Magnitisim

Writing assignment #2

In our investigations my group and I have done my experiments with positive and negative magnetic charges. We observed things like what would happen when a wool cloth was rubbed against a plastic rod, what would happen if a silk cloth was rubbed against a glass rod, and what all those different things did with a pith ball. We used different models to test out theories. So now we will go threw the steps of science of science inquiry to see what we have so far.
      In step one of our science inquiry, me and my group observed many different things. We saw what happens when we rubbed the wool cloth to the glass rod and the rod to the pith ball. Our group tested what would happen if we rubbed a wool cloth to a plastic rod and touched it to a pith ball. Another thing our group observed was what would happen when a glass rod was rubbed with silk and brought to a plastic rod rubbed with wool.
The second step in our inquiry was the data that we collected. Everything we saw in our observations we collected for data. The results of both the rods were very alike. The glass and plastic rod both pulled the pith ball then shot it away. We also saw that the plastic rod rubbed with the wool attracted the pith ball but once we rubbed the glass rod with the silk it pushed the pith ball away
Our third inquiry was the models and theory making we used. We started off at first with model one which was the one charge model. We saw that the rods both had a charge and did similar things but it was till the two charge model we saw what the different charges we actually doing. So in theory the one charge model says charge does not want to go to an object that already has charge. The two charge model comes back with negative charge repels other negative charges. To prove this we go on to experimenting this.
The fourth science inquiry is experimentation. Our group tested out these theories on the two models and this is how: the first thing we did was the one...
