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.
Measure the Speed of a Water Leak
Source Institutions
In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.
Floating Paper Clip
Source Institutions
In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.
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.
Sink or Float
Source Institutions
In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.
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
Uplifting Force: Buoyancy & Density
Source Institutions
In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat
Gravity-Defying Water
Source Institutions
In this activity, learners explore gravity and air pressure as they experiment with holding a glass full of water upside down, without spilling it, using a simple piece of cardstock.
School of Fish
Source Institutions
In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.
Draggin' Boats
Source Institutions
Learners design, build, and test models of "dragon boats" made from up to three milk cartons.
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.
Soapy Boat
Source Institutions
Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.
A Spray Spree
Source Institutions
In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.
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.
When is a Glass of Water Really Full?
Source Institutions
In this activity, learners see how many coins they can add to a full glass of water before the water overflows.
Shrinking Cups
Source Institutions
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.
Drops on a Penny
Source Institutions
In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.
Electrostatic Water Attraction
Source Institutions
In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.
