In a class demonstration, students observe a simple water cycle model to better understand its role in pollutant transport. This activity shows one way in which pollution is affected by the water cycle; it simulates a point source of pollution in a lake and the resulting environmental consequences.

In this lesson the students will explore the outdoor classroom looking for examples of natural resources used to make useful products with a special emphasis on how rocks and soil (clay) are used.

The purpose of this activity is to demonstrate Newton's third law of motion which states that every action has an equal and opposite reaction through a small wooden car. The Newton cars show how action/reaction works and how the mass of a moving object affects the acceleration and force of the system. Subsequently, the Newton cars provide students with an excellent analogy for how rockets actually work.

Students explore the causes and effects of the Earth's ozone holes through discussion and an interactive simulation. In an associated literacy activity, students learn how to tell a story in order to make a complex topic (such as global warming or ozone holes) easier for a reader to grasp.

In this lesson students will observe some objects that they see in the daytime sky and discuss reasonings to changes and movement of features in the day and night sky.

Students will observe, measure, sort, and examine (shapes and textures) of leaves individually, in groups, and in relationship to the entire plant.

Using paper, paper clips and tape, student teams design flying/falling devices to stay in the air as long as possible and land as close as possible to a given target. Student teams use the steps of the engineering design process to guide them through the initial conception, evaluation, testing and re-design stages. The activity culminates with a classroom competition and scoring to evaluate how each team's design performed.

In this lesson the students will create mixtures and note the physical properties of each of the ingredients within.

In this activity, students will create shadows and using this evidence they will write a scientific claim using evidence.

Students will determine a rule for classifying outdoor objects based on physical properties of matter.

Students will determine a rule for classifying outdoor objects based on physicalproperties of matter.

Students are introduced to the physical concept of the colors of rainbows as light energy in the form of waves with distinct wavelengths, but in a different manner than traditional kaleidoscopes. Looking at different quantum dot solutions, they make observations and measurements, and graph their data. They come to understand how nanoparticles interact with absorbing photons to produce colors. They learn the dependence of particle size and color wavelength and learn about real-world applications for using these colorful liquids.

In this hands-on activity rolling a ball down an incline and having it collide into a cup the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements and use equations that describe these energy of motion concepts to calculate unknown variables, and review the relationships between these concepts.

Students will make it a regular practice to record weather data using thermometers, wind vanes and rain gauges.

Building upon their understanding of forces and Newton's laws of motion, students learn about the force of friction, specifically with respect to cars. They explore the friction between tires and the road to learn how it affects the movement of cars while driving. In an associated literacy activity, students explore the theme of conflict in literature, and the difference between internal and external conflict, and various types of conflicts. Stories are used to discuss methods of managing and resolving conflict and interpersonal friction.

Students will use their knowledge of earth's natural resources to identify resources in the outdoor classroom and classify these resources as either renewable or non-renewable.

In this lesson, students learn about major landforms (e.g., mountains, rivers, plains, valleys, canyons and plateaus) and how they occur on the Earth's surface. They learn about the civil and geotechnical engineering applications of geology and landforms, including the design of transportation systems, mining, mapping and measuring natural hazards.

Students will explore the components of soil and make a model of sedimentary rock layers and fossil fuels.

Students will prepare the vegetable beds for planting exploring how simple and compound machines work.

Students research simple machines and other mechanisms as they learn about and make Rube Goldberg machines. Working in teams, students design and build their own Rube Goldberg devices with 10 separate steps, including at least six simple machines. In addition to the use of readily available classroom craft supplies, 3D printers may be used (if available) to design and print one or more device mechanisms. Students love this open-ended, team-building project with great potential for creativity and humor.
