Flashcard 1: Which option is a measurement you can collect when testing two bridges: color, length held, or name?
Answer: Length held. Length held is measurable; color and name are not.
Flashcard 2: What is the best tool to record test results for two designs in an organized way?
Answer: A data table. Tables organize data clearly for comparison.
Flashcard 3: What should the column headings include in a data table for two designs?
Answer: Design name and the measured result for each trial. These headings organize your test data clearly.
Flashcard 4: Identify what you should do immediately after each trial when testing two designs.
Answer: Record the result right away. Recording immediately prevents forgetting data.
Flashcard 5: Which option is the best way to compare two designs fairly: 1 trial each or 3 trials each?
Answer: 3 trials each. Multiple trials reduce the impact of random errors.
Flashcard 6: What is the meaning of a result in a design test?
Answer: The outcome you observe or measure from a trial. Results are the data from your testing.
Flashcard 7: Which option is qualitative data: “5 blocks held” or “bridge is wobbly”?
Answer: “Bridge is wobbly”. Qualitative data describes qualities, not numbers.
Flashcard 8: What is the best conclusion if Design A flew 6 m, 7 m, 6 m and Design B flew 4 m, 5 m, 4 m?
Answer: Design A performed better because it flew farther in all trials. All trials show Design A consistently flew farther.
Flashcard 9: Identify the dependent variable when testing which car design rolls farther.
Answer: The distance the car rolls. The dependent variable is what you measure as the outcome.
Flashcard 10: Identify the independent variable when comparing Design A and Design B for the same problem.
Answer: Which design is used (A or B). The independent variable is what you change on purpose.
Flashcard 11: Choose the word that names what must stay the same in a fair test: variable, constant, or conclusion.
Answer: Constant. Constants don't change; variables do.
Flashcard 12: Which design performed better if Design A held 8 coins and Design B held 11 coins?
Answer: Design B. Design B held more coins, showing better strength.
Flashcard 13: What is the meaning of qualitative data in a design test?
Answer: Describing words about what you observe. Qualitative describes qualities without numbers.
Flashcard 14: What is the meaning of quantitative data in a design test?
Answer: Number data you can count or measure. Quantitative means numerical and measurable.
Flashcard 15: Which option is quantitative data: “rolled 12 cm” or “rolled far”?
Answer: “rolled 12 cm”. Quantitative data includes numbers and units.
Flashcard 16: What is the meaning of data in a design test?
Answer: Information you collect during a test, such as counts or measurements. Data helps you compare which design works better.
Flashcard 17: What is the meaning of a design in an engineering test?
Answer: A planned way to make something that solves a problem. Designs are created solutions to specific problems.
Flashcard 18: What is the meaning of a fair test when comparing two designs?
Answer: A test where only the design changes and everything else stays the same. Fair tests isolate the design as the only variable.
Flashcard 19: Which option is a good variable to keep the same when testing two paper airplanes: thrower, design, or distance flown?
Answer: Thrower. The thrower must stay constant to test only the plane design.
Flashcard 20: What is the meaning of a trial in a design test?
Answer: One time you test a design and record the result. Each trial gives you one data point to analyze.
Flashcard 21: What is the purpose of testing two designs that solve the same problem?
Answer: To compare which design works better using evidence. Testing reveals which solution performs best through measurable results.
Flashcard 22: Which graphic best shows counts for two designs: a bar graph or a story paragraph?
Answer: A bar graph. Bar graphs visually compare numerical data between two designs.
Flashcard 23: Identify the correct comparison statement when A has 3 successes and B has 5 successes.
Answer: Design B had more successes than Design A. Compare success counts directly to determine better performance.
Flashcard 24: Design A landed in 5 seconds and Design B landed in 7 seconds. Which landed more slowly?
Answer: Design B. Longer fall time means slower descent for parachute designs.
Flashcard 25: Design A held 6 pennies and Design B held 4. Which design performed better in this test?
Answer: Design A. Higher penny count shows stronger bridge design performance.
Flashcard 26: Find the better conclusion method: pick your favorite design, or use recorded data to decide?
Answer: Use recorded data to decide. Evidence-based decisions rely on test results, not personal preference.
Flashcard 27: Choose the best data to collect when testing two parachutes: time to land or paper color?
Answer: Time to land. Parachute effectiveness is measured by fall time, not appearance.
Flashcard 28: Identify the correct way to record results: write from memory later, or write immediately after each test?
Answer: Write immediately after each test. Recording immediately prevents forgetting important observations.
Flashcard 29: Which choice makes a fair test: same ramp height for both designs, or different heights?
Answer: Same ramp height for both designs. Equal test conditions ensure results depend only on design differences.
Flashcard 30: Identify the best measurement to record for a paper bridge test: color or number of pennies held?
Answer: Number of pennies held. Measurable data like weight capacity shows design performance clearly.
