Microbiology: The Hands-On Science Series

Microbiology: A Hands-On Course is a 12-chapter, interdisciplinary science curriculum designed for students in grades 4–7. Developed by Blair Lee and published by SEA Publishing, the course offers an immersive introduction to the microbial world, covering bacteria, viruses, fungi, algae, and protozoa. Each chapter blends engaging narrative science writing, vibrant illustrations, embedded instructional videos, and thoughtfully designed labs that foster critical thinking and scientific literacy. With integrated topics in genetics, immunology, epidemiology, synthetic biology, and environmental science, the course also incorporates writing, math, and creative expression to support a comprehensive and inquiry-based science education.

This course is rooted in an inquiry-based, interdisciplinary approach that invites students to engage with microbiology as both scientists and communicators. Lessons are designed to activate curiosity, introduce rigorous scientific content in accessible language, and provide multiple entry points for comprehension through visual, auditory, and kinesthetic learning. Hands-on labs and modeling tasks encourage application and synthesis, while writing and math prompts foster interdisciplinary thinking. Embedded videos support visual learners, and integrated art and design challenges allow for creative interpretation of scientific ideas. Grounded in Next Generation Science Standards (NGSS) and Common Core literacy practices, the curriculum is academically rigorous yet flexible, offering families and co-ops a rich, secular science program that supports depth over breadth.

Mission

SEA Homeschoolers has a large, active, and diverse online community of secular homeschooling families from around the world. We are constantly growing and evolving. We provide support and vetted secular homeschool resources, including secular homeschool curriculum, in various ways, both online and at in-person conferences. SEA Homeschoolers is passionate about providing innovative education through secular academic materials and celebrating the secular homeschool community by connecting with the people creating these resources and the families and educators who are handcrafting their student’s journey through learning.

Story

SEA was founded by Blair Lee. When her son was 5 years old, she wanted to create a handcrafted education that would support his unique strengths. She found many compelling arguments about the importance of customizing education, but had a hard time finding resources to help her make that happen! SEA was created to help homeschoolers find resources to create an innovative and academically rich curriculum. SEA came out of the need for a community that focused on innovative, secular, and academic homeschooling. The SEA community was really important to Lee when she was handcrafting her son’s education. Community allows you to benefit from brainstorming, mentoring, and insight into the how. The team at SEA continues to foster this community so that families around the world can benefit from it!

FAQ: Additional Details about Microbiology: The Hands-On Science Series

Each lesson begins with a clearly written chapter that introduces a central microbiology concept—such as bacterial reproduction, genetic mutation, or immune response—through age-appropriate scientific language and detailed visual support. Students then engage with one or more embedded instructional videos that reinforce key ideas, followed by short-answer questions and modeling prompts to check comprehension. The lesson culminates in a hands-on lab activity, such as culturing bacteria, simulating viral transmission, or building a model cell. Students are also encouraged to complete reflection questions and explore optional extensions, which may include research, art, or design challenges.

The course is delivered as a digital e-book, with embedded video content accessible directly within the text. A downloadable PDF appendix provides all necessary supplemental materials, including lab instructions, vocabulary lists, problem sets, graphic organizers, answer keys, and a full materials list. Lessons are designed to be completed sequentially over 12–15 weeks, with each chapter containing integrated reading, video, experimentation, and writing components. Students progress through five units, moving from foundational biological principles into bacteria, viruses, historical pandemics, and eukaryotic microbes.

This course is best suited for students in grades 4–7 who are eager to explore life sciences through a blend of reading, experimentation, and creative inquiry. It is particularly well-aligned with learners who enjoy connecting scientific concepts to real-world applications and are capable of independent or guided reading and writing. Homeschoolers and co-op students who benefit from cross-curricular integration and scaffolded critical thinking will find this curriculum both challenging and rewarding.

Microbiology: A Hands-On Course may not be appropriate for students who require extensive support with reading comprehension or writing, or for those significantly below grade-level expectations in literacy. Families seeking a lab-only curriculum or a classical textbook-style program without multimedia elements may prefer a more traditional resource. The course also assumes a basic level of scientific curiosity and willingness to reflect, model, and write—traits that may not align with highly reluctant learners or those who struggle with open-ended tasks.

Microbiology: A Hands-On Course can be a strong fit for students with ADHD and other learning differences, thanks to its project-based, multisensory design. The course blends short readings with embedded videos, visual modeling, and hands-on labs, offering multiple modes of engagement that help sustain attention and promote active learning. Its flexible pacing and open-ended extensions allow families to adapt the material to each learner’s needs, and the emphasis on doing—rather than passive consumption—makes it particularly effective for students who struggle with traditional lecture or worksheet-based formats. While the course may require support with reading or writing for some learners, its dynamic structure and real-world connections provide a meaningful and accessible entry point into life science.

While the course is designed to foster independent learning, caregiver involvement is essential—particularly in guiding younger students through reading, facilitating experiments, and supporting writing or modeling activities. Parents are encouraged to help set the pace of the course, organize lab materials, and lead post-lab discussions. Over time, students can take greater ownership of their learning, but consistent adult engagement ensures both safety and deeper comprehension, especially in the earlier chapters.
