Teaching complex subjects like chemistry can be challenging, especially for homeschoolers. However, using hands-on materials can make a significant difference. MIT has created three free science lesson plans incorporating LEGO building blocks to simplify chemistry concepts. Each lesson is designed to take 2-4 hours and is recommended for ages 11 and up.
THREE Free Chemistry Lesson Plans with LEGO
1. LEGO Chemical Reactions Lesson Plan
The LEGO Chemical Reactions lesson introduces students to essential chemistry concepts, such as molecules, atoms, chemical notation, and chemical compounds. Through a hands-on wet lab and LEGO models of atoms, students can visualize and better understand these topics. This lesson plan is a fantastic way to reinforce or introduce chemistry in an engaging way.

2. LEGO Photosynthesis Lesson Plan
In the LEGO Photosynthesis lesson, students construct a glucose molecule by rearranging atoms of carbon dioxide and water. They can then create chains of starch and cellulose, providing a tangible way to grasp the process of photosynthesis. This lesson is ideal for connecting biology and chemistry in a fun and interactive way.

3. Understanding Air with LEGO Lesson Plan
The Understanding Air lesson uses LEGO bricks as atoms to build a model of air. Students then simulate the combustion of fuel models, leading to the production of carbon dioxide and other air pollutants. This hands-on activity helps students understand the composition of air and the effects of combustion on the environment.

Additional Chemistry Teaching Resources
While the LEGO lesson plans are an excellent way to teach chemistry, we’ve found a few more resources to help enhance your teaching experience.
1. Interactive Periodic Table of the Elements
This interactive Periodic Table of the Elements not only provides detailed information about each element but also includes a free printable chart for easy reference. It’s a great tool for students to explore and learn about the elements in-depth.

2. Periodic Table Video Series by the University of Nottingham
For a more visual approach, this Periodic Table video series features explanations of each element by a professor from the University of Nottingham. These videos make the elements more relatable and easier to understand.

Why Hands-On Learning with LEGO Works
Hands-on learning, especially with materials like LEGO, helps students retain information more effectively by engaging multiple senses. By physically building models, students can better visualize abstract concepts, making subjects like chemistry more approachable and enjoyable.
