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

Yes. StudyPug covers the life science, physical science, and Earth and space science topics Maine 3rd graders study in class, so your child can find clear explanations and practice right when homework gets tricky.

How long are the video lessons?

Most video lessons run between 5 and 15 minutes, keeping explanations focused and easy to follow. Your child can pause, rewind, and rewatch any lesson as many times as needed to feel confident with the material.

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

Maine does not administer a statewide science assessment at 3rd grade. State science testing typically occurs at later grade levels, so 3rd grade is a great time to build strong foundations without test pressure.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and computers, so your child can access science lessons and practice problems at home, on the go, or anywhere with an internet connection.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can explore the content before committing. Every paid plan also comes with a 30-day money-back guarantee if you decide it is not the right fit.
