Cultural diversity refers to the different customs of a society, among which we can mention: clothing, cuisine, religious manifestations, traditions, and also the differences in languages, customs, accessories, utensils, lifestyles, values, and forms of artistic expression.
The main propagators of Brazilian culture are the European colonizers, the indigenous population, and African slaves. Later, Italian, Japanese, German, Polish, Arab, and other immigrants contributed to the cultural plurality of Brazil.
Cultural diversity enriches and develops societies, making it essential to value and protect it, promoting mutual understanding and respect.

• What do you understand by cultural diversity?
• Are there students of different ethnicities at your school? Do they have the same customs as you?

ACTIVITY PROPOSAL
WATERWHEEL
This is a type of large wheel, usually made of wood or metal, that turns with the force of water. It is placed in rivers, streams or canals, where the current pushes its blades or blades, making it move.
Its main function is to transform the energy of the movement of the water into mechanical energy, that is, into the force to perform some work. In the past, this force was used, for example: to move mills that ground grains and made flour, to pump water to plantations or houses and to generate energy in small hydroelectric plants.
The waterwheel is an old but very clever example of how people learned to use nature as a source of energy.
BUILD
As a team, build a prototype of a Water Wheel. Use the parts available in the structural robotics technology kit. Carefully follow each step of the assembly and testing. All members must actively participate in the process and contribute ideas and solutions.
CONTINUE
After building the prototype, share your experience with your colleagues and answer their questions.
• Was the base of the assembly stable?
• Would you have made the wheel blades differently when assembling it? How?
• What is the function of the gray connector fitting into the blue one?
Then, save all the materials used.
