Are you a sixth grader and have been having a hard time when it comes to the sciences? The quiz below is designed to help you review what you have learned in chemistry and physics class and intending to help you pass the final exams. Do give it a try and see how well you will do. Remember to share with classmates.

• 1.

### Length times width times height is the formula for finding what?

• A.

Volume of a irregular shaped solid

• B.

Area

• C.

Volume of a regular shaped solid

• D.

Mass

C. Volume of a regular shaped solid
Explanation
The formula length times width times height is used to calculate the volume of a regular shaped solid. This formula is commonly used for rectangular prisms, where the length, width, and height are all known. By multiplying these three dimensions together, we can determine the amount of space occupied by the solid. The formula is not applicable for irregular shaped solids, as their volume calculation requires different methods.

### What is the main source of energy in our solar system?

• A.

Wind

• B.

Geothermal

• C.

Nonrenewable

• D.

The Sun

D. The Sun
Explanation
The Sun is the main source of energy in our solar system. It emits vast amounts of light and heat through nuclear fusion, which powers all life on Earth. The Sun's energy is essential for photosynthesis, the process by which plants convert sunlight into chemical energy. It also drives weather patterns, ocean currents, and the water cycle. Additionally, solar energy is harnessed through solar panels to generate electricity for human use. Overall, the Sun plays a crucial role in sustaining life and powering various natural processes in our universe.

### All matter has mass and takes up

• A.

Room

• B.

Space

• C.

Time

• D.

Energy

B. Space
Explanation
The statement "All matter has mass and takes up space" is a fundamental concept in physics. Matter is made up of particles that have mass and occupy physical space. This means that matter cannot exist without occupying a certain amount of space. Therefore, the correct answer is space.

### A word that means the same as transformation is

• A.

Energy

• B.

Mechanical

• C.

Thermal

• D.

Change

D. Change
Explanation
The word "change" is the best synonym for "transformation" as it refers to the process of becoming different or altering in some way. It encompasses a broad range of meanings and can be used to describe various types of transformations, such as physical, chemical, or even emotional changes. Therefore, "change" is the most appropriate word that carries a similar meaning to "transformation".

• 5.

### Which of these is an example of a physical change?

• A.

Melting ice

• B.

Rusting metal

• C.

Browning fruit

• D.

Tarnishing silver

A. Melting ice
Explanation
Melting ice is an example of a physical change because it involves a change in the state of matter from solid to liquid, without altering the chemical composition of the substance. The molecules in ice rearrange themselves when heated, causing the solid ice to transform into liquid water. This change is reversible, as the liquid water can freeze again to form solid ice.

### How long does it take for fossil fuels to form?

• A.

Weeks

• B.

50 years

• C.

Millions of years

• D.

Every other weekend

C. Millions of years
Explanation
Fossil fuels are formed from the remains of plants and animals that lived millions of years ago. Over time, these remains were subjected to heat and pressure, causing them to undergo chemical changes and transform into the fossil fuels we use today, such as coal, oil, and natural gas. This process takes an extensive amount of time, spanning millions of years, which explains why fossil fuels are considered non-renewable resources.

Rate this question:

• 7.

### Which would be an example of a mechanical to thermal energy transformation?

• A.

Running fast and stopping

• B.

• C.

Singing in the shower

• D.

Explanation
Rubbing your hands together is an example of a mechanical to thermal energy transformation. When you rub your hands together, the friction between them generates heat energy, converting the mechanical energy of the hand movement into thermal energy. This process is known as mechanical friction, where the mechanical energy is transformed into thermal energy due to the resistance between the surfaces in contact.
