Lesson plan about structures that span over space
Subject: Science/Engineering
Grade Level: 3-5
Lesson Objective: Students will be able to identify different types of structures that span over space, such as bridges and buildings, and understand the principles of how they are designed and built.
Materials needed: pictures of various types of structures (bridges, buildings, towers), construction paper, craft sticks, glue, tape, rulers, scissors
Procedure:
1. Introduce the lesson by showing students pictures of different types of structures that span over space, such as bridges, buildings, towers, etc. Ask students to identify the different types of structures and discuss their purposes.
2. Discuss with students the principles of how these structures are designed and built, such as the use of supports, beams, arches, etc. Explain that engineers use these principles to design safe and efficient structures that can span long distances.
3. Divide students into small groups and give each group construction paper, craft sticks, glue, tape, rulers, and scissors. Instruct them to work together to design and build their own structure that spans over space, using the materials provided.
4. After the groups have completed their structures, have them present their designs to the class. Encourage them to explain how their structure works and why they designed it the way they did.
5. Discuss with the class how different types of structures are used in the real world to span over space, such as bridges for crossing rivers or buildings for providing shelter. Ask students to think about how these structures impact their daily lives.
6. To wrap up the lesson, have students reflect on what they learned about structures that span over space. Ask them to discuss the importance of engineering and design in creating safe and efficient structures for people to use.
Assessment: Observe students during the construction of their structures to assess their understanding of the principles of how structures span over space. Evaluate their presentations and reflections to gauge their comprehension of the lesson.
