Be Resourceful SG

Imagine Harper and Arjun are on a quest to find an __________, a magical natural resource that humans use to generate energy. But beware, it can be __________ if not used wisely!

• nonrenewable resource, depleted

• fossil fuel, replaced

• renewable resource, depleted

• fossil fuel, depleted

• renewable resource, replaced

Answer explanation

A nonrenewable resource is one that cannot be replenished in a short time frame, leading to its depletion. Fossil fuels are a type of nonrenewable resource that humans use for energy, making 'nonrenewable resource, depleted' the correct choice.

Hey Emma and Jackson, can you guess which type of processes replace renewable resources at least as fast as they are used?

• natural, quickly

• artificial, slowly

• natural, slowly

• artificial, quickly

Answer explanation

Renewable resources are replenished through natural processes that occur quickly enough to match their usage. This ensures sustainability, making 'natural, quickly' the correct choice.

Hey Liam, Emma, and Charlotte! Can you guess what fossil fuels release when they are burned? It's something that plants love!

• oxygen

• carbon dioxide

• nitrogen

• hydrogen

Answer explanation

Fossil fuels, when burned, primarily release carbon dioxide as a byproduct. This greenhouse gas contributes to climate change, making it the correct answer. The other options do not accurately represent the emissions from burning fossil fuels.

Imagine Ava and William are on a quest to discover the secret energy source that powers the sun! They learn that the energy released when the __________ of atoms are split or combined is called __________ energy. Can you help them fill in the blanks?

• electrons, electrical

• nuclei, nuclear

• protons, potential

• neutrons, kinetic

Answer explanation

The energy released when the nuclei of atoms are split or combined is known as nuclear energy. This process is fundamental in nuclear reactions, distinguishing it from other types of energy like electrical or kinetic.

Imagine you're in a science class with Hannah, Ethan, and Priya. The teacher asks, "What type of nuclear reaction powers the energy plants that light up our cities today?"

• fusion

• fission

• combustion

• evaporation

Answer explanation

Today's nuclear power plants use fission, a process where the nucleus of an atom splits into smaller parts, releasing a significant amount of energy. Fusion, on the other hand, combines nuclei, and is not currently used in power plants.

Hey science enthusiasts! Samuel and Lily are having a debate about nuclear fuels. Can you help them out? What is the most common nuclear fuel used today?

• coal

• uranium

• plutonium

• thorium

Answer explanation

Uranium is the most common nuclear fuel used today, primarily in nuclear reactors for electricity generation. It is favored for its abundance and efficiency in sustaining nuclear fission reactions.

Hey Henry, Elijah, and Harper! Can you guess in which three states of matter we can find fossil fuels? It's a bit like a treasure hunt through the elements!

• solid, liquid, gas

• liquid, plasma, gas

• solid, plasma, liquid

• gas, plasma, solid

Answer explanation

Fossil fuels can exist in three states of matter: solid (like coal), liquid (like oil), and gas (like natural gas). Therefore, the correct answer is solid, liquid, gas.

During a lively classroom debate, Lily asked, "What is another name for crude oil?" Can you help her out?

• petroleum

• gasoline

• diesel

• kerosene

Answer explanation

Crude oil is commonly referred to as petroleum. While gasoline, diesel, and kerosene are derived products from crude oil, the term petroleum encompasses the raw form of this natural resource.

During a science class, Oliver and Scarlett are debating about the main component of natural gas. Can you help them figure it out?

• Methane

• Ethane

• Propane

• Butane

Answer explanation

The main component of natural gas is methane, which typically makes up about 70-90% of its composition. Ethane, propane, and butane are present in smaller amounts.

Hey science enthusiasts! Grace, Evelyn, and Luna are curious: Why aren't we using nuclear fusion to power our power plants yet?

• It's too expensive

• It's not yet technologically feasible

• It produces too much waste

• It's too slow

Answer explanation

Nuclear fusion is not yet technologically feasible for power plants. While it has great potential, current technology has not advanced enough to make it a practical and reliable energy source.
