[ad_1]

science experiments you can perform with the kids at home should not and need not be expensive. Science is a great practical subject and one that you can have a lot of fun whether you homeschool or not. Science experiments are a great way to spend some quality fun with your child or children and have fun learning with them. I have chosen four experiments that you can easily use the equipment and resources commonly found in most homes

Experiment One :. Sink or Float

Using a sink or bucket outside if you want to fill with water, approximately 5 cm empty. Collect some common things instance nail, pencil, raw egg, ruler, apple, toy boat, paper clip and rubber Ball. Draw up a table with three columns with headings team, sink and float. Predict whether the team will sink or float in one color or logo. Place each item slowly in the water and take on board what really happens (using a different color or cross). Try some different things and add them to the list – do you get better with your predictions? When you have completed the experiment to try to use science book or website to explore why you got the results you did for each item

Experiment Two :. Quick Grip Reflex

All you need for this experiment is the ruler (preferably 30 cm), pen and paper, and one or more friends.

1) Remove the ruler with your thumb and index finger on the end with the highest measurement.

2) Hold the ruler at the head level with your arm extended from the body.

3) Ask one of your friends to try to catch the prince with his fingers as you drop ruler.

4) Your Friend position their thumb and pointer finger (slightly open) at the lower end of the ruler.

5) Release the ruler and get ready to take their results.

6) Write down measurement where friends thumb catch ruler.

7) Try this with the rest of your friends and take their results.

8) Now let one of your friends to keep the ruler and let you go.

Who was the quickest response? Whoever catches the ruler at the lowest end of the ruler has the fastest response. What sense are you using to try to reach a ruler? Tip: Sight

Experiment Three: Volcano

may be used baking soda and vinegar to create awesome reactions! You will need some baking soda (important to make sure that it is not baking powder), vinegar, large containers and cloth or some paper towels just in case you make a big mess! Maybe consider this as outside activities

Instructions:

1. Place some baking soda in containers.

2. Pour some vinegar

3. Watch as the reaction takes place!

What is happening? Baking soda (sodium bicarbonate) is static while vinegar (acetic acid) is acid. When they act, they form carbonic acid which is very volatile, it would be a place apart in water and carbon dioxide, which creates all fizzing escaping solution.

Why not have a go at making a volcano with craft skills and give volcano promotion of science fair – do not forget some red food coloring to be very impressive

Experiment Four: Raw or egg

[!?19459002] How do you know the difference between a raw egg and one that is hard boiled without breaking them? Answer: That’s gravity! For this experiment you need two eggs, one hard-boiled and one raw, of course. Make sure that the hard-boiled egg has been in the fridge long enough to be the same temperature and raw eggs or experiment can not function properly

Guidelines :.

1. Revolving egg and watch what happens, one egg should spin while the other should wobble.

2. You can also try lightly touching each of the eggs while they are spinning, one should stop quickly while the other will continue after you’ve touched it.

What happened? Centre raw egg is gravity changes the white and yolk move around inside the shell, causing the wobbling motion. Even after you touch shell light it will continue to move. This is due to the reluctance of causing raw egg to spin even after you have stopped it. In contrast to the hard-boiled egg spins rather than wobbles and stops when you touch it because of solid white and yolk.

Older children can be encouraged to write up their experiments in a notebook with writing equipment list, process, recording the results and then write dialogue to explain what happened.
