are there so many different kinds of insects in the world?Slide5

Question 4

When

performing scientific investigations, scientists often use different approaches. For example, one scientist might add an extra step to his or her investigation that another scientist's investigation does not need. In other cases, certain steps might be repeated or arranged in a different order.

Even with all the different ways scientists can approach a problem, there are some basic steps that usually occur in the same order. For a single scientific investigation, which of the following shows steps in the most appropriate order?

A

.

experimental data draw conclusions question hypothesis

B

Question 5

Peter

wants to figure out which insects have 4 legs, 6 legs, and 8 legs. He decides to do this by

A

.

collecting

B

.

trying

to remember how many legs each type of insect has.

C

.

performing

experiments on several types of insect legs.

D

.

making

a model of an insect and counting the number of legs.Slide7

Question 6

For

the past four years, Mr. Thompson has kept a pet boa constrictor in his science classroom. At the beginning of each year, his students measure the length of the snake and record the result.

The table below shows the measurements for all four years.

Year

B

.

The

amount it grows changes every year.

C

.

Yasmeen

dispose of by pouring into the sink?

Question 8

In

Randy's science class, each lab group must identify an unknown compound in a test tube. One of the characteristics that the students will observe to help identify the compound is odor. Which of the following describes the appropriate way to detect the odor of the substance in the test tube?

A

.

Inhale

directly above the opening of the test tube.

B

.

Pour

some of the unknown on a paper towel and sniff the paper towel.

C

.

Wave

your hands over the test tube to direct some of the odor toward your nose.

D

.

Pour

some of the unknown into a dish and inhale directly from the dish. Slide10

A

.

Nothing

, let the blood coagulate and stop itself.

B

.

Press

a clean towel or cloth firmly against the cut.

C

.

Lie

down and raise her arm straight up.

D

.

Wash

the cut with any liquid that is nearby. Slide11

Question 10

Barbara

completed an assignment for extra credit in science class. She used a pH meter to find the pH of different substances.

After she finished measuring the

pHs

, she created a diagram that showed the substances arranged in order from the most acidic to the most basic.

If Barbara added stomach acid—pH 1.3—to her investigation, where should it appear in her diagram?

A

.

between

milk and water

B

.

to

the left of cola

C

.

between water and blood D. between soap and bleachSlide12

Question 11

A group of scientists suspects that a certain well-accepted theory is not accurate. They decide to perform several experiments to test the theory with new research techniques. The experiments support the scientists' idea that the theory is incorrect.

After sharing these results with the scientific community, other scientists perform experiments to test the established theory. All of the new data are combined, and it is determined that the theory is most likely incorrect.

By questioning the accuracy of the established theory, the work of the original group of scientists

A. was automatically accepted by the public.

B. broke a fundamental rule of experimental procedures.

C. led the scientific community to new understanding.

D. was found to be unimportant by other scientists. Slide13

Question 12

A scientist is skeptical of a widely accepted theory. He decides to perform an experiment to test the theory. The experiment's results support the current theory.

Was the scientist's experiment useful?

A. No. It had no effect on the scientific theory.

B. Yes. It disproved the current theory.

C. Yes. It provided more support for the theory.

D. No. It provided no new information. Slide14

Question 13

Before Daniel performed his experiment, he hypothesized, "If I raise the temperature of a cup of water, then it will be able to dissolve more sugar."

Which of the following results would support the hypothesis?

A. The cup with the warmest water dissolved the largest amount of sugar.

B. The cup with the coolest water dissolved the largest amount of sugar.

C. None of these statements support the hypothesis.

D. The cup with the warmest water dissolved the least amount of sugar. Slide15

Question 14

Students in Mr. Painter's science class studied samples of pond water using a microscope. To prepare for the experiment, the students placed a drop of pond water on each microscope slide, and then covered the drop with a cover slip that was marked with a 1 mm grid.

Using the microscope to view the slides, students counted how many of each type of organism they found in each 1 mm square. Finally, each student calculated the total number of each type of organisms. Their data is shown below

.

Which organism is the least plentiful in the pond water studied?

A.

volvox

B. amoeba

C. paramecium

D. euglena Slide16

Question 15

Jeremy hypothesized that adults with blue eyes are shorter than adults with brown eyes. He collected data by visiting all of the teachers in his school and found that his hypothesis was false. Should Jeremy consider his hypothesis useful?

A. No; a false hypothesis makes a scientist look silly.

B. Yes; now he knows that the exact opposite of his hypothesis must be true.

C. Yes; a false hypothesis gives a scientist new information to use.

D. No; false hypotheses are a waste of time. Slide17
