Capillarity – Measuring Surface Tension
How do cohesion and adhesion work together? The third installment of a nine-part series teaches young scientists the difference between adhesion and cohesion. They also learn how cohesion and adhesion work together to cause capillary...

Soil Water Worksheet #1
Drawings of four groups of soil particles of varying sizes are displayed across the page for soil scientists to examine. As they complete the worksheet, place a set of similar soils at each table for hands-on experience. In this way,...
Curated OER
Peat Pots
Students place a peat pot in water to observe and calculate the rate of capillarity in a model of a soil. This task assesses students' abilities to make simple observations, collect, record, and represent data, use a data table to...

Water and Climate
Dive into a lesson on the hydrosphere with this Powerpoint presentation. Building on prior knowledge of the water cycle, young scientists learn what happens to water after it falls as precipitation and explore the different factors...
Biology Junction
Water, Solutions, pH, and Buffers
What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

Support and Transport in Plants
All types of transport systems in a dicotyledon plant are detailed here, with clear labelled diagrams and notes for the specific structures and functions. The way that these systems have adapted, and how support is assisted by the...
Curated OER
Does Size Matter?
Young scholars explore the surface area to volume ratio in cellular respiration. While participating in an interactive lab experiment, they examine proportional surface area and discuss nanotechnology. Students observe the...
Curated OER
Survival Still
Students explain how to desalinate water using solar energy. In this solar instructional activity students complete a lab activity and explain capillary water.
