Loops are used to simplify the implementation of repeating commands.
The agent can place blocks in any of 4 directions.
Frequency is defined as the number of waves that pass a point per second.
A wavelength is the distance between the crest of each wave.
Amplitude is the vertical distance between a crest or trough and the equilibrium point.
This activity is best completed by individual students, or students working in pairs.
With the help of their agent, students are to examine the model wave found at the spawn point. They will also discover 4 empty “posters” of different sizes, each with an equilibrium point across the center.
Challenge students to expand on the sample code attached to the model wave poster and create four new posters that meet your expectations. For example, students might be asked to code their agent to:
Students will likely use the agent move and place commands but should be allowed to discuss and experiment with options.
Some of the empty posters are taller and some are wider to support trial and error.
Slabs (half-sized blocks) are used in the example wave, but students may want to experiment with full-sized blocks.
At the end of this activity, students will have produced four examples of waves.
Students will be able to identify wavelengths .
Students will be able to define amplitude .
Students will be able to identify which model has the highest and lowest frequency.
Students should be able to answer the following questions:
