# How to do the best science for kids with plant breathe in the simple water bottle [#1 experiment for kids ]

Table of Contents

We plan the experiment to investigate the breathing process of the plant leaf. We are familiar that the plant gives oxygen to us for breathing and it takes back carbon dioxide. Is it true? Here we explore our understanding of the said topic by doing a simple experiment. You can use this scientific method as a science for kids. What is the purpose of science for kids? from the simple experiments, they should learn the beauty of nature. This science for kids should be encouraged by teachers and parents.

Teachers and parents should work together to design and construct science for kids. In the early beginning, kids do experiment with the things they observe from nature. Learning of science starts from the observation of nature. Whenever they observe new things, they try to ask questions. As a parent and teacher, we should encourage their curiosity on nature. This is the first step for science projects for kids.

## 1. How does a plant breathe?

Plant breathes through the leaf. Then immediately ask, where is the nostril? we breathe through our nostrils. How the plant leaf breathe? it breathes with the help of micropores in the leaf. If we use a microscope, we can see the micropores clearly. This is called stomata

In the daytime, it takes carbon dioxide and gives back oxygen to the environment. In the nighttime, it does in reverse order. This is simply called the breathing process of the plant.

If we take the good plant leaf, we can design well science for kids. We will see more detail about the experimental conditions in the coming sections.

## 2. How do humans breathe?

Humans breathe through their nostrils. oxygen along with other air molecules go to the lungs. This is called the inhalation process. The waste air carbon dioxide sends back through the nostril. This is called the exhalation process. Even though we sleep also, this process goes on. This is the basic essence of life.

## 3. Why do we need to breathe?

As discussed earlier, life starts with the breathing process. It is the first most interaction and exchange of matter with nature. Scientifically, Our cell needs fresh oxygen for living. In the Vedic term, it is called prana. Oxygen air molecules are not prana. It is something else from a spiritual point of view.

## 4. What do plants need to grow?

The plant needs micronutrients, minerals, carbon dioxide, and water for growth.  A non-pollutant environment also required for good growing plants. Plant biologist analyze the assay for growing plants.

Altogether, how do design science projects for kids? As we know leaf is a main responsible element in the plant for breathing. In our upcoming experiment, we take an average medium-size fresh plant leaf for Kids Science Project.

## Material required for the experiment: (science projects for kids)

1. 500 ml Conical flask                                  1 no
2. Water                                                        500 ml
3. Plant leaf (fresh medium size)                  1 no
4. Two-hole rubber cork                                1 no

Standard Operating Protocol: science for kids

1.   Take a well-cleaned conical flask and add 450 ml of water into it.
2.   The top of the conical flask is fixed with a two-hole rubber cork.
3.   Place one hole of the rubber cork with plant leaf. plant leaf’s stem must immerse in the water (2/3 of the stem should be in the water)
4.    Place another hole with a bent glass tube. (glass tube should not touch the water)
5.    Air is sucked out slowly from the conical flask by using the glass tube.
6.    Now, if you observe very closely in the bottom of the leaf’s stem, you can see the air bubbles coming out.

Note: You take one parameter as a variable. Please don’t take more variables.

Observation:

You can observe the breathing process of the plant leaf. It is helpful for elementary-level school students. They are learning about plants in their environmental science topic. Why are plants required for our life?. If the plant is not happy and healthy on our planet earth, then what will happen on the earth?. If elementary school student observes this thing from their own, they will understand science in the best way. Now the question is, how to take these simple experiments to the next level?. It is discussed in the following section.

## Further Experiments:

High-grade student needs little advance science project problem. With this same experiment, we shall add a little more material as follows:

## Material required for advanced experiment:[Science for kids]

1. Wax candle                                                     1 no
2. One jar with one opening                                1 no
3. Plastic tube                                                     1 no
4. Three-hole rubber cork                                  1 no                                  (instead of two hole rubber cork)

## Standard Operating Protocol: Advanced School Science Method {little more advance than science for kids}

1.   Take a well-cleaned conical flask and add 450 ml of water into it.
2.   Top of the conical flask fix with three-hole rubber cork.
3.   The first hole of the rubber cork places with plant leaf. plant leaf’s stem           must immerse in the water(2/3 of the stem should be in the water)
4.   The second hole is placed with a bent glass tube. (glass tube should not touch the water). Air sucks out slowly from the conical flask.   After sucks out the air, you can close the glass tube.
5. The third hole connects to the jar by using the plastic tube. After this, you place the candle inside the jar and flame it. When you start the experiment, don’t forget to close the jar’s opening.
6.  Now, if you observe very closely in the bottom of the plant leaf’s stem,        you can see the air bubbles coming out. It passes through the plastic tube.   Then the air enters into the jar, it switches off the candle flame. The best result from the experiment is possible under the sunlight and without any air leakage.

Note: You take one parameter as a variable. Please don’t take more variables.

## Observation from the Advanced level School Science Project:{advanced science for kids}

How does the flame switch off? what did you understand from this process? It switches off due to the increase in the level of carbon dioxide. But the advanced part of this experiment, you should do under the observation of elders or adults.  If there is any leakage in the system, you will not get the desired result. If you do with almost care, you will get the desired result. More experiments are available in this blog.

If you are interested in science experiments, please comment to us below. Then we will post in our upcoming blog posts.

Key Note: If you are using medium size leaf, then you take the jar and candle in the simple assumption. Because we get only a small amount of carbon dioxide from the photosynthesis of one single plant leaf. I am telling again. The second part of the experiment is needed more advanced training.

## How to make a sience project ?

Before doing any science fair project, just you conduct small literature search. you can do in google also. then you plan your experiments.

## What plants need to grow ?

Micro nutrients, Minerals, Carbon dioxide, and Water.

## How plants grow ?

Growing plant undergoes different stages before reaching the final stages. It varies from one plant spices to another.

## When conducting a scientific experiment, which of the following is tested?

• Literature search
• Plan the experimentation
• Check the availability in simple labs
• Check raw materials
• Conduct series of experiments
• Draw conclusion from experiments

## Which organisms transform nitrogen to a form that is useful to plants?

Micro organisms in the soil

Botany

## Do plants need water ?

Yes, water is very essential substance for growing plant.
