Today is the seventh day in America. Today is a really exciting day, because we made a roller coaster. It was a little bit difficult, but I enjoyed making it. We spent all the morning making it, but we still didn't finish it. After lunch, we continued making it. We tested it over and over again. Then we got it.

After that, many people who were working at the Berkeley got here and looked at our posters of bridges and the roller coaster. To my joy I could talk to people who speak English more easily than before. We also gave a speech about study these days.

It's a really good day.
