Students explore what happens to light intensity as depth increases using a light intensity logger. They construct a PVC model to hold water and identify what factors could influence the amount of light attenuation.

Students examine how ice changes state and when  its volume changes.  In this mass lesson students complete a lab that shows them how waters volume can change. 

Students visit science museums. In this hands-on science lesson, students visit the Leith Conservation Trust, Catalyst, and the River and Rowing Museum in person or online to study Britain's waterways.

Students explore the components of a watershed and the factors that affect it. They read a topographical map and use geometry to determine the area of a watershed. Students estimate the volume of a body of water and perform runoff...

Students complete a hands on activity using hard boiled eggs, food coloring, tape, cups, water, and a knife to show how permeability affects animals. In this permeability lesson plan, students complete this activity and learn how...

This presentation begins with the many problems multicellular organisms which rely on diffusion encounter. There are many diagrams of mammalian organ structures, and they are labelled with their relevant functions. This an excellent...

Green roofs aren't just eco-friendly — they are literally green with trees. Groups learn about the concept of green roofs in order to be able to design one. The groups design a 5,000-square-foot green roof for a fictional apartment row...
