Science Quiz

Elijah is conducting an experiment. The water level in a graduated cylinder rises from 25 mL to 30 mL when a marble is added. What is the volume of the marble? Record your answer to the nearest whole number and fill in the bubbles.

Ava and William want to find out how the water temperature in their home aquarium changes throughout the day. What should they do to increase the reliability of their results?

• Use a new thermometer every day

• Measure the temperature of the water multiple times every day for many days

• Compare the temperature of the water with the air temperature

• Make sure to use gloves

On a hot summer day, Isla places a glass of ice water on the picnic table. Predict what will happen to the water vapor in the air around the glass of ice water.

• The water vapor will condense, and water droplets will form on the outside of the glass.

• The water vapor will evaporate.

• The water vapor will precipitate, and water droplets will form on the outside of the glass.

• The water vapor will melt into water.

Michael is conducting an experiment to separate mixtures. Which of these mixtures can he separate using a magnet?

• Sand and water

• Sugar and water

• Sand and iron

• Rocks and sand

While camping, Benjamin noticed that the Sun, his lamp, and the campfire all produce —

• electrical energy

• light energy

• mechanical energy

• solar energy

James is trying to decide whether to use a copper wire or a rubber tube to connect his new speaker system. Why is a copper wire a better conductor than a rubber tube?

• Copper lets heat move through it more easily than rubber does.

• Copper limits the amount of heat that passes through it more effectively than rubber does.

• Rubber lets heat move through it more easily than copper does.

• The particles in rubber are able to slide past one another, but the particles in copper cannot.

Emma is trying to turn on a light bulb using a battery and some wires. Which of the following needs to be true for the light bulb to light up?

• The electrical circuit has to be a series circuit.

• The electrical circuit has to be a parallel circuit.

• The electrical circuit has to be closed.

• The electrical circuit has to be open.

Mason, Scarlett, and Ava are working on a science project. They create three different electromagnets using identical iron cores, wires, and batteries. The first electromagnet has few coils. The second has more coils, and the third has even more coils. They count how many paperclips each electromagnet can pick up. Which question can most likely be answered with data from this investigation?

• How does increasing the current running through the wire affect the electromagnet?

• Does a larger iron core make an electromagnet stronger?

• How is an electromagnet different from a magnet?

• Do more coils make an electromagnet stronger?

Nora and Arjun want to determine how much force is required to pull a toy car across a desk. Which tool should they use?

• A - Spring scale

• B - Magnet

• C - Ruler

• D - Balance scale

Kai and Nora are conducting an experiment. Hypothesis: The force of gravity is stronger on heavier objects. Which experimental setup should they use to test this hypothesis?

• A

• B

• C

• D
