BRIDGE:Today in Math we are going to be doing an activity involving a ball and measurements!
TEACHER OBJECTIVES:To teach algebra implicitly using a Kinematics Lab.
STUDENT OBJECTIVES:Basic understanding of algebra and the ability to apply it to real world situations involving simple kinematics (v=d/t).
PRE-TEST:Intentionally none done, as we don't want to "tip our hat".
PARTICIPATION:Two tables.
1)The first table is a "Kinematics Shout-Out", where the students derive the basic Kinematics equations and put them in algebraic notation. We will be using the equation v=d/t and solving for the variables v, d, t using repetition.
2)The second table is a "Mini-Lab" with a ball rolling a set distance against a wall. The students will measure the distance from a line to the wall, and measure the time it takes the ball to get to the wall. This will then later be applied to the equation learned previously.
Required Materials:
- Masking tape
- Measuring tape
- Stop watches
- Balls
POST-TEST:Students will use their measurements and their new equations to calculate the speeds that the balls were rolling using v=d/t
SUMMARY:Surprise... you just learned algebra!
Write down the equation you learned and how you could apply this to another real life situation for next class.
