In class we learned about waves and tides. A wave is a rhythmic movement that carries energy through matter or space. Idividual molecules move up and down and causes the waves. Tides deppend on waves. The rise and fall is called a tide and its caused by giant waves.
Presentations about our careers were very interesting. Some of those careers seem fun and exciting. The career that interested me the most was mammal training because the animals seem very friendly when trained well. I saw some great presentations.
