An image of -- Western river birch, trunk -- is provided, drawn from the the collection of UTAH NATIVE PLANTS, contributed by the Red Butte Garden and Arboretum, University of Utah. The photographs show the changing appearance of various plants throughout the seasons. === Western river birch (Betula occidentalis) grows at 5,000- 9,000 feet and is usually found in riparian areas. ===

It’s 1770. You are Nat Wheeler, a 14-year-old apprentice in Boston. As tensions rise among Patriots, Loyalists, and others, can you decide where your loyalties lie? Play online or download the iPad app.

In this Cyberchase video segment, the CyberSquad finds the right combination switch, lever and button that will deactivate the force field protecting the stolen Black Crystal.

The is a google sites learning hub all about force and motion. There are different activities that cover what force is, pushing and pulling, and simple machines. There is also a fun activity to learn about some famous scientist (some of whom contributed to the knowledge we have of force). Activities included use google earth, google forms, google slides, and other google tools. 

The law of universal gravitation states that all objects in the universe are attracted by the force of gravity. The law of universal gravitation is responsible for the moon remaining in orbit around Earth.

This car would weigh less on the moon than it does on Earth because the force of gravity on the moon is less than the force of gravity on Earth. However, its mass is the same.

Anticline folds are created by arching rock layers. Syncline folds are downward folds of rock layers.

Faulting is the process by which rock layers break when placed under stress.

A normal fault is formed when the forces of stress cause the hanging wall to move downward relative to the foot wall.

The process of compression can cause the hanging wall to move up in relation to the foot wall, forming a reverse fault.

Rock compression is the process of rocks in the crust being squeezed, which often makes rocks denser and may push rocks higher or lower.

Rock shearing is the process by which rocks in the crust are twisted or torn apart.

A thrust fault is formed when the hanging wall moves up and over the foot wall. Thrust faults are common in mountain ranges where intense folding is found.

The goal of this lesson is to assist students to relate the forces acting upon particular objects and the “unseen” resolution of those forces. The video begins with a story line involving Adam, who helps his father in the garden by disposing of a garbage bag of leaves—the very act that involves resolution of forces. This lesson includes embedded video clips, animations, diagrams and inquiry-based experiments where students are required to work collaboratively and answer thought-provoking questions. The experiments will involve the study of the resolution of forces on objects placed on varying planes or on platforms of different angles, using materials that are easily found. Finally, students are required to discuss and apply what they have learned to determine whether it is easier to push or to pull a luggage bag with wheels. The lesson will take about 50 minutes to complete.
