Question 1

As the Moon appears to get smaller in its progress, we say it is:​
A) ​waning.
B) ​full.
C) ​waxing.
D) ​crescent.

Accepted Answer

As the Moon appears to get smaller in its progress, we say it is waning.

Question 2

The time needed for a planet to make one complete turn around the Sun is:
A) one day.
B) one month.
C) one year.
D) one week.

Accepted Answer

The time needed for a planet to make one complete turn around the Sun is called its orbital period or its year. This is approximately 365.25 days for Earth, which is why we have a leap year every four years to account for the extra quarter day. Therefore, the best choice is C - one year.

Question 3

The design and production of structures, devices, and systems on the scale of an atom or molecule refers to the field of:
A) nanotechnology.
B) microbiology.
C) astronomy.
D) zoology.

Accepted Answer

The field of designing and producing structures, devices, and systems on the scale of an atom or molecule is known as nanotechnology. Therefore, option A - nanotechnology is the correct choice. Microbiology focuses on the study of microorganisms, astronomy deals with celestial objects and the phenomena that occur in the universe, and zoology relates to the study of animals in the animal kingdom, so options B, C, and D are incorrect choices.

Question 4

The scientist that discovered that all matter is made up of atoms too small to be seen was:
A) J.J. Thompson.
B) Niels Bohr.
C) Democritus.
D) John Dalton.

Accepted Answer

Democritus is credited with the idea that all matter is made up of atoms. While he did not have the technology to see atoms, he reasoned that they must exist based on his observations of the physical world. J.J. Thompson, Niels Bohr, and John Dalton made important contributions to the understanding of atoms, but they did not discover that all matter is made up of atoms too small to be seen.

Question 6

J.J. Thompson discovered that inside of atoms are negatively charged particles called:
A) electrons.
B) neutrons.
C) protons.
D) shells.

Accepted Answer

J.J. Thompson discovered the existence of negatively charged particles in atoms, which he named electrons.

Question 7

Mr. Johnston helped the students remember which fruit modeled which planet by making a:
A) key.
B) picture.
C) chart.
D) table.

Accepted Answer

A key would be the best choice as it is a simple and organized way to display which fruit represents which planet. A picture, chart, or table could also work, but a key is the most direct and clear option.

Question 11

As the Moon appears to get bigger in its progress, we say it is:
A) waning.
B) waxing.
C) new.
D) crescent.

Accepted Answer

When the Moon appears to get bigger in its progress, it is said to be waxing.

Question 12

In order to adapt the edible Solar System model for early elementary, the author suggests:
A) having the students memorize the order of the plants.
B) watching videos on the Solar System.
C) using precut circles to represent the relative sizes of the planets.
D) focusing on the gravitational forces on each planet.

Accepted Answer

Using precut circles to represent the relative sizes of the planets is the best choice for adapting the edible Solar System model for early elementary students. This allows for students to visualize the varying sizes of the planets in a tactile and interactive way. Memorizing the order of the planets or focusing on gravitational forces may be too advanced for this age group, and while videos can be helpful, they may not provide the same level of engagement and understanding as a hands-on activity like cutting and arranging different-sized circles.

Question 13

An oval shape with no center but with two points of reference called foci is:
A) an orbit.
B) an asteroid.
C) an ellipse.
D) a satellite.

Accepted Answer

An oval shape with two points of reference called foci is an ellipse. Orbits can also be elliptical, but the term "orbit" is too general and does not specifically refer to the shape. Asteroids and satellites can have various shapes and are not specifically defined by having two points of reference.

Question 14

Stars shine by:
A) producing light.
B) loosing mass.
C) spinning.
D) moving closer and further from the Earth.

Accepted Answer

Stars shine by producing light through nuclear fusion reactions in their cores. This produces energy that is radiated outwards in the form of light and heat.
