Does Science Notes and Projects Offer Free Worksheets for Biology and Math?

Updated

Yes. Science Notes and Projects publishes free biology worksheets and printables for K-12 and college, plus math worksheets covering algebra, geometry, trigonometry, arithmetic, and more. The site also offers printable trigonometry reference sheets and chemistry charts and tables as PDF files. The material is presented as free educational content; no pricing or login requirement is mentioned in the site's own description.

Biology Worksheets and Printables

The site states that it provides biology worksheets and printables for K-12 and college levels. This makes it a reasonable starting point if you need practice material or classroom handouts across a wide range of grade levels rather than a single course.

Because the description groups K-12 and college together, expect the collection to span introductory life-science topics through more advanced material. Check the individual worksheet pages for the specific topic and level before assigning or printing.

Math Worksheets

Math worksheets are available in several subject areas:

  • Algebra
  • Geometry
  • Trigonometry
  • Arithmetic
  • Additional math topics

The site notes that its authors both hold degrees in math, and it invites requests for trigonometry or statistics content. That means the math section is actively maintained rather than a fixed archive.

Trigonometry Reference Sheets

Beyond practice worksheets, the site offers printable trigonometry references:

  • Right triangles
  • Trigonometry functions
  • Special triangles
  • Trig tables — SIN, COS, and TAN values
  • PDF trig identities study sheet

These are reference sheets rather than problem sets, so they pair well with the worksheets when you need both formulas and practice.

Chemistry Charts and Tables

If your needs extend past biology and math, the site also provides essential chemistry references as PDF files:

  • Alphabetical list of the chemical elements
  • Periodic table trends
  • Valences of the elements
  • Electron configurations of the elements

These are downloadable and printable at your convenience.

How to Get and Use the Materials

The worksheets and reference sheets are accessed directly through the site's pages. The chemistry tables are described as PDF files you can save and print whenever you need them. The periodic tables are available as both PDF and PNG.

A practical workflow:

  1. Identify the subject and level you need (for example, high school algebra or college biology).
  2. Open the matching worksheet or reference page.
  3. Download the PDF or PNG where offered.
  4. Print or save for offline use.

What to Keep in Mind

  • The site describes its content as free, but it does not state terms of use for classroom redistribution — check before sharing widely.
  • Coverage is broad (K-12 through college), so verify the difficulty level of a specific worksheet before using it.
  • Reference sheets and worksheets serve different purposes; use the trig identities and tables alongside the practice problems rather than instead of them.
