Ecosystem Population Dynamics Lab
Students estimate fish by mark-recapture, model deer and lynx–hare cycles, test a kelp web and build energy pyramids.
6 multiplayer classroom games and 1 virtual lab aligned to NGSS standard MS-LS2-3. The games play on one shared screen and the lab runs on each student's device. No student logins, works offline, and every one has a free demo you can try right now.

Students estimate fish by mark-recapture, model deer and lynx–hare cycles, test a kelp web and build energy pyramids.

Producers, consumers, decomposers, food webs and adaptations. Claim the ecosystem four in a row.

The class shouts the letter of the right answer to build a streak before the buzzer. Every right answer makes the clock a little faster.

A science question appears with four answers, one for each corner of the room. Students walk to the corner they think is right, then the answer lights up.

Simon says buzz like a bee if plants need sunlight to grow! Students do the move only when Simon says it and the science is true.

A science statement appears on the screen. Students stand up if it's true and sit down if it's false, then the answer and the real science pop up.

A team review game for every NGSS middle school life science standard. Teams claim tiles on a map by answering questions, and can steal each other's tiles. Play a full review or pick the standards you want. The results show % correct for each standard.
