Students match the forces with the pictures; calculate the resultant force; and state what the motion of the object will be (e.g. constant speed; accelerating;etc).

Guide to help students plan revision; includes forces and motion as well as materials such as Hooke's law and pendulums

A handout to introduce the different forces and the drawing of force diagrams. There are activities to develop literacy; learn what the difference forces and their effects are; draw force diagrams

Objective: Students will be able to differentiate between mass and weight. Students will be able to give examples of balanced and net forces. Keywords: Mass vs. Weight, Balanced Forces vs. Net Forces

Here is a fun resource based on the game Who Wants to Be a Millionaire? The presentation will test student knowledge of force and motion. The questions cover topics such as negative acceleration, positive acceleration, speed, velocity and the associated units of measurement.

Explore the forces at work in a tug of war or pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

The motion of an object can be described by its position, direction of motion, and speed. That motion can be measured and represented on a graph. * An object that is not being subjected to a force will continue to move at a constant speed and in a straight line. * If more than one force acts on an object along a straight line, then the forces will reinforce or cancel one another, depending on their direction and magnitude. Unbalanced forces will cause changes in the speed or direction of an object's motion. (NSES, 1996)

WHAT'S INSIDE: PHYSICAL SCIENCE

Central idea: Motion can be explained by three simply-stated laws known as Newton's laws of motion.

For the most part, in this section of Zona Land we will be discussing mechanical waves. Water waves and sound waves are examples of mechanical waves. Light waves are not considered mechanical waves. However, most of the mathematics and reasoning of mechanical waves applies to light waves.

Lesson Objective Journaling and narratives support student learning about magnets Length 7 min Questions to Consider How does journaling support independent student learning during the experiment? What is the role of storytelling in the learning experience? What do you think Mr. Rutherford means by "teach from the heart"?

Resources for elementary and middle school science educators

Lesson Objective Students explore electricity through the use of photovoltaic cells Length 5 min Questions to Consider Why is it important for students to identify the learning target at the beginning of the lesson? What strategies does Ms. Levine use to encourage student discussion? How does Ms. Levine extend the lesson so that students see a connection to their lives?
