5 easy science experiments for kids that will blow your mind

Introduction

Are you looking for few easy science experiments for kids at home ages 3 to 9 and beyond? We all know science experiments for kids and STEM challenges are fantastic for young kids! So what not to choose science activities based on your child’s specific interest? Why not help them experiment on an entirely new topic to expand their learning and teach them about a new area of science? From easy science experiments for kids to the more challenging ones, there are certain amazing science experiments for kids that will help them have fun and learn more about science. We have curated a few experiments for you and your children. These activities below are mainly based on visually stimulating, hands-on, and sensory-rich discovery and exploration! So, keep scrolling this post till the end. 

5 Easy Science Experiments for Kids

1. DNA Model Project.

Building a candy DNA model with kids will allow you to explore and talk about living organisms’ basic biology. Yes, that’s true that DNA is a fairly advanced topic, but there are some simple facts about DNA you can share with your elementary school-age kids. But wait. Wondering what materials to use to make a DNA model? Soft candy that comes in 4 different colours to represent DNA and toothpicks’ structure is an easy way to make your own DNA model. If you have some extra candy lying around or want to pick up a few bags for a group biology project, building a candy DNA model with the kids is a great hands-on science experiment for kids

For that, you would need:

  • Twizzlers 
  • Toothpicks
  • Soft Candy
  • 4 cups to separate candies by color

To perform these fun yet easy science experiments for kids, help them by sorting the four colours of candy into separate bowls and assigning them to a specific nucleotide. These four nucleotides, along with the sugars and phosphates, make up your double helix candy DNA model that is:

  • Adenine
  • Thymine
  • Cytosine
  • Guanine

Now it’s time to start making up pairs for building the candy DNA model. Now make your own unique strand of candy DNA and twist them into what is known as a double helix. The backbone (Twizzlers) of your candy DNA model is what gives the double helix a specific shape. They also hold together the A, T, C, G nucleotides. There are endless combinations that can be made, but the same pairs of nucleotides must stick together.

2. How to Make a Thermometer.

Want to help your kids learn how to make a homemade thermometer? Then this DIY thermometer is one of the most easy science experiments for kids of all ages! 

But before we start, please take a note and make sure that liquid is discarded at the end of this project and all your kiddos know this is not safe to drink. If necessary, make the liquid a “yucky” colour.

At first, you will need:

  • Mason jar with straw lid
  • Clear straw
  • Play Doh or modeling clay
  • Water
  • Rubbing alcohol
  • Cooking oil 
  • Red food coloring

Start by adding red food colouring, 1/4 cup water, 1/4 cup alcohol, and a tablespoon of oil into a mason jar and mix. Then, try to stick the straw through the straw hole and tighten the lid onto the jar. Mould a piece of playdough on the lid around the straw, which will hold the straw about 1/2″ from the bottom of the jar. Hola! Place your DIY thermometer outside in the cold or the fridge and inside the house and look at the difference in how high the liquid rises in the straw at different temperatures.

If your kids ask you, “how did that happen”? Then here is the catch. Many commercial thermometers contain alcohol because alcohol has a low freezing point. As the alcohol temperature increases, it expands and causes the level within the thermometer to rise. The level of the alcohol corresponds to the printed lines/numbers on a thermometer indicating the temperature. And guess what? Our homemade version does a similar thing.

3. Make Cranberry Secret Messages.

Are you a fan of cranberry sauce? If not, it’s okay. But you will be surprised to know that this is one of the best easy science experiments for kids. You can show your kids how they can write and send secret messages to one another! All you need to do is paint with cranberry juice, and the message is revealed. Is it magic or any science? Come, let’s find out!

What you need:

  • Small pot
  • Cranberry juice
  • Whole berry cranberry sauce
  • White paper
  • Baking soda
  • Water
  • Paintbrushes

Add 2 cups cranberry juice and 1/2 can of jellied cranberry sauce to a pot. Bring to a boil over medium/high heat, mixing every few minutes—Mix 1/3 cup hot water with four tablespoons of baking soda. Don’t forget to use the baking soda mixture and a paintbrush to paint a message or picture onto a piece of paper and let it dry. Alternatively, carefully use a hairdryer to dry your messages. Carefully pour the cranberry juice into small coffee mugs and let it cool. And guess what? You can ask your little champ to use the cup of juice as paint and paint the cranberry juice over the dried messages to reveal the secret message.

Any guesses about how our invisible ink works? The cranberry juice and jellied cranberry mixture is acidic and contains a special substance called Anthocyanin. We all know that acids have a pH rating of 4 or lower, but Cranberry juice is around a 2.5 pH rating. The invisible ink we used to write our secret message with the baking soda mixture is a base. It dried clear after being applied to the paper.

Fun and learning Science experiments for kids

4. Rainbow in a Jar.

Easy science experiments for kids involving water is awesome! This water density experiment with sugar uses only a few kitchen ingredients but produces one of the fantastic science activities for class 1. Then what are we waiting for? Let’s check out!

Things we need:

  • 4 Glasses or cups
  • warm water and 1 cup measuring cup
  • sugar and measuring teaspoon
  • food coloring
  • spoon and baster 
  • test tubes

Set out six glasses. Begin by measuring 1 cup of water into each glass. This is a great time to explain the importance of all the glasses having the same amount of water! Add a few drops of food colouring to each glass of water. You can also allow your child to mix the colours! Measure and add a different amount of sugar to each glass of coloured water. We have since cut our experiment down to just four colours, but you can experiment with all of them. Just remember to add: 

  • RED COLOR – 2 TBSP
  • YELLOW COLOR – 4 TBSP
  • GREEN COLOR – 6 TBSP
  • BLUE COLOR – 8 TBSP

Stir until as much of the sugar is dissolved as possible—time to use your baster to create a colourful rainbow in a jar. Squeeze the baster and put it in the red water. Release a little of the pressure to suck up some red water. What next? Keeping it squeezed, transfer to orange, release a little more to suck up some orange water. Continue to do this for all the colours. Make sure you leave enough pressure in the baster to get you through all six colours. Yahoo! Rainbow is formed!

5. How to Make a Solar Oven.

Summer STEM isn’t complete until your kids have made their solar cooker. Did you know the best part of such kind of easy science experiments for kids? You will not need any campfire with this engineering. Isn’t that so classic! From shoeboxes to pizza boxes, you and your kid can just choose anything. These are easy to set up and quick to perform. Most importantly, most activities will take only 15 to 30 minutes to complete and are heaps of fun! Plus, the supplies lists usually contain only free or cheap materials you can source from home!

Things you need:

  • S’mores ingredients (marshmallows, Hershey’s bars, and graham crackers)
  • Cardboard pizza box
  • Black construction paper
  • Aluminum foil
  • Plastic wrap
  • Wooden skewer
  • Hot glue/hot glue gun
  • Scissors
  • Ruler
  • Sharpie

At first, trace your ruler around the box’s top edges to leave an even square and carefully cut out the top. Wrap the cardboard square in foil and glue the edges to secure. Open the box and glue the black construction paper to the bottom of the box. On the inside of the lid, carefully glue a piece of plastic wrap over the opening. Time to make your s’mores! Place four crackers down on the black paper, three chocolate squares, and a marshmallow on top of each one. Carefully close the box’s plastic lid and glue one side of the foil-wrapped cardboard on the top back of the box. Place your DIY solar oven in the sun and wait 60 minutes to watch your marshmallows and chocolate melt.
