Welcome to Mr. Kremer Science, a collection of free, classroom-ready science resources designed for middle school and high school students.
This site supports biology, environmental science, chemistry, and Earth systems with clear explanations, visual models, and curriculum-aligned materials.
Whether you’re a student reviewing key concepts or a teacher planning lessons, you’ll find organized, standards-based science content built for understanding — not memorization.
Check out my YouTube channel! I make science videos that support the resources on these pages.
Explore Science Topics and Resources
Each section below focuses on core science topics taught in middle school and high school. Many resources are aligned with the IB Diploma Program and IB Middle Years Program. Resources include diagrams, videos, presentations, summaries, guiding questions, and review materials to support learning at different levels.
IB ESS
Resources for teaching and learning about the new ESS syllabus at both standard level (SL) and higher level (HL), with first examinations scheduled for 2026. Topics include perspectives, ecosystems, sustainability, climate systems, water, soils, biogeochemical cycles, natural resources, and human impacts on the environment.
MYP Astronomy
Learn about the Big Bang, planetary systems, eclipses, astrobiology, and deep space phenomena.
MYP Biology
Resources about cells, classification, plant biology, anatomy and physiology, reproduction, genetics, inheritance, and evolution.
MYP Chemistry
Concepts such as measurements, atomic structure, periodicity, bonding and chemical reactions, and stoichiometry, explained in a student-friendly way.
MYP Physics
Explore phenomena such as motion, forces, electricity, work, energy, light, optics, sound, and radioactivity.
Built for Students and Teachers
All content on this site is designed to be:
- Clear and concept-focused
- Aligned with common secondary science curricula (IB DP, IB MYP, AP, NGSS)
- Easy to use in classrooms or for independent study
- Free and accessible without sign-ups
Teachers can use these materials to support instruction, while students can use them for review, exam prep, or deeper
You’ll find resources I think are valuable for students. There is guidance on writing science lab reports, creating data tables and graphs, and developing effective presentations for science. You’ll also find a list of digital science resources I’ve been using for many years.
Why Concept-Based Science Matters
Science learning is strongest when students understand how systems work, not just isolated facts. These resources emphasize:
- Systems thinking
- Real-world examples
- Visual models
- Connections between topics
This approach supports long-term understanding and success in advanced science courses.
Start Exploring
Browse the topic sections above. Explore resources in environmental science, biology, chemistry, physics, and Earth systems. These resources are designed to support learning, curiosity, and scientific thinking.
I’ve also curated a set of books and other resources to help you either teach or learn about science (or both). You can find my recommended reading here.
Science Resources
I began curating this list of science resources years ago. I save and bookmark sites, videos, simulators, and news articles about the environment and sustainability almost daily. However, there’s just no way to keep up with it all. That means several URLs are probably broken by now. The volume of new resources geared toward science education is simply overwhelming.
How to write MYP science reports
I’ve used checklists. I’ve created formative tasks focused on one assessment strand at a time. I’ve made templates with clear headings and explanatory paragraphs. I’ve also designed heavily scaffolded worksheets for English Language Learners. In the end, most of my students rely on this visual explanation of how to write MYP science lab reports. So here it is.
How to Create Scientific Tables and Graphs
Visual models and exemplars are often the easiest and most effective ways to show students how to produce something.
How to Effectively Communicate Scientific Knowledge
I’ve shared this presentation with students for years. I think it’s the clearest, most concise guide to visual presentations I’ve ever encountered. Death to ‘death by PowerPoint!’
Happy learning!
