Making it a FairCompetition Review with thechn how to make an investigation fair key point is that you haveto keep something the same and change just one thing at a time.Remind them of the ramp exercise. Good way is to have every childin the small group do a different change, thus making it fair.Discuss it now in terms of it being a competition between the chnin the group. In this way they will get an understanding of how ithas become fair.
Chn are to workin Literacy groups. They will have a large sheet of paper with atable prepared for them. They are to consider the question seeSkill Activity 10 sheet with examples. They are to decide which oneaspect they are going to change in order to keep the test fair andthen decide on the factors they will each take control of.
Share some of thetables the chn have created and discuss.

Deliberatelymaking it unfair Do a demo whereI purposefully make things unfair. Use example on Skill Activity 11 Which dissolves first, soft brown sugar or granulated whitesugar? Ask the chn to call out the words Thats not fair!whenever they spot you going wrong. When they identify somethingunfair, ask a selected child to explain why its not fair. Chn areto discuss their reasons with a partner and then feed back to thewhole class.

Fairtesting Demo to the chnusing a small Orange squash ice block and a larger water ice block.Show them to the chn and put the orange one near the radiator andthe water one on the table. Am I being fair? I wont change the iceblocks but should everything else be the same for each? Yes.Because we only have one thing different in aninvestigation, that is our one difference. Show the chn a blown upversion of the top half of Skill Activity sheet 12. They shouldalready have spotted 2 unfair things. Diff size blocks and theradiator factors.

Stop! Explain to thechn that we always have to consider how to do things safely. Theycan cause huge risks to themselves and others when doing practicalwork. Teachers are always around to look after them but they needto be aware of the possible dangers. Show chn on the board adifferent danger to those on the sheet and discuss and show themhow to record.
