Select the type of cloud that is high in the sky and made of ice. These clouds look very thin and wispy. 

Possible Answers:

Cumulus cloud

Altostratus clouds

Cirrus clouds

Stratus clouds

Correct answer:

Cirrus clouds

Explanation:

In order to answer this question correctly, we need to be able to decipher between the different clouds in the answer choices:

Altostratus clouds are found in the mid-level of the sky and made of ice crystals and water. Stratus clouds are typically gray and usually cover the entire sky.

Stratus clouds are low in the sky and look similar to fog that doesn't touch the ground, but does cover the entire sky. 

Cumulus clouds are white, puffy clouds. They resemble cotton balls in the sky. 

Cirrus clouds are high in the sky and made of ice. These clouds look very thin and wispy. 

The correct answer is cirrus clouds.

Example Question #1 : Physical Science

What causes a handle of a pot to be hot when a pot is heating on a stove? 

Possible Answers:

Conduction 

Energy 

Transmission 

Physical Properties 

Correct answer:

Conduction 

Explanation:

Let's look at the terms from our answer choices to help us answer this question:

Physical properties are things that can be observed; such as, texture, color, etc. 

Energy is the ability to do something. 

Transmission is when energy passes from one object to another.

Conduction is when heat is transferred from one object to another object. 

When a pot is heating on a stove, the pot is in direct contact with the heat source. The handle of the pot is in contact with the pot, and the heat can be transferred from the pot to the handle, which causes the handle to be hot. 

Example Question #3 : 3rd Grade Science

Select the property that is not a physical property. 

Possible Answers:

Weight

Texture 

All options are correct

Color 

Correct answer:

All options are correct

Explanation:

Physical properties are properties that can be obtained without permanently changing the original substance. By looking at something, we can see the color, feel the texture, and measure the weight without changing the substance; thus, all of the choices are correct. 

Example Question #2 : Physical Science

Select the property that is not a physical property. 

Possible Answers:

Heat of combustion 

Freezing point 

Boiling point 

Melting point 

Correct answer:

Heat of combustion 

Explanation:

Physical properties are properties that can be obtained without permanently changing the original substance. Without changing a substance permanently we can measure the boiling point, melting point, and freezing point. However, to determine heat of combustion you must premaritally change the substance.  

Example Question #3 : Physical Science

Fill in the blank. 

__________ is the frequency of sound that determines the highness or lowness of the sound. 

Possible Answers:

Volume

Neither volume or pitch 

Pitch 

Both volume and pitch

Correct answer:

Pitch 

Explanation:

To answer this question correctly, we need to determine the difference between volume and pitch:

Volume is a measure of how loud a sound is.

Pitch is the frequency of a sound that determines the highness or lowness of the sound.

Pitch is the correct answer. 

Example Question #1 : 3rd Grade Science

Select the answer choice that is not a basic need of a human. 

Possible Answers:

Schooling 

Shelter 

Food

Water

Correct answer:

Schooling 

Explanation:

Basic needs are things that people need to survive. In order to survive, people require food, water, shelter, and clothing. Though schooling is an important benefit to help people be successful, it is not needed for survival. 

Example Question #1 : Life Science

Select the part of the plant that keeps a plant in the ground and absorbs water and nutrients. 

Possible Answers:

Leaves

Stems

Flowers

Roots

Correct answer:

Roots

Explanation:

The answers choices provide various parts of a plant:

Roots keeps a plant in the ground and absorbs water and nutrients.

Stems provide support for plants and carry water and nutrients from the roots to the leaves. 

Leaves are where the food is made in a plant. 

Flowers are essential for seed creation. 

The correct answer is roots.
