1.

  What instrument do you need to be able to see a microorganism?

Answer: Microscope
Explanation:
To be able to see a microorganism, you need a microscope. A microscope is a scientific instrument that magnifies small objects, allowing us to see them in detail. Unlike a telescope or binoculars, which are used to observe distant objects, a microscope is specifically designed for viewing tiny organisms such as bacteria, viruses, and other microscopic life forms. It uses a combination of lenses and light to magnify the specimen, making it visible to the human eye.
2.

What do antibiotics do?

Answer: Kill bacteria that cause disease
Explanation:
Antibiotics are medications that are used to kill bacteria that cause disease. They work by targeting specific bacteria and inhibiting their growth or destroying them completely. This helps to eliminate the infection and alleviate the symptoms associated with it. Antibiotics are not meant to help bacteria grow, but rather to combat bacterial infections and restore health.
3.

  What are forces measured in?

Answer: Newtons
Explanation:
Forces, which are pushes or pulls acting on an object, are measured in the SI unit called the Newton (N). This unit is named in honor of Sir Isaac Newton, the scientist who formulated the laws of motion. A Newton is specifically defined as the amount of force needed to accelerate a mass of one kilogram at a rate of one meter per second squared. In mathematical terms, it is expressed as 1 kg·m·s^-2. This definition helps standardize the measurement of force, making it consistent and universally understood in scientific and engineering contexts.
4.

What instrument can I use to measure forces?

Answer: Force meter
Explanation:
A force meter is a tool specifically designed to measure forces. It is equipped with a spring or other mechanism that can be compressed or stretched by the force being measured. By measuring the deformation of the spring or mechanism, the force meter can accurately determine the magnitude of the force. A telescope and microscope are used for observing distant objects and magnifying small objects, respectively, while a thermometer is used for measuring temperature.

What will happen if I have two magnets and I put both the north poles together? 

Answer: The magnets will repel
Explanation:
If you put the north poles of two magnets together, they will repel each other. This happens because like poles of magnets repel each other while opposite poles attract. The magnetic fields of the north poles interact in such a way that they push away from each other, creating a repulsive force. This principle of magnetic repulsion is a fundamental aspect of magnetism and is used in various applications, such as magnetic levitation and in designing electric motors where controlling the attraction and repulsion between magnetic poles is crucial for operation.
6.

  What will happen if I have two magnets, and I put one north pole on one magnet next to a south pole on the other magnet?

Answer: The magnets will attract
Explanation:
If you put the north pole of one magnet next to the south pole of another magnet, they will attract each other. This occurs because opposite poles of magnets attract each other. The magnetic field lines from the north pole of one magnet connect with the magnetic field lines of the south pole of the other magnet, creating an attractive force that pulls the two magnets together. This principle of magnetic attraction is fundamental to magnetism and is used in various applications, such as in the design of magnetic locks, compasses, and other devices that rely on the alignment of magnetic fields.
7.

  What is the force that pulls us downward to Earth and stops us from floating into space?

Answer: Gravity
Explanation:
Gravity is the force that pulls objects towards each other. It is responsible for keeping us grounded on Earth and preventing us from floating into space. Gravity is a fundamental force of nature that exists between all objects with mass. It is the reason why objects fall when dropped and why the planets orbit around the sun. Without gravity, everything would be weightless and there would be no stability in the universe.
8.

What is the force that slows down a man falling out of a plane with a parachute?

Answer: Air resistance
Explanation:
Air resistance is the force that slows down a man falling out of a plane with a parachute. When an object moves through the air, the air molecules push against it, creating a resistance force. This force opposes the motion of the object and causes it to slow down. In the case of a person falling with a parachute, the large surface area of the parachute increases the air resistance, allowing the person to descend at a slower rate. Without air resistance, the person would fall much faster and potentially be injured upon landing.
9.

Which of these forces slows you down if you ride a bike on the grass instead of on smooth pavement?

Answer: Friction
Explanation:
When riding a bike on grass instead of a smooth pavement, the force that slows you down is friction. Friction is the resistance that opposes motion when two surfaces come into contact with each other. The uneven and softer surface of grass creates more friction compared to the smooth pavement, causing the bike to slow down. Air resistance, gravity, and upthrust do not directly affect the bike's speed in this scenario.
10.

How fast does light travel?

Answer: 300,000,000 meters per second
Explanation:
Light travels at a speed of approximately 299,792,458 meters per second (m/s) in a vacuum. This is roughly equivalent to 300,000 kilometers per second (km/s) or about 186,282 miles per second (mi/s). This speed is commonly referred to as the speed of light, denoted by the symbol 𝑐c, and is a fundamental constant in physics. It represents the maximum speed at which information or matter can travel through space. The speed of light is crucial in various fields of science and technology, including telecommunications, astronomy, and the theory of relativity.
11.

What surface would be the best at reflecting light?

Answer: A shiny surface
Explanation:
 A shiny surface would be most suited to reflecting light because it has a smooth and polished texture that allows light to bounce off it easily. The smoothness of the surface reduces the scattering of light, resulting in a higher degree of reflection. In contrast, a dull surface has a rough texture that causes light to scatter in different directions, reducing the overall reflection. A scrubbed surface may have some reflective properties depending on its smoothness, but it would not be as effective as a shiny surface. An opaque surface, by definition, does not allow light to pass through it, so it would not reflect light effectively.
