DE 3rd Grade Science Curriculum
Give your child the support they need to keep up with Delaware's 3rd grade science curriculum, from ecosystems and food chains to forces, simple machines, and earth materials.
About 3rd Grade Delaware science
Delaware follows the Next Generation Science Standards (NGSS), organizing 3rd grade science around life science, physical science, and earth and space science strands. This course covers ecosystems, adaptations, food chains, energy pyramids, forces, simple machines, thermal energy, landforms, earth materials, the solar system, human impact, climate, and the engineering process. StudyPug provides video lessons and practice problems aligned to each strand so students can review topics at their own pace.
- Strands: ecosystems, adaptations, forces, earth materials, solar system, and engineering process
- Video lessons for every 3rd grade science topic
- Practice problems and step-by-step explanations aligned to NGSS
- Parent assignments and smart recommendations to track progress
Curriculum topics by strand
Lessons and practice for every strand, aligned to the Delaware NGSS-adopted science standards.
Delaware 3rd Grade Science Topics
- Advanced Investigation and Foundation Review: Scientific inquiry skills, observation, and data collection that underpin all other strands.
- Ecosystems, Adaptations, and Food Chains: How living things interact with their environment, how organisms adapt to survive, and how energy moves through food chains.
- Energy Pyramids: How energy is transferred and lost at each level of a food chain.
- Forces and Simple Machines: Pushes, pulls, and how simple machines make work easier in everyday life.
- Thermal Energy: Heat transfer, temperature, and the ways thermal energy affects matter.
- Landforms, Earth Materials, and Climate: The features of Earth's surface, the rocks and minerals that make it up, and how climate shapes landscapes.
- Solar System and Human Impact: Earth's place in the solar system and how human activity affects the natural world.
- Engineering Process and Traditional Practices: How engineers define problems and design solutions, including knowledge passed down through traditional practices.
How StudyPug Helps Delaware 3rd Grade Science Students
When a Delaware 3rd grader gets stuck on a concept like energy pyramids or the engineering process, StudyPug lets them go back to the exact lesson they need and watch it as many times as necessary. Practice problems with step-by-step explanations reinforce each idea right after the lesson, which mirrors the way science is taught in class. You can explore grade 3 science help to see the full range of topics available.
Parents can use the parent assignments feature to see where their child is spending time and where they may need extra support. If your child is moving from 2nd to 3rd grade, the de grade 2 science curriculum page shows the prior-year content, and the de grade 4 science curriculum page shows what comes next.
Aligned to Delaware 3rd Grade Science Curriculum
Delaware has adopted the Next Generation Science Standards (NGSS), and all StudyPug 3rd grade science content is built around those same disciplinary core ideas, science and engineering practices, and crosscutting concepts. That means every lesson your child watches and every problem they practice maps directly to what their Delaware teacher is covering in class.
