CeriaLearnSJKC Science practice: observe, compare and explain
Help your child separate what they can observe from what they think caused it. These examples introduce careful descriptions and fair comparisons without needing special equipment.

Describe the observation first
Ask what was seen, heard or measured. “The ice became smaller” is an observation; an explanation says why it happened. Keep the two separate so that a good guess is not mistaken for evidence.
Change one thing in a comparison
When comparing conditions, discuss what changes and what should stay the same. If both the amount of water and the sunlight change, it is harder to know which explains the result. A single observation may not settle a question.
Use a reason connected to the evidence
A science answer should connect the result with an explanation. Ask “What makes you think that?” Accept a careful description of uncertainty instead of forcing a confident answer without evidence.
Try these examples together
An ice cube is left in a bowl at room temperature. Later there is liquid water in the bowl. What change happened?
Answer and explanation: The ice melted: solid water changed into liquid water. “There is liquid water in the bowl” is the observation. The ice gained heat from its surroundings.
To compare how light affects two similar plants, one is placed near a window and one in a dark cupboard. What should be kept similar?
Answer and explanation: Keep factors such as plant type, starting size, soil, water and observation period similar. Light is the intended difference. Other differences, such as temperature, can still affect results, so interpret the comparison carefully.
