About Science Practice Lab
Science Practice Lab is a small project focused on one goal: giving students more chances to practice the reasoning behind science, not just its vocabulary.
Why scientific reasoning
Students often memorize the steps of the scientific method without being able to use them. Short, focused practice with real experiment scenarios helps them notice what makes an investigation trustworthy.
Who it is for
Elementary and middle school teachers, homeschooling families, science tutors, and students in grades 5–8 around the world.
Four languages
The site is available in English, Spanish, Brazilian Portuguese, and Indonesian, so students can practice in the language they learn in.
What is available today
You can now practice science online, generate worksheets, view answer keys, and print or save them as PDF using your browser.
