How can we measure lung capacity in science next week? What data would we need to collect to make a bar chart, a line graph or a scatter graph? Would it be appropriate to make a pie chart? by Year 6 Teacher

We can set obstacle course and every minute we can count how many beats per min at rest and after the course.We will need :

Stop watch and a ballon.

We need a balloon because before the obstacle course we are going to measure how much we can blow in 1 breath.and the same thing after the course.

We can measure lung capacity by looking at how long we can breath out. We have to collect the seconds we can breath out (continued) and put it into a bar chart. We think a scatter graph will be appropriate because then we can see if the seconds of how long we can breath out increase or decrease. We will need balloons and a stopwatch. This is the method: we put a balloon on our mouths and start blowing in it for as long as we can and someone can time us. Then we should have 2 measurements (the time and the balloons circumference) So one of those measurements will be the x axis of the scattergraph and the other one the y axis.

We could measure lung capacity in swimming or PE then we could collect all the data and use it in maths by putting it into a line graph or a bar chart or pie chart...The equipment that we are going to use: Stop watch, ballon rulers...

Ines: We could run around the pitch 5 times

Maria: we could measure our lung capacity

We could measure lung capacity by exercising for 1minute and see if it increases, or blow a balloon for a long time until you can't blow anymore, and measure how big is the balloon, and see who's balloon is bigger by making a line graph

We could measure lung capacity at rest and then do a lot of exercise like jumping, swimming and then see if it has increased after exercising. If we put the results on a line graph it's better because it's more accurate

We would have to take a balloon and blow in it for a limited time (to make it a fair test) and then measure the axis using measuring tape and then turn the results into a bar graph using the other peoples' results and compare them with your results. To use a scatter graph, we need two kinds of data like a diameter of axis and measure it again or try to turn the tape around and then measure it.

It could be appropriate to make a scatter graph, but it's better to make a bar chart.

A scatter graph is sort of hard to understand.

We could measure our lung capacity by doing this experiment.

We can get a balloon and then blow.
