How Much Water is in that Cloud?
Source Institutions
In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.
Investigating Density Currents
Source Institutions
In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).
Gravity Fountains
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.
Under Pressure
Source Institutions
In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
Penny Drop
Source Institutions
In this quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,
Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
