Learn all about experiments

An experiment is the action and effect of experimenting, there are people who want to innovate and others, simply to know if they really work. To carry out an experiment, you need to have a theory and through the experiment, ratify it.

Experiments are techniques to evaluate the relationship of cause and effect, these can be carried out in a laboratory or in real life situations.

Types of experiments

There are a lot of experiments that can be mentioned. However, we will try to make the list short and include only the most common ones.

Lab experiments

These are done under controlled conditions, where the researcher can deliberately change something to see its effect on something else. Experiments done in a laboratory are more controllable.

Field experiments

These are done to see the effect of this on something. In a way, they are controllable, but they must be done in a natural environment.

Natural or quasi experiments

In this type, the researcher measures the effect of something and sees the effect of this on something else. For this part, there is no manipulation released. This research is about simply measuring the effect of something that is already happening.

What are science experiments? 5 steps to make one

Scientific experiment is called the practical evaluation of theories that have originated in another theory. From that point, hypotheses are developed and the sum of more theories that are later evaluated to generate an experimental chain that will end in a conclusion as a result of all the experiments.

  • Ask a question
  • Research on the topic
  • Make a hypothesis
  • Test that hypothesis through an experiment
  • Analyze data and draw a conclusion

Learn three easy experiments

We will leave you here three simple experiments that you will like to do and you will surely have fun in the process.

The bill on fire

Materials:

  • 1 glass of pharmacy alcohol.
  • 1 empty glass to prepare the mixture
  • Water
  • 1 low value note as a precaution.
  • A pinch of salt
  • Kitchen tongs
  • Lighter

Instructions

1- In the empty glass make a mixture of 50% alcohol and 50% water.

2- Add a pinch of salt for a more dramatic flame.

3- Submerge the banknote in the water with alcohol using the tweezers and light the fire.

The bill will burn in flames until the alcohol is consumed and will eventually remain intact.

Conclusion: This experiment teaches the combustion process and the flammability of alcohol.

Recommendations: Perform these experiments with adult supervision.

Explosion of a bar of soap

Materials:

  • 1 bar of ivory soap.
  • 1 Plate.

Instructions

  • In the microwave, place the bar of soap on a plate.
  • Put two minutes on maximum temperature and enjoy how a white explosion is generated.
  • At the end of the time, take the dish out of the microwave and when it cools down you can make various figures with the explosion of soap.

Conclusion: it is a clear experience of Charles' Law, gas law. According to this theory, a certain amount of gas, with a constant pressure, when increasing the temperature, with it increases the volume of the gas and when decreasing the temperature, the volume of the gas decreases.

Change the color of your plants

Materials:

1 glass container preferably tall.

Vegetable dye

Water

Carnations or any type of white flower.

Get this experiment verified with the following steps:

  • Put water in the glass container
  • Pour the food coloring into the water
  • Put the flowers in the glass container

In a couple of hours you will be able to see the result of white flowers in color. The variability of time in this experiment may be due to environmental conditions or other factors.

Conclusion: it can be seen how water is transported through the stem of the plant. This is due to the xylem, it allows it to reach the leaves and hydrate the petals.

Can I do home experiments?

Of course, experiments can be carried out at home, either to confirm a theory or to create a theory and experiment with it yourself. Experiments are part of everything, even the kitchen you use in your home, at some point it was a hypothesis that, through an experiment, gave results.

Home experiments can even be useful for a birthday present, using:

  • 1 balloon
  • 1 plastic bottle
  • Vinegar
  • Baking soda.

In the bottle, place the vinegar, inside the balloon, the bicarbonate and put the mouth of the balloon in the mouth of the bottle and you will see how you will achieve helium at home, through a homemade experiment.

There are even experiments with milk, you can easily try it from home, this could be a homemade invention that could work for a day of home experiments for children. You need:

  • Milk in a deep plate.
  • Several drops of different colored food coloring in the milk.
  • Run a cotton swab through dish soap
  • And finally, put it in the milk and enjoy the dance of colors on the milk.

Benefits of easy experiments for children

These experiments recommended above can be done by children. The easy experiments for children help them understand complex processes, obtaining as benefits: generating curiosity about the unknown, promoting teamwork, stimulating respect for the opinions of others, fostering a critical spirit when observing results, pronouncing the reflection after drawing conclusions from a topic.

These activities, like experiments, help children engage in learning. If learning is instilled in them by telling them, they could forget, if they are taught, they remember it, but, if they engage in this type of method, they learn on their own initiative since the experiments are of interest to any age, having that expectation of the consequences of experimentation allow children to become involved by their own decision.

In the stage from 6 to 12 years old, it is a great challenge to capture the attention of children, which is why using these types of educational methods helps to surprise them and can be of great help to parents and teachers.

It is important to take precautions before doing experiments with children, the idea is to have fun and generate new knowledge, but with caution.
