OBSERVATIONS vs INFERENCES

If I say the object is an apple…. this is an inference not an observation.

The observations would be

-spherical (about 5 cm diameter)

-mass about 150 g

- surface is waxy, can be punctured with fingernail

- colour is yellow patches with red streaks running vertically with some underlying orange tints

- Shriveled green leaf-like area in central disc  about 1 cm

in one end

- other end has a 2 cm, stick-like piece attached to main ball (green and brown)

Lab 1.1 Candles

Purpose – to learn how to make exact observations (not inferences) about a burning candle.

Experiment –

     Data – mass and height before and after burning

     Observations – about an unlit candle and about the burning                         process

Conclusion

     What inferences can you make based only on your experimental observations.
