Educational Use
Students work as engineers and learn to conduct controlled experiments by changing one experimental variable at a time to study its effect on the experiment outcome. Specifically, they conduct experiments to determine the angular velocity for a gear train with varying gear ratios and lengths. Student groups assemble LEGO MINDSTORMS(TM) NXT robots with variously sized gears in a gear train and then design programs using the NXT software to cause the motor to rotate all the gears in the gear train. They use the LEGO data logging program and light sensors to set up experiments. They run the program with the motor and the light sensor at the same time and analyze the resulting plot in order to determine the angular velocity using the provided physics-based equations. Finally, students manipulate the gear train with different gears and different lengths in order to analyze all these factors and figure out which manipulation has a higher angular velocity. They use the equations for circumference of a circle and angular velocity; and convert units between radians and degrees.

In this lesson, students explore equality using the equal sign. They will first explore equality with sets or groups using the equal sign then move to exploring equality with equations. The lesson could be taught consecutively in one math block but may need to extend over multiple days depending on student understanding of the concept of equality, or having equal amounts. The lesson could also be modified or extended by repeating tasks and discussion with more emphasis on subtraction.

This resource is from Tools4NCTeachers.In this lesson, students work with different quantities to determine if they have the same value / equal. The information is presented in a context, not simply in an equation format, so students will need to apply their understanding of problem solving and resulting equations along with computation in order to determine if the amounts are equal. Students will explain and defend their answers. This file includes lesson, student recording sheets, and printable exit tickets. Remix this lesson to include extension ideas or student work samples.
