Kids Science Experiments.
Science is full of fascinating hands on experiments which are a great way to enjoy science and learn.It teaches the kids interesting,science and technology facts by experimenting with different materials that have different out comes.I am going to give you some experiments that uses materials from around the house that are safe and perfect for kids.
Use baking soda and vinegar to make an awesome chemical reaction.Watch as it rapidly bubbles and spills over your container.I suggest doing this outside on the driveway can make a mess.
What you will need:
.Paper towels to clean up mess
1.Place some baking soda in the container.
2.Pour in some vinegar
3.Watch the action happen.
The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonic acid which is very unstable, it instantly breaks apart into water and carbon dioxide, which creates all the fizzing as it escapes the solution.
Diet coke and Mentos candy
This is another easy fun experiment to do but best done outside as it make a mess.This experiment does work better with diet coke then regular soda due to slightly different ingredients in the sodas.
Things you need:
.Large bottle of diet coke
.Half a pack of mentos away from the house and we can wash it down with the hose.
1.Make sure you are in an area where you wont get diet coke every where and get in trouble. We do it on the sidewalk away from the house and an area where we hose it down with water.
2.Stand the Diet Coke upright and unscrew the lid. Put some sort of funnel or tube on top of it so you can drop the Mentos in at the same time (about half the pack is a good amount). Doing this part can be tricky if you don't have a specially designed geyser tube.
3.Time for the fun part, drop the Mentos into the Diet Coke and run like mad! If you've done it properly a huge geyser of Diet Coke should come flying out of the bottle, it's a very impressive sight. The record is about 9 meters (29 feet) high!
When the mentos come in contact with the coke,a rapid reaction will start and form a foam.The foam is made by the CO2 in the coke, gelatin and gum arabic ingredients in the mentos.It is important that they are mint mentos and not fruit mentos.
Dancing raisins is a fun experiment for the little kids it is safe and stress free from chemicals.
What you need:
1 can of 7up/sprite
Small box of raisin (snack size is good)
Take your glass and pour 7up in to the glass notice the bubbles raising up from the bottom which is carbon dioxide.Drop raisins in the glass a few at a time.Bubbles will stick to the raisins and make the raisins grow bigger.The bubbles float and eventually overcome the raisin's weight, and it floats upwards.Eventually the bubbles make the raisin float and it moves upwards to the surface, where some of the bubbles pop and the raisin sinks again.
You spill water and you grab a paper towel and the water disappears that is called absorption.The paper towel is absorbing the water.
What you need:
1.Clear plastic containers
3.Paper towels (the thicker the better)
Fill one cup with water and stir in some food coloring,any color you like.Roll up a paper towel and place one end in the cup of water and the other end in an empty cup besides it.Watch as the the colored water travels from one end of the paper towel to the other end.Eventually both cups will have the same amount of colored water.Want to take it to another level? okay know fill two cups with the same amount of water and add blue dye to one and yellow to another.Place and empty cup between the colored water.Roll 2 paper towels up,place the end of one paper towel in the blue cup and the other end in the empty cup then place the other towel the same way in the yellow dye.Know watch the magic happen.The middle cup should have green colored water in it.You can use other colors to make different colors and this is a great way to teach kids how to mix colors to make another color.
How about an experiment where you can eat the results? i have got one and so delicious.Making your own rock candy is a fun and tasty way to grow crystals and see the structure of sugar and a bigger scale.
What you need:
1.3 cups sugar
2.1 cup water.
3.Clean glass jar
6.1/2 tsp of extract (flavor of choice)
1.Pour the sugar and water in to the pan and bring to a boil stirring constantly .you do not want to overcook as it will turn hard and that is not what you want to happen.you want the sugar to dissolve.
2.Add the food coloring and the choice of extract if you chose to flavor it.
3.Set the solution to the side to cool to about 50 degrees. Put the stick into the clothespin so it hangs down in side a glass.
4.Might want to have an adult help you with this next stage.pour the sugar solution into the jar almost to the top. Then submerge the skewer back into the glass making sure that it is hanging straight down the middle without touching the sides.
5.Set your jar a side and do not disturb it.Ideally let it grow 3-7 days.Once the candy is the size you want,remove it and let it dry.Know eat and enjoy.
This is a great little experiment for the little kids my 3 year old daughter loves it especially the glitter effect.
What you need:
4.Food coloring (we used Red)
5.Glitter (we used a dark blue)
1.place 3 tablespoons of baking soda in to the glass jar.Place the glass jar in to the pan.
2.Add 7 drops of food coloring.
3.Add about 2 teaspoons of glitter.
4. Quickly pour the vinegar in the jar and watch the magic happen.
Baking soda and vinegar react against each other and cause an eruption.Baking soda has a base and the vinegar has an acid so mixing a base with acid causes the eruption.
Make a balloon rocket and have fun.This is a fun experiment using a balloon which fly's through the air.
What you need:
2.Long piece of string
1.Tie one end of the string to a chair,doorknob or something that will support the string
2.Put the straw through the other end of the string and pull the string tight and tie it to another support.
3.Blow up a balloon (but don't tie it) pinch the end of the balloon and tape it to the straw.
4.You are ready for take of.Let go of the balloon and watch the rocket fly.
The air rushes out of the balloon and creates a forward movement which creates a thrust.The flight altitude mounts to some meters. The balloon can also be filled with gases other than air, with similar results.
