Are You Smarter Than A Fourth-Grade Student?

A fourth-grade student is traditionally the turning point between learning to read and reading to know. Students must be able to accurately and automatically recognize words and word counts starting in the fourth grade. Many young people find the fourth grade to be an exciting year. Most fourth graders are 8 or 9 years old, and as they learn about the world, they strive for independence. Students in the fourth grade begin learning how to create reports using research methods.

How long does it take the earth to complete one revolution around the sun?

365 days

31 days

200 days

1 day

365 days
We’re starting simple, but don’t worry, they’ll get more challenging. Twenty-four hours make up a day on Earth (the time it takes the Earth to rotate or spin once). In 365.256 days, Earth completes one sun orbit, corresponding to one Earth year.

What exactly are germs?

Some individuals might believe germs are bugs, cookies, or other disgusting things. In reality, germs are microscopic organisms or living things that can infect humans and cause disease.

Which of these systems is in charge of your heartbeat?

Water

Motion

Electrical

Temperature

Electrical
Your heart’s electrical system sends signals to its walls to cause them to contract. Your circulatory system, a web of vessels that transports blood to and from the rest of your body, is pumped full of blood when the walls constrict.

What organ collaborates with your heart to provide oxygen to your body?

Brain

Stomach

Kidney

Lungs

Through the pulmonary arteries, the right side of the heart gathers and pumps blood to the lungs. The lungs give the blood a new supply of oxygen, which causes it to turn red.

Which benefit can a person receive from eating food?

Dark Matter

Daylight

Energy

Hyper

Energy
The body receives energy from the three primary nutrients: protein, carbohydrates, and fat. We need food because, without it, we would wither away.

What is the driving force behind any two objects moving in the same direction?

Weight

Gravity

Volume

Electricity

Gravity
Through gravity, a planet or other body pulls objects toward its center. All the worlds are maintained in their orbits around the sun by the force of gravity.

Which type of simple machine is illustrated by a Ferris wheel?

Wheel and axle

Fixed pulley

Lever

Incline plane

Wheel and axle
The first Ferris wheel was constructed in 1893 using more than 100,000 parts, including a 140-foot-tall axle weighing 89,320 pounds that had to be hoisted onto two towers. More than 1.4 million people paid 50 cents for a 20-minute ride over the following 19 weeks.

A hypothesis is what?

A result

A tentative assumption

An estimate

A scientific law

A tentative assumption
A hypothesis is a statement that has not been proven but is assumed valid for discussion, further research, or investigation. Then, through experimentation are evaluated.

What state of matter is water in when it has turned into ice?

Plasma

Gas

Jelly

Solid

Solid
Water freezes to form ice. Ice will weigh less than the same volume of water because when water freezes, its molecules separate more widely.

Describe migration.

Movement from one place to another

Aging

Change from one form to another

Hibernation

Movement from one place to another
For instance, animal migration is when an animal physically moves from one place to another, as the monarch butterfly and many different bird species do each year.

What tools are most effective for viewing cells?

Stethoscope

Periscope

Microscope

Telescope

Microscope
A microscope is a device that magnifies objects so that they can be seen up to 1,000 times closer than with the unaided eye. Zacharias Janssen created the first one in 1590.

The phrase “the building block of life” commonly applies to what microscopic organism?

Bacteria

Atom

Quark

Cell

Cell
Cells are the building blocks of all life. Humans are made up of roughly 37 trillion cells, whereas some are only one cell thick.

What do you call a creature that eats mostly meat?

Herbivore

Omnivore

Carnivore

Predator

Describe mass.

The amount of matter in an object

A solid material

Length

Weight

The amount of matter in an object
The object’s quantity of matter can be considered it’s mass in Newtonian physics. It is also the “m” in the well-known equation “e=mc2” by Albert Einstein.

To make a model volcano erupt, which of these should you add to baking soda?

Lava

Vinegar

Mentos

Oil

Vinegar
Baking soda and vinegar undergo a straightforward chemical reaction that increases the volume of the mixture and, in a fun and messy way, causes it to shoot out the top of your model volcano.

Which of the following best describes “protecting resources”?

Pollution

Agriculture

Conservation

Conservation
Conservation refers to the clever use and protection of a resource, including the planned management of wildlife and natural resources.

Which of these is a method for separating different metals from one another?

Sunlight

Evaporation

Magnet

Water

What is a form of rain, sleet, hail, and snow?

Fish

Precipitation

Transpiration

Gas

Precipitation
