Teaching Science Units with Science Buddies

Discover STEM Lessons for Your K-12 Classroom

What are you teaching this week? Next week? Next month?

Mixtures and solutions? Types of energy? States of matter? Forces of motion? Biodiversity? Newton's laws of motion? Health and human body systems? Magnetism or electromagnetism? Density?

We know educators spend a lot of time searching for quality lessons to fit their curriculum needs each year. Not only do you want quality materials that align with your class objectives, but you want materials that are easy to use, thoughtfully designed and prepared, and help bring concepts to life with hands-on experiments and activities that really work.

Science Buddies offers all of this for free!

Planning for a Year of STEM

No matter what curriculum boxes need to be checked off in the school year, science educators often cycle through a series of important science concepts, principles, and laws.

To make it even easier to find free STEM lessons and activities that fit your teaching needs, we've created a series of Teaching Science Units posts that focus on commonly taught science topics. Each resource in this series offers a curated set of lessons, activities, and experiments that are hand-picked for educators who will be teaching specific subjects.

For other calendar-based STEM connections, see our STEM Calendar for Educators: Month by Month STEM Projects.
