Science Experiments you Can Try With Home Supplies!
Let’s Indulge in Science Experiments
Around the world, millions of kids are headed back to school in a totally different way. Classes are online. Teachers talk to students in virtual classrooms. And parents are often left looking for new, hands-on science learning opportunities to help their children understand the theory in a practical way.
We’ve got your back. Here are six fun and easy science experiments that you can do at home with kids of all ages!
6 Science Experiments Safe to Perform at Home
Making a cloud in a jar
What you’ll need: a one gallon size glass jar, matches, a rubber glove, a rubber band, flashlight or lamp, food coloring, and water.
Experiment: Pour boiling water into the jar – just enough water to cover the bottom of it. Swirl the water around inside so that it covers the sides of the jar. Put the rubber glove wrist around the mouth of the jar with the fingers pointing downward and put your hand in the glove. Once your hand is in the glove, move it upward so that you pull the fingers of the glove up. You’ll notice that nothing happens to the water. Take the glove off the jar for just a moment, light a match and drop it in the jar. Stretch the glove back over the jar, with the fingers pointing down.
The water at the bottom of the jar will put out the match, and smoke will form inside the jar. Slide your hand into the glove and pull it outward again.This time, a cloud will form in the jar. When you put your hand back inside the glove, the cloud will disappear. This will last for 5-10 minutes. When you shine a flashlight at the jar, you can see the clouds better.
How it works: The air is full of warm water vapor molecules inside the jar. The glove compresses the air because the glove takes up some of the space inside the jar. Pulling the glove fingers out of the jar releases some space in the jar and the air cools.The smoke from the match acts as a vehicle to which the water molecules can attach. They stick to the smoke particles, condensing into cloud droplets. If you want colored clouds, add a few drops of food coloring to the water in the bottom of the jar before adding the match.
What you’ll need: A container filled with water (such as a bathtub or a washbowl), a flashlight, a mirror, and a sheet of white paper.
Experiment: Fill the container with water and place the mirror at the bottom of the container. Aim the beam of light of the flashlight at the mirror. Make sure that it reflects off the surface of the mirror onto the sheet of paper. If done correctly, a rainbow should appear on the paper.
How it works: As it passes through water, a beam of light splits into its 7 component colours. As a result, a rainbow appears in these science experiments!
Volcano science experiments
What you’ll need: A tray, a small plastic bottle, sand, food colouring, baking soda, vinegar.
Experiment: Use clay and sand to mould a volcano shape around the small plastic bottle – to add ambience to the experiment. To make it erupt, pour two tablespoons of baking soda into the bottle, then add a quarter of a glass of warm water. Put in some food colouring. Finally, add a quarter of a glass of vinegar.
How it works: These science experiments show that when soda comes into contact with vinegar, a violent reaction occurs, causing an emission of water, salt and carbon dioxide (CO2 bubbles being the force that drives the contents of the ”volcano” upwards).
What you’ll need: Salt, water, a piece of wire.
Experiment: To grow crystals, you need to prepare a supersaturated salt solution. The concentration of salt should be such that, if you add any more, it won’t dissolve. Make sure that the solution remains warm. To make the process run more smoothly, you’d better use distilled water. When the solution is ready, pour it into a new container – to get rid of dirt traces that are always present in salt.
Now you can take a piece of wire, make a small loop at one end, and lower it into the solution. Put the container in a warm place, so that the liquid won’t cool down right away. After a few days, beautiful salt crystals should grow on the wire. If you get the hang of it, you can grow quite large crystals and even make patterned handicraft by twisting the wire into various shapes.
How it works: As water cools down, the solubility of salt decreases. This leads to precipitation, with salt crystals forming on the container walls and on the wire.
What you’ll need: A bottle, a coin large enough to cover the bottle’s mouth, and water.
Experiment: Place the empty uncapped bottle in the freezer. Keep it there for a few minutes. Take the coin and dip it in water. Remove the bottle from the freezer and put the coin on top of the bottle, so that it covers the bottle’s mouth. After a few seconds, the coin should start jumping on the bottle’s rim, accompanied by curious clicking noises.
How it works: Hot air takes up more space than cold air. When you take the bottle out of the freezer, the air inside the bottle begins to warm up and expand. It rushes out through the bottle’s mouth, making the coin ”dance” in these science experiments.
Multi-coloured milk science experiments
What you’ll need: Whole milk, food colourings, liquid detergent, cotton swabs, a plate.
Experiment: Pour some milk onto a plate. Add a few drops of food colouring. Take a cotton swab; dip one end of it into liquid detergent. Next, press the detergent-covered swab to the centre of the plate. The milk will begin to swirl, forming colourful patterns.
How it works: The detergent reacts with the milk’s fat molecules, setting them in motion. That’s the reason why using fat-free milk for the experiment just won’t do!
Science helps children develop key life skills, including an ability to communicate, remain organized and focused and even form their own opinions based on observation. Science experiments also help children develop their senses and overall awareness. It also shows us how to get great at solving problems. With these science experiments your child can learn more about science and be interested in the science subject. Also your child can indulge in toys and educational kits and explore the fundamentals of science!
