Explanations
1. In order to measure the volume of an irregularly shaped object, it is necessary to use the water
displacement method. In this method, you must...





fill a graduated cylinder halfway full with water,
measure the initial volume of water by looking at the bottom of the meniscus,
drop the object into the water,
measure the final volume of water by looking at the bottom of the meniscus,
subtract the initial volume of water from the final volume of water to determine the
volume of the object.
2. When heating chemicals in a test tube, it is most appropriate to point the opening of the test
tube away from oneself and others.
Holding the test tube straight up and down would actually increase the chance of the contents
bubbling over. Never heat a container that has a tight cap. The container could explode.
3. In order to use the balance, an object is placed on the platform. Then, the sliders on the beams
are moved to indicate the mass in hundreds, tens, and ones (and tenths) until the pointer lines
up with the zero mark. Finally, the mass is read from the beams.
4. Devices like the one pictured are called anemometers, and they are used to record wind
speeds. Regularly monitoring wind speeds helps scientists to forecast changes in weather.
5. When using a barometer to measure a change in air pressure, the set pointer is placed on top
of the reading pointer. Then, if the reading pointer changes position, the change in pressure can
be determined.
6. Different adaptive technologies are suited for different disabilities. Somebody who has lost a
limb would benefit from a prosthetic device (artificial arm or leg) or wheelchair. Somebody who
has trouble walking would benefit from a walker, wheelchair, or leg braces. Somebody who
can’t see well can use glasses or contacts. Somebody who can’t hear well can often benefit from
a hearing aid.
7. A telescope makes objects that are very far away appear larger. This makes them easier to
observe. Objects like stars and planets are often observed through telescopes.
8. A graduated cylinder is used to measure the volume of a liquid. This would be the best tool
to measure the volume of water he has in the glass.
9. To test the effects of air temperature on the rate of evaporation of water, Nancy could design
an experiment in which she pours a certain amount of water into graduated cylinders, places the
cylinders in rooms of different temperatures, and returns after a certain amount of time to
measure how much liquid water is left in the cylinders. In order to do this she would need a
thermometer and a graduated cylinder.
10. A metric ruler is used to measure the length of an object. This would be the best tool to
measure the length of the apple from top to bottom.
11. Rubber gloves allow scientists to handle many objects that are too dangerous to be handled
by bare hands. However, there are still many objects that should not be handled, even with
rubber gloves. Also, some people are allergic to rubber and must use other kinds of gloves.
12. A pH probe connects to a computer to display and record the numerical value for the pH of a
solution. Indicator solutions, red cabbage juice, and pH paper can only give an approximate pH
value.
A pH meter can also give the numerical value of a solution's pH, but it does not need to be
connected to a computer.
13. After Sachiko places the room-temperature thermometer in the beaker of ice water, the
mercury level will immediately begin to drop. It will take several seconds for the thermometer to
adjust to the new temperature. To obtain the most accurate reading, she should watch the
mercury level closely and take the reading immediately after the mercury level has become
stable.
14. A spectroscope is a tool that divides light into the different colors that make it up. Most light
sources—including light bulbs, flashlights, and the Sun—emit many different colors, but not all
colors. A spectroscope can help an observer determine which colors are released by the light
source and which colors are not.
15. The relative humidity an important factor used to predict the weather. The combination of
humidity, the air temperature, and the barometric pressure help predict whether precipitiaton will
fall.
Meteorologists measure the realtive humidity using a hygrometer.
16. Optical telescopes have been used by astronomers for hundreds of years. Galileo first used an
optical telescope to observe Jupiter and the Moon in the early 1600s. But images created by landbased optical telescopes have always been blurred by the Earth's atmosphere.
The air surrounding the Earth bends and scatters light coming from stars, making the stars appear
to "twinkle." Space telescopes, such as NASA's Hubble Space telescope, are above Earth's
atmosphere. This vastly increases their ability to see great distances with incredible detail.
17. Betty could us a hand lens to examine the leaves' veins in greater detail. Hand lenses make
objects close behind them appear larger. If Betty uses a hand lens, it will be easier for her to
observe the patterns she is studying.
18. If the flame of a bunsen burner goes out for any reason, the gas should immediately be turned
off. If this procedure is not followed, gas could build up in the classroom and cause a fire or
explosion. Students may also become ill from inhaling the gas.
19. The invention of the microscope and its use in studying cells show that technology can
contribute to and increase scientific knowledge.
When new technologies are invented, they often aid scientists in discovering new information or
altering a present view of a scientific topic.
20. The sequence of steps for lighting a Bunsen burner is as follows:
1. Connect the burner hose to the gas outlet.
2. Open the gas valve on the gas outlet.
3. Open the gas adjustment at the base of the Bunsen
burner.
4. Apply the spark above the barrel of the
Bunsen burner.
