Planning a unit on simple machines? Save some time and energy with this collection of lessons and activities that explores how these devices are used in the real world to make life a little easier. 

Find a way to work with rates. The 23rd part in a 29-part series presents work problems for the class to solve given work rates. Pupils compare rates to determine which is faster. Some problems require learners to convert the rates to...

Teach young engineers that all machines, no matter how complicated or complex, are made up of just six simple devices with this hands-on physical science lesson. Using the included templates, students first create paper models of...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

How much work is done when a force moves a block? How far will power lift a block? And how much work can be done by a motor? These are the kinds of questions you will find on this physics problem solving sheet. With 19 problems to solve,...

A total of 29 word problems furnish practice in solving for work, energy, and force. A few of the questions display diagrams to help learners visualize the systems, and all of them list five choices from which they select the correct...

Written out on this page are 22 problems for physics aces to solve. There isn't enough room for them to solve on the same page, so they will need to be set up and computed on a separate sheet of paper. Pupils answer questions such as,...

Students discuss that the conservatin of energy states that the energy imput must equal the energy output. They then figure out how can a machine help you to perform task otherwise considered impossible? Students discuss the six simple...

All work and no play make Jack a dull boy, while all text and no graphics make Energy a dull presentation. It is informative, teaching viewers about work, conservation of energy, and sources that can be used to generate electricity. It...

Microsoft's Flight simulator is the focal point of this instructional activity. By participating in this activity, teenagers role-play what is necessary for piloting an airplane. They explore the concepts of flight. You will need to...

In this kinetic energy worksheet, students solve six problems including finding work, determining kinetic energy, finding the coefficient of kinetic friction and finding work done on objects by air resistance and friction.

Students are introduced to the concept of thermodynamics. In groups, they participate in experiments in which they discover how potential energy converts into kinetic energy. They use the internet to research the components of a...

Students study concepts of energy and energy transfer. They look at how these concepts apply to musical instruments. They study the law of conservation of energy. They use the concepts studied in the lesson to design a musical instrument.

Students distinguish between kinetic and potential energy. They recognize that energy can change from one form to other forms. They identify and describe several forms of energy.

Students explore the importance of classroom jobs. They observe a puppet who is irresponsible and never gets her work completed and then discuss whether or not this puppet should be given a classroom job. As a class, they examine the...

Third graders examine simple machines. In this simple machines lesson, 3rd graders observe simple machines at work in a video, then experiment with creating their own simple machines to move objects.  

In this work instructional activity, students are given a picture of people in a Victorian street doing all different types of work. Students fill in bubbles with what each person may be thinking.

In this power worksheet, 12th graders solve four problems including calculating work done by friction, determining work done by gravity and the calculating the minimum horsepower needed to save a ship that is sinking.

In this machines instructional activity, students review different types of simple machines including pulleys, wedges, levers, and inclined planes. This instructional activity has 10 matching, 4 multiple choice, and 8 short answer...

In this math worksheet, students apply the following: In physics, the equation W=Fd gives the amount W of energy expended in moving a distance d by applying a constant force F.

Pupils listen to a lecture by the teacher about farm work and ways to use physics to make farm work easier. The machines that are highlighted include pulleys, ramps, lever, and gears. Each machine is explained in context of its use in...

Learners explore numerous types of careers. As a class, they list people they know and the types of jobs and services that are provided. Students discuss the responsibilities of having a job. Volunteer learners explain what they wish...

First graders discuss work, force, and energy. They study how work is done. Students discuss various types of work that are done. They act out how work is done. Student draw pictures of types of work they have done.

First graders study and describe simple machines such as the hammer, screwdriver, nutcracker, bottle opener and scissors and select the appropriate tool for a particular type of work.
