE SAYS
When liquid water turns to water vapour we say it has evaporated. This happens easily in warm dry environments.
You can see this at home. Pour a small amount (a desert spoon) of water into a saucer or small plate and leave it by a warm radiator for a day or two. You will notice that the water evaporates from the saucer.
