Lutsel K'e Dene School Lesson Plan: Resources

The document provides a lesson plan for a Grade 4 elementary science class in Lutsel K'e Dene School. The students will work in groups to build bridges out of straws and tape that can support different loads. Over the past two weeks, the students have been learning about structures and forces through other building activities, research, and a video. They will now design and construct their bridges, which will be judged the next day on how much weight they can hold. The lesson aims to teach the students about important load-bearing concepts and collaborative work.

Lutsel Ke Dene School Lesson Plan

Gr. 4 Elementary Science - Structures & Mechanisms Teacher: Ms. Debra Bridgman, Gr. 4,5,6 Lutsel Ke Dene School Building a Bridge Structure - Load Bearing!! General and Specific LOs: (NWT K-6 Science & Technology) Overview As students continue to design and build mechanical devices and structures, they develop a more sophisticated understanding of forces. Students in Grade 5 will identify the forces acting on and within structures, and will give simple quantitative descriptions of these forces. They will focus on ways of making mechanisms accomplish specific tasks with less effort. Big Idea Forces will affect different structures and devices in different ways. Demonstrate an understanding of the effect of forces acting on different structures and mechanisms; Design and make load-bearing structures and different mechanisms, and investigate the forces acting on them; and Evaluate the design of systems that include structures and mechanisms, and identify modifications to improve their effectiveness. Specific Objectives & Context: Specific Learning Outcomes Understanding Basic Concepts. Students will: Identify and measure forces acting on a structure (e.g., mass, air pressure), and describe the effects of their application; Identify the parts of a structure that are under tension and those that are under compression when subjected to a load (e.g., the wires in a suspension bridge are under tension; a ladder bearing a mass is under compression) *Design and make a frame structure that can support a load (e.g., a bridge); *Communicate the procedures and results of investigations for specific purposes and to specific audiences, using electronic media, written notes and descriptions, drawings, charts, and oral presentations (e.g., give a presentation on the process of designing and making a specific structure) Students have been working on the unit for two weeks, have built other structures with guidance, done research. Essential Question: What are the important things to remember if you want to make a strong bridge? Engage and question with group brainstorm re concepts that students have worked on over the past two weeks. Local example of bridges materials, purpose, what do they have to carry or support? Focus for bill Nye video on Structures. Teacher think aloud about important concepts in structures and in bridge building. Students participate and record ideas on board with teacher. Procedure: Group Construction Expectations build bridge in one afternoon; will be judged by community members on load it can hold tomorrow; materials, time frame choose groups, planning and feedback, do it. Bridge needs to span a minimum of one foot.

Resources: Student groups will get same number of straws and tape.

Activity: Groups gather materials. Locate their space, diagram and discuss design, ask for any feedback they need, carry our construction.

Judging : Community members join the class the following afternoon to test the bridges for load bearing capacity, talk to the young designers, and give out prizes. Reflection: Students look at winning designs and suggest what made them the best designs. They reflect on their experience how did their group work, was the design a collaborative effort or not. Why is designing a good bridge important?? Evaluate: Rubric on group activity and presentation and peer revue. Ability of students to communicate important concepts and explain how they approached their design.
