General Lesson Information
 Lesson Plan ID: 23807 Title: Investigating Friction Overview/Annotation: Students will experience friction in action. Students will work actively in small groups to promote socialization and teamwork. Students will experience different types of matter and materials to explore the impact of friction.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Associated Standards and Objectives
Content Standard(s):
 Mathematics MA2015 (2016) Grade: 4 22 ) Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Solve problems involving addition and subtraction of fractions by using information presented in line plots. [4-MD4] Example: From a line plot find and interpret the difference in length between the longest and shortest specimens in an insect collection. Alabama Alternate Achievement Standards AAS Standard: M.AAS.4.22- Interpret data on a pictograph or bar graph to solve a problem.

Local/National Standards:

National Standards were found at Education World
•Unifying Concepts and Processes: change, constancy, and measurement
•Science as Inquiry: abilities necessary to do scientific inquiry; understanding about scientific inquiry
•Science: Physical Science — understands forces and motion
•Science: Nature of Science — understands the nature of scientific knowledge; understands the nature of scientific inquiry
•Mathematics — understands and applies basic and advanced properties of the concepts of measurement
•Physical Science: motions and forces; position and motion of objects

Primary Learning Objective(s):

The students will: •demonstrate an understanding of the terms: force, gravity, friction, and speed. •experiment with the effects of friction on speed and motion. •understand that friction and other forces have an effect on speed and motion.

The students will use appropriate language to express their thoughts and ideas. The students will also work cooperatively in small groups.

Preparation Information
 Total Duration: 31 to 60 Minutes Materials and Resources: •Books, blocks, or other stacking materials •36" x 12" (1 m x 30.5 cm) pieces of smooth plywood or other sturdy, flat material, 1 per group •Small toy cars with moving wheels, one per student group •Pennies, washers, or other small uniform objects with weight, 6 per student group •Tape •1-foot (30.5 cm) sheets of heavy duty sand paper, 3 per student group •3-foot (1 m) sheets of wax paper, 1 per student group •3-foot (1 m) sheets of bubble wrap, 1 per student group•Pencils and erasers •Science journals or writing paper •Stop watch (or watch with second hand), 1 per student group •Meter stick, 1 per student group Technology Resources Needed: Forces and Motion with Sasha and Zoe video from YouTube(see attached) You could also order Discovery Education's DVD Forces and Motion. The DVD can be ordered from the Discovery Education website You will also need a VCR, or DVD player, as well as a computer with Internet access. Also, the following is an optional resource you may wish to use: Virtual Laboratory: Kinetic Energy Background/Preparation: The teacher will be familiar with force, motion, gravity, and speed. The teacher will posses basic knowledge of the above terminology. The students will have a basic understanding that objects have the ability to move independently or be placed in motion by some other object or force. The students will have the basic understanding that objects move on different surfaces.Students should be familiar with the following vocabulary: acceleration: The rate of which an object changes its velocity. Context: Acceleration can be positive or negative depending on whether the object is speeding up or slowing down.force: A push or a pull exerted on an object. Context: The ball was hit with enough force to send it into the bleachers. friction: A force that resists motion between two bodies in contact Context: Rougher surfaces create more friction than smooth ones when an object comes in contact with them. gravity: The natural force that attracts any two objects with mass toward each other. Context: Earth's gravity pulls on anything that is not held up by some other force. speed: The rate of motion. Context: The speed of the ball is determined by measuring how far it travels in a certain amount of time. velocity: The speed of an object moving in a specific direction. Context: The car's velocity was 55 miles per hour, eastbound.
