• Identifying forces that change an object’s position or motion

• Examples:   lifting, pushing, pulling

• Identifying sources of friction

• Examples:   rubbing hands together, applying sandpaper to wood

• Describing the force of gravity

Falling
Student will explore the role of gravity in falling.

Magnets
Students will perform a variety of experiments with magnets and record findings on an activity sheet.

How Strong is Your Magnet? 
Student will experimentally measure the strength of a magnet and graph how the strength changes as the distance from the magnet increases.

Do I Push or Do I Pull?
Students work individually to experience and classify pull forces and push forces. They will draw examples to display on a bulletin board.

Mickey’s Magnets
In this lesson, students will study magnetism and its properties, including forces.

Amazing Magnets
This eleven lesson unit shows you how to engage students in experiments which explore magnet force and compass use. Using constructive techniques, this course of study focuses on asking thoughtful, open-ended questions which, in turn, encourage students to ask questions of each other.

Weightlessness and Gravity
Students will learn about the effects of weightlessness on humans and objects in space. Students will experiment to discover the benefits of gravity.

May the Force Be With You
This hands-on activity will help students understand the greater mass of an object, the greater the force needed to change its motion.

Friction in Our Lives
With this experiment, students will explore friction and discuss examples of friction in everyday life.

Friction
Students will make predictions and record results for a friction activity. Students will also gain an understanding of how surface material affects movement.

Buoyancy
Students will experiment with clay and water to explore buoyancy.

Will It Float or Sink?
Students will determine whether certain objects will float or sink and design a boat that will float and hold weight.

A Magnet Experiment This counting and magnetism experiment explore magnet strength.

BrainPop: Buoyancy This website has a science video clip about buoyancy.

Nova: Buoyancy Brainteasers: This site has good teacher information about buoyancy. There is a link to Buoyancy Basics that has some good graphics.

Why Do Astronauts Float Inside the Space Shuttle? This video clip relates floating in the shuttle to riding in an elevator.

Suggestions for English Language Learners (ELLs): (E/B=Entering/Beginning, D=Developing, E=Expanding)  (E/B, D, E): Experiment with a magnet and group small objects into two groups (sticks to magnet/doesn't stick to magnet). Using a T-Chart with these headings, have the students tape the items to each list (E): and add labels. (E/B): Students will use magnets to push toy cars across their desks. They will then draw a picture to show what they have observed; (D): ...and will be given magnets of various strengths to push cars across the table, then chart which magnets exerted more force; (E): ...and will use the charted information to teach other students how magnetic force can be used to move objects. (E/B): Students will mix iron filings with salt and sand and use a magnet to separate substances. Students will show the steps used in the experiment through labeled pictures; (D, E) ...and will write several sentences about procedure and information observed in each step. (E/B) Students attach two balloons to string and suspend them upside down. They will then choose several materials (wool, fur, hair, etc.) to rub against each balloon and record through pictures what happens; (D): ...and will chart which materials attract and repel; (E): ...and will infer why certain materials cause a specific reaction. (E/B): Students will graph and label the results of dropping different objects from a variety of heights; (D): ...and will make oral and written generalizations about falling objects; (E): ...and will do the same using more complex language. (E/B): Students will drop a superball from heights of one foot, five feet and ten feet. Students will chart the ball's height after each drop; (D): Students will drop different sized balls, then chart, describe and make generalizations about the results; (E): ...and will list all variables which affect how high the balls bounce.
