Do you think that Marcus can retrieve the situation, by allowing the mixture to cool back to 115oC, and then pouring it out to make yummy fudge?

 

#8795 q20

Yes - by allowing it to cool to its setting point it will be fine

No - it's irreversible and he'll end up with burned sugar

No - it will all have evaporated away

  • Question 1

Oscar has plugged the kettle in to make a cup of tea.

 

Kettle

 

He notices that as the water inside heats up, the kettle starts to produce a vapour from its spout.

 

Complete the sentence:

CORRECT ANSWER
EDDIE SAYS
What does Oscar see coming from the spout? Steam (it cannot be "vapour" as that's already given in the sentence). What's steam composed of? Water molecules (

H20).

  • Question 2

The kettle makes a bubbling noise as the water inside reaches boiling point.

 

Boiling kettle

 

What temperature will the water in the kettle be now?

CORRECT ANSWER
EDDIE SAYS
What's the boiling point of water? 100 ° C.
  • Question 3

Oscar decides to hold a plate near the spout of the kettle so that the hot vapour touches the plate.

 

He notices droplets of water forming on the surface of the plate.

 

Condensation

 

What do we call the process that turns the vapour into droplets?

CORRECT ANSWER
condensing
condensation
condense
condensed
EDDIE SAYS
It's really important to know the processes that occur when a substance changes its state. Here, a vapour/gas is being cooled to form a liquid. That process is called condensation, which also happens to be the word we use for droplets of water forming on a cold surface.
  • Question 4

If Oscar collected some of the droplets of water, where in the kitchen could he put them to make them turn into a solid?

CORRECT ANSWER
EDDIE SAYS
How do you turn droplets of water into a solid? Cool them down/freeze them. What in the kitchen can do that? The freezer (or the freezer compartment of a fridge).
  • Question 5

Once Oscar had made his cup of tea, he decided to look up further information on other substances which change their state.

 

He discovered that molten iron changes into solid iron at 1540 oC.

 

What is this change from molten iron to solid iron called?

CORRECT ANSWER
Freezing
EDDIE SAYS
This is a hard one to nail in your head! In our minds the word "freezing" = cold. What's cold about 1540 oC? We're based on water, so words like boiling and freezing mean hot and cold to us. As a scientist, you have to strip that away and concentrate on the process - liquid iron cooling into solid iron is simply liquid to solid. It's freezing!
  • Question 6

Here is a chart which lists the different changes of state.

 

Decide whether that change occurs through being heated or being cooled and click the correct box.

CORRECT ANSWER
 Being heatedBeing cooled
Melting
Condensing
Freezing
Boiling
EDDIE SAYS
Did you get that OK? Hopefully, you know that freezing is being cooled and boiling is being heated. That leaves the two slightly harder ones (but not too difficult!).
  • Question 7

Here is a picture of a thermometer:

 

Thermometer

 

What is the reading on the scale?

CORRECT ANSWER
EDDIE SAYS
Reading a scale is a vital skill for a scientist. Being able to work out what the lines on the scale mean when there are no numbers there is terribly important! How many lines between 0 and 20 oC? There are 9, so each line must be worth 2 oC. How many lines below 0 oC is the liquid in the thermometer? The answer's four lines below. So, that minus 8 oC. Yes?
  • Question 8

While Oscar is looking up about substances changing state, his mum uses some of the hot water in the kettle to make herself a cup of black coffee.

 

Fill in the gaps in this sentence:

CORRECT ANSWER
EDDIE SAYS
Did you work that one out? The coffee granules dissolve (not melt, liquefy or disappear) and the brown liquid is a solution, believe it or not.
  • Question 9

The fact that the coffee granules disappear to form a clear brown liquid shows that, in water, the coffee is...

CORRECT ANSWER
soluble
EDDIE SAYS
Bit of a trickier one that - you need to know your dissolving words! If a solid dissolves in a liquid, then it is soluble in it. Insoluble is the opposite, solvent is the name of the liquid doing the dissolving (that's water in this case) and solution is what results.
  • Question 10

Oscar's mum stirs her coffee and leaves the wet spoon on the kitchen surface.

 

After an hour the spoon is dry.

CORRECT ANSWER
EDDIE SAYS
What's going on here? The wet spoon is dry. Where's the water? In the air - it evaporated away. What does that leave? A brown ring of coffee solids, which were in solution with water.
  • Question 11

The coffee spoon was wet; now it's dry.

 

Where is the water now?

CORRECT ANSWER
In the air
EDDIE SAYS
It's logical, isn't it? The spoon was wet, now it's dry. There's only one place the water could possibly be - in the air, having evaporated (into water vapour) away.
  • Question 12

Oscar's dad has been working in the garden.  He has been digging the ground to make a new vegetable bed.

 

Digging

 

He finds that there are a lot of rocks and stones in the soil.

 

What is the best method for removing them to leave a fine soil?

CORRECT ANSWER
Use a sieve
EDDIE SAYS
Can you imagine picking all the stones out, one by one? That's not going to happen! No, the best tool for the job is a soil sieve. The big stones, etc. cannot fit through the holes, get trapped and the fine soil tumbles through. It'll still take a while, though...
  • Question 13

Dad's digging reveals a number of animals that live in the soil.

