3rd Grade Book List by Unit

Toys - Phenomenon Unit

How can we design fun moving toys that other kids can build and enjoy?

In this unit, students will engage with the question, How can we design fun moving toys that other kids can build? They will investigate the design of different moving toys to build our own toys. Students will explore everyday objects like toys, rockets, and cars to see how they move, change direction, and change speed as a result of an unbalanced (net) force applied to the object.  They will learn how different forces can cause toys to move in different ways. Students will apply the physics ideas to explain their toy design.

Marvelous Machines Making Work Easier- Engineering Unit

How can we use knowledge of simple machines and the Engineering design process to design and improve a factory subsystem that makes work easier?

In Marvelous Machines: Making Work Easier, students discover how engineers combine multiple simple machines to complete difficult tasks. The unit begins with the storybook Aisha Makes Work Easier, in which a girl named Aisha living in Massachusetts explores the field of Industrial Engineering to complete her summer project. Over the course of the unit, students investigate the different kinds of simple machines and their uses in industrial processes. Like Aisha, students then follow the steps of the Engineering Design Process to imagine, plan, create, and improve their own model of an industrial system that uses simple machines to make work easier.

Building Automated systems - (Computer Science extension for Marvelous Machines)

How can we create a computer automated system to make a home more safe or comfortable?

Students learn about computer-controlled automated systems through activities, discussions, and readings designed to make the computer science concepts relevant for this age group. Students use the Engineering Design Process to create an automated system of inputs and outputs to increase safety and/or efficiency in a home.

Hazardous Weather - Avalanche - Engineering Unit

How can we design an avalanche protection system that protects a village against an avalanche with snow and debris?

In this unit, students will use what they learn from designing barriers and catches to engineer an avalanche protection system. Students will explore the causes of avalanches, discover ways to stop falling objects and how barriers can be constructed. As the final project they will design and build and Avalanche protection system to protect a village.

How can we help the lost orca, Springer, survive and grow to be an adult whale?

The focal objectives for the unit revolve around understanding how Springer became lost, identifying her family, assessing her health, and returning her to her family. This learning will take place as students gather evidence, analyzing data, and engaging in discussion and scientific modeling around the central question, “What does Springer need to survive and grow to be an Adult Orca mother?” 

Birds - Phenomenon Units

How can we help the birds near our school grow up and thrive?

In this unit students will grapple with, How can we help the birds near our school grow up and thrive? Students will apply the following ideas to explain phenomena or design solutions to problems they experience in their environment: Organisms have characteristics, including traits, behaviors and life-cycle, that result from interactions with the environment and genetic materials being passed down from parents. Organisms with certain characteristics are better able to survive, reproduce, and cope with change in the environment than organisms that lack these characteristics.

Slick Solution - Cleaning Up Oil Spill - Engineering Unit

How can we use what we have learned about ecosystems, materials, and tools to help us design a process to clean an oil spin sot aht it has the lease impact on an ecosystem?

In A Slick Solution: Cleaning an Oil Spill, students explore how engineering helps to clean up pollution that threatens an ecosystem. The unit begins with the storybook Tehya’s Pollution Solution, in which a girl named Tehya, a member of the Lower Elwha Klallam tribe in Washington State, explores the field of Environmental Engineering in order to help clean up an oil spill in a local river. Over the course of the unit, students investigate methods to detect pollution and evaluate information about ecosystems. Like Tehya, students then follow the steps of the Engineering Design Process to imagine, plan, create, and improve their own oil spill cleanup process.
