Engineering Design Bridge Challenge
Buster the dog needs a bridge: a 2nd grade engineering challenge to define the problem, choose materials, sketch a design, and improve it after a test.
NGSS K-2-ETS1: asking questions, making observations, and gathering information to define a simple problem that a new or improved tool could solve.

Buster the dog needs a bridge: a 2nd grade engineering challenge to define the problem, choose materials, sketch a design, and improve it after a test.

2nd grade engineering matching: pair five everyday problems with tools such as a sponge and a step stool, then define a classroom problem a new tool could fix.

Label the parts of scissors, from the pointy tip to the oval handle, and say how each shape helps: a 2nd grade engineering worksheet for K-2-ETS1-2.

2nd grade engineering exit slip: students name a problem to fix, explain why a tool's shape matters, and rate the lesson on a five-face scale.

Guided notes for 2nd grade engineering: learn shape and function, sketch with labels, and design a way to carry six library books through the rain.

Paper bridge vs stick bridge Venn diagram for 2nd grade: sort nine test results, such as 50 pennies held and a bend at 10, into each design or both.
K-2-ETS1-1
“Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.”
K-2-ETS1-2
“Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.”
K-2-ETS1-3
“Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.”
