1. Topic-
Force and Motion
 
2. Content-
Learning the difference between force and motion. Learning how gravity and friction effect motion
 
3. Goals: Aims/Outcomes-
1.Understand the difference between force,gravity and friction
2.Participate in scientific inquiry
3.Demonstrate ability to form a hypothesis and test it
 
4. Objectives-
1 Demonstrate an understanding of the terms force, gravity, friction and speed
2.Experiment with the effects of mass and friction on speed and motion
3.Understand that friction and other forces have an effect on speed and motion
 
5. Materials and Aids-
-Forces and Motion DVD
-books, blocks or stacking material
-plywood or other sturdy surface
-small toy cars with moving wheels, one per group
-pennies, washers, or other uniform object with weight, 6 per group
-tape
-1 ft sheets heavy duty sand paper, 3 per student
-3ft sheets of wax paper, 1 per group
-3ft sheets of bubble wrap
-pencils and erasers
-science journals
-stop watch
-meter stick
-computer (optional)
 
6. Procedures/Methods-

A. Introduction-

1.How do objects move? Watch DVD
2.What can stop that movement?
 

B. Development-

1.Make a ramp by placing one or more books under one end of plywood.
2.Gently push toy car down the ramp and measure speed and distance
3.How can we make it go faster or further?
 

C. Practice-

1.Divide class into groups.Supply each group with stacking materials, plywood and a toy car
2.Allow the groups a few minutes to experiment with the ramps.
3.Ask the groups to stick with angle that worked best.
4.have children gently push car down ramp three times and record distance and speed. Then find the average.
5.Give them pennies, washers or other objects to tape to top of car. Hypothesize how this will effect the speed and distance
6.Place the wax paper on the ramp and test the speed and distance. Continue to test with sand paper and bubble wrap. Record results.
 

D. Independent Practice-

Children discuss what they have seen and record it in their journals.
 

E. Accommodations (Differentiated Instruction)-

1.Larger materials and cars can be provided
2.One on one assistance will be available
3.Interpretations can be made in other languages.
 

F. Checking for understanding-

1.Students were able to explain why there were differences in the speed and distance.
2.Children were able to identify which materials would impact the motion of the car.
3.Children could describe the difference between force and friction
 

G. Closure-

1.What other things could affect the motion of an object?
2.Conclude during which phase the car moved faster and further.
 
7. Evaluation-
1.Children define the meaning of the words force, friction, and motion
2.Children apply what they learned to other objects.
