Fun Water Science

Try these simple science experiments in your class. This way children will understand scientific concepts while having fun.

Primary School

A follow up to 'Sink or Float', the activity has children figuring out that shapes can determine whether something sinks or floats.

Sink or Float	Demonstrate that some things float while others sink	Float Boat	A follow up to 'Sink or Float', the activity has children figuring out that shapes can determine whether something sinks or floats
Craft a Raft	A follow up to 'Float Boat', make your class use their imagination and make a ball of clay float	Disappearing Water	Demonstrate evaporation
Straw Experiment

Middle School

How does it become bigger?	Convex lenses explained	Slip Sliding away	A fun experiment on friction. Use this to discuss safety too
Water movements	Show how water can move through cloth by capillary action. Link this up with a drip irrigation model.	Siphon magic	Water pressure and height again. This time it’s an experiment on siphoning liquids
Magic Paper	Use this to explain the concept of air pressure and displacement of air	Measuring Turbidity	Not everyone has access to crystal clear water. Learn about turbidity and measure it using samples of water from different sources
Rain Gauge	Make a rain gauge and use it to monitor rainfall in your school. Calculate the amount of rainwater you can harvest on your rooftop	Rain gauge	Using a plastic throw away water bottle you can make a very simple rain gauge
Rain Water Treatment	Demonstrate a basic rainwater filter in class. If students work on a rainwater harvesting project for the school, they can use this principle and make the filter themselves	Water Contains Oxygen	We can't see it, but it sustains aquatic life. This activity shows that water has dissolved oxygen
Pretty Convection Currents		Bottle Barometer
			When you are discussing barometers, you can show them one from your science lab, or make this barometer in the class
A fountain and a sprinkler	Show how water pressure changes with depth	Fun fountain	Yet another experiment on water pressure and height of a column
Fountain	Check these links to make a sprinkler with an old water bottle. Discuss Newton’s third law of motion after you do this experiment. Instructions for making another fountain	Constant flow bottle	Another experiment to discuss water pressure with respect to height of a column
Make your own aquarium ecosystem		Plant a mini Jungle
Make an Arch		Building Bridges
Make a delta		Water erosion (Block of Sand)
Soil Erosion (Potted Plants)		Make a Water Wheel
Osmosis in colour		Osmosis Potato Experiment
Measuring temperature		Measuring rainfall
Loading Cargo		Hollow hulls

High School

Cohesion - Adhesion	Why does water stick to some materials and not all	Water Temperatures at Different Depths	This activity helps students understand the temperature stratification of water bodies. Combine it with the Presentations on 'Aquatic ecosystems'
Propeller boat	Show them how a propellor works	Surface tension	No tension to demo
Simple tornado	Have a stormy session in class by making these simple tornadoes	Fibre optics	Explain movement of light through a tube and total internal reflection through these simple experiments
Bubbly paths	How does a film of soap travel between fixed points?	Balancing Act	Can you make a pipe balance at a 45 degree angle? Your class on moments of force can be made very interesting. Check this out. . For a one minute film on this click here
Water bottle rocket	Have a science class in the playground. Have the children discuss the hows and whys of rocket propulsion. Why do we need to put some water in the bottle during the experiment?Combine it with the Presentations on 'Aquatic ecosystems'	Inertia Bottles	You can give many examples to explain inertia. Try this experiment and let your class discuss the results
Hydraulic Jack	Science for Std XI and XII can also be fun. Explain basic principles of hydraulics with this simple experiment	Water race	Discuss water pressure with respect to height of a column after you do this simple experiment
Daredevil diver	Teaching Archimedes’ Principle? Try these experiments to explain concepts better	Bubbly bottles	Which principle can you explain using this experiment?
Self Righting Boat		Make a Submarine Float
	Life Boat flip upright automatically		The air will force the water to out of the tanks and you have a floating marine
Make power boat		Chemical Erosion (Sand and Sugar Water)
Testing hull shapes		Testing Upthrust
The WoodenWeather Recorder		Archimedes' Screw
Hydraulic lifter
