SCIENCE QA! REVIEW Questions

A student places an cherries and a pineapple on a balance pictured to the left. What can the student conclude by reading the balance?

• The cherries is heavier than the pineapple.

• The pineapple is heavier than the cherries.

• The cherries and pineapple weigh the same.

• The balance is broken.

A student is classifying objects shown based on their physical properties. Which property can be used to classify these objects into two groups?

• magnetism

• relative density

• physical state

• electrical conductivity

Students completed an investigation to help them classify objects. They moved objects from one container to another to see if the object's shape changed. Which state of matter will take the shape of the container?

• Solid

• Liquid

• Gas

• Plasma

Students constructed this table to show physical properties of the objects they tested. The heading for the physical property in the last column is missing. Which heading belongs in the last column?

• not attracted by magnet

• conducts thermal energy

• insulates electricity

• solid physical state

Students poured water and cooking oil into a beaker. The students then added a marble, a plastic button, and a cork to the beaker and recorded their observations. Observations: - The water was on the bottom, and the oil was on top of the water. - The marble dropped to the bottom of the beaker. - The plastic button floated on the water but under the oil. - The cork floated on top of the oil. Which list puts the items in order from most dense to least dense?

• Marble, Water, Plastic Button, Oil, Cork

• Cork, Oil, Plastic Button, Water, Marble

• Plastic Button, Marble, Water, Oil, Cork

• Oil, Cork, Marble, Water, Plastic Button

A student puts four objects in a bucket filled with water. The objects are listed below: stick, golf ball, metal ring, cardboard. Which two objects are more dense than water?

• Stick and golf ball

• Golf ball and metal ring

• Metal ring and cardboard

• Stick and cardboard

A student compares the physical properties of the objects shown. What property do they have in common?

• less dense than water

• attracted to magnets

• conduct thermal energy

• soluble in water

The plug is a good insulator and conductor because:

• It is made of materials that conduct electricity well.

• It has a design that prevents electrical flow.

• It combines conductive and insulating materials effectively.

• It is used in electrical circuits.

Which of the following objects is the more dense than water?

• plastic domino

• steel paper clip

• copper wire

• paper confetti

Which of the following objects is the less dense than water?

• plastic domino

• steel paper clip

• copper wire

• paper confetti
