Science can be fun for all age groups. Not only does it communicate the meaning of a lot of questions we ask on a daily basis but it also clarifies notions we’ve had till now.
How about combining knowledge with thrill and making the entire experience enjoyable. Simple experiments at home with minimum readiness can create a lot of understanding.
We list down two hands-on activities that help bring the exciting world of science to life – experiments that kids can easily do at home. Under adult supervision of course.
Make an Egg Float in Salt Water
An egg sinks to the bottom if you drop it into a glass of ordinary drinking water but what happens if you add salt? Let’s watch out.
What you’ll need:
- One egg
- A tall drinking glass
- Pour water into the glass until it is about half full.
- Stir in lots of salt (about 6 tablespoons).
- Carefully pour in plain water until the glass is nearly full (be careful to not disturb or mix the salty water with the plain water).
- Gently lower the egg into the water and watch what happens.
Salt water is denser than ordinary tap water, the denser the liquid the easier it is for an object to float in it. When you lower the egg into the liquid it drops through the normal tap water until it reaches the salty water, at this point the water is dense enough for the egg to float. If you were careful when you added the tap water to the salt water, they will not have mixed, enabling the egg to amazingly float in the middle of the glass.
Another interesting experience to create the perfect hues and colours right in your own house.
Make your own rainbow –
Learn how to make a rainbow with this fun science experiment for kids. Using just a few simple everyday items you can find out how rainbows work while enjoying an interactive, hands on activity that’s perfect for kids.
What you’ll need:
- A glass of water (about three quarters full)
- White paper
- A sunny day
- Take the glass of water and paper to a part of the room with sunlight (near a window is good).
- Hold the glass of water (being careful not to spill it) above the paper and watch as sunlight passes through the glass of water, refracts (bends) and forms a rainbow of colours on your sheet of paper.
- Try holding the glass of water at different heights and angles to see if it has a different effect.
While you normally see a rainbow as an arc of colour in the sky, they can also form in other situations. You may have seen a rainbow in a water fountain or in the midst of a waterfall.
Rainbows form in the sky when sunlight refracts (bends) as it passes through raindrops, it acts in the same way when it passes through your glass of water. The sunlight refracts, separating it into the colours red, orange, yellow, green, blue, indigo and violet.
So get set go……its experiment time!
