STRESS this week. This week I had a lot of homework. I did not go to swim practice this whole week. Also, the pool heater broke, so we would have to go to San Mateo High School. Today, I had six tests in seven classes. Next week is finals week. I have to study very hard. In chemistry, I saw a video about mole, which is Amadeo Avagrado's number. It was a song sang by Mr. Olson and Mr. Washington. Mr. Washington was a physics teacher at Mills. Mole is 6.02 x 10^23 atoms. The molar mass is on the periodic table. It is the atomic mass of the isotopes of elements. I learned how to convert moles to number of atoms to grams. Dead week is not dead because I learned a lot during this week.
