Practical knowledge is at least as valuable as theoretical knowledge is. Experiences at any age add different information to people. The fact that children experience the theoretical knowledge they learned at school with experimental methods at home increases the retention of knowledge. In this article, we have compiled 7 experiments that can be done easily and with little material at home.
- Fireproof Balloon Experiment
Purpose of the experiment: How to make the balloon resistant to flame.
Materials: Candle, match or lighter, balloon
Preparation: Fill the balloon with half a glass of water and inflate the balloon and tie it tightly. Then light the candle with a match or lighter and grab the balloon from the top and bring the portion with water closer to the candle. Yeah, the bubble doesn’t pop, but how did this work?
- Colorful Cabbages
Purpose of the Experiment: Understanding the effect of capillaries in some plants.
Materials : 4 colors of food coloring, 4 glasses of water and 4 cabbage leaves.
How to make: Let’s pour different colors of food coloring into each glass filled with water, then place the cabbage in the glass with the leaf parts out. Keep it that way for one night. You will see that the color of the leaves has changed in the morning.
- Floating Egg
Purpose of the Experiment: Understanding the density of the molecules that make up the water and the egg.
Materials: 2 eggs, 2 glasses of water and salt.
Preparation: Place one egg in a glass of water. The egg must fall to the glass. Put hot water and 4 spoons of salt in the second glass and let the water cool. Then put one egg in his second glass. The egg will rise above the water..
- Magic Balloons
Purpose of the Experiment: Understanding the effect of carbon dioxide gas, produced by the reaction of vinegar and baking soda.
Ingredients: 3 plastic water bottles, 3 balloons, funnel, liquid food colorant, vinegar, 3 tablespoons baking powder.
Preparation: Let’s pour a spoonful of baking soda into each bottle using funnel, put 5 tbsp of vinegar in each bottle and add a few drops of food coloring. Let’s put the balloons into the bottles and then remove the bottles so that baking powder and vinegar mix. When baking soda and vinegar react, the carbon dioxide that emerges cannot find enough space in the bottle and comes out, and the outflowing gas balloons inflate.
- Poor Match
Purpose of the Experiment: Understanding the shadow caused by the inhibition of light.
Materials: Some matches and a lantern.
Preparation: Put a flashlight on your head. Then light a match and keep it a little away from the wall. You will only see your hand and the shadow of the match on the wall. The shadow of the flame will not be visible because it cannot have the shadow of the flame. Their shadows are formed because they prevent the light coming on physical substances, but the fire cannot block the light.
