Grade 1 Energy Sources — Printable No-Prep Worksheet

This ready-to-use worksheet helps first-grade students identify the energy sources that make objects move. Through a simple classification task, learners will distinguish between motion caused by people power and motion caused by fuel. It provides focused, visual practice for foundational physical science concepts, making abstract ideas about energy concrete and accessible for young students.

What's Inside

This two-page PDF includes a student worksheet and a corresponding answer key. The main activity presents nine illustrations where students must identify the energy source—people or fuel—by circling or boxing the image. A final question encourages critical thinking about energy consumption. The layout is clean and the instructions are simple, enabling independent work.

Zero-Prep Workflow

This print-and-go worksheet is designed for efficiency. The entire process from printing to student work can take less than two minutes, making it perfect for a science warm-up, substitute plan, or exit ticket. The workflow is simple: print the single page for each student, distribute, and let them begin. The intuitive design requires minimal explanation, saving valuable teaching time.

Connecting to Science Standards

This activity builds foundational knowledge for physical science inquiries and aligns with Next Generation Science Standard K-PS2-1. The standard focuses on investigating pushes and pulls. This worksheet supports that goal by helping students identify the energy source behind those forces. The standard code can be easily copied into lesson plans or curriculum maps.

Flexible Classroom Use

Use this resource as a pre-assessment before an energy unit or as an independent practice activity after a lesson. It also functions as a quick formative assessment; observe students to see which examples cause hesitation, informing your next instructional steps. Most students can complete the tasks in 10-15 minutes.

For Early Elementary Scientists

Created for first graders, this worksheet uses clear visuals to support early readers and ELLs. The task is straightforward, making it accessible for independent science center work. For added support, complete the first two items together as a class. Pair it with an anchor chart of energy sources to reinforce the concept.

This worksheet provides focused practice on a key physical science concept for early learners, aligning with standard K-PS2-1. By having students classify objects based on their energy source—people or fuel—the activity builds foundational understanding of pushes, pulls, and the energy required to cause motion. This type of explicit skill categorization is critical in early science education, where abstract concepts must be grounded in concrete examples. Research from Fisher & Frey (2014) emphasizes the importance of purposeful tasks that allow students to apply concepts independently after guided instruction. This resource serves as that independent application step. It enables teachers to quickly assess whether students can differentiate between human-powered and fuel-powered motion, a building block for later NGSS standards on energy transfer and forces. The task's design reflects findings on effective science instruction, prioritizing clear, observable phenomena to build student understanding from the ground up.
