Lesson details
Key learning points
- Scientists make observations and measurements to help them to learn more about the world and how things work.
- Scientists review the results they have collected to decide what happened and explain what they have found out.
- We can use words ending in -er to explain how one thing affects another thing.
- When the object is closer to the light source, it blocks more light and this makes the shadow appear bigger.
Keywords
