An investigation of Le Chatelier's Principle. Students apply external stresses—concentration and temperature changes—to the Iron(III) thiocyanate equilibrium system to observe, predict, and explain how a system at balance responds to change.

An introduction to reversible reactions and chemical equilibrium. Students use particle models and a pH-sensitive chemical indicator to visualize how reactions can occur in both directions and reach a point where forward and reverse rates are equal.

An immersive hands-on investigation into the physics of sound where students build DIY instruments to explore vibrations, pitch, and volume. This lesson bridges sensory exploration with acoustic engineering principles.

A hands-on exploration of the mealworm life cycle and anatomy designed for early learners to observe and document metamorphosis.

A lesson on the history and importance of conservation in Colorado, culminating in a simulation where students propose solutions to balance recreation and environmental protection.

A lesson focusing on the unique wildlife of the Rocky Mountains, identifying adaptations and ecological roles of various species through a matching activity and creative writing.

A lesson exploring the variety of nature activities in Colorado, focusing on reading comprehension and evidence-based writing. Students will identify supporting details for key main ideas within a complex informational text.

A hands-on exploration of genetics where 5th graders use probability (coin flips) to determine the physical traits of an offspring, demonstrating how heredity leads to biological variation.

A focused practice session on translating chemical reactions between word descriptions and symbolic equations, covering key concepts of reactants, products, and stoichiometry.

A 50-minute introductory lesson on plant and animal cells designed for 9-10th grade self-contained science. Students will explore cell organelles, compare structures, and understand how these 'building blocks of life' function like a factory or city.

In this hands-on lab, students use the floating leaf disk assay to visualize and measure the rate of photosynthesis. They explore how light intensity and CO2 availability act as variables in oxygen production.

An introductory lesson for Pre-K students to explore the materials that make up the Earth's surface: dirt, rocks, and water through sensory observation and sorting.

An introductory lesson on digital printing technologies, covering the mechanics of inkjet, laser, large format, and sublimation printing. Students will learn the pros, cons, and specific use cases for each method.

A comprehensive guide to meiosis, focusing on the structural and functional differences between Meiosis I and Meiosis II through visual identification and comparative analysis.
