Chemistry is full of tools like scales, and cylinders, and such. We used a scale to measure mass, and a graduated cylinder to measure the mass. The lab was kind of fun but we had to do calculations to see how much percentage we were off in guess the mass and volume.. For homework we had notes on the scientific method, and i thought of it as something you already know but dont know what it means until you see the definition. Yea i know confusing stuff but easy none-the-less. sooo thats what be happening in my Chem. class be bak l8r. PEACE FROM THE CHEESER!
