1st Grade Science Question of the Day

1. The wide top catches water and the narrow bottom guides it in. (correct answer)
2. The funnel's bottom is wide so water sprays out.
3. The funnel is square so it can hold pencils upright.
4. The arrows mean Amir already built the funnel at home.

Explanation: This question tests the 1st grade skill of developing a simple sketch to show a solution to a problem, focusing on how the object's shape helps it function (K-2-ETS1-2: Develop a simple sketch to illustrate how the shape of an object helps it function as needed to solve a given problem). When designing solutions to problems, we sketch or draw our ideas to show what we're thinking. An important part of any design sketch is showing the shape of the solution and how that shape helps solve the problem. Different shapes do different jobs: flat shapes provide surfaces to place or stand on; shapes with edges or walls hold things in and prevent spilling or falling; shapes with dividers separate items into sections; round shapes roll or don't have corners; narrow shapes fit in tight spaces; wide shapes are stable. A good sketch shows the shape features that are important for making the solution work. In this scenario, Amir spills when pouring water into a small bottle. His sketch shows a funnel with a wide top and a narrow bottom and arrows going down. The key shape features shown are wide top narrowing to point. Choice A is correct because it accurately identifies the shape: describes the shape shown in sketch; correctly connects shape to function: explains how shape feature solves problem; identifies key functional feature: focuses on the shape element that makes solution work. For example, the wide top catches water and the narrow bottom guides it in. Choice B represents wrong shape feature: describes the shape incorrectly, like bottom is wide so water sprays out. This error typically occurs when students notice shape but don't connect it to function, focus on non-functional aspects of drawing, miss the key shape feature that solves problem, confuse what shape does, describe general shape without explaining how it helps, think any shape description is sufficient. To help students understand sketching solutions: Practice 'shape does job' connections (flat top - stand on it, edges - hold things in, dividers - separate items, holes - hold specific things, wide base - stable); have students sketch simple solutions and explain 'how does this shape help?'; look at real objects and identify functional shape features; emphasize that sketch should show the shape features that make it work, not just be pretty. Watch for: students who draw but can't explain how shape helps, who focus on decorative elements instead of functional shape, who describe shape without connecting to problem-solving, who miss the key functional feature in their description, or who think any shape will work without thinking about what shapes do. Key concept: the SHAPE of an object determines what it can do - we sketch to show and communicate what shape we need to solve the problem.
