Novel representations and diverse perspectives can reveal new insights into complex systems, and can support rich understandings of the world. In this activity, students will identify and analyze the choices artists and scientists make when creating representations of living or non-living natural objects. This process will help students recognize the potential and place for their own articulation of how the world works. After drawing from nature, students will reflect on the process of representing information, then compare their drawings with that of a 16th-century artist. Students will consider what is included and what is excluded, and hypothesize about larger contexts and systems.

This informational text explains the colorful phenomenon known as the northern lights (aurora borealis) and the southern lights (aurora australis). Students explore the cause of the aurora. The text is written at a grade four through five reading level. This is a PDF containing the informational text and a glossary.

This webpage from Exploratorium provides an activity that demonstrates the Bernoulli principle with readily available materials. In this activity a table tennis ball is levitated in a stream of air from a vacuum cleaner. The site provides an explanation of what happens, asks questions about the activity, and also describes applications to flight. This activity is part of Exploratorium's Science Snacks series.

Students explore static electricity by rubbing a simulated balloon on a sweater. As they view the charges in the sweater, balloon, and adjacent wall, they gain an understanding of charge transfer. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET). The simulations are animated, interactive, and game-like environments.

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change.

In this instructional video, the Hogle Zoo explains how to use the lesson plan "Beaver Puppet 2.2.2."

By participating in this activity, students will:
• understand the concept of structure and function and how it applies to a beaver's ability to create and live in a wetland habitat.
• make comparisons between their adaptations and the structure and function of a beaver's body for survival in its wetland habitat.

This powerpoint accompanies the lesson plan "A Night in the Life of a Beaver."

In this instructional video, the Hogle Zoo explains how to use the lesson plan "Beaver Tools of the Trade 2.2.2."

By participating in this activity, students will:
• understand the concept of structure and function and how it applies to a beaver's ability to create and live in a wetland habitat.
• make comparisons between unrelated objects through metaphorse to learn the structure and function of a beaver's body for survival in its wetland habitat.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale. This resource includes two activities that allow learners to experience the Bernoulli Principle, in which an object is suspended in air by blowing down on it. Use this activity to explain how atomizers work and why windows are sometimes sucked out of their frames as two trains rush past each other.

Explore the sounds of birds from all over North America in this interactive graphic.

Students will mix ingredients to create a chemical change and "Blobber" - a substance similar to silly putty.

When seen at night, the moon seems to shine brightly in the sky. What we actually see is the reflection of the sun's light on the moon. The moon gets its light from the sun, just like we do on Earth.

This brief article describes the historical methods of marking and measuring time. Among the instruments and methods discussed are sundials, water clocks, celestial motions, and mechanical clocks. Included are descriptions of the sources of inaccuracies of these methods. Links to related resources and a separate page of pedagogical notes are provided.
