Objective
By the end of this lesson, you will be able to understand and apply basic physics concepts using Lego bricks.
Materials and Prep
- Lego bricks of various sizes and shapes
- A flat surface to build on
- A ruler
- A stopwatch or timer
Prior knowledge of basic Lego building techniques is helpful but not required.
Activities
- Build a Lego tower: Start by building a tower using Lego bricks. Experiment with different heights and widths. Observe how the tower stands and how stable it is.
- Test tower stability: Use the ruler to measure the height of your tower. Then, gently push the tower from different sides to see if it remains standing or falls. Record your observations.
- Build a Lego bridge: Using the same Lego bricks, construct a bridge between two supports. Test the strength of your bridge by placing small objects on top of it. Observe if the bridge holds or collapses.
- Measure and compare: Measure the length and width of your bridge using the ruler. Compare the measurements with the height of your tower. Discuss the differences and similarities between the two structures.
- Time for destruction: Challenge yourself to build a structure that can withstand the force of dropping a Lego brick from a certain height. Use the stopwatch or timer to measure how long your structure remains intact.
Fifth Grade Talking Points
- "Physics is the branch of science that deals with matter, energy, and the interactions between them."
- "When building a tower, it is important to distribute the weight evenly to maintain stability."
- "The height and width of a structure can affect its stability. Taller and narrower structures are usually less stable than shorter and wider ones."
- "Bridges need to be strong enough to support the weight placed on them. Different bridge designs can have different levels of strength."
- "Measuring the dimensions of structures helps us compare and analyze their characteristics."
- "Gravity is the force that pulls objects towards each other. It is what causes objects to fall."
- "When designing structures, engineers consider forces such as gravity and how materials will respond to those forces."
