Task Sheet 1 (Bronze Challenge): Laboratory Safety Rules and Equipment
1.
List three laboratory safety rules:
i. …………………………………………………………………………………………………………………………………
ii. …………………………………………………………………………………………………………………………………
iii. …………………………………………………………………………………………………………………………………
2. Use the words in the box to fill in the gaps in the following sentences.
a.
We use a ___________________________ to measure volumes of liquid.
b. We use an __________________________ to measure the mass of solids.
c.
We use a ___________________________ to measure temperature.
d. We use a ___________________________ to measure forces.
e. We use a ___________________________ to measure time.
f.
We use a ___________________________ to measure lengths.
electronic balance
metre rule
Newton meter
measuring cylinder
stopwatch
thermometer
3. Choose the correct words to complete the paragraph below.
When we light a Bunsen burner the air hole should be ______________ (open / closed).
The flame is hottest when the air hole is _____________ (open / closed), this is called
the ______________ (safety / roaring) flame and is _____________ (blue / yellow).
We can control the size of the flame using the __________________ (gas tap / collar).

Task Sheet 2 (Bronze Challenge): Variables in an Investigation
1.
In a scientific investigation the things that change or could be changed are called
variables; you may have called them factors at Key Stage 2.
Draw one line from each type of variable to its description.
Independent variable
A variable that must be kept the same to
make the investigation a fair test.
Dependent variable
The variable that you deliberately change
or choose the values of in an investigation.
Control variable
The variable that changes each time you
change another variable. You measure this
variable during the investigation.
2. A scientist investigated how fast different animals can run. She chose five different
animals and measured the time it took each one to run 100m.
Draw one line from each of the variables in the scientist’s investigation to the type of
variable it is.
In each test she kept the distance the
animal had to run the same (100m).
In each test she measured the time
taken for the animal to run 100m.
In each test she changed the type of
animal that was running.
Independent variable
Dependent variable
Control variable
3. In an investigation there are two types of data (measurements) that you might collect;
continuous data and categoric data.
Draw one line from each type of data to its description.
Continuous data
Data that can have any numerical (number) value.
Categoric data
Data that can be sorted into groups with word labels.

Task Sheet 3 (Bronze Challenge): Drawing Bar Charts
In Science we draw bar charts or line graphs to display the data collected in an investigation.
We draw a bar chart if the data is categoric and a line graph if the data is continuous.
Type of animal
Time taken to run 100m / s
Cheetah
3
Wildebeest
4.5
Zebra
5.5
Lion
4.5
Elephant
9
Draw a bar chart of the data above.

Task Sheet 4 (Silver Challenge): Laboratory Safety Rules Poster
For this task you will need to produce a poster about one of the
laboratory safety rules that you have learnt in your Science lessons.
Your poster should be eye-catching and colourful. It should make the
safety rule very clear and explain why the rule is important. As this
is a poster you will need to limit amount of writing you include; so it
would be useful to use pictures to get your point across. For
example, you might draw one student following the rule and so staying
safe and another not following the rule so putting themselves in
danger.
Your poster can be hand drawn or produced using a computer.
Task Sheet 5 (Silver Challenge): Bunsen Burner
Instruction Leaflet
For this task you will need to produce a leaflet describing and
explaining how to use a Bunsen burner.
Your leaflet should include step by step instructions explaining how to
use a Bunsen burner. It would be useful to include pictures as well as
a written description of each step.
Your leaflet can be hand drawn or produced using a computer.

Task Sheet 6 (Gold Challenge): Who was Robert Bunsen?
Robert Bunsen was, fairly obviously, the inventor of the Bunsen
burner! However this is not all he did. Your task is to research
Robert Bunsen; you will need to find out as much as you can about him
and present the information in a factsheet or biography. For
example:
 When did he live?
 Where did he live?
 What was his job?
 What did he discover or invent?
 Did he work with any other famous scientists?
 Why is his work still important today?
You will find plenty of useful information on the internet but you
must not just copy and paste it into your final piece of work! You will
need to find several useful websites and read the information
carefully – it might help to make some rough notes of the interesting
or useful facts as you are reading through. You should then write the
information onto your factsheet or biography in your own words. It
would be helpful to include some images, for example a photograph of
Robert Bunsen.
You may produce your factsheet or biography by hand or using a
computer.
