Teacher's notes: Introduction to the lesson Pro Preview

The teacher should first explain the mission to the students: the robot should start from the base, marked in advance, to reach the next line, where the Moon is marked, to go round the Moon and return to the base.

Then the teacher should remind students that they have to accomplish the mission in small steps. Discuss with them what these steps might be.Students’ first task will be to accomplish the mission in which they have a starting and a final point set by the teacher. They should do that by trial and error until they find the correct settings of the robot. It all comes to trying out various settings for power and duration.

The same applies to setting the turn. Students will have to test both the angle and the duration of the turn.

Students should be careful about the sequence of the actions and, most importantly, should find a working solution on their own.

The teacher could make the task more complex: When the robot reaches the dark side of the Moon, it stops, makes a sound resembling the sound from a camera flash and then returns home.

The robot is horizontal. "I took the risk and it turned out great – I put a camera in the self-timer mode on top of the robot. At the start of the program I set a two-second delay, so that we could start the robot and install the camera on top". (Alex)

The teacher should tell students how robots turn in advance. He comments on programming the turn. The most obvious way is to use the tank block. The teacher should also focus on the steering block. You can also use the pictures in the m2 section.

For this lesson you will need a field, with some sort of marking for the Moon. This could be a pile of tires or a ball fixed to the floor somehow. You will also need to mark the pozition of the Earth where the robot will take off from. It could be a line of duct tape or a spacing between two floor tiles
