Sink or Float?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
Laser Projection Microscope
Source Institutions
In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.
Pop Can "Hero Engine"
Source Institutions
In this activity, learners build water-propelled engines from soft drink cans.
Breaking the Tension: Surface Tension 1
Source Institutions
Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.
What-a-cycle
Source Institutions
In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.
The World's Water
Source Institutions
Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.
Super Soaker
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
Build An Aqueduct
Source Institutions
In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.
Water Motor
Source Institutions
In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.
Stick to It: Adhesion II
Source Institutions
Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.
Stuck on You: Adhesion
Source Institutions
Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.
