Pair browser-based multi-variable simulations with printable Claim-Evidence-Reasoning (CER) student lab notebooks. Zero setup time, 100% NGSS-aligned, and runs smoothly on standard school Chromebook carts.
Designed for standard classroom schedules. Balances pre-lab reasoning, hands-on digital exploration, and rigorous offline synthesis.
Students open their printed lab sheets. Before touching Chromebooks, they analyze initial variable conditions (sunlight, rain, predator densities) and formulate a testable hypothesis with written rationale.
Students open the 3D lab in their browser. They systematically manipulate sliders, trigger ecological stress events (drought, freezes, pack hunting), and record population wave patterns on their daily-tick clock.
Chromebooks close. Students plot trial numbers on the journal coordinate graph, calculate carrying capacity thresholds, and write a formal CER argument defending their conclusions with simulation data.
Every level addresses specific disciplinary core ideas, science and engineering practices, and crosscutting concepts.
Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment. Students measure biomass conversion ratios between trophic levels.
Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations in an ecosystem. Students graph carrying capacity limits.
Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems. Students analyze predator-prey delayed wave oscillation curves.
Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations. Students test catastrophic tipping points.

Real feedback from teachers who run Praxos dual-format labs in standard 45-minute and 90-minute block periods.
"Praxos solved our biggest middle school ecology bottleneck. Setting up physical population labs was always messy and inconsistent. With Praxos, my 6th graders spent 20 minutes testing carrying capacity on their Chromebooks and 20 minutes writing high-quality CER responses on paper."
"The combination of paper predictions and 3D simulation is exactly what NGSS calls for. Students cannot just click randomly because they have to commit to their hypothesis in writing first. It turned our quietest students into confident scientific debaters."
"Zero login friction made all the difference. In a 45-minute period, losing 10 minutes to password resets destroys a lesson. With Praxos, my students clicked the Google Classroom link and were running experiments in ten seconds."
Engineered from the ground up for strict school district compliance, student safety, and universal device accessibility.
Zero student PII required. No student tracking, no profiling, and zero third-party data broker sharing.
Pure distraction-free instructional environment. Zero banner ads, sponsored popups, or gamified loot boxes.
Runs at 60 FPS in Chrome, Edge, Safari, and Firefox. Tested on low-spec school Chromebooks and iPads.
Instant vendor packet fulfillment, formal quotes, and purchase order invoicing for public and private schools.
