EIGHTH GRADE SCIENCE
We will be finishing up the chemistry unit with a study of chemical reactions. Students will review chemical and physical properties, and changes as a review before we start the unit. Students will identify changes as physical or chemical using an online activity. Students will also carry out several investigations and label them as physical or chemical changes based on certain signs of chemical reactions. The Law of Conservation of Matter will be discussed and students will learn to balance equations. There will be numerous hands on activities to supplement the lessons on the types of chemical changes that occur during a chemical reaction. Students will also study endothermic and exothermic reactions. The chapter will end with a study of the factors that affect the rate of a chemical reaction.
Current Events-Each student will present a current event in science to the class. Students were given their assigned date to present their current event as well as directions and a rubric for the assignment. All current event grades will be posted in the 4th marking period, regardless of which marking period the student's assigned date is in.
The assignments for the week will be posted on PowerSchool. Please keep in mind that the assignments that I post are based on my plans for the week. Plans are subject to change, and therefore the dates that assignments are due may change. Your child’s assignment book should be the most accurate location for assignments and due dates. The assignments are listed ahead of time on PowerSchool so that you can get an idea of what we are doing.
