In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

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.

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

In this activity, learners build water-propelled engines from soft drink cans.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.
