[ 01 // THE 45-MINUTE LESSON BLOCK ]

A Complete, High-Engagement Science Block

Designed for standard classroom schedules. Balances pre-lab reasoning, hands-on digital exploration, and rigorous offline synthesis.

[ PHASE 01 // 10 MINS ]
[ OFFLINE PRE-LAB ]

1. Predict & Hypothesize

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.

[ PHASE 02 // 20 MINS ]
[ 3D EXPERIMENTATION ]

2. Run Multi-Variable Trials

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.

[ PHASE 03 // 15 MINS ]
[ CER SYNTHESIS ]

3. Claim, Evidence, Reasoning

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.

[ 02 // CURRICULAR COMPLIANCE ]

Mapped Directly to Next Generation Science Standards

Every level addresses specific disciplinary core ideas, science and engineering practices, and crosscutting concepts.

5-LS2-1

Matter & Energy in Ecosystems

Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment. Students measure biomass conversion ratios between trophic levels.

[ ECOSYSTEM LEVELS 01, 02, 09 ]
MS-LS2-1

Resource Availability & Populations

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.

[ ECOSYSTEM LEVELS 03, 06, 07 ]
MS-LS2-2

Organism Interactions & Predation

Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems. Students analyze predator-prey delayed wave oscillation curves.

[ ECOSYSTEM LEVELS 04, 05, 08 ]
MS-LS2-4

Ecosystem Dynamics & Resilience

Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations. Students test catastrophic tipping points.

[ ECOSYSTEM LEVEL 10 CAPSTONE ]

Trusted by Science Educators & Specialists

Real feedback from teachers who run Praxos dual-format labs in standard 45-minute and 90-minute block periods.

[ 5.0 VERIFIED EDUCATOR ]

"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."

Marcus T.6th Grade Science Lead, Illinois
[ 5.0 VERIFIED EDUCATOR ]

"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."

Rachel K.STEM Coordinator, Ohio Public Schools
[ 5.0 VERIFIED EDUCATOR ]

"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."

Jennifer L.Homeschool Co-Op Director (32 Students), Virginia
