Prediction
Contents
Key Stage 2
Meaning
A predication is when you say what you think will happen in an experiment or investigation based on your understanding or on the results of another experiment.
About Predictions
- A prediction can be made before an experiment using your understanding. If you compared how far a ball rolls on a sticky floor and a smooth floor you could make a prediction before you did the experiment and say; The ball will roll further on the smooth floor than the sticky floor because things get stuck on sticky floors.
- A prediction can be made using the results of your own experiment. If you find most people in your class have brown eyes you might predict most people in another class will also have brown eyes because brown eyes is the most common colour.
- Your prediction may be wrong, and that's ok. Science is most interesting when unusual things happen and our predictions are wrong because then we can learn new things about the world.
Key Stage 3
A prediction is when a scientist uses a hypothesis to suggest what the results of an experiment might be before performing it.
About Predictions
- A prediction may be based on a previous observation or on the results of other experiments or investigations.
- A prediction should be based on scientific ideas and not just a guess.
- The results of one experiment can be used to predict the results of another experiment.
- A hypothesis often provides a prediction for an experiment as experiments are usually designed to prove a hypothesis to be incorrect if possible.
