The Grade 3’s have designed a Science experiment to see which surface material will make a plasticine ball ‘splat’ the most.\u00c2\u00a0 After making their predictions, they set off in pairs to see if they could set up a ‘fair test’ using the equipment they were given.\u00c2\u00a0 To insure that their experiment was a fair test, they knew that they must change only one factor at a time while keeping all other conditions the same.<\/p>\n

Scientists call the changing factors in an experiment variables.\u00c2\u00a0 The different surface materials needed to be the only changing variable, everything else needed to stay the same.<\/p>\n

\n“Is this a ‘fair test’? Maybe we should measure the height we drop the plasticine on each surface and keep this the same each time?”<\/p>\n

\"g3-science-14-05-09-305\"<\/p>\n

“Yes a good idea, that way we keep that variable the same”,<\/p>\n

\"g3-science-13-05-09\"<\/p>\n

“Shall we make lots of different plasticine balls to drop on the different surfaces?\u00c2\u00a0 No, we need to use the same amount of plasticine each time so this variable stays the same?”<\/p>\n

“Will you draw around the ‘splat’ or shall I?”<\/p>\n

\nHere they are discussing their results.\u00c2\u00a0 They had to record their results by drawing around the ‘splat’ on centimetre squared paper.\u00c2\u00a0 To find out the area of each ‘splat’ they counted the amount of squares each ‘splat’ covered.\u00c2\u00a0 At first, they were not sure whether to count the squares which were only a half or a quarter covered.\u00c2\u00a0 In the end, they decided to use\u00c2\u00a0 their skills of adding fractions and rounded up to the nearest whole square covered.<\/p>\n

Great science work, Grade 3!\u00c2\u00a0 You all showed that you understood the importance of creating a fair test.\u00c2\u00a0 Did your predictions match your results?<\/p>\n","protected":false},"excerpt":{"rendered":"
