Lesson details
Key learning points
- Scientists take, repeat and compare measurements using a range of scientific equipment.
- The evaluation of an investigation can include an explanation of, and degree of trust in, the results.
- Greater surface area on a moving object can increase water resistance.
Keywords
Water resistance - Water resistance is a type of friction force which acts between water and the surface of an object.
Trust - How reliable we think the results of an investigation are.
Reliable - If a result is reliable, it measures something consistently.
Evaluation - In the evaluation of an investigation, scientists judge how reliable the results and conclusion are.
Common misconception
All objects experience the same amount of water resistance, regardless of their size or shape.
Discussion and explicit teaching. The investigation they carry out will show them that this is not true.
