Explore the physics and material science of making stone tools. Educator Nate Salzman walks us through the surprisingly complex science of flintknapping, or the process of turning stone into blades, arrowheads, spear points, axes, jewelry and more. Making tools from stone may be thousands of years old, but required people to think about the properties of the material they were using and the physics of striking the stone to shape it just right.NOTE: These are animations derived from the video "The Science of Knapping" which is linked here and published under its own listing on OER Commons.This resource is part of Jefferson Patterson Park and Museum’s open educational resources project to provide history, ecology, archaeology, and conservation resources related to our 560 acre public park.

This Anne Frank unit is designed with several lessons of various lengths. These lessons are usable in many different disciplines. Using one, several, or all of the lessons will address the unit's objectives to some degree. Students will accomplish some or all of the objectives depending on the number and nature of the lessons in which they participate.

This series of lessons provides an overview of what is a postage stamp and its history within Canada. Students then learn about the life and art of the Alberta artist Annora Brown. Nearly 200 of her wildflower paintings are held by the Glenbow Museum in Calgary.Once students know more about stamps and the art of Annora Brown, they may create their own postage stamps. Secondly, they learn about writing persuasive letters and are asked to write to the Canada Post Office requesting a series of stamps based on the wildflower paintings of Annora Brown.

This informational text explains that while both the Arctic and Antarctica are cold, Antarctica is much colder and drier - a polar desert. The text is written at a grade four through grade five reading level. This is a PDF containing the informational text and a glossary.

Students will be given the opportunity to explore the different types of questions.

Farming ants might sound like a crazy thing to do unless you might like to eat chocolate covered ants. It turns out we can learn a lot from ants and the best way is to build your own ant farm.

The Polar Rock Repository at the Byrd Polar and Climate Research Center offers no-cost Rock Boxes for use by educators in both schools and informal learning environments, such as libraries, scout groups, and Science Olympiad teams. Each box may be borrowed for one month and contains more than 30 representative samples (rocks, minerals, fossils), printed materials for student use (books, descriptions, etc), teacher materials (also available online), and tools to examine the samples. With few exceptions, all of the samples in the boxes were brought back from Antarctica over the past century by U.S. expeditions!
A virtual version of the Rock Box may be viewed here. In addition to 3D models of rock samples, high resolution photographs and descriptions are linked.

What happens when the ground under your feet is ice and it's moving? This video segment adapted from NOVA features some of the dangers faced by scientists conducting research in Antarctica.

This article describes a discovery of moss and ostracod fossils that led to a better understanding of Antarctica's climate history.

This article includes links to expository text for students in grades K-1, 2-3, and 4-5 about the climate differences between the Arctic and Antarctica.

This informational text explains that while both the Arctic and Antarctica are cold, Antarctica is much colder and drier - a polar desert. The text is written at a grade two through grade three reading level. This version is a full-color PDF that can be printed, cut and folded to form a book. Each book contains color photographs and illustrations.

This video segment adapted from NOVA uses microwave images to reveal how sea ice doubles the size of Antarctica each winter. Rare footage shows how sea ice crushed the famous ship Endurance in 1914.

Nine-year old Anthony is proud of his history, culture, and family tradition of Mexican rodeo-style roping and riding. He also enjoys various aspects of his modern life such as school, basketball, friendships, swimming, and exploring.

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side. To make the effect more dramatic, cover the mirror with a cloth, climb onto the table, straddle the mirror, and then drop the cloth as you appear to "take off." This resource contains information about how this trick was applied during the making of the movie "Star Wars."

Before conducting this activity, educators may want to discuss historical information about racism and diversity issues. In the story The Sneetches, written by Dr. Seuss, yellow bird-like creatures take students on an adventure where green stars become the symbol of discrimination and privilege. After reading the story aloud, let students participate in the following activities that can be adapted with or without the story.

In this simple exploration, a coiled phone cord slows the motion of a wave so you can see how a single pulse travels and what happens when two traveling wave pulses meet in the middle.

In the explorable explanation players can learn how antibiotic resistance happens. They can interact with bacteria in this simulation to learn how when living things reproduce, there is a small amount of variance in their offspring. This allows organisms to respond to changes in their environment over several generations. Applied to bacteria, when they treated with antibiotics, only the strongest survive and multiply, creating an increasing resilient population.

ACTIVITY OBJECTIVE: A great decision-making activity for kids that will also build their thinking and reasoning skills.