 

From this list of animals, pick out the ones that you think Oscar's dad may have found living in the soil.

CORRECT ANSWER
Earthworm
Beetle
Millipede
Woodlice
Slug
EDDIE SAYS
Well, rabbits and mice live in holes in the ground, but is dad likely to be digging them up? Don't think so! No, it's animals like worms, beetles and woodlice that are common finds while digging. Having said that, the vast majority of soil animals are really tiny and you're going to need a microscope to see them.
  • Question 14

From the evidence in the previous questions, which sort of soil do you think is in Oscar's garden?

CORRECT ANSWER
Gravelly soil
EDDIE SAYS
If it was a clay soil it would be heavy and thick, with few stones and little opportunity to use a sieve. A sandy soil won't be full of stones and rocks, so a gravelly soil seems the best bet. They drain well, but it's hard work removing the bigger items to make working the soil easier.
  • Question 15

There are many plants and animals living in the soil.

 

Select factors from this soil list that you think they need to survive.

CORRECT ANSWER
Air
Water
EDDIE SAYS
Plants and animals are going to need air and water, aren't they? Both need oxygen from the air and both need water for their life systems to operate properly.
  • Question 16

In their garden is an apple tree.

 

Apple tree

 

Fill in the blanks in this sentence.

CORRECT ANSWER
EDDIE SAYS
The soil provides firm anchorage for the tree - the branches are going to be heavy and when the wind blows it doesn't want to be blown over. In addition, in the soil are all sorts of vital nutrients (like minerals) that the tree needs for its growth and normal functions. Of course, water is vital for all its operational systems.
  • Question 17

Oscar goes into the garden shed to collect some tools to help with the gardening.

 

Shed

 

The shed is made of wooden planks, it has two windows made of glass and there is roofing felt on the roof.

 

Complete the chart to show the properties each material has which make it suitable for the task.

CORRECT ANSWER
 TransparentWaterproofFlexible
Wooden planks
Roofing felt
Glass
EDDIE SAYS
Deciding on which material to use can be tricky. Take the windows: transparent and waterproof are important, but glass is fragile. However, it's cheap, so it may be the best material for the job. These are the sort of decisions you have to make when choosing what's best for a job.
  • Question 18

Leaning up against the side of the shed are two wheelbarrows, one made of steel and one made of plastic.

 

Wheelbarrow

 

Choose properties which the materials in these wheelbarrows will have.

 

 

CORRECT ANSWER
 Steel wheelbarrowPlastic wheelbarrow
Light (ie. not heavy)
Easy to mould
Goes rusty
Can split or tear
EDDIE SAYS
It's always a bit of a trade-off in terms of properties as to which is best. Take wheelbarrows: steel is a strong material but it will go rusty in time and it's quite heavy. On the other hand, plastic is light, cheap and easy to mould, but it's softer and more likely to crack or tear. Which one would you choose for moving rocks and bricks? What about piles of leaves?
  • Question 19

In the garden shed are many different gardening tools, all made from a variety of materials.

 

Can you sort them out, according to what they're likely to be made from?

CORRECT ANSWER
 PlasticMetalWood
Hosepipe
Nails
Football
Fence posts
Work helmet
EDDIE SAYS
Once again, it's choosing the best material for the job according to its properties. Take a football - wooden football? Metal football? Not likely! Nails - they've got to be really strong in a small package, so a strong metal like steel is the answer.
  • Question 20

Oscar's brother, Marcus, is making some fudge in the kitchen.

 

Saucepan with melting butter

 

Fudge reaches its setting point at 115 oC.  After this, the heat should be turned off.

 

Use this graph to determine how long Marcus will have to wait for the fudge to reach its setting point.

 

#8795 q20

CORRECT ANSWER
EDDIE SAYS
Can you read graphs OK? It's one of those key skills you need! First off, you need to know the setting point: 115 oC. To find how long Marcus will have wait, find 115 (just below 120) on the temperature scale (y axis), and go across the graph until you reach the curved line. Then read down from that point on the line to find how many minutes that is. Read that on the x axis (for time). It's 8 minutes.
  • Question 21

Unfortunately, Marcus is distracted by using his smartphone.

 

He leaves the fudge mixture to heat for 12 minutes.

 

What temperature will it have reached now?

 

#8795 q20

CORRECT ANSWER
EDDIE SAYS
Similar task to the previous question. Find 12 minutes on the time axis (x axis). Then go up to the curved line. Slide across to the y axis (temp. scale) and read off the temperature. It's just above 140 oC. In fact it's 142 oC.
  • Question 22

Do you think that Marcus can retrieve the situation, by allowing the mixture to cool back to 115oC, and then pouring it out to make yummy fudge?

 

#8795 q20

CORRECT ANSWER
No - it's irreversible and he'll end up with burned sugar
EDDIE SAYS
In fact, the clue is in the graph. Do you see that the line flattens out for the last three minutes - that it doesn't get any hotter? That means that the mixture has reached its boiling point. That means that the mixture is past its setting point, is now boiling sugar, and if Marcus cools it down he'll simply end up with a tray of brown goo. Not fudge. What a waste!
