Today in the lab, we were investigating how the size of the magnet affects its strength.
By doing this lab we learned that we need to have controlled variables. Initially,
we believed that the bigger the magnet the more strength it would have. The
following materials were needed to complete this lab: three different size magnets,
paperclips, and a ruler. These were the steps we followed: First, we measured the
smallest magnet by seeing how close the magnet has to be to pull the paperclip.
Second, we measured the medium magnet the same way. Third, we did the
same for the largest magnet. Finally, we recorded our data. The data shows that
the smaller the magnet is the stronger the magnetic force. This data does not support
our hypothesis. The smaller the magnet the further away the paperclip would be
attracted. One difficulty we encountered was human error such as fingers getting in
the way of the magnet. One group's data was similar to ours because they had the
same type of magnets as us. However, the other three groups had different results due to
using a different type of magnet. If we were to do this lab again, we would have the
same type of magnets for each group.
Did your results follow the trend from small to large? Or was the medium magnet weaker than the smaller and larger magnets? When you write up your materials and methods you need to add more detail so that if someone else were to repeat your experiment they would do it exactly the same way. Good job on the additional discussion section!
Your graph should have both the x and y axis labeled and give your chart a name.
