Today we learned how to make a compass with everyday materials. the materials we used to make the compass work was: water, pin, magnet, leaf and an container. the first step was to fill your container 2 cm deep with water. second step was to put an leaf at the top of the water gently so it does not sinks. third step is to grab your magnet and your pin and scrap your pin aside the magnet not to hard tho for 3 minutes. then once the 3 minutes is done you take the pin and carefully place it on top of the leaf make sure it does not sink and wait till it has stopped moving then your done the compass should face to where north is
objects such as keys, tables with metal legs, steel screws, phones and even heavy framed spectacles. High voltage power lines, car bodies and flashlight batteries will impact the compass too. Really anything that is built with steel metal or power.

It's an equation where you multiply all your numbers in the equation and then you would divide it by the amount of numbers that are in the equation.
The middle number; taking all numbers and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). Example: 6, 2, 5 when you put it with these numbers the answer would be 5 cause when you put it in order the number 5 is in the middle.
The mode is the number that is most common in the equation. The most in the equation is where you count all of your numbers and whatever number is the most common ( see the most) is your answer if you are doing a text or those type of equations ( Mode equations)
