A collection of resources on how humans use machines and tools to meet their needs. Covers simple and complex machines, subsystems that transfer forces, mechanical advantage, speed ratio, the effect of friction, efficiency, the science...

Students reflect on their experiences making silly putty (the previous hands-on activity in the unit), especially why changing the borax concentration alters the mechanical properties of silly putty and how this pertains to tissue...

Prosthetic limbs and artificial joints can help people with disease or injury lead a normal life. Sports medicine or physical therapy is also an area that relates to this experiment. Either way, this project serves as a good match if any...

The human eye is an amazing mechanism, able to detect anywhere from a few photons to a few quadrillion, or switch focus from the screen in front of you to the distant horizon in a third of a second. How did these complex structures...

This site details how simple machines create a mechanical advantage for humans. Levers, theoretical mechanical advantage, actual mechanical advantage, and pulley systems are discussed.

Students will apply the concept of levers to the human body and build all three classes of levers within a musculoskeletal context. They will be shown how the musculoskeletal system is a system of levers and one example of each type of...

The National Humanities Center presents collections of primary resources compatible with the Common Core State Standards - historical documents, literary texts, and works of art - thematically organized with notes and discussion...

Have fun learning about the human body's respiratory system while playing games in Professair's Mad Lab! These interactive games have colorful graphics and are broken into three grade groupings: grades one to three, four to six, and...

This teacher's resource page accompanies the student website ?Inside the Human Body: The Respiratory System? for grades seven through twelve from the Canadian Lung Association. This site walks teachers through the features of the student...

This website challenges students to make a ball and socket joint that mimics the movement of a human hip or shoulder. Using only a tennis ball, rubber bands, cardboard, and tape, students will construct this mechanical device. The site...

This teacher's resource page accompanies the student website "Inside the Human Body: The Respiratory System" for grades four through six from the Canadian Lung Association. This site walks teachers through the features of the student...

As an epidemiologist on the U.S. Panel for Climate Change, students are tasked with analyzing the latest data on climate-impacted human health conditions. A solid understanding of the mechanisms underlying the connections will allow for...

Definition of a Motorcycle Mechanic is provided, including the description of duties, working conditions, skills, interests, values that are helpful, educational requirements, opportunities for employment and advancement. Some statistic...

Print this resource off as a worksheet or use it as a teaching tool. The site provides viewers with the ins and outs of the human respiratory system. Label diagrams, list the order of the route of air, note the mechanism of breathing,...

Discusses the methods the human body uses to regulate body temperature. Includes links to the four external heat transfer mechanisms (radiation, conduction, convection, and evaporation of perspiration).

In this investigation, students will study joints by comparing mechanical devices to living joint movement to understand how different kinds of joints work. Students will also determine where these joints are located in the body....

In small groups, students will experiment and observe the similarities and differences between human-made objects and nature. The students will compare the function and structure of hollow bones with drinking straws, bird beaks, tool...

This is a very detailed site on breathing/respiration. It covers system organization, mechanics, exchange of gases, and oxygen transport. A very thorough site.

This activity helps students understand how a LEGO MINDSTORMS NXT robot moves using motors and wheels. Then students relate the concepts of decision-making actuation and motion in humans to their parallels in mechanized robots, and...

Students learn about rotary encoders and discover how they operate through hands-on experimentation. Rotary encoders are applied in tools to determine angle measurements and for translations of angular motion. One common rotary encoder...

Learn about levers and make the connection between these simple machines and the human body.

Two statements issued by workers' groups advocating greater equality for all who labor.

A video [4:48] overview of responsibilities of Aircraft Maintenance Engineer including: duties, working conditions, personal characteristics, education, and salary.

Study the process of by which humans respond to their environment to reach equilibrium in this tutorial. Learn that feedback mechanisms trigger living things to respond to their environment.
