Welcome to FIS Year 2!
This project is designed to teach the foundations of science from the ground up through an inquiry-based approach, for free! It is inspired by Bernard Nebel's Building Foundations of Scientific Understanding (BFSU) and the Next Generation Science Standards (NGSS).

I recommend that all learners, regardless of age, begin at the very beginning and work through the lessons at a pace that allows them to understand and retain the concepts. The curriculum is designed to spiral, revisiting ideas while building deeper understanding.

Although the curriculum is organized into Years 1, 2, and 3, those labels are primarily intended for families beginning with young learners. There is also an accelerated schedule that combines the content from Years 1–3 into a single 30-week school year, allowing older students to build a strong scientific foundation without spending multiple years on introductory material.

Because each lesson builds on previous ones, I strongly recommend not skipping lessons. Missing a foundational concept can make later topics much more difficult to understand.

Many of the slideshows are narrated (I'm gradually adding narration to all of them!), but I don't recommend simply putting learners in front of the videos and walking away. This approach works best when it's interactive. Ask questions, encourage discussion, and help learners connect what they're learning to the world around them. For example, after a lesson about energy, point out examples of energy transformations in everyday life. These conversations reinforce learning and help the concepts stick.

I also highly recommend having a copy of Building Foundations of Scientific Understanding (BFSU) alongside this curriculum. While the lessons are designed to stand on their own, BFSU is an incredible resource for parents and educators who want a deeper explanation of the science or ideas for extending learning.

We will open up registration for the fall class by July!
