Grade 4 engineers focus on choosing the right tools and identifying variables in fair tests. Nine fill-in-the-blanks cover stopwatches, scales, prototypes, hypotheses, and goggles, while a matching task pairs tools with their measurement jobs. Grade 4 students learn that good data starts with good tools and that fair tests change only one variable at a time. Builds essential measurement vocabulary needed for every classroom engineering challenge.

Engineering Design Challenges
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A stopwatch measures how long something takes during an engineering trial.
2. A scale measures how heavy an object is in grams or pounds.
3. Recycled materials like cardboard and bottle caps are great for cheap prototypes.
4. A prototype is a first model engineers build to test their design idea.
5. In a fair test, only one variable is changed at a time so results are clear.
6. A safety goggles protect eyes from glue, paint, or flying small parts.
7. Hot glue guns melt sticks of plastic to bond materials quickly.
8. A simple table helps an engineer record results from each trial in order.
9. Before testing, engineers write a hypothesis predicting what will happen.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
