Objective
The experiment explains the Water Cycle, including the terms evaporation, precipitation and condensation.
Material required
- A ziplock plastic bag.
- Color markers (e.g. Sharpie Permanent Markers or any non-erasable markers).
- Blue coloring (optional).
- Packing tape or a nail to hang.
- Draw the water cycle diagram on the ziplock bag including its three stages i.e. evaporation, condensation and precipitation .
- Pour water in the bag.
- Add blue food coloring in the bag and zip it up.
- Hang the bag upright on the window using a packing tape or on a nail in the sunlight.
- After few hours you will see vapors on the bag showing that the water in the bag warmed up and evaporated. As it cooled on rising up, it condensed at the top of the bag in form of clouds.
Human activities like deforestation, and cars and factories burning fossil fuel produce green house gases called Carbon dioxide and Methane. These gases create a barrier in the atmosphere of the earth thus preventing the energy from the sun bounce back. This causes the earth to heat up further. This increased heating of the earth have serious consequences like rising sea level and loss of some species.
Material required
- White paper
- Colored markers and crayons
.
- Cars (you can make or use a toy car)
- Cotton
.
- Glue
- Scissors.
- Take two cardboards and cover them with a white paper. Draw sky on one and land and water on the other. (You can use markers, crayons or paints to indicate these.
)
- Make trees, factory, using the cardboard and decorate it with color markers.
- Stick a cotton pad
in the water to indicate glacier.
- Now label the diagram as shown
in the picture.
- Stick the two pieces of cardboard firmly
vertically.
- Place the car on the surface of the land and your model is ready to demonstrate the process of Global Warming.
- A tub or a deep pan
.
- Rocks
and pebbles.
- Water
.
- Blue coloring
.
- Sea and coastal species (you can use toys for this)
.
- A block of ice
.
- Ruler to measure water level.
- Place a few rocks on one side of the pan and pour some water in the pan
.
- Add blue coloring in the water. This is optional just to make the water look more prominent.
- Place the block of ice in the water area of the pan and drop water species into it.
- Use a ruler to measure the level of water.
- Leave the dish for around an hour and measure the water level again. There is an increase in the level of water which demonstrates how melting of ice owing to the global warming is causing the sea level to rise.
