Easy Science Experiments for Primary School Students

Science experiments are the most fun when they are easy, require minimal adult assistance, and can be done without many supplies. Check out the following easy science experiments that may leave you stunned with their outcomes.

What makes a great penny cleaner?

We’ve most often heard taco sauce makes a great cleaning agent for old pennies. Is that true? Let’s find out what makes the bets penny cleaner.

Process

  • Place three coins on three plates.
  • Cover each penny with each of these mixtures: tomato paste + vinegar, salt + vinegar, and tomato paste + salt. Let the mix sit on the coins for five minutes.
  • Rinse the pennies under running water and you can find out who’s the clear winner! Is it the mix of vinegar and salt?

How hard and sturdy are egg shells?

We’ve often observed egg shells cracking even when touched lightly. Conduct this easy science experiment to find out how fragile or hard egg shells really are.

Process

  • Spread a sheet of plastic before doing the experiment because it may turn messy; a couple of eggs are bound to crack!
  • Place two cartons of eggs next to each other. Make sure all the eggs are kept round side up (not the pointy side up) and there are no breaks or fractures in any of the eggshells. Replace the defective ones before you begin the experiment.
  • Remove your socks and shoes. Hold on to a friend and try to step up onto the first carton of eggs with a foot. The trick is to make your foot as flat as possible so that your weight is evenly distributed across the tops of the eggs.
  • When you’ve positioned your foot well, try to shift all your weight on the egg-leg and slowly bring on your other foot on the other carton of eggs. Don’t fret if you hear cracking sounds from the egg cartons. Instead concentrate on balancing on the cartons.
  • So aren’t egg shells stronger than we imagine?

What happens when vinegar and baking soda mix?

Vinegar and baking soda are two commonly used ingredients in the kitchen. What happens when the two are mixed? Let’s find out.

Process

  • Fill up a bottle till half with vinegar.
  • Fold two tablespoons of baking soda in a tissue paper and dump it into the bottle. They key is to put all the baking soda together into the vinegar at a time. You can explore the idea of using a funnel to pour the baking soda too into the vinegar.
  • Stand back and watch what happens! Do you notice an erupting volcano? Baking soda and vinegar, two very easily available ingredients, reacted to form the volcano.

Science Backed Reasons to Get Out and Stay Out

slide_6

I have waxed ad nauseum about all the reasons why PLAY is so essential to your children. I don’t just mean the power of playing games on your phone or playing with Lego. I mean the actual physical act of going outside and letting the wind run through your hair. I know a friend who went to teach English abroad and how she was so shocked to see how the emphasis of education is only on the pure sciences and play time was seen as a waste of time. While play time gives you great life skills, there are a few scientific benefits to it that will make anyone change their mind about going out and playing. Apart from better physical fitness and co-ordination, here is a list of just a few of these great benefits.

Enhanced Resistance to Disease –

This New York Times article has mentioned the evolutionary reasons for kids putting dirt in their mouths or just a natural attraction for soaking their feet in sand. The otherwise “gross” things in the outdoors help improve your immunity.

Better Vision –

This study from the Ohio State University College of Optometry says that 14 hours of natural light every week promotes better vision.

Less Stress –

There have been over a 100 research studies on the role of play in reducing stress and the connection between physical activity and positive psychological responses to them.

More Vitamin D –

While there are food supplements that help you with this, there isn’t enough of this nutrient that can be derived from edibles. 80-90% of our vitamin D source is the sun. No points for guessing what happens if you’re indoors all the time.

Improved Attention Spans –

There are studies done by the University of Illinois Urbana-Champaign that has suggested that even kids with ADHD show reduced symptoms due to outdoor activities. Some studies have shown that your attention span can improve by at least 20% by spending just an hour in nature.

Mathematician of the Month – Pythagoras

PythogorasMr. P was born in a Greek island called Samos and despite the great views; he was more interested in Philosophy and Mathematics. He was also an expert in Astronomy, Religion and Music and wanted nothing more than to share his brilliant ideas with the world. Unfortunately, most people didn’t understand what he was saying and didn’t humor his grand thoughts. Eventually he paid a young boy to listen to him and soon he had created enough interest to start a school and recruit 300 pupils.

