Part A Choose a tool or a device you can investigate. It must not have any source of power other than the person using it. It must use one or more of the six simple machines. Explain how the tool or device is used. What work does a person do while using it? What kind of motion do we see when it’s used?

Part B
Which simple machines are used in the tool or device?

Part C
What materials are used to make the tool or device? Why did the designers pick those materials?

Part D
Question
Draw the tool or device, and label where the input force is exerted and where the output force is exerted.

Part E
Mechanical advantage is the ratio of output force to input force. Does the tool or device have a mechanical advantage that is greater than 1, equal to 1, or less than 1? Do some research on the Internet or at a library if you aren’t sure.

Part F
Suggest one or more improvements that designers could make to the tool or device.

Which of the following are not typically included in the periodic table? a. atomic mass b. element symbol c. isotopes d. number of electrons

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
