Children in Year 4 took part in a wide variety of experiments for National Science Week this year. Some of these included:
* Observing what happened when raisins were dropped into lemonade
* Making 'Flubber'
* Conducting a fair test
For the fair test, children decided to follow our 'Angry Birds' topic by testing if the weight of a material affected how far an object (the 'birds') travelled when propelled from a catapult.
Children developed their scientific skills for this experiment by creating their own model catapults for testing purposes. They also used a variety of other skills throughout the experiment, including:
* Weighing materials with accuracy
* Changing the independent variables (the materials)
* Keeping the controlled variables the same (how far the catapult was pulled back, keeping the catapult in the same place, etc)
* Measuring accurately with metre sticks and rulers
* Repeating the experiment to check for inconsistencies
* Working out averages with calculators
* Recording data
* Creating graphs
* Analysing their data
* Working as a team
The children discovered that the lightest material travelled the furthest distance and the heaviest material travelled the shortest distance.
Please take a look at our experiment below to see how we put these skills into practice:
