Children are natural scientist, they. Children learn by experiencing the world around them. Unschoolers are firm believers that children learn when they are let to explore the world on their own. This is true for any type of schooler. Children and scientist do a lot of the same things.
- watching = observing
- playing = experiment
- change something = modify the experiment
- telling others what they have done = record results.
This is equivalent to Physical Science. Learning about matter and materials, light energy lesson along with force and motion lesson are just some of the subjects that can be introduced at a young age in elementary.
