- We can make predictions to share our scientific ideas about what we think will happen or how something might work.
- Scientists make careful observations to answer questions.
- Soils are a combination of different things, including rock, organic matter and air.
Common misconception
Children may think that soil is any dirt on the ground, or that soil was created when Earth was created. They may also think that plants make soil.
The activity to separate layers of soil in water allows children to make their own observations of what soil is made from.
