Current Events in FE8A

In these last few weeks we have been using Pythagorean theorem in math and in science we've been building electric cars, some worked better than others. Also we have got a new project with Foster money incorporated in to it.

In math, the basis of the Pythagorean theorem is: a²+b²=c², which says that a squared plus b squared is equal to c squared. In this case a, b, and c are all variables of side lengths, if you don't have c you can use the theorem to find it.
An example would be:
From here we would do:
a²+b²=c²
(5cm)²+(10cm)²=c²
25cm²+100cm²=c²
125cm²=c²
√125cm²=√c²
11.180339887498948482045868343656cm= c
11.18cm =c
Also remember to show all of the decimals shown on the screen then round.

In science we have a new project to create a machine that will draw ground water, represented by a 250g weight, from the ground and pull it up and down as many times possible in 2 minutes. The width of the hole is 10cm and the depth is 74cm. In this project we use our Foster money to buy supplies such as motors ($3000). This is going to be expensive.
