Science 10 -  We reviewed the homework from the previous day on neutralization reactions. Students got their review as well as a copy of the review answers that they can use tonight to study from. All grade 10 science classes will be writing a test tomorrow covering rates of reactions as well as acids and bases. This is a much shorter test then the previous one and consists of 10 multiple choice questions and 5 short answer questions.   Science 9 - Students began examining meiosis today in class. Homework questions were assigned. Students will take part in recycling tomorrow and continue their examination of meiosis on Thursday with a look at non-disjunction and its potential consequences.