He was the most entertaining teacher of the time. He would hide behind a curtain and wait for his class to settle down. He would then jump out and yell the problem at the class and then go back into hiding. After a few minutes, he would jump back out and announce the answer – much to the amusement and confusion of his students.

Pythagoras is known for two major theorems. One is about whole numbers and the other about right angled triangles. They say that he stole the theorem from someone else (even the Egyptians say they knew of the theory) but he was the first one to be able to prove it. To celebrate, he sacrificed 100 cows only to find out that his second theorem disproves the first one. He covered up his mistake but his student leaked the information and was murdered for it.

The secret brotherhood of the Pythogorean School was being viewed suspiciously by the people. It came across as a dodgy sect. When people learnt of the student’s murder, the public rioted and set fire to the school when the members and Mr. P were still locked inside. Despite the horrible way in which he had to go, Pythagoras’s theorem is still being taught at school 2500 odd years later!

Outdoor Science Experiments Perfect for Summer

Rainbows peeping between two baubles of clouds, bright, wild flowers adding a splash of colors to the backyard, slushy strawberry sauces dripping from tall glasses of vanilla ice cream – that pretty much sums up summers! It’s the ideal time to set up science work stations outdoors and experiment with the wonders of summers! Carry out these fun science experiments and amidst the warmth of summer, in your backyard, garden, community park, or elsewhere!

Homemade water sprinkler

Summers are synonymous with cool drinks but it’s not very cool to dispose off the plastics in which the drinks come, so we’ve devised this fun science experiment with the not-so-cool plastic bottles.

You will need:

  • A plastic soda bottle
  • Pins
  • Water

Directions

  • Head out, it’s summer.
  • Fill the plastic bottle with water and screw on the cap.
  • Using a pin, make 5 evenly spaced holes on the side of the bottle, towards the bottom.
  • Run your finger along the streams of water that are gushing from the bottle.
  • Do you notice the five streams forming one wider stream? What forms when you run your fingers through the stream of water is called cohesion. The water molecules get stuck to each other and form one single stream while oozing out from the bottle.

DIY rock candy

How about spending the idle summer holidays doing something that you would not just like to see but eat too! Head out to make a rock candy because it may get messy indoors!

You will need:

  • Cane sugar
  • Drinking water
  • Mason jar
  • Pencil string

Directions

  • Fill the mason jar with water.
  • Add 3 cups of cane sugar to the water and stir well.
  • Place the sugar solution in the microwave and heat on high for two minutes.
  • Use oven gloves to remove the mason jar from the microwave and stir another time.
  • Place it back in the microwave and heat for another two minutes. Remove again and stir.
  • Tie a length of string to a chopstick and gently dip it into the mixture. Pull out the string gently again and allow it to dry.
  • Once dry, dip the string again into the mixture and then allow it a week’s time to dry.
  • Your rock candy will be ready in a week’s time!
  • You created a super saturated solution when you heated the water-sugar solution in the microwave. When you dipped a string into the solution, the sugar granules crystallized and formed a rock candy!

DIY vanilla ice cream

What’s summer without a scoop of our favorite vanilla ice cream? Make ice cream while you’re out running after the butterflies in your backyard and enjoying the summer!

You will need:

  • Two sandwich bags, one bigger than the other
  • A cup of full cream
  • Half a cup of milk
  • A teaspoon of vanilla essence
  • One fourth a cup of sugar
  • 3 cups full of ice cubes
  • 3 cups salt

Directions

  • Mix the cream, milk, vanilla essence, and sugar in the smaller sandwich bag. Seal it well.
  • Slip in the smaller bag into the larger and fill up the larger sandwich bag with the ice cubes and salt.
  • Seal the larger bag (with the smaller bag intact) and head out to enjoy the summers. Just make sure you keep shaking the bags for a good five minutes.
  • Come back in and carefully take out the small bag from the large one and pour its contents in a bowl.
  • Don’t you have a bowl gooey vanilla ice cream in front of you!

Mathematician of the Month – Descartes

Young_Descartes

You know that quote “I think, therefore I am”? Yep, René Descartes said it – our beloved Mathematician of the month. The French philosopher had so many brilliant ideas, he had to stay in bed almost all day just to be able to wrap his mind around them (it might have to do with him being sickly, but we’ll ignore that for now)

His specialty is Geometry – you know, the math of beautiful shapes. One day while he was lying in bed, waiting for breakfast to be brought to him (philosophy seems a great career if you ask me), he observed a fly crawling around the ceiling. When his maid arrived with breakfast, he tried to tell her where the fly had been without pointing it out to her. This obsession led to him chancing upon his greatest idea – grids with axes.

