Write your INDEPENDENT VARIABLE here
1. Draw and label your axes (like the diagram above)
2. Write the numbers on your axes. Make sure the
gaps between numbers is always the same
3. Plot your points (as crosses). Remember: Along the
corridor, up the stairs
4. Draw a Line of Best Fit

Write your INDEPENDENT VARIABLE here
1. Draw and label your axes (like the diagram above)
2. Write the numbers and labels on your axes. Make
sure the gaps are all the same size
3. Draw the bars at the correct height. Make sure
the bars are all the same width
4. Label the bars
Start the line at 0. Draw a straight line that goes through as many points as you can. Make sure
that all of the points are near the line of best fit.
There are three different types of average we can
do:
Mode: This is the most popular number.
For example: 1, 2, 2, 3, 3, 3, 3, 3, 4, 5, 5. In this list,
there are more 3s than any other number. So the
mode is 3.
Median: This is the number in the middle.
Put all of your numbers in order and find the one
in the middle.
For example: 1, 2, 2, 3, 3, 3, 3, 3, 4, 5, 5. The
number in the middle is the purple 3. So, the
median is 3.
Mean: Add up all of the numbers. Then divide
your answer by how many numbers you have.
For example: 4, 5, 6.
Add up the numbers: 4 + 5 + 6 = 15
There are three numbers, so divide your answer
by 3.
15 ÷ 3 = 5
The mean is 5.
In science, we convert between different
numbers to make it simpler to find answers
to equations. Here are some very common
conversions.
Kilo means a thousand. So saying 1
kilogram is the same as saying 1 thousand
grams.
1 kg
=
1000 g
=
1 x 103 g
1 km
=
1000 m
=
1 x 103 m
1m
=
100 cm
1m
=
1000 mm
=
1 x 10-3 m
1 cm
=
10 mm
1 mm
=
0.001 m
1 μm
=
0.000001 m
=
1 x 10-6 m
1 nm
= 0.000000001 m
=
1 x 10-9 m
If you see a number with x103 after it, move
the decimal place to the right 3 times.
For example:
5 x103 = 5000 Or 7.2 x103 = 7200
speed = distance ÷ time
We can write this in symbols:
s=d÷t
We can also put it into an equation triangle, like
the one below
This line
This line
means divide
d
means
times by
s
t
If you are trying to find the distance, cover up
this box.
s
t
You have this left:
So: distance = speed x time
If you see a number with x10-3 after it, move
the decimal point to the left 3 times
For example:
5 x10-3 = 0.005 Or 7.2 x10-3 = 0.0072
