Quarter 1 Science Quiz

Charlotte, Ava, and Aiden are having a debate about the three states of matter. Can you help them settle the argument?

• plasma, liquid, gas

• solid, liquid, gas

• solid, liquid, plasma

• solid, gas, plasma

Arjun, Sophia, and Emma are having a debate about the formula for density. Can you help them settle the argument?

• Density = Mass x Volume

• Density = Mass - Volume

• Density = Volume/Mass

• Density = Mass/Volume

Ethan, Harper, and Benjamin are having a debate about the pH range for acids. Can you help them settle the argument?

• 0 to 14

• 1 to 7

• 0 to 6.9

• 7 to 14

Abigail, Zoe, and Kai are having a debate about the pH range for bases. Can you help them settle the argument?

• greater than 7

• equal to 7

• between 0 and 7

• less than 7

Kai, Anika, and Samuel are discussing different types of changes in matter. They come across the term 'physical change'. What is a physical change?

• A physical change is a change in the form or state of matter without any change in its chemical composition.

• A physical change is a change in the color of matter.

• A physical change is a change in the taste of matter.

• A physical change is a change in the smell of matter.

Imagine Ava, Henry, and Avery are in a science lab. They are experimenting with different substances and suddenly, a new substance is formed! What would you call this process?

• This is a chemical change, a process that results in the formation of new substances with the same properties as the original substances.

• This is a chemical change, a process that results in the formation of new substances with no properties.

• This is a chemical change, a process that results in the formation of new substances with different properties from the original substances.

• This is a chemical change, a process that results in the formation of new substances with opposite properties from the original substances.

Anika, Samuel, and Aria are having a debate about mixtures in their science class. Can you help them settle it? What exactly is a mixture?

• Samuel thinks a mixture is a combination of two or more substances that are chemically bonded together.

• Anika believes a mixture is a single substance that cannot be separated into its components.

• Aria argues that a mixture is a type of pure substance that has a fixed composition.

• Or, is a mixture a combination of two or more substances that are not chemically bonded together, as suggested by their teacher?

Nora, Noah, and Jackson are having a debate. Nora says a pure substance is made up of only one type of particle or molecule. Noah thinks it doesn't have any particles or molecules. Jackson believes it's a mixture of different substances. Who is correct?

• Nora, who says a pure substance is made up of only one type of particle or molecule.

• Noah, who thinks a pure substance doesn't have any particles or molecules.

• Jackson, who believes a pure substance is a mixture of different substances.

• None of them are correct.

Imagine Mia and David are having a debate. Mia says that when a solid is heated, its particles move further apart and expand. David, however, disagrees. According to him, which of the following could be his argument?

• David could argue that the particles in a solid remain in the same position.

• David could argue that the particles in a solid break apart and disintegrate.

• David could argue that the particles in a solid move closer together and contract.

• David could argue that Mia is correct and the particles in a solid do move further apart and expand.

Imagine Mason, Ethan, and Abigail are tiny particles in a liquid. What happens to them when the liquid is cooled?

• Mason, Ethan, and Abigail remain at the same speed and distance from each other.

• Mason, Ethan, and Abigail slow down and come closer together, forming a more ordered arrangement (condensation).

• Mason, Ethan, and Abigail speed up and move further apart, forming a less ordered arrangement (evaporation).

• Mason, Ethan, and Abigail change into a solid state (freezing).
