Greenhouse Design
Students work individually, or with partners, to develop a design for a
greenhouse, and calculate space requirements, equipment needed and cost of operation. They construct a scale model of the greenhouse.

Temperature Variations and Habitability
Students, in groups, evaluate conditions outside the building and inside the classroom using thermometers, barometers, anemometers, etc. They compare interior and exterior conditions. They consider and discuss factors that contribute...
Curated OER
Powers of 10
Students explore universe, and examine how big it really is and how scientists measure the distances or sizes of things by estimating sizes of different objects and reading and writing numbers in scientific notations.
Curated OER
Float or Sink?
Students examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...
