Energy enters and moves through an ecosystem Flow diagram: Sunlight to producers (plants and algae) by photosynthesis, then to consumers by eating, then to decomposers from dead matter. At every step, some energy leaves the system as heat from respiration. Energy flow in an ecosystem Energy enters mainly as sunlight, is transformed, and is lost as heat at each step. Sunlight Producers plants, algae Consumers herbivores Consumers carnivores Decomposers fungi, bacteria detritivores light energy eating eating waste + death heat (respiration) heat heat heat Energy flows one-way: in as sunlight, out as heat. Matter (atoms) can be recycled.

Food Webs & Energy Flow

Lesson Grade 8

A 30 minute Grade 8 lesson on how energy enters ecosystems (mainly sunlight), how producers convert it to chemical energy, and how energy is transferred and lost as heat through a food web.

Why Charlotte Doesn't Freeze in June: Seasons & Earth's Tilt

Lesson Grade 6

Students watch the Generation Genius 'Causes of Seasons' video and build a mental model of how Earth's axial tilt, not its distance from the Sun, drives seasonal changes in temperature, daylight hours, and sunlight intensity across the hemispheres. The lesson connects abstract orbital mechanics to students' lived experience of seasons in Charlotte, North Carolina.

Reading the Rock Record

Lesson Grade 8

Students learn to read Earth's history from rock layers using the Law of Superposition, index fossils for correlation, relative and absolute dating methods including radiometric dating and half-lives, the geologic time scale, and additional geological evidence from ice cores, faults, and igneous intrusions.

Evidence for Evolution

Lesson Grade 8

Students explore four major lines of evidence for biological evolution: the fossil record (including transitional fossils), comparative anatomy (homologous, analogous, and vestigial structures), embryology, and molecular biology (DNA comparisons). Students also learn how modern classification systems reflect evolutionary relationships.
