Mr. E Science provides science learning resources for students, teachers, and homeschool families. These terms describe permitted use of the free materials owned by Ted Ehrheart/Mr. E Science, unless a particular resource states different terms.
Classroom, homeschool and personal study
You may download and print these free materials for your own study or for students you teach, including use in schools and homeschool groups. You may share copies with those students through a private, access-restricted classroom system, such as Google Classroom. Keep the Mr. E Science name and any credits or copyright notices with the materials.
Sharing with others
Links to Mr. E Science pages are welcome. Please share links instead of uploading copies of our files to a public website, public file collection, or resource marketplace. Please ask for permission before modifying and redistributing materials beyond the uses expressly permitted above.
Resale and ownership
Do not sell, repackage for sale, or claim authorship of our materials without written permission. These permissions do not transfer ownership of the materials. Contact mre@mrescience.com about other uses.
Third-party materials
Some resources, photographs, quotations, videos, and linked materials belong to other creators. Their own licenses and terms apply. Mr. E Science does not grant permission to copy or reuse material it does not own. Use embedded videos through the provided player or their original platform.
Labs and safety
Hands-on activities and dissections require appropriate supervision, equipment, and safety precautions. Teachers and supervising adults must judge each activity's suitability for their students and setting, follow applicable school and supplier instructions, and arrange safe handling and disposal of specimens, tools, and chemicals. Online directions and videos do not replace that supervision.
Accuracy and availability
We work to provide useful, accurate resources, but errors and outdated links may occur. Please report problems to mre@mrescience.com. Resources may be corrected, updated, or removed. Items marked Coming soon are not currently available. Links to outside sites do not place those sites under our control.
Future services
If paid resources or accounts are introduced, their prices, access rules, and applicable terms will be provided separately. These terms do not promise access to features that have not been released.