While we give directions in relation to the most recognizable landmark, “along the corridor, second door to your left”, he created grids with numbers. So the fly started at 4,2 which means 4 along the grid and 2 up. The maid rolled her eyes and walked away slowly, refusing to acknowledge the importance of his discover. Within a few years, however, it started being used in Math, Physics and even Geography and is popularly called the Cartesian coordinates.

url Personally, thinking causes me a lot of confusion and so for now, it’s on hold! To be continued …

Before they grow up – Activities to enjoy today!

6-81142-14-1415057748Let’s face it – the parenting journey is chaotic to say the least. There are days when you’re dead on your feet and have to drag yourself in a slow zombie-like stupor. There are days when you have yelling matches with the kids because they want it their own way. There are days that come after long sleepless nights. There are pee stains on the bed, there are food stains all over the couch, there are crayon marks on your favorite purse, there are bald spots from where you have unconsciously pulled your hair out.

6-81134-7-1413244646And then there are days when you laugh so hard you feel like your lungs will burst, there are days when you smile from ear to ear at the sound of their giggle and their tiny footsteps running around the house, days when you wish you were as good a storyteller as they are. When you’re cuddling your little one as they are breathing softly in your arms you realize that you would have it no other way. Let’s face it – parenting is an amazing journey!

I love this phase of my life when the kids are still home and haven’t fled the nest yet. When we mark their heights on the wall, it’s a reminder of how quickly they grow and how deeply our time together needs to be savored. Enjoying your child in the ‘right now’ becomes a priority. Here are some simple things you can do with your little ones that don’t make you feel like you’re missing out on them.

Play their favorite game with them –

I’ve done everything from trying to beat their temple run scores to watching them raise virtual pets and playing MMOs where the whole family has raised dragons together, grown farms, built great architectural wonders, thrown down a block of Jenga bricks and played so many board games, I’ve lost track. There are adventures to be had online and offline. Bonding becomes deeper when you make the effort to be interested in something they love.

Hold hands and go for a walk –

My kids have a timeline of hands where they draw the outline of their own hand every month on a scrapbook and then compare it against the size of my hand. Their thrill at knowing they’re growing up and will soon be as big as mommy is astounding. They then insist on holding my hand and going for a walk, occasionally stopping to see if their hand has gotten any bigger. These memories are now safely stored away in a pensieve! :D

Get lost in a book together –

Speaking of pensieves (and I have play acted Harry Potter to them many times), pick any one of these kids’ books and practice your acting skills. One of my favorite memories of my dad is of him enacting the whole of Oliver’s Twist much to our delight – I can still picture the way he’d take a shirt lying around, turn it into a hat and pretend to be Fagin!

Have a Staring Contest –

Silly, simple, effective – don’t you just love making your kids laugh? Everytime I challenge them to a staring contest, they become serious. The urge to win drives them to play the game like it’s a matter of life and death. I use that as an opportunity to flare my nostrils, wiggle my ears, cross my eyes. As a bonus, go to the bathroom and practice making faces together in the mirror.

Dance, dance, dance –

Before school gets hectic, before they’re off doing their own thing with their friends, use as many opportunities as you can to dance. So what if you have two left feet? The kids love when we blast Macarena from the system and do our silly dance. I enjoy it more when they get to pick a song and they get to teach me their dance moves. The sillier the better!

The Great Outdoors – Activities to transform your backyard!

It’s coming up to my favorite time of year. For those of you who have been reading this blog a while, you know that almost every time of year is my favorite time. I can’t help when each season has its own charm. This season, it is the joy of stepping foot outside of the house and not freezing into a life-sized ice sculpture. Aah the great joys of being outdoors!

I have been making lists, and you know how much I looove lists, of all the activities I could potentially participate in or host this spring/summer. Some of the activities I found online, they blew my mind. Here are some that I’m mostly definitely going to try or con people into trying. What’s great about these activities is that it is something that people of all age can enjoy without having any bones broken or muscles aching.

In no particular order, here are 10 insanely fun games that make you wish summer was a year-long affair.
