Part 1: What Engineers Do (Questions 1–5 • 50 Points) 10 pts each
1
Engineers draw a plan or sketch before they start building.
Why: Sketching helps engineers plan shapes and materials before using supplies.
TRUE
2
Testing a model helps you find out if your design solves the problem.
Why: Testing tests whether a physical prototype functions as planned.
TRUE
3
If a toy tower falls down during a test, engineers should give up and quit.
Why: A failed test shows what needs fixing so engineers can improve the design.
FALSE
4
A good engineer never changes their design after they test it.
Why: Iteration is central to engineering; testing guides improvements.
FALSE
5
An engineer's first idea is always perfect and never needs improvement.
Why: First ideas are starting points; real designs take multiple revisions.
FALSE
Part 2: What Scientists Do (Questions 6–10 • 50 Points) 10 pts each
6
Scientists ask questions about how nature and the world work.
Why: Science begins with curiosity and asking testable questions about the natural world.
TRUE
7
Scientists use tools like hand lenses and rulers to observe things closely.
Why: Scientific tools extend our senses to gather accurate measurements and details.
TRUE
8
Scientists only guess and never do experiments to test their ideas.
Why: Scientists conduct fair tests and experiments to collect evidence, not just guess.
FALSE
9
Scientists write notes and draw pictures to record what they observe.
Why: Recording data in science notebooks ensures observations can be reviewed and checked.
TRUE
10
Scientists keep findings a secret and never share what they learn with others.
Why: Scientists share findings with books, articles, and talks so other scientists can learn.
FALSE
Second Grade Science vs. Engineering Anchor Chart
Engineers: Ask: "What is the problem?" → Plan, design, build prototypes, and test solutions to solve human needs.
Scientists: Ask: "How does the world work?" → Observe, make predictions, do experiments, and gather data.
