Topic A: Waste and Our World
Students learn about wastes produced through natural processes and human technology. In studying natural systems, students learn that all plants, animals & other living things are made up of materials that recycled through the environment & used again & again.
In studying human concumption and wastes, students identify wastes produced within their community and learn the methods used for disposal.
Students learn that some waste is biodegradable, some is reusable and that other wastes are toxic. They learn that personal action in reducing, reusing & recycling materials can help lessen the waste we accumulate.

Topic B: Wheels and Levers
Students apply simple techniques & tools to building vehicles and devices that move. In constructing these objects, students apply previous learnings about structures and explore new applications with wheels, rollers, gears, pulleys and a variety of levers and connectors.
Students learn that different forms of energy can be used to propel their model devices: direct push; stored energy from a compressed spring or falling weight; battery.
On completing their projects, students learn to EVALUATE their work - including the effectiveness of the vehicle or device and the selection of materials.
There are some technical terms to read here in the Glossary . . . .
Topic C: Building Devices and Vehicles that Move
Students learn about basic components of simple machines: how they are assembled, how they operate and how they are used. They explore different techniques that can be used to transfer motion from one component to another, using simple connectors & various levers, gears, pulleys & band driven systems.
As they work with these components, students learn the functions that each can perform, including sample applications and ways for them to be used in a larger system. Finally, students explore how these simple machines can be used to change the speed or force of movement.

Topic D: Light and Shadows
Students learn about light by studying the effects of light on things within their environment. They learn about light sources, about materials that light can pass through and about what happens when a material blocks or changes the path of light.
By observing shadows and their motions relative to a light source, students discover that light & shadows fall along a predictable path. Students discover that mirrors, prisms and a variety of other materials can affect the path of light through reflection & refraction.

Topic E: Plant Growth and Changes
Students learn about the structure and growth of plants by raising plants in the classroom and by observing plant growth within the community. They learn to recognize and describe different forms of leaves, stems, roots & flowers and learn their functions in supporting growth and reproduction.
Students learn various ways of starting new plants and what the plants' requirements for growth are. By studying a variety of plants, students learn that different plants have different needs. Students gain this knowledge through the experience of caring for plants.
