The objective of this lesson is for children to design machines or vehicles to solve problems and to investigate how machines work together to complete a project
Hold up a couple of the LEGO® DUPLO® figures.
Tell the children that the city where the figures live has no outside places where children can play.
Explain that they are in desperate need of a new park but that building a new park is a big project.
Tell the children that the city needs help planning for this big project and talk to them about the
different pieces of equipment they would need for such a project (e.g., a digger to move and
flatten the ground or a wheelbarrow to haul smaller materials and debris).
Ask the children to build a piece of equipment to help with the park project.
Explain that they may use the building cards for inspiration, or design their own machine or vehicle.
Help the children as needed to attach some of the more difficult parts.
If a child finishes quickly ask them to build another piece of equipment, tell them that several
pieces of equipment are needed to complete the project.
Once the children have finished building, ask each child to share their model(s) with the group
and describe how it will help with the park building project.
Facilitate a discussion about the children’s models.
Ask questions like:
- Which part of the project would your piece of equipment help with?
- Would it be used during the whole project or only for part of it? Why?
Encourage the children to demonstrate how their piece of equipment would help with building the park.
Tell the children that the city wants to provide transportation so people can easily visit the new park.
Ask them to build a vehicle that can hold one or two passengers.
Have them demonstrate how the vehicle transports the passenger(s) to the park.
Did you notice?
Observing the following skills can help you monitor whether the children are developing the necessary competencies:
- Science - Using strategy and planning to solve problems
- Technology - Asking questions about technology-related concepts
- Engineering - Investigating, asking questions, making observations, and gathering information to inform the design of machines or tools
- Engineering - Participating in the engineering process by designing, building, and testing models
- Math - Using spatial awareness to understand objects and how they move
