Today we took up the homework from last Thursday (#3, 4 on p. 155). We then reviewed how to graph distance-time data and how to use that graph to find the average speed of the object (=slope of the line of best fit). Students then completed an activity involving graphing distance-time data and finding slope. Tomorrow we will be graphing our tobogganing data.

On Friday we gathered tobogganing data. We measured the time of the sleds at 2m intervals down a slope. On Monday, you will be graphing the data for the 3 sleds and using the graphs to find the average speed of each sled. Remember a few of you still need to get forms signed and all of you have 2 homework questions to do (#3 and 4 from the distance-time graphs section). Have a nice weekend!

Today we discussed instantaneous speed vs constant speed. There was a note and then students answered #1-3 from p. 153. They then copied a note about distance-time graphs. We practised graphing and finding slope. Please answer #3 & 4 on page 155 by Monday. Remember to bring a toboggan tomorrow for our speed lab. Also, dress for cold weather...hat, mitts, snowboots!

Today students had the whole class to practice solving speed problems. They used the "GRASS" problem solving method to solve questions 2-6 on page 149. We took these problems up at the end of the class.

Today we practiced converting units, such as meters to kilometers, hours to seconds. We then went over the "GRASS" problem solving method and practiced a few speed problems. Tomorrow, students will solve several speed problems on their own.

Today we began to complete an outline on the motion unit. The first three terms on the back of the sheet were completed (distance, time, speed). We then began copying a note on Measurement and Calculations. This will continue tomorrow.
