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

Yes. StudyPug covers the topics Ohio 3rd graders work on in class, so your child can find a matching lesson or practice problem whenever they get stuck on homework.

How long are the video lessons?

Most video lessons are short and focused, typically just a few minutes each, so your child can watch one concept at a time and move on to practice without losing focus.

Is there a state science test for 3rd grade in Ohio?

Ohio's primary science assessments are given at grades 5 and 8, not grade 3. StudyPug still helps build the foundational knowledge that those later assessments will draw on.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and computers, so your child can watch lessons and complete practice problems at home, at school, or on the go.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can see how it works before subscribing. There is also a 30-day money-back guarantee if it is not the right fit.

Ohio 3rd Grade Science Topics

Forces and Interactions: Students examine pushes, pulls, and how forces change the motion of objects.
Life Cycles: Students compare the life cycles of plants and animals and explore how traits are passed from parents to offspring.
Ecosystems: Students investigate how living things depend on each other and on their environment for survival.
Weather and Climate: Students observe and record weather patterns and learn how climate differs across regions.
Earth's Materials: Students study rocks, soil, and fossils as evidence of past environments and Earth processes.
