Hi Investigators
Thanks for doing all those tests. Just finished this advert for the new toothpaste.
The boss says that we should make sure it is the best toothpaste before we put
the ad on TV. Can you help us?
Thanks,
Sales Team, Bright Smile Toothpaste Company

Resources
To do these tests you will need:
What did you find out?
 Which toothpastes performed well in your tests?
 How do they compare to the toothpaste that you
made?
 Do you think any of the toothpastes could be
improved in any way? Why do you think this?

At
least 3 different brands of
toothpaste for comparison

Spare
clean toothbrushes

White
tiles or old plates

Permanent
markers or shoe
polish

Additional
plastic containers
and/or plates

Covering
for the table
Now carry out a survey to find out which
toothpastes your friends and family prefer.
There are ideas on the back to help you.
H
ow many people will you ask?
W
hat do you want to find out?
When you have finished the survey you can:
m
ake a block graph to show what people think
u
se the results from your tests to find out if people’s
favourite toothpastes are good at cleaning teeth
d
ecide if one of the toothpastes is better than the others.
Sharing your ideas
One way to share your ideas is to create a winners’
podium of different brands. You may prefer to
produce a grid or spreadsheet of your results.
Note keeping
You could use a grid like this one or you might
think up a better way to make a record.

Don’t know what to do?
Here are some ideas to help you:
Comparing
toothpastes
´ ´
 I think we should use some of the investigations that we
carried out when we made our own toothpaste.
´ ´
´ ´
´ ´
´ ´
 I think´we could
´ find out how much foam
the toothpastes produce. Some people may
not like too much foam.
´ ´
´
´ ´
´
 We could find out if using different amounts of´
toothpaste makes a difference.
´
What will you do?
Carrying out a survey
Here are some questions we are going to ask people about
our toothpastes.
 Do you like the smell of any of these toothpastes?
 Do you like the colour of any of these toothpastes?
 Do you use one of these toothpastes? If so, why do you use that one?
 Do you use a different toothpaste from these? Why do you use that one?
Can you think of any more questions to ask?
