How Shape Helps Function - 2nd Grade Science

What shape feature helps a model handle be easy to hold: curved grip or sharp corners?

Curved grip. Curves fit the hand's natural grip for comfort and control.
Which shape helps a model straw move liquid: long hollow tube or short solid block?

Long hollow tube. Hollow tubes create a pathway for liquid flow.
What shape feature helps a model roll smoothly across the ground: flat face or round edge?

Round edge. Curved surfaces reduce friction for smooth rolling motion.
What does it mean when a model is described as having a shape that helps it function?

The model's shape supports the job the real object must do. Shape must match the purpose or job of the real object.
Which shape is commonly used in strong frames because it does not easily change shape: triangle or square?

Triangle. Three fixed points create a rigid, unchangeable structure.
Identify the best shape for a model wheel to roll smoothly: flat square or round circle.

Round circle. Circles roll smoothly because they have no corners.
What shape feature helps a model object stay still on a table: flat bottom or curved bottom?

Flat bottom. Flat surfaces create stable contact with supporting surfaces.
What shape feature helps a model umbrella block rain: wide curved top or thin straight rod only?

Wide curved top. Wide curved surfaces deflect rain away from underneath.
Which shape helps a puzzle piece model fit: edges that match or random edges?

Edges that match. Matching edges interlock pieces together.
Which model shape is best for a ramp that must move a toy car down: slanted or level?

Slanted. Inclines use gravity to create downward motion.
What shape feature helps a model bridge hold weight: triangle supports or circle supports?

Triangle supports. Triangles distribute weight evenly and resist deformation.
Identify the best shape feature for a model that must fit into a matching hole: same outline or different outline?

Same outline. Matching shapes allow pieces to fit together precisely.
Which shape helps a helmet model protect a head: curved shell or thin flat sheet?

Curved shell. Curved shape deflects impacts away from head.
What does it mean when a model's shape helps it function as needed?

The model's form is chosen to do a specific job well. Shape determines how well something performs its intended task.
Identify the shape feature that helps a model screw hold materials: spiral threads or smooth sides.

Spiral threads. Threads grip materials by creating friction.
Which word names the job an object is meant to do: shape, function, or color?

Function. Function describes what something does or its purpose.
Which shape is best for a model wheel that must roll: sphere or cube?

Sphere. Spheres have no edges, allowing continuous rolling motion.
Which shape helps a cup model hold water without spilling: tall sides or no sides?

Tall sides. Sides create a container to prevent liquid escape.
Which word names the outline or form of an object: shape, function, or weight?

Shape. Shape refers to the form or outline of something.
Which shape helps a model bridge support weight: triangle supports or loose curved string?

Triangle supports. Triangles distribute weight evenly and resist bending.
Which shape helps an umbrella model shed rain: curved top or flat top?

Curved top. Curved surfaces make water run off edges.
What shape feature helps a model pencil write: pointed tip or wide flat end?

Pointed tip. Points concentrate force for marking on paper.
Which shape helps a model door knob be easy to turn: round shape or sharp jagged shape?

Round shape. Round shapes are easy to grip and rotate.
Which shape helps a model parachute slow falling: large canopy or small solid ball?

Large canopy. Large surface area creates air resistance to slow descent.
Which shape helps a ramp model move objects down smoothly: slanted surface or bumpy surface?

Slanted surface. Slanted surfaces use gravity to move objects downward.
Which shape helps a funnel model guide liquid into a bottle: wide top and narrow bottom or flat top?

Wide top and narrow bottom. Wide opening catches liquid; narrow end directs flow.
Which shape helps a spoon model hold liquid: bowl-shaped end or flat end?

Bowl-shaped end. Curved shape creates a pocket to contain liquids.
Which model shape helps a boat float and stay stable: wide bottom or narrow point?

Wide bottom. Wide bottoms provide stability and buoyancy in water.
Which word names a shape feature that helps a model work: color, size, or structure?

Structure. Structure refers to how parts are arranged to create function.
What shape feature helps a model bowl hold items without spilling: deep curved sides or flat top?

Deep curved sides. Curved sides contain items and prevent spilling.
Which shape is best for a model roof that lets rain run off: triangle or flat rectangle?

Triangle. Sloped sides direct water away from the structure.
Which shape feature helps a model key fit a lock: matching grooves and edges?

Matching grooves and edges. Precise shapes ensure only the correct key operates the lock.
What shape feature helps a model shovel move dirt: wide flat blade or tiny round bead?

Wide flat blade. Flat blades efficiently push and lift loose materials.
Which shape helps a model ramp move objects downward: slanted surface or vertical wall?

Slanted surface. Slanted surfaces let gravity pull objects downward.
Identify the shape feature that helps a spoon scoop: flat surface or curved bowl end.

Curved bowl end. The curved bowl shape holds and lifts food.
Which shape is best for stacking blocks without rolling: cube or sphere?

Cube. Flat faces prevent rolling and provide stable stacking surfaces.
Which shape helps a shovel model dig: wide flat blade or round ball end?

Wide flat blade. Flat blade cuts through soil more effectively.
What shape feature helps a model shovel scoop material: curved scoop or flat stick?

Curved scoop. Curves hold and lift materials better than flat surfaces.
Which option best describes why a model's shape matters: color, shape, or name?

Shape. Shape determines how well a model performs its intended task.
Which shape is best for a wheel model to roll: circle or square?

Circle. Circles have no corners, allowing smooth rotation.
What shape feature helps a model boat float and stay balanced: wide bottom or narrow bottom?

Wide bottom. Wider bases provide more stability and buoyancy in water.
Which shape helps a model key fit a lock: matching ridges and grooves or smooth round stick?

Matching ridges and grooves. Specific ridges and grooves fit only one lock.
Which shape helps a model cup hold liquid: open top with tall sides or completely flat disk?

Open top with tall sides. Tall sides contain liquid while the open top allows filling.
Identify the shape feature that helps a model funnel guide liquid: wide opening to narrow tube.

Wide opening to narrow tube. This shape channels liquid from wide to narrow opening.
Which shape feature helps a model ramp move objects downward: slanted surface?

A slanted surface. Angles create slopes that use gravity to move objects.
Identify the best shape for stacking blocks in a model tower: cube or sphere.

Cube. Flat surfaces of cubes stack stably.
What shape feature helps a bridge model hold weight: flat deck or pointy deck?

Flat deck. Flat surfaces distribute weight evenly for stability.
What is the best first step to explain how a model's shape helps it function as needed?

State the function, then connect it to a specific shape feature. Start with purpose, then explain which shape achieves it.
Which shape helps a straw model move liquid: long hollow tube or solid rod?

Long hollow tube. Hollow tubes allow liquid to flow through.
Which shape helps a boat model float and stay stable: wide bottom or narrow bottom?

Wide bottom. Wide bases provide stability and buoyancy in water.
Which shape is best for a model container that must hold many small items: bowl shape or flat plate?

Bowl shape. Curved sides prevent items from spilling out.
