A simple machine is a device used to assist people in getting work done faster and easier. Scientifically, work is known as using force upon an object in order to transport it to a new location. Pushing, pulling, and lifting are all common forms of work. Simple machines can used to simplify these actions, making it easier for the laborer to complete the task.
Pulleys, levers, wedges, screws, wheels and axles, and inclined planes are all examples of simple machines. They can all help people do work in some form. For example, a gardener must remove the weeds from his garden on a regular basis. He could use his bare hands, but using a shovel, a lever tool, will allow the job to be done with less effort.
In another example, inclined planes are useful in helping movers load furniture into trucks. By using a ramp, they are able to roll the large items into the truck on wheels rather than lift them.

Used for splitting, tightening, securing or levering. It is thick at one end and tapered to a thin edge at the other. Wheel and axle: A simple machine that reduces the friction of moving by rolling. A wheel is a disk designed to turn around an axle passed through the center of the wheel.
A Day in the Life with Common Simple Machines
An axle is a supporting cylinder on which a wheel or a set of wheels revolves. Work: Force on an object multiplied by the distance it moves.
On a large sheet of paper or on the classroom board, draw a chart with the title "Building with Simple Machines. Fill out the K and W sections during the lesson introduction as facts and questions emerge. Fill out the L section at the end of the lesson. Review the information and answer any questions. Suggest the students keep the sheet handy in their desks, folders or journals. Closing Discussion: Conduct an informal class discussion, asking the students what they learned from the activities. Ask the students:. Remind students that engineers consider many factors when they plan, design and create something.
List all of the things they learned about simple machines. Were all of the W questions answered? What new things did they learn? Take-Home Quiz: Gauge students' understanding of the lesson by assigning the Simple Machines Worksheet as a take-home quiz. Use the attached Simple Machines Scavenger Hunt! Worksheet to conduct a fun scavenger hunt. Have the students find examples of all the simple machines used in the classroom and their homes. Illustrate the power of simple machines by asking students to do a task without using a simple machine, and then with one.
For example, create a lever demonstration by hammering a nail into a piece of wood. Have students try to pull the nail out, first using only their hands. Bring in a variety of everyday examples of simple machines. Hand out one out to each student and have them think about what type of simple machine it is. Next, have students place the items into categories by simple machines and explain why they chose to place their item there. Ask students what life would be like without this item.
Emphasize that simple machines make our life easier. Engineering Design Fun with Levers: Give each pair of students a paint stirrer, 3 small plastic cups, a piece of duct tape and a wooden block or spool or anything similar. Challenge the students to design a simple machine lever that will throw a ping pong ball or any other type of small ball as high as possible. In the re-design phase, allow the students to request materials to add on to their design.
Have a small competition to see which group was able to send the ping pong ball flying high.

Subscribe to our newsletter. Educators Share Experiences. Summary Simple machines are devices with few or no moving parts that make work easier. Students are introduced to the six types of simple machines — the wedge, wheel and axle, lever, inclined plane, screw, and pulley — in the context of the construction of a pyramid, gaining high-level insights into tools that have been used since ancient times and are still in use today.
In two hands-on activities, students begin their own pyramid design by performing materials calculations, and evaluating and selecting a construction site. The six simple machines are examined in more depth in subsequent lessons in this unit. Engineering Connection Why do engineers care about simple machines? Grade 3 Do you agree with this alignment? Science investigations use a variety of methods, tools, and techniques.chatsingkrontaqi.tk

Each force acts on one particular object and has both strength and a direction. An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object. Forces that do not sum to zero can cause changes in the object's speed or direction of motion. Boundary: Qualitative and conceptual, but not quantitative addition of forces are used at this level. Objects in contact exert forces on each other. Cause and effect relationships are routinely identified. View other curriculum aligned to this performance expectation.
Science findings are based on recognizing patterns. The patterns of an object's motion in various situations can be observed and measured; when that past motion exhibits a regular pattern, future motion can be predicted from it. Boundary: Technical terms, such as magnitude, velocity, momentum, and vector quantity, are not introduced at this level, but the concept that some quantities need both size and direction to be described is developed. Patterns of change can be used to make predictions.

Sometimes it is hard to understand how forces help you. Scissors can also be used to cut hair work easier. There are 3 types of simple machines: 1. Skateboard introduce was the Lever which is found readily on a skateboard - What are the simple machines that were illustrated and demonstrated by Dr. Skateboard in the video clip? It has an upturn area in front and as well at the back of the board. The upturn area access the lever for the rider and helps lessen the force excreted for the rider while jumping on an obstacles like rocks on the streets.
Skateboard introduce was Wheel and Axle. It provides transportation and lifting power. And the 3rd type of simple machine that Dr.
