Tako's Plant Elixir

This activity is a fun and educational nature and science activity suitable for preschool and primary school levels. Children will create their own plant fertilizer using materials easily found at home. Through this process, they will understand the importance of recycling and discover natural nutrients that support plant growth.

Objective of the Activity:

To help children develop sensitivity toward nature and plants.

To raise children's awareness of how recycling benefits the environment.

To help children recognize the nutrients necessary for plant growth.

To allow children to experience simple chemical reactions.

To support their understanding of how natural waste (like banana peels) can be reused.

To encourage children to adopt eco-friendly practices in daily life.

To enable children to understand the scientific process through observation.

To support the development of fine motor skills and hand-eye coordination throughout the activity.

First, the Story

Tako saw Ruka doing something in the kitchen. But her face looked a little sad. He quietly walked over and asked what she was doing:

Materials

Activity

In this activity, children learn how to prepare a natural plant fertilizer using simple materials found at home. First, a clean one-liter glass jar or plastic bottle is prepared. Banana peels sliced into thin pieces are placed inside and water is added..

The lid is closed, and the mixture is left to rest overnight in a cool and dark place. During this time, the banana peels release nutrients into the water.

The next day, the banana peels are removed from the water. Then, one packet of dry yeast and one cube of sugar are added to the mixture. All the ingredients are stirred well and left to rest for another half an hour.

After the waiting period, the resulting liquid is used to water the plants. In this way, children prepare a natural and recyclable nutrient that supports plant growth.
 

Attention

The jar or bottle used in the activity must be clean and should not have come into contact with any chemicals. This is important to ensure the mixture does not harm the plants.

Banana peels should be sliced as thinly as possible and must be fresh. Very old or decayed peels may cause unpleasant odors and bacteria growth.

The jar should be kept in a dark and cool place. Excessive heat may spoil the mixture or cause undesirable fermentation.

After adding dry yeast and sugar, the jar lid should not be tightly closed. It should be left slightly open to allow gas to escape. During this time, avoid shaking or moving the jar.

The resulting plant nutrient should be poured directly onto the soil, not on the leaves. Otherwise, it may cause leaf burn in some plants.

Children should be clearly told not to drink the liquid during the activity, and the process should be supervised. Although the materials are natural, the mixture must not be ingested.

The plant nutrient can be used once a week. Using it more frequently may harm the plants. Guidance from an adult is important for deciding how often and how much to use.

Do not overwater the plants after applying this nutrient solution. Excess water may cause the roots to rot. Only water lightly so that the soil remains slightly moist.

Evaluation Questions

Why did we leave the banana peels in a dark environment? What was the purpose of this step?

What materials did we use in the activity? Do you remember the role of each material?

When were the dry yeast and sugar added to the mixture? Why did we need to wait afterward?

Where did we pour the liquid mixture we prepared? How did we give it to the plants?

What would happen if we gave this nutrient solution to the plants every day? Why should we apply it only at certain intervals?

Do you remember why we shouldn't use too much water when applying the plant nutrient? Why is that important?

Was this mixture natural? Did it contain any chemical substances?

How did using the plant nutrient help support the growth of the plants?
