Exploring Products: Nano Sand
Source Institutions
In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.
Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
Chromatography
Source Institutions
In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.
Surface Tension Icebreaker
Source Institutions
This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.
Water Wire: Electricity Flowing Through Water
Source Institutions
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.
In the Toilet
Source Institutions
This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.
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.
Foam Tower
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star
Above Water: Buoyancy & Displacement
Source Institutions
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
Draggin' Boats
Source Institutions
Learners design, build, and test models of "dragon boats" made from up to three milk cartons.
Watercraft
Source Institutions
In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.
Design a Submarine
Source Institutions
Learners act as engineers and design mini submarines that move in the water like real submarines.
Filtration Investigation
Source Institutions
In this activity, learners explore how engineering has developed various means to remove impurities from water.
Science at the Waterpark!
Source Institutions
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.
Indicating Electrolysis
Source Institutions
Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.
Mystery Sand
Source Institutions
In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.
Magic Sand: Nanosurfaces
Source Institutions
This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).
Cool It!
Source Institutions
In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!
Exploring Products: Nano Fabrics
Source Institutions
In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.
Marshmallow Models
Source Institutions
No glue is needed for learners of any age to become marshmallow architects or engineers.
