Make Lemonade Fizzy DrinkThere's a lot of people out there that like drinking fizzy drinks, so why not do a fun science experiment that leaves you with your own lemon soda to drink afterwards!A bit of lemon here and a bit of baking soda there and before you know it you'll be an expert at making your own fizzy drinks. Make your own lemonade softdrink with this fun experiment for kids. | | |
|What you'll need: * Lemon * Drinking glass * Water * 1 teaspoon of baking soda * Some sugar to make it sweet Instructions: 1. Squeeze as much of the juice from the lemon as you can into the glass. 2. Pour in an equal amount of water as lemon juice. 3. Stir in the teaspoon of baking soda. 4. Give the mixture a taste and add in some sugar if you think it needs to be sweeter.What's happening?The mixture you created should go bubbly and taste like a lemonade, soda, fizzy or soft drink, if you added some sugar it might even taste like a lemon flavoured soft drink you've bought at a store. The bubbles that form when you add the baking soda to the lemon mixture are carbon dioxide (CO2), these are the same bubbles you'll find in proper fizzy drinks. Of course they add a fewother flavored sweeteners but it's not much different to what you made. If you are wondering how the carbon dioxide bubbles formed, it was because you created a chemical reaction when you added the lemon (an acid) to the baking soda (a base). |

Make a Tornado in a BottleLearn how to make a tornado in a bottle with this fun science experiment for kids. Using easy to find items such as dishwashing liquid, water, glitter and a bottle you can make your own mini tornado that’s a lot safer than one you might see on the weather channel. Follow the instructions and enjoy the cool water vortex you create! | | |
|
What you'll need: * Water * A clear plastic bottle with a cap (that won't leak) * Glitter * Dish washing liquidInstructions: 1. Fill the plastic bottle withwater until it reaches around three quarters full. 2. Add a few drops of dish washing liquid. 3. Sprinkle in a few pinches of glitter (this will make your tornado easier to see). 4. Put the cap on tightly. 5. Turn the bottle upside down and hold it by the neck. 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 inthe water. You might need to try it a few times before you get it working properly.What's happening?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 foundin nature include tornadoes, hurricanes and waterspouts (a tornado that forms over water). |

Baking Soda & Vinegar VolcanoUse baking soda and vinegar to create an awesome chemical reaction! Watch as it rapidly fizzes over the container and make sure you've got some towels ready to clean up. | | |
|
What you'll need: * Baking Soda (make sure it's not baking powder) * Vinegar* A container to hold everything and avoid a big mess! * Paper towels or a cloth (just in case) Instructions: 1. Place some of the baking soda into your container. 2. Pour in some of the vinegar 3. Watch as the reaction takes place! What's happening?The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonicacid which is very unstable, it instantly breaks apart into water and carbon dioxide, which creates all the fizzing as it escapes the solution.For extra effect you can make a realistic looking volcano. It takes some craft skills but it will make your vinegar and baking soda eruptions will look even more impressive! |
