Scientific experiments should be able to do with children at home and should not be expensive. Science is a very practical subject and that you have fun with, if you homeschool or not. Scientific experiments are a great way to spend time with your child or children to spend and have fun learning with them. I opted for four experiments, you can simply use the equipment and resources together in most homes.
Experience One: sink or swim
Use a sink or bucket outside when you water, fill with about 5cm prefer empty. Gather common objects like a nail, pencil, raw egg, usually, apple, toy boat, a paperclip and a rubber ball. Make a table with three columns with the headings ITEM, sink, and FLOAT. Predict whether the element to float or sink in a color or a check mark. Place each piece slowly in water and stores it on your table that is really happening (use a different color or crossover). Experiment with different objects and add them to your list – you have the best with your predictions? If you try the experience to investigate a scientific book or website, why are you the results you have to stop to get used to each object.
Experience two: Reflex Grip Fast
Anything you for this experiment is usually (preferably 30cm), a pen and paper and one or more friends.
1) Enter the order with the thumb and index finger at the end with the highest degree.
2) Keep the rule in the head with your arms extended away from the body.
3) Ask to try a friend who usually start with your fingers as you drop the rule.
4) Your friend positions of their thumb and index finger (slightly open) at the lower end of the rule.
5) Press the rule and are preparing to record their results.
6) Note the thumb as friends caught by the rule.
7) Try it with the rest of your friends and record their results.
Now that one of your friends to keep the rule and allow one to go.
Who had the fastest reaction? The person who has the sovereign at the lower end of the reign of the fastest reflexes. What is the sense you use to try to catch the ruler? Tip: Sight
Experiment Three: Volcano
You can use baking soda and vinegar create a chemical reaction using ingenious! You need baking soda (essential to ensure that it is not baking powder), vinegar, a large container and a cloth or paper towel only when you make a big mess! Maybe consider this as an outdoor activity!
Instructions:
1st Put some baking soda in your container.
2nd Pour in some vinegar
3rd Check out the reaction takes place!
What’s going on? Baking soda (sodium bicarbonate) is a database when the vinegar (acetic acid) is an acid. If they react with each other, they carbonic acid, which is very unstable form, it immediately breaks down into water and carbon dioxide, which generates all the glory, as it escapes from the solution.
So why not go one with which a volcano with your technical skills and give a demonstration at a science fair volcano – not to be a little red food coloring to forget really awesome!
Experiment Four: raw or cooked eggs?
As you can tell the difference between an egg is raw and the hard, without breaking them? Answer: This is the force of gravity! For this experiment you need two eggs, a hard-boiled and raw natural. Make sure that the egg was hard not to in the refrigerator long enough to reach the same temperature as the raw egg or experience to function correctly.
Instructions:
1st Turn the eggs and see what happens, an egg should turn, while the other should swinging.
2nd You can also try lightly touching each of the eggs while they are spinning, they should stop quickly, while the others always come after it was hit.
What happened? To move the focus changes in raw egg yolk and egg white as the inside of the pan so that the oscillating motion. Even after touching the shell easy it is to continue to move. It is because of the inertia caused the raw egg to run, even after stopping it. However, makes the hard-boiled egg, rather than flickers and stops when you touch it, because the solid white and yellow.
Older children may be asked to write their experiences in a book by a list of devices, procedures, reporting their findings and then write a discussion to explain what happened.
