This middle school science bundle includes a 34 slide powerpoint that introduces speed, velocity, average speed, and instantaneous speed. Also included is an inquiry based lab using rotocopters.The powerpoint guides students through calculating speed from word problems. The rotocopter lab asks students to predict what happens when the size and shape of the rotocopter are altered. Students then gather data on distance and time to answer the inquiry questions. Great for a middle school science class to help students understand the variables, see terminal velocity "in action," or as a back to school lab that gets students up and moving and measuring and thinking :)
The powerpoint contains:
• Three different models for speed:
o strobe photos
• sample word problems to solve for speed, distance, and time
• a discussion of the differences between velocity and speed
• a discussion about differences between average speed and instantaneous speed.
At the end of the powerpoint, there are five "check yourself" slides that review the content and offer the opportunity for further discussion - perfect for informal formative assessments!
The five check yourself slides are followed by slides giving the answers. The worksheets are geared to both problem solving and a conceptual understanding of speed.
One worksheet is geared toward the content of the powerpoints (specifically, modeling/problem solving/vocabulary) and the other two worksheets are problem-solving worksheets. Additionally, I have included one of my super-popular speed logic puzzles.
All worksheets (and the puzzle) come with answer keys.
The rotocopter lab:
The rotor copter lab is a simple but effective lab where students create rotor copters and investigate the factors that affect the roto copter's falling speed. I've used this lab as an introduction to measuring speed, and I've also used it to introduce air resistance and terminal velocity when learning about acceleration due to gravity.
This lab requires little in the way of supplies: Included in this product are both the model template and instructions. Students will need the template, a pair of scissors, a paper clip, and a timing device. Also included are student instructions if you want to do the lab in a guided fashion and a more open-ended sheet if you prefer to have your students approach this lab as an inquiry-based activity.
All of my powerpoints include animations so that you may isolate important points with a single mouse click or tap on your whiteboard and avoid the dreaded, "head-down, madly-copying, not-listening" powerpoint syndrome :)
This bundle would be appropriate as a first introduction to speed in a middle school physical science class or a 9th-grade physics class.
As a preview, I have created a pdf file with various parts of this unit so that you can determine if it will meet your needs.
