The Greenhouse

The glossy catalog is not the same as the data.

The Greenhouse makes your seventh graders the grower, recommending a single plant variety for a large school purchase. Over ten days the catalog with the best marketing keeps tempting them, and the trial data keeps shifting under their feet. The students who update their pick when the evidence changes do real science. It is evidence over spin, day after day.

A worksheet was never going to teach this.

Your seventh graders are not filling in a plant-cycle diagram. They are the grower, choosing one variety to recommend for hundreds of plants, reading the same numbers framed as a winning streak one day and a full season the next. The glossy catalog wants the early call to stick. The growers who follow the data over the packaging, and update when it changes, make the honest recommendation. That is experimental reasoning, with a real purchase on the line.

They are graded on their reasoning, not on which variety they pick.

Here is what surprises teachers. A student who picked the variety the data favors is not graded higher than one who did not. The answer is not the point. Students are assessed on the quality of their reasoning, traced through their own daily journal. A careful recommendation that changed with the evidence scores higher than a lucky guess that never moved. That is how a seventh grader learns the courage to update a position when the facts change.

Let the workbook track the trials.

The Greenhouse comes with a workbook that tracks each variety's growth across the trial as the grower enters the readings. The comparisons build on their own. Their attention stays on the real question, which variety the data actually supports, instead of on keeping the numbers straight.

Every day is already scripted. You just run the room.

You do not need a botany background to teach this. The guide scripts every day, names what students will likely say, and gives you exactly how to respond. The catalog, the sprout data, and the final recommendation are all written for you. You bring the facilitation. The simulation brings everything else.

The lesson plan is already written.

Every simulation comes with a fully editable, admin-ready lesson plan. Standards alignment, daily pacing, learning objectives, differentiation, and an assessment plan are already done, so you can hand it to an administrator or adapt it to your district template in minutes.
