Henri’s dad was moving cars out of his family’s driveway. The driveway

was located in strong sunlight. Henri observed that the family’s white car

was cooler inside than the family’s black car. He wants to do an

experiment to see whether color makes a difference in the amount of

radiant energy a metal surface absorbs. What should he do next?

• analyze evidence

• draw a conclusion

• plan an experiment

• communicate results

Ama wants to make potholders as gifts for her friends. She needs to know

the color of each person’s kitchen so she can choose potholder loops to

match. What skill will Ama use to find out the kitchen colors?

• draw conclusions

• make a prediction

Elena is planning an experiment. These are the procedures, or setups,

she plans to use. Which part of her plan will make it difficult for Elena to

draw a valid conclusion?

• She is testing more than one variable.

• She is using identical flowerpots

• She did not include a prediction of what will happen.

• She should use bean seeds rather than bean seedlings

Lila did an experiment to see whether saltwater or freshwater evaporates

more quickly. She put a jar of each type of water on her desk. Every day

she recorded the amount of water left in each of the jars. Why was it

important for Lila to keep records of the progress of her experiment?

• so she can show that she is a good scientist

• so other people can tell if she misses any days

• so she will know whether anyone knocks over one of the jars and spills the

  water

• so her results can be compared to those of others doing the same

  experiment

Dee did an experiment to test how long it took a cup of vanilla ice cream

to melt if the room temperature is 68°F. Quan repeated Dee’s

experiment. What is the best reason for Quan to repeat Dee’s experiment?

• to get the same results

• to be sure Dee’s time is accurate

• to move the ice cream to a different location in the room

• to see whether it takes the same time for chocolate ice cream to melt

Sue and Conrad did the same experiment. They got different results. What

should they do?

• combine their results

• do the experiment again

• flip a coin to choose one of the results

• ask their teacher to choose the best results

Juan releases a toy car at the top of a ramp and measures how far it goes.

He repeats this for ramps of different heights, then makes a graph to show

his results.

A scientific method is a set of steps used in many scientific investigations.

The steps are not always the same, nor are they always done in the same

order. Which of these steps in a scientific method best describes what

Juan is doing?

• Make a prediction.

• Organize data from observations.

• Identify variables for an experiment.

• Repeat an experiment to confirm results.

Andrew is investigating forces. He attaches a spring scale to a

box partly full of sand. He thinks that friction will keep the box

from moving. He pulls on the spring scale. It shows that force is

being used, but the box does not move.

A scientific method is a set of steps used in many scientific investigations.

The steps are not always the same, nor are they always done in the same

order. Which of these steps in a scientific method best describes what

Andrew is doing?

• Test a prediction.

• Organize and display information.

• Repeat an experiment to check results.

• Identify the variables for an experiment.

Greta is comparing magnets by counting the number of metal paper clips

each magnet picks up. She thinks that some magnets are stronger than

others because the magnets don’t pick up the same number of paper clips.

A scientific method is a set of steps used in many scientific investigations. The

steps are not always the same, nor are they always done in the same order.

Which of these steps in a scientific method best describes what Greta is doing?

• Make a prediction.

• Form a conclusion.

• Organize and display information.

• Repeat an experiment to check results.
