Lets see if we can try to
explain the words, observation, inference, hypothesis.
An observation is something that you notice using any of your senses.
For example:
- We see that most cars are red.
- Smelling deodorant on Jonathon.
- Hearing a dog barking next door.
From the observations above we can infer that:
- The car factory always runs out of all other paints except red.
- Jonathon forgot to shower after gym class.
- There must be a cat next door.
We can formulate the likely
hypothesis from the observations above:
- Red is a popular colour amongst car buyers. (This can be tested by
a survey)
- Deodorant smells more on a hot day than on a cold day.
- Dogs bark more when they are hungry.
Let's perform some unbelievable magic. You must observe closely and write down your observations.
Go to the first magic demonstration this worksheet also asks you to identify and draw scientific equipment.
