200 Free Lesson Plans for Science and Engineering
Plan your school year with ease! Choose from 200+ free science and engineering lesson plans for K-12 teachers!
Science Buddies first started developing NGSS-aligned educator lesson plans in 2017. Our free Lesson Plans help K-12 educators confidently teach science and engineering concepts to students. Today there are more than 200 plug-and-play lessons on our site to support educators teaching science, technology, engineering, and math (STEM).
Lesson Plans at Science Buddies contain scaffolding to help teachers review and prepare to teach a STEM subject, even in an area they may not have taught before. NGSS-alignment information is provided for teachers looking for lessons to meet specific curriculum needs. Lessons also include guided discussion and reflection questions, a step-by-step hands-on activity or experiment, and supplemental materials like worksheets, assessment tools, videos, and more.

In this zoology lesson, students explore the relationship between a habitat and an organism's survival.
In this geology lesson, students make three-dimensional dough models of landforms and bodies of water and explore how they can be represented on a map.
In this physics lesson, students investigate how light bounces off of reflective surfaces and use what they learn to navigate a light maze using a flashlight and mirrors.
In this geology lesson, students learn about the characteristics of different types of bodies of water and make models of lakes, oceans, and rivers inside aluminum pans.
In this human biology and health lesson, students make a model lung from simple materials and explore how lung breathing compares to other ways of breathing.
In this civil engineering lesson, students build model buildings and experiment to see what design changes improve earthquake resistance.
In this materials science lesson, students design and build a controlled-release tablet that releases colored powders at specific intervals.
In this environmental science lesson, students design a mini seeding machine that can plant seeds in a set pattern as they explore the challenge of reforestation.
In this genetics and genomics lesson, students learn about genotypes and phenotypes as they model how traits are passed from parents to offspring.
In this geology and environmental science lesson, students build a model of the water cycle to simulate and observe evaporation, condensation, precipitation, and other water cycle processes in real time.
In this chemistry lesson, students explore how chemical reactions are affected by enzymes and different substrate concentrations.
In this genetics and genomics lesson, students learn about CRISPR technology and create a model and a stop-motion animation video about CRISPR-Cas9.
In this biotechnology and agricultural technology lesson, students learn about prokaryotic and eukaryotic cells and simulate the gene editing process involved in creating a genetically modified organism (GMO).
In this environmental science lesson, students explore the use of mycelium composite as an eco-friendly material.
In this health and human biology lesson, students use SimPandemic, a free online tool, to explore how vaccines affect both individuals and populations during a COVID-19 outbreak.
