As parents or teachers, you want your kids to learn important things the fun way so they actually imbibe it! Below, take a look at fun science experiments that can be done at the comfort of your own kitchen!
1. Invisible Ink!
For this all you need is lemon juice, heat, paper, a paintbrush, and a total of 25 minutes. The science behind this is that the acidic lemon juice weakens paper, and when you heat the paper the ink is heated and the acid turns brown on the paper.
- Begin, by squeezing a lemon into a bowl.
- Now, paint, the juice onto the paper with a paintbrush.
- Once the paper dries, heat it using a hair dryer or an iron. Ensure that you don’t heat it too long, as it may catch fire.
The brown acid serves as ink and can only be seen once it is heated!
2. How Plants Absorb Water:
This is an extremely cool and fun experiment to do at home. All you need is food coloring, cabbage leaves (white in colour), water, and jars. The food coloring and cabbage leaves to show how plants absorb water (and nutrients) through their stems. You can also perform the experiment with white flowers!
- You will need to add some water to each jar.
- Add a different colored food dye to each jar (8 to 10 drops).
- Add a separate cabbage leaf/flower to each jar.
- Leave your cabbage/flowers overnight to achieve the full effect of this experiment.
Your end result is a bunch of colored cabbage leaves/flowers, which only prove that plants absorb water.
3. DIY Solar Oven:
Are you and your kids craving S’mores? Yes? Then this is the perfect experiment for you. You will need a HOT summer’s day, a cardboard box, aluminium foil, plastic (Ziploc bags will do), black construction paper, tape, pencil, scissors, and S’mores ingredients (chocolates, crackers, and marshmallows). Kids can learn heat sources and the purpose of paper and foil.
- Cut the “Oven Door” flap on the box. The size depends on what you are cooking and how much access you need.
- Place black construction paper in the bottom of the box, as the black colour absorbs heat.
- Cover the inside of the door with aluminium foil. The foil reflects the sun into the oven.
- Add the S’mores!
- Tape the plastic over the opening, creating a seal to keep the heat in.
- Place your oven outside in the sun. I used a pencil to prop the lid open at an ideal angle.
The indicator will be the marshmallow, as they will puff up from the heat.
4. Science On A Stick:
This experiment not only will teach kids science, it also may give them a sugar rush ;). It is all about making edible sugar crystals, or “rock candy,” at home. You’ll need 5 cups of white granulated sugar, 2 cups of water, wooden skewers, and food coloring.
- Moisten one end of the skewer and cover it with granulated white sugar. The sugar should cover around 2-3 inches of the stick. Let the skewer dry.
- Mix two cups water with five cups sugar and set it to boil. The consistency should be syrupy.
- Let the syrup stand until it cools, and pour it into a glass container. Proceed to add the food coloring.
- Set the end of the skewer coated in sugar into the syrup and let it sit for a week.
- Keep moving the sticks around when you have time, so they don’t stick to the bottom.
- Once the candy is ready, drain the excess syrup and enjoy.
