Every time I explained the meaning of each card, I showed videos on you tube to my son to comprehend the context in real situation.
We glued the cards on our weather wall.
Furthermore, we investigated three experiments. The first one was to MAKE A TORNADO using a bottle. The materials we used were: glitter, water, plastic bottle and dish washing liquid.
1st step: Fill the plastic bottle with water until it reaches around three quarters full.
2nd step: Add a few drops of dish washing liquid.
3rd step: Sprinkle in a few pinches of glitter (this will make your tornado easier to see).
4th step: Put the cap on tightly. Turn the bottle upside down and hold it by the neck.
5th step: Quickly spin the bottle in a circular motion for a few seconds, stop and look inside to see if you can see a mini tornado forming in the water. You might need to try it a few times before you get it working properly. This experiment was really nice and easy to make. The glitter spinning inside the bottle made easier to explain to my son the science behind it.
According to Science Kids spinning the bottle in a circular motion creates a water vortex that looks like a mini tornado. The water is rapidly spinning around the center of the vortex due to centripetal force (an inward force directing an object or fluid such as water towards the center of its circular path). Vortexes found in nature include tornadoes, hurricanes and waterspouts (a tornado that forms over water). http://www.sciencekids.co.nz/experiments/makeatornado.html
Our second experiment was to MAKE RAIN, which was easy to make and to explain to your child. All you need is hot water, plate and ice cubes.
1st step: Pour two inches of very hot tap water into the glass container and cover with the plate. Allow water to sit for a few minutes.
2nd step: Place ice cubes on the plate.
3rd step: Watch what happens.
According to Web Weather for Kids the cold plate causes the moisture in the warm air to condense and form water droplets. This is the same thing that happens in the atmosphere as warm, moist air rises and meets colder temperatures high in the atmosphere. Water vapor condenses and forms precipitation that falls to the Earth as rain, sleet, hail, or snow.
The last experiment was to MAKE FOG IN A JAR.
Materials: strip of black construction paper, tape, jar, warm water, food coloring, match and a bag of ice.
1st step: Tape the black paper on the back of the jar, so you can't see through the jar.
2nd step: Fill one third of the jar with the warm water and put a few drops of your preferred food coloring.
3rd step: Light the match and hold it over the jar opening. I suggest you light the match as it is quite dangerous for a child to do. After a few seconds, drop the match into the jar.
4th step: Cover the top of the jar with the bag of ice, and observe the fog forming.
According to Web Weather for Kids the warm water heats the layer of air that it touches. Some of the water evaporates into the air forming water vapor. The warm air containing water vapor rises, and then cools, as it comes in contact with the air cooled by the ice. When the water molecules cool, they slow down and stick together more readily. The particles of smoke act as nuclei for “bunches” of water molecules to collect on. This process is called condensation.
To end our lesson I gave a mini assessment to my son, which he needed to match the words with the pictures.
It was a very productive and fun day indeed :)). Hope you enjoyed my post. Thanks :)).
