What would be the MASS of a 25 cm3 piece of iron?  1.  The density for iron is 7 g/cm3.        What would be the MASS of a 25 cm3 piece of iron?       HINT: MVD (mass = volume x density)  175g/cm3 393g 175g 3.18g

The density for aluminum is 2.7g/cm3.        What would the VOLUME be for a piece of aluminum that has a mass of 13g?       HINT: VDM volume = density divides the mass (mass divided by density).      4.81cm3 0.207cm3 4.81g/cm3 35.1cm3

3. A substance has particles that are close together with no regular arrangement. The particles vibrate and slide past each other. The substance is difficult to compress and flows easily. This substance is most likely a...? gas liquid solid plasma

4. The bar graph below contrasts phases of matter. Notice that the label for this bar graph’s vertical axis is missing.  Which of the following choices would be the best label for the vertical axis in this graph? a. flavor b. color c. electrical charge d. temperature

How can the student best test the strength of the generator? 5. A student built an electric generator prototype. The generator was designed to give power to electrical devices. How can the student best test the strength of the generator? a. place a magnet on a spring scale and record the force of the magnetic field b. place the generator on an electronic balance, and record its mass in kilograms c. connect the generator to a circuit that contains appliances and then observe if the appliances work.

6. Technicians plan to develop a new type of keyboard that will have alphabet letters in different positions from a standard keyboard. Which will best help the technicians decide if the new keyboard is an improvement over the standard one? a. analyzing the problems that people have using standard keyboards b. asking people their opinions of how they like standard keyboards c. comparing the speeds at which people type on each style of keyboard

7. All too often, modern technology items end up being thrown away once newer and faster models are available. Which example of modern technology shown below can harm the environment? a. Disposing of old computers in landfills where toxic chemicals may leak into the soil b. Designing more efficient car engines that burn less gasoline per mile c. Using cloth bags at grocery stores instead of using throw-away plastic bags

1st Verse: They’re tiny and they’re teeny, Much smaller than a beany, They never can be seeny, The Atoms Family. Chorus 2nd Verse: Together they make gases, And liquids like molasses, And all the solid masses, The Atoms Family 3rd Verse: Neutrons can be found, Where protons hang around; Electrons they surround Chorus: They are so small. (Snap, snap) They’re round like a ball. They make up the air. They’re everywhere. Can’t see them at all. #18.Atom’s Family Success Criteria: I can recognize that all matter consists of atoms.
