Bridge Building

7th Grade Technology

  •  

    Overview:

    7th Grade Technology covers several units over 10 weeks. Initially, students develop an understanding of the basics of Technology, how it impacts our lives, and how it is created and used. The next unit of study is Technical Drawing. Students learn the basics of technical drawing and how to draw objects from both an isometric and an orthographic viewpoint. Students will work through a series of drawings and will gain an understanding of mathematical and technical concepts of creating such drawings. Next, students take this knowledge and apply it to design and create a bridge. The engineering unit begins with students learning principles of engineering, loads and forces on structures, and different types of bridge designs. Once students have designed their bridge, they will construct it out of balsa wood and test how much weight it can hold. Finally, students will complete a unit on Physics of a Catapult. We will cover the history of the catapult, how it has evolved, and the science behind how it works. Students will make small scale catapults and will test them for accuracy by "storming the castle" with pennies. Students will be required to calculate where their catapult should be placed and how fast the penny is being thrown.

    Expectations:

    It is expected that each student comes to class ready to learn and succeed. Students will need to be prepared each day with a pencil and a folder. It is expected that each student adheres to the safety requirements of the shop as well as the classroom rules and expectations.

    Grading:

    Students are graded equally among three areas: Tests/Projects, Classwork/Homework, and Participation. Participation is calculated daily, with each day being worth 3 points, and entered at the end of the week. With each section being weighted equally, it is important for students to perform well in all three areas.
