Question

A learning aid to create awareness about the relative size of planets :

• A. Marble, ball etc.
• B. Pictures of planets
• C. Picture of solar system
• D. Video presentation

Answer 1

Answer:

A. Marble, ball etc.

• 3D Experience & Hands-on Learning: Images and (2D) videos only provide visual experience to children. However, when using three-dimensional (3D) objects such as goalies and balls of various sizes, the child clearly understands the relative size difference of the planets and their extent by handling them (Hands-on experience).

• From Abstract to Concrete Learning: Science teaching method In science, children learn most effectively by touching and seeing (Concrete objects) at the primary/upper primary stages.

• For example: When comparing a large basketball to represent Jupiter, a small goalie to represent Earth, and a mustard seed to Mercury, their size ratio (Relative scale) makes them more clear to children.
