Grade 4: Can you Balance
Unit Description
Students will artfully explore balanced and unbalanced forces by creating a Calder mobile, constructing a Rube Goldberg Machine, and creating an entrepreneurial presentation to pitch their creation for purchase. Students will unleash creativity, sharpen their critical thinking skills, while applying their scientific understanding of force and motion.
Unit Essential Question
How can exploring balanced and unbalanced forces help us to understand cause and effect and change in our world?
Real World Context
Students studying about balanced and unbalanced forces can understand the mechanics of the world around them. When objects are balanced, they are still, whereas, when forces are unbalanced the object is moving. They are able to understand how certain materials interact with one another to create movement.
Cross-Cutting Interdisciplinary Concepts

Cause/Effect
Change

Projects
Project 1: Balancing Act: Calder Mobile
In this project, students will use their knowledge of balance and unbalanced forces to design and create a Calder mobile. A Calder mobile is a mobile of 3 to 5 levels that has various materials attached to wire, that must be balanced upon completion. The material used to balance must be of various sizes including materials such as foam pieces, card stock, wire, string, paper clips, and/or beads. In completing this project, students will be using their critical thinking skills to utilize the materials to create a piece of artwork that incorporates the scientific concepts of gravitational forces, as well as balanced and unbalanced forces. Students will also write about their experience before, during, and after completion of the project.
Project 2: Goldberg’s Not-So-Simple Machine
In this project, students will engage in the design process around an exciting 4th grade science topic: Force & Motion! Students will create a drawing of a Goldberg Not-So-Simple-Machine and create a kinetic sculpture, or working model, of that machine. In this project, students will demonstrate how simple machines can be combined in a complicated way to perform a simple task.
Project 3: It’s Showtime!
In this project, students will have to first complete Project 2 in this 4th grade unit. In Project 2, they constructed a Rube Goldberg machine, using a set of simple machines that work together to comprise a complex machine with a specific function. In this particular project, students will be taking their hard work in the design studio and work on marketing it to an audience! Students will work collaboratively to write a persuasive script utilizing dialogue to clearly define a problem that their simple machine will solve. The purpose of the script is to persuade the audience to purchase their invention. Finally, it’s showtime and students will perform their script and skit!
Project Essential Questions
PROJECT 1:
- How can gravitational forces affect the balance of objects?
- How does proportion affect balance?
PROJECT 2:
- How do balanced and unbalanced forces relate to simple machines?
- How can simple machines combine to affect the balance of forces?
- How can simple machines combine to affect motion?
- How can simple machines make a task easier/harder?
- How do we sometimes make things more complicated than they need to be?
PROJECT 3:
- How can I use a persuasive, strong voice to express my knowledge of simple machines?
