RI.5.3 Review Part 1

Do you love zipping a radio-control car through your kitchen? Have you seen people flying radio-control airplanes in a field? The science behind how remote-control toys work is interesting. Many of these toys are operated through radio control. Radio controlled toys are battery or gas-powered vehicles that can be controlled from a distance using a transmitter or remote.

What is a radio controlled toy?

• A battery-powered speaker that can be used to listen to music and talk shows

• A gas-powered vehicle that you drive or ride in

Do you love zipping a radio-control car through your kitchen? Have you seen people flying radio-control airplanes in a field? The science behind how remote-control toys work is interesting. Many of these toys are operated through radio control. Radio controlled toys are battery or gas-powered vehicles that can be controlled from a distance using a transmitter or remote.

What can you infer based on the underlined sentence?

• Radio-controlled cars are very large and must be used outdoors.

• Radio-controlled cars can only be used when connected to wi-fi.

• Radio-controlled cars are small and portable.

While there are differences in how radio-controlled toys operate, all of these toys have four main parts. The transmitter is the control you hold in your hands. It sends radio waves to the receiver. The receiver is an antenna and circuit board that is located inside the toy that gets signals from the transmitter, which initiates motors in the toy. The motors work to turn the wheels and steer the toy. All radio-controlled toys have a power source, which is typically batteries.

What are the four main parts that all radio-controlled toys have?

• Remote, Buttons, Motors, Power Source

• Transmitter, Receiver, Motors, Power Source

• Transmitter, Remote, Receiver, Motors

• Receiver, Motors, Wires, Power Source

The solar system is made up of eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. All of the planets orbit around the sun. Mercury’s orbit is the closest to the sun, and Neptune’s orbit is the farthest. You can use the sentence “My Very Educated Mother Just Served Us Nachos” to help you remember the planets in order. The first letter of each word in this silly sentence will remind you of the first letter of each planet.

TRUE or FALSE: Pluto is a planet in our Solar System.

• True

• False

The planets are divided into two groups: the inner planets and the outer planets. Mercury, Venus, Earth, and Mars are the inner planets. They are much warmer than the outer planets. Jupiter, Saturn, Uranus, and Neptune are the outer planets. The asteroid belt separates the inner and outer planets.

What is the relationship between the inner planets and the outer planets?

• The outer planets are warmer than the outer planets.

• The outer planets are colder than the outer planets.

• 
  The outer planets are closer to the sun than the inner planets.

• The outer planets are much smaller than the inner planets.

The planets are divided into two groups: the inner planets and the outer planets. Mercury, Venus, Earth, and Mars are the inner planets. They are much warmer than the outer planets. Jupiter, Saturn, Uranus, and Neptune are the outer planets. The asteroid belt separates the inner and outer planets.

According to this paragraph, where is the asteroid belt located?

• 
  In between the sun and the inner planets.

• On the outside of the outer planets.

• 
  In between the inner and the outer planets.
