VOCABULARY
A vocabulary word means a statement that can be checked by an experiment
testable
The engineering reason that does this: "People want to customize smartwatches, so different watch faces and watch bands were created."
meet societal demands
what step in the scientific method is this: Why do plants grow better in some locations than others?
Ask a question
Which step in the engineering problem is: Our team sketched three different bridge designs and researched which materials are strongest. We looked at real bridges online to see how engineers solve similar problems.
Explore ideas
Find out how long it takes for a ice cube to melt.
clock, stopwatch
A vocabulary word describes data that are numbers, like mass or length
quantitative
An engineering reason that show this Read: "A heart rate monitor added to a smartwatch increases the number of tools available on the smartwatch."
Improve technology
Which part of the scientific method is: I placed 12 plants in two different locations: six by the window and six in a dark corner. I watered each plant with the same amount of water every day for four weeks and measured their heights weekly.
Procedure/Experiment Design
Which part of the engineering process is: We need to build a bridge that can span 2 feet across a gap and hold at least 50 pounds without breaking or bending more than 1 inch.
State the problem
Find the width of your classroom.
meter stick
A vocabulary word that describes observations using senses (not numbers)
qualitative
An engineering process that shows: "Smartwatches are now water resistant so they are less likely to be damaged during regular wear."
Decrease risks
Which step in the scientific method is: I predict that plants exposed to more sunlight will grow taller than plants with less sunlight because sunlight is needed for photosynthesis.
hypothesis
Which part of the engineering process is: We created detailed blueprints showing the exact dimensions, materials needed, and step-by-step instructions for building our bridge prototype.
Deisgn a plan
Pour exactly 250 milliliters of liquid into a container.
graduated cylinder
A vocabulary word that means a factor that limits how you can design something (for example, time or space)
constraints
Give one sentence that explains why adding a heart rate monitor could both improve technology and meet societal demands.
teacher approval****
which part of the scientific method is: Looking at my data, I noticed that all the plants by the window grew taller than all the plants in the corner, and the difference increased each week.
Analyze the results
Which part of the engineering process is: We built our bridge out of popsicle sticks and wood glue, then tested it by placing weights on it until it collapsed. It broke at 30 pounds, which was less than our goal of 50 pounds.
Build and test
Determine if one container holds more liquid than another.
measuring cup or graduatd cylinder
A vocabulary word that means a rule or requirement a design must meet
criteria
Describe a real-world constraint that might prevent an engineer from making a smartwatch thinner.
teacher approval****
which part of the scientific method is: I will present my findings to the class using a poster that shows my data and conclusions.
share my results
Which part of the engineering process is: We noticed our bridge failed because the joints weren't strong enough. We redesigned it by adding diagonal support beams and using stronger adhesive between the pieces.
Analyze and redesign
Determine if a box of cereal weighs more than a box of crackers.
pan balance
