Will this help with my child's 3rd grade science homework?

Yes. StudyPug covers every 3rd grade science topic in the California curriculum. Your child can search for the exact concept they are working on and watch a lesson or try practice problems right away.

How long are the video lessons for 3rd grade science?

Most video lessons are short and focused, typically running just a few minutes each. This keeps 3rd graders engaged and makes it easy to find help on one specific topic without sitting through a long session.

Is there a California state science test for 3rd grade?

California administers the CA Science Test (CAST) in grades 5, 8, and once in high school. Grade 3 is not a CAST testing year, so there is no statewide science assessment at this level.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and computers. Your child can watch lessons and complete practice problems from any device, making it easy to study at home or on the go.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can explore the content before subscribing. A 30-day money-back guarantee is also included, so there is no risk in getting started.

3rd Grade Science

About 3rd Grade California science

California follows the California Next Generation Science Standards (CA NGSS), which are organized around three dimensions: Disciplinary Core Ideas, Science and Engineering Practices, and Crosscutting Concepts. In 3rd grade, students explore life science, physical science, and earth and space science topics such as inheritance and traits, weather and climate, and forces and motion. StudyPug provides video lessons and practice problems aligned to every CA NGSS strand so your child can keep up, catch up, or get ahead.

Strands covered: Life Science, Physical Science, and Earth and Space Science
Video lessons taught by certified teachers for every CA NGSS topic
Practice problems and step-by-step explanations after each lesson
Content fully aligned to the California Next Generation Science Standards

CA 3rd Grade Science Topics

Life Science - Students investigate inheritance of traits, variation among organisms, and how animals use their body parts to survive in their environment.
Physical Science - Students explore forces, motion, and the effects of balanced and unbalanced forces on an object's movement.
Earth and Space Science - Students study weather and climate, learning to describe and predict typical weather conditions and how climate varies by region.
Science and Engineering Practices - Students plan investigations, analyze data, and communicate findings as they build scientific reasoning skills across all content areas.

How StudyPug Helps CA 3rd Grade Science Students

When your child gets stuck on a science concept, StudyPug lets them pull up a short video lesson on exactly that topic - whether it is traits and heredity or how forces affect objects. For broader grade 3 science help, the full course is organized so students can move through every CA NGSS strand at their own pace.

Parents looking ahead can also explore the ca grade 4 science curriculum to see what skills come next, or revisit the ca grade 2 science curriculum to fill any gaps from the previous year.

Aligned to CA 3rd Grade Science Curriculum

All StudyPug lessons for 3rd grade science are aligned to the California Next Generation Science Standards (CA NGSS). Every strand - Life Science, Physical Science, and Earth and Space Science - maps directly to what California teachers are expected to cover, so your child is always working on the right material for their grade level.
