Distance Rate and Time for Math/Science/Physics
By Teacher Librarian Colleen Graves and Aaron Graves.
Appropriate for grade levels 8th to HS
Hooking up Makey Makey to Track
Use the Makey Makey to effectively time your car's speed- Students will use this Scratch game (or create their own game) to record the amount of time the car travels over a given distance.

Logging Distance, Time, and Slope
Students can use this chart or create their own to log the dedicated distance, changes in slope, time of travel, and added weight for each experiment.
Students will need to log the time for each car trip and hit the green flag to reset the time. They can run as many experiments as you desire.
Utilizing Distance Formula to find Rate
The Scratch game has a formula built in and is programmed to run the equation 10 times.

Note on Standards
These lessons were developed with the idea that teachers all over the globe and a variety of grade levels could hack the lesson plan to meet their students' needs. Therefore, these are just some of the standards the lessons are based on, and not an all-inclusive list. Many of the CCSS align by grade level, so if you teach 9th grade, you could find the stair-stepped standard for CCSS.ELA-LITERACY.W.8.6 by looking at CCSS.ELA-LITERACY.W.9-10.6.
CCSS.MATH.CONTENT.8.EE.B.5: Understand the connections between proportional relationships, lines, and linear equations.
CCSS.MATH.CONTENT.HSN.VM.A.3: Solve problems involving velocity and other quantities that can be represented by vectors.
CCSS.MATH.CONTENT.8.EE.B.5: Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.
CCSS.MATH.CONTENT.8.EE.C.7: Solve linear equations in one variable.
4-PS3-1: Use evidence to construct an explanation relating the speed of an object to the energy of that object.
4-PS3-2: Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
MS-PS3-1: Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.
HS-PS3-3: Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.
