Regarding how the structure and understanding of the experimental report can be seen at this link. Meanwhile, this article will describe a collection of sample experimental report texts with various topics, starting from the examples of scientific/complete experimental report texts below.
Example of Complete Experimental Report Text (Scientific)
The complete structure following the standards of scientific writing from the experimental report text includes objectives, theoretical studies, tools and materials, procedures/works, results of observations, discussions, conclusions, bibliography. The following is an example of a complete test report text.
Effects of Oil Spills on Wildlife Life
Purpose
It knows the impact of oil spills that often occur due to various errors that occur in the transportation process and oil drilling in the waters on the life of wild animals.
Theoretical review
Oil is one of the ingredients that humans widely use. The definition itself means a liquid that is insoluble or miscible with water but soluble in organic solvents. Various forms of oil are very beneficial for our life. There is oil that can be consumed or used as fuel to utilise energy. However, oil can damage the environment if not managed properly because it does not mix with water. At the same time, most of our life forms need water, including ourselves (humans) and wild animals.
Talking about the life of wild animals, what is meant by wild animals is various animal lives in the wild that are not interfered with by humans. That is, these animals are part of an unspoiled environmental ecosystem and can live independently without human intervention. Simply put, animals are not kept or cultivated by humans. As thinking and intelligent beings, we must take care of our existence. In the end, these animals also have their role in the environmental ecosystem that we live in. Without the safe life of wild animals, the human environment is threatened.
Tools and materials
In an experiment or experiment that will be conducted to determine the impact of an oil spill on animal life, the following tools and materials are needed.
- Water
- Liquid soap
- Cooking oil
- Toothache
- Two pieces of feathers
Procedure/How it Works
- Make a table with the properties of water and oil on poultry feathers with the following criteria: absorbent, non-absorbent, and damaged or not.
- Pour water into a transparent bowl.
- Dip the feathers in the water.
- Note how water affects feathers: absorb, or not absorb, damaged/no?
- Mix the oil into the water.
- Dip the second feather in water that has been contaminated with oil.
- Note how contaminated water affects feathers: absorb, or not absorb, damaged/not?
- Try cleaning bristles that have been affected by oil-contaminated water using soap and a toothbrush.
- Record the results of experiments to clean fur contaminated with oil.
Observation result
|
Experiment Object |
Changes That Happened |
|
Water |
Water is absorbed by the fur, only changes shape when wet and doesn't break, once it dries it returns to its whole shape |
|
Oil |
Water does not absorb well, fur looks more worn and damaged |
|
Soap |
Soap can clean the oil, but the hair is already damaged and can't really return to its original shape |
Discussion
The two substances that were experimented with turned out to have very different properties from each other. Water does not damage and actually cleans some of the dust that has settled in the fur. Meanwhile, the oil makes the fur unable to absorb water so that it becomes shabby and even damaged; even after trying to clean, it still doesn't help completely. For more details, the following is the presentation of the analysis results on water and oil.
- Water absorbs into the hair and does not damage. In fact, it can clean or refresh the hair when it is dry.
- The oil makes it impossible for water to absorb into the fur and damage the coat.
- Feathers dipped in oil-contaminated water can be cleaned, but not completely. The fur doesn't really return to its original shape.
Conclusion
It can be concluded that oil spills on the water are detrimental to wild animals in nature. The conclusion is drawn from how oil makes birds' feathers unable to absorb water. In fact, water is one of the sources of animal life. These creatures certainly do not have soap to wash off the oil in the wild. Even if we as humans help clean it up, the result will not be the same as the original. Therefore it is better to prevent oil spills than to clean them.

Sample Text of a Short Experimental Report on Plants
This simple model experiment report only uses two main parts of the text: a general statement and a description (the description can be divided into several parts). The following is an example of a short test report text.
Hibiscus Flower Dissection Experiment
General Statement
Flowers have fairly complex anatomy but are simple in dividing tasks for each part. Through observation or observation, we can clearly see the various outer parts of the flower, such as the crown, petals, and flower stalk.
But we can't really see the inside like the ovule, pistil, and flower base. Through experiments to dissect or cut flowers, we can really know empirically how the actual shape of the flower parts.
Description
Hibiscus Exterior (Sterile)
It appears that the flower has a beautiful flower crown that becomes a lure so that insects can touch the fertile parts of the flower (stamens and pistils) so that the flowers can reproduce. Meanwhile, the flower petals that used to cover the crown are still visible at the base of the flower. The flower stalk also stands upright, supporting the flower with a complex anatomy.
The Inside of the Hibiscus Flower (Fertile)
This part is the most interesting part when cutting or dissecting flowers. It can be seen that the pistil has a hollow part and is indeed shaped like a hose that can channel something (stamens) into it.
At the base of the pistil, we can see the ovule that the stamens will fertilize. Without dissecting it, we cannot see this part. Meanwhile, in this surgery, some pollen was also found that had been attached to the base of the pistil. The shape is not really visible, but with the help of a magnifying glass, it is clear that the small object stuck there is the stamen.
Sample Text of Experimental Report on Food
Cooking Fries that are Crispy on the Outside & Soft on the Inside
Purpose
It makes french fries that are crunchy on the outside but still soft and tender on the inside.
Tools and Materials
Potatoes, kitchen knife, sugar, water, cooking oil
steps
- Boil 3 cups of water until cooked and mix half or quarter of the sugar into it until the sea.
- Peel the potatoes then cut them into small pieces and lengthwise using a kitchen knife. Be careful with this process, or ask someone who is skilled at using a knife to help.
- Soak the cut potatoes in warm sugar water and boil for 15 minutes. This is to allow a small portion of the sugar to soak into the surface of the potato and result in a caramelized outside but perfectly cooked inside and absorb a little more water.
- Dry the boiled potatoes on a tray lined with cooking paper (without colouring). This is done so that the water in the potatoes is reduced, so they will be crispier when fried.
- Fry the potatoes for 10-15 minutes over low heat to ensure the inside of the potatoes.
- Fry over high heat for 2-3 minutes or just enough to make sure the outside of the potatoes are crispy, paying close attention to the colour of the surface of the potatoes, don't let them burn.
Results
Potatoes fried using this method are crispier on the outside and slightly sweet on the outside. It appears that the potatoes get fried to a golden brown due to the slight caramelization of the icing. The outside of the potato is crunchy and has a complex, uneven texture.
Conclusion
The process required to make this dish may be a bit more complicated. But, after trying, it is not that complicated and is still possible even to be applied in daily cooking. The result is also worth fighting for because it makes french fries even more delicious with a few other steps from the usual way.
