From Ecosystems to Atoms: Middle School Science in Action

Fifth-grade students are currently investigating how ecosystems work by building and revising their own food web models. As part of this project, they are exploring what happens when a new species is introduced into an environment and how that change affects the balance of living things.

Through discussion, modeling, and written analysis, students are learning to:

• identify producers, consumers, and top predators

• explain how energy moves through a food web

• predict how changes (such as the loss of predators or plants) impact the entire system

• determine whether a species is native or non-native and how it affects ecosystem stability

This hands-on unit helps students think like environmental scientists as they examine real-world issues such as invasive species, biodiversity, and ecosystem health.

Exploring Atomic Structure – 8th Grade Science

Our 8th-grade students are using interactive PhET simulations to investigate the building blocks of matter. Through these digital models, students are exploring the structure of atoms, including protons, neutrons, and electrons, and how these particles determine an element’s mass and identity.

Students are also examining what makes atoms and molecules stable or unstable and how atomic structure connects to the formation of matter. By manipulating the simulations, they can test ideas, observe patterns, and develop models that explain how atomic composition influences properties.

This work strengthens students’ understanding of matter at the microscopic level while building skills in scientific modeling, data analysis, and using technology as a tool for inquiry.
