Students learned how to determine forces and the SI unit. We also talked about the different units that make up a Newton. Then, we reviewed Newton's 1st Law of Motion, introduced the 2nd Law of Motion as well as explained the relationships. We concluded class by working practice problems in newton's 2nd Law of motion (acceleration, force and mass) They were given a word problem WS on newton's 2nd Law of Motion for classwork due 4th pd.
Chemical Reactions
Students began taking notes from the Power point on Chemical Reactions. Students learned what a chemical reaction is, how it is represented and ways to prove it took place.
Chemical Reactions
Students used the textbooks to answer questions from the Chapter on Chemical Reactions (60 pts).
Forces
Students used the textbooks to answer questions from the Chapter on Forces and Newton's Laws of Motion (60 pts). They were reminded to bring their calculators to class daily.
Observation / Density Lab
4-3-18 (Tuesday)
Students conducted an "Observation" Lab using the scientific method. Milk, food coloring, vegetable oil, water, and dishwashing liquid were used to observe the action of polar and nonpolar molecules. They were to also answer questions from the Data sheet (60 pts).
4-4-18 (Wednesday)
Students conducted a "Density of Irregular Solids" Lab. After discussing the ways to calculate volume and instruments used, students measured the mass of nuts, bolts, and washers using the methods of displacement, graduates and triple beam balances. Finally, after determining masses and volumes, students determined the density of the metals items.
Speed Lab
4-3-18 (Tuesday)
Students went outside and performed the Speed/Acceleration Lab. Students walked & ran 10 yds and 40 yds. They also went through walking 20yds and running 20yds w/out stopping to determine acceleration. We wrote the information on the data sheet in preparation for the actual calculations of speed and acceleration on Wednesday. Students received a bronze grade (10 pt) for bring their calculators to class. They were advised to have a calculator every day as stated in the syllabus.
4-4-18 (Wednesday)
Students were able to take the times and determine their speeds in walking/running 10 yds and walking/running 40 yds. We worked 3 problems on the board and explained the process of calculating speed. Finally, we went over the process of how to determine acceleration in 2 practice problems. We went over each item on the worksheet and students were given the data sheet (100 pt) and questions to complete at home for homework.
VSEPR
Students conducted a lab using balloons to represent the VSEPR theory on covalent bond and electrons. They completed the data sheet and were advised to dress correctly for labs on Tuesday and Wednesday of this week.
Forces / Motion
Students completed the Forces Vocabulary (30 pts) in class. They began the Forces & Motion Review Questions (60 pts) also. At the conclusion (last 10 min.) we discussed tomorrows lab and what we will be doing. They were advised to dress appropriately and have a calculator for tomorrows lab.
Covalent Compounds
Students took the Covalent Compounds Voc. Test (48 pts), we went over the answers, then they took the Covalent Compounds Chapter Test (100 pts) w/formulas given on the board. No Homework!!!
Motion
Students took the Motion Voc. Test (26 pts), we went over the answers, then they took the Motion Chapter Test (100 pts) w/formulas given on the board. No Homework!!!
