Flashcard: Axle vs. Distance

Step 3: Make a Hypothesis (claim)

Controlled Variable

Scientific Method

Iterative

Step 2A: Ask a Question

Engineering Design Process

Step 6: Write/Draw Conclusions

Independent Variable

Step 1: Identify the Problem

Step 2: Generate Concepts

Step 2B: Do Research

Scientific Method & Engineering Design Process

Step 1: Make observations about the natural world

Step 5: Analyze the Results of the Lab

Step 4: Perform an Experiment to answer the question

Dependent Variable

Step of the scientific method where we reviewed our observations of previous labs AND what we learned from them

Step of the Eng Design Process that this is: Design and build a mousetrap car that travels 1 tile in the fastest time

Step of the Eng Design Process that this is: Learning about mousetrap cars by doing an axle size vs. distance lab

A process that repeats a series of steps over and over

Used to come up with my own idea of a mousetrap car design that will travel 1 tile as fast as possible

The variable that we measure in an experiment

The variable that we make the same in an experiment or our results are effected/thrown off

The variable we make different in an experiment

Used to research how friction effects the speed of the mousetrap car by performing an experiment

Step of the scientific method where the question "How does the size of the axle effect the distance of the car?" was answered based only on our observations prior to performing the experiment

Step of the scientific method where we examined the data we collected in the lab to see which went farther: larger axle or smaller axle

Step of the scientific method where we wrapped up the MTCar with the smaller axle and the larger axle to see which went farther

Step of the scientific method where the question "How does the size of the axle effect the distance of the car?" was answered based only on our observations of this experiments results only: axle size vs. distance

Step of the scientific method where we identified a question to answer: How does the size of the axle effect the distance of the car?

The stepwise process that is iterative

Step of the scientific method where we learned about the concepts of applied forces, reaction forces, balanced forces, and unbalanced forces
