Sienna Ranch Science is specifically designed for homeschoolers who are looking for a unique opportunity to study age-appropriate science topics based on NGSS standards at our 21 acre Ranch in the hills of Lafayette. We teach the practice and process of science, including hands on experimental methods, lab skills, scientific approaches to problems and an understanding of scientific knowledge to prepare students for their journey into high school and beyond. We always strive to find innovative, fun and effective ways to tie in all of our lessons to life on the Ranch. We might be studying ecology by doing field surveys of biodiversity in the hills, studying gravity and engineering by dropping eggs from the top of the tree fort, or learning about pH in natural ecosystems by testing the water in our pond. Whether their aspirations are highly academic or just scientifically curious, Sienna Ranch Science aims to leave all students with a positive association with science, and to help our students develop into global citizens committed to using their understanding of science to make rational and informed decisions throughout their lives.


Sienna Ranch Science is divided into two classes, 5th/6th grade and 7th/8th grade. Both classes meet at the same time and may spend some time together playing games or completing group activities. Each class has their own separate classroom space and instructor. Both classes complete monthly work samples for students enrolled in charter schools.


Our curriculum is designed so that students can choose to enroll in one session at a time, or in all four years of Science.


Make your day at Sienna Ranch last a little longer! Extensions are 1 hour in duration and precedes Middle School Science. Our staff will guide children from one class to the next in order to ensure a smooth transition. You can register for Extension Classes during the class registration process.
