Day Eighty Three Overview
- we started class with some acceleration practice problems in the note packet as well as another acceleration worksheet
- after the students were done with those practice problems we started working on another acceleration worksheet
Acceleration Practice
Motion Worksheet #2 - Page 1
Motion Worksheet #3 - Page 2
- the best way to learn acceleration problems is for the students to be immersed in the topic
- after the students were done working on the practice problems we went over them as a class
- we then watched a brain pop clip that helped to finalize the concept of acceleration and what it means

- I then quickly introduced graphing speed and acceleration to the students, and how the graphs corresponded to what they were learning in the motion unit
Homework
- finish the odd numbers on the assigned acceleration practice worksheet

Day Eighty Two Overview
Day Eighty Two Overview
- students finished working on their hot wheel labs
- this took approximately half of the period
- with the second half of the period we began to take notes on the concept of acceleration
- it was explained that acceleration is when velocity changes
- that can mean when a speed goes up or down or when something changes direction
- this is because velocity is speed AND direction
- I emphasized to the students that something can be still moving without accelerating
- this can happen when the object stays going the same velocity
- I also showed the students a simulation that allowed the students to watch a person moving on the Smartboard along with a graph being generated along the way
Homework
- work on finishing up the Hot Wheels Lab

Day Eighty One Overview
Day Eighty One Overview
- we began class by taking a quiz based on the material we have been learning in class for the last week or so
- the students were asked to identify the formulas used to find speed, distance and time
- the students were also asked to explain what a reference point is and why it is important
- the students were then asked to solve a few problems where they were supposed to apply their knowledge of the formulas
- after taking the quiz the students began working on a lab where they were asked to calculate the speed of hot wheel cars at a number of distances
- we turned the classroom into a racetrack and marked the floor with various distances
- using stopwatches the students took times and calculated the speed of their cars

Day Eighty Overview
Day Eighty Overview
- we warmed up by trying to determine what the fastest thing they could think of would be, excluding the speed of light
- I told the winning group that they would get free homework passes
- the winning group came up with a shooting star as the fastest thing they could think of
- a shooting star moves at up to 160,000 miles per hour
- we then finished our speed notes
- after finishing up the speed notes we worked as a class on the last set of practice speed problems
- we went over the answers to the problems as a class
Homework
- study for your quiz
- work on the second section of their guided reading

Day Seventy Nine Overview
Day Seventy Nine Overview
- I began class by having the students work in pairs to develop their own speed word problems
- the students were asked to come up with 2 word problems per group, and each problem was to be solved for either speed, distance, or time
- they could not be solving for the same thing in both problems
- after developing the word problems the students were asked to swap papers with other groups so they could complete the other class problems
- the students were asked to complete one problem from 2 different groups
- after the warm up activity we went over the homework worksheet
- after going over the homework we took some brief notes on what it means to combine velocities
- I asked the students "If you are in a bus traveling 15 m/s east, and you get up and walk down the aisle of the bus going the opposite direction as the bus, are you still traveling 15 m/s east?"
- after some debate the students began to understand that you would actually be traveling slightly slower than the bus because you are moving with a small velocity in the opposite direction
- the last 5 minutes of class the students were able to get a start on their homework
Homework
- Speed Machines worksheet

Day Seventy Eight Overview
Day Seventy Eight Overview
- we began notes on speed and velocity
Motion Powerpoint For Notes
- one of the key points for students to remember is that speed has no direction and velocity always does
- besides that, they are both calculated the same way
- in addition the students were taught the basic speed formula (v = d/t)
- they were given a triangle with the three variables in the speed formula to help them manipulate the formula and find other values besides just speed or velocity, depending on what they are given in a problem
Homework
- finish the "Triangle" speed worksheet
