The single motor movement block is the first in the blue Motors section.
This block moves only one motor for a certain amount. It has four settings:
The first one is the port where the motor connects to the hub.
The second one is the direction you can set it to go forward or backward. If you set the amount of movement to negative, that will also change the direction, so be careful which method you're using!
The third one is the amount of movement, where you can set how long you'd like your robot to move.
The fourth one is the measuring unit of the movement, which has three options: rotations, degrees, and seconds. One rotation is a full circle of the motor and equals 360 degrees. Seconds is a less accurate option because it doesn't care if the motor has reached its endpoint. All it does is measure the time. It's useful when the motors get stuck while moving for degrees or rotations.

Level A2 - History and Mythology - Robotics with LEGO SPIKE Prime
This is the second level of the LEGO Robotics Curriculum for second, third, and fourth-grade students.
In this level, we will focus on History and Mythology, with each lesson covering a different aspect of the ancient world. You will learn about a new distance sensor that uses ultrasound to help a watchtower robot detect invaders. We will also introduce new concepts such as loops, degrees, and a third motor. Additionally, you will learn how robots can perform two different tasks simultaneously.

Lesson 1 - Ancient Boats
Introduction
In this lesson, we will learn how the ancient people managed to use the wind to navigate the seas, and we will build a boat robot!
People have used water for transportation for thousands of years. It was useful when you go downstream on a river or a sea current.
What do you think they did to go upstream?
They needed to use people with oars to fight against the current, which was really tiring and couldn't work for a long distance. So, people invented the first sailboats! They used the power of wind, which allowed them to go further faster, and they didn't need so many people to move them. The first record of a sailboat is a drawing on a vase in Egypt around 5500 years ago. However, sailboats were probably invented a long time before that.
The Phoenicians were the most famous naval people of the ancient Mediterranean world. They used their sailing boats to discover and trade with lands throughout the entire Mediterranean Sea, and even beyond, reaching as far as the British Isles. They became a massive trading empire and invented an alphabet, which was later the basis for the Greek and Latin alphabets we still use today!
Another people who mastered sailing around the same time were the natives of southeast Asia, who managed to sail all around the Pacific Ocean and reach even the furthest islands there.
