CloudLabs Balancing the Seesaw

In this laboratory practice, you are going to use measuring instruments such as the ruler and the balance, in order to balance the "seesaw" game. To do so, the weights of three (3) random pieces that added together equal 500 g will be used. The same amount of weight will be placed at the other end of the game. Then, you have to measure the pieces and place them correctly on a shelf located in the classroom.
