Tyler hangs a magnet from a string as shown in the picture. He then holds another magnet and moves it toward the magnet on the string. What will most likely happen to the magnet on the string?

• It will be attracted to the other magnet.

• It will stay in the same position.

• It will fall off of the string.

• It will move away from the other magnet.

• texture and weight

• color and hardness

• mass and volume

• volume and hardness

Collin is studying magnetic attraction in science class. His teacher has a collection of objects that have been displayed on a table. They are pebbles, plastic beads, iron nails, a key, and some pieces of aluminum foil. Which of these objects can Collin predict will be attracted to a magnet?

• steel key and iron nails

• iron nails and rocks/pebbles

• plastic beads and aluminium foil

Use the chart to answer the question.

Group B concluded that worms prefer light. The other groups concluded that worms prefer dark. Based on the chart, what might account for the difference in conclusions across the groups?

• Group B did not perform enough trials.

• Group B used different types of worms

• Group B did not have the same light source.

• Group B did not record accurate results.

Five groups of students followed the same procedure to test the effect of color on the temperature of water as shown in the illustration below...

The groups placed thermometers with the same starting temperature in each beaker. They measured the temperature change over a period of one hour. Groups A, B, C and E concluded that the temperature change happened faster with the black paper. Group D concluded that the temperature change happened faster with the yellow paper. What most likely accounts for the difference in their results?

• Group D failed to make a prediction before doing the experiment.

• Group D did not display their results in a chart or graph.

• Group D did not make accurate measurements.

• Group D had a smaller beaker than the other groups.

Miss Spencer’s class is growing corn seedlings for a science experiment. They measured the growth of corn seedlings and put their data in the bar graph shown.

Which of the following is an observation students might make about the corn seedlings?

• On Day 8, the corn seedlings reached a height of 12.5 cm.

• Corn seedlings need more water to grow taller.

• Corn seedlings prefer a warm and sunny place to grow.

• Corn seedlings will continue to grow after Day 12.

In Mr. Dorsey’s class four students each conduct the same investigation. Three of the students get similar results. Marina, the fourth student, has results that are very different from the other students. Which of the following is the most likely reason that Marina’s results are different from the other students?

• She made a different hypothesis

• She changed the procedures.

• She recorded and analyzed results.

• She took more time to do the experiment.

Lucas is describing the physical properties of two unknown substances. He puts his observations and measurements in the table below.

Which of the following is a conclusion that Lucas CANNOT make about the two samples?

• They have a similar hardness.
