What makes a good fuel?What makes a good fuel?
• Demo burning of three different types of fuels:-– Wood Shavings,– Small pieces of paper,– Bunsen burner
• Discuss which fuel is best? What makes a good fuel?
• How could you find out which fuel is best?

• A variable is something we can change in an experiment.
• On your post it notes write down as many different variables with this experiment as you can think of.
• On your poster draw the table below:-

How can we ensure our How can we ensure our experiment is repeatable and experiment is repeatable and
valid?valid?
• Repeatability:- • To ensure an experiment is repeatable
you should repeat the experiment at least 3 times ensuring your results are similar each time.
• Validity:- • We can ensure our experiment is Valid by
ensuring we only change the IV in the experiment and that all other variables are kept constant.

• Add up your 3 readings for Change in Temperature and divide by 3.
• Draw an appropriate graph to show your results.
• Remember if both your variables (IV and DV) are numbers then you should draw a line graph otherwise draw a bar graph.
