The Greenhouse Set by United Scientific is an Engino® construction kit that builds a 37 x 35 x 25 cm model greenhouse with gear-operated opening roof flaps. Students control conditions inside and observe how plants respond to temperature, moisture and light, linking biology topics such as photosynthesis with structures and mechanics. The model can be extended with DIY controllers and sensors. It is designed for classroom groups of 2 to 3 students.
