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

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 Environmental Systems and Societies (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 ecosystems, sustainability, climate systems, water, soils, biogeochemical cycles, natural resources, and human impacts on the environment.

Biology

Resources about cells, genetics, evolution, ecology, and human body systems.

Chemistry

Concepts such as matter, reactions, energy changes, and atomic structure, explained in a student-friendly way.

Physics

Explore phenomena such as motion, forces, electricity, energy, light, and sound.

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.

Digital Resources for Science

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!
