Example of Experiment Report Text – Experiment report text is a text whose contents are in the form of the results of experiments carried out by the researcher or those who carried out the experiment. This text aims to report the results obtained after conducting a series of experiments and data processing to obtain a conclusion.
The trial report is a form of publication of the findings obtained in an experiment. To make it, there are several important things that must be known such as the structure and several other things that will be explained in this paper.
Experiment Report Text Structure
The trial report is composed of a title and contains two important parts as a framework, namely a general statement and also a description. Each of these sections consists of points and also explanations that support the experiments carried out.
In the general statement section, there is a description or classification whose contents discuss the experimental object in general. This section is composed of background, objectives, and theoretical foundations. The description section consists of tools and materials, experimental steps, experimental results, and conclusions.
Some simple reports have a shorter structure, namely titles, objectives, tools and materials, steps, experimental results and conclusions, while more complex reports may have other sections such as data analysis or discussion, experimental variables, and so on. other.
Features of the Test Report Text
There are several characteristics of trial reports that must be considered and understood, namely:
1. Its nature must be objective
Experimental reports must be objective, which means they must be in accordance with the facts and prevailing theory, not mere estimates.
2. Presenting Facts
Trial reports must be written based on the results of trials that have actually been carried out, there may not be anything that was not done during the experiment, but is written into the report.
3. The contents are complete
The contents of the trial report must be complete and constitute a complete series of experiments carried out, although sometimes there are things that are general in nature, but must be written into the report if indeed it is part of the experiment.
Sample Test Report Text
Here are some examples of simple trial reports that you can use as learning materials or references for compiling a trial report.
1. Experiment Report on Making a Simple Telescope
Tools, Materials, and Purpose
Someone who wants to observe objects in the sky requires a sophisticated tool called a telescope. A telescope is a large binocular used in astronomy. This science studies objects in the sky. Astronomy could not develop properly because many people think that astronomy requires expensive and high-tech telescopes, even though simple telescopes can be made and simple observations can also be made.
To make a simple telescope, the following tools and materials are needed.
- You can buy a LUP objective lens (magnifying glass) or a practicum convex lens (commonly sold at laboratory supply stores) with a diameter of 5 cm.
- PVC pipe and needp (pipe joints) with a length of approximately 30 cm.
- Tools such as a small saw and adhesive glue.
- An ocular lens (you can use a binocular lens or a microscope lens) or you can buy a lens at a laboratory supply store with a diameter of 2.5 cm.
Steps
- Determine the body length of the telescope first with the physics formula that we already know, namely: fob + fok = L.
- Cut the PVC pipe to a known length.
- Place the objective lens into the pipe joint, then connect the pipe connection that already contains the lens to the front end of the PVC pipe that has been measured. Remember the objective lens is always located in front of the eyepiece.
- Attach the needp at the very back end of the pipe.
- Place the eyepiece lens in its need.
Results
Conclusion
To observe distant celestial bodies, you don’t always have to use sophisticated and expensive tools. You just use objects that are easy to get. Before making observations, it’s a good idea to look at the rising and setting times and the direction of the object to be observed.
2. Experiment Report on How to Make a Rainbow in a Glass
Objective
Knowing how the process of the rainbow by using simple tools
Tools and Materials Used
- Enough water.
- Glass cup.
- Scissors.
- Glass (with a size that can fit into the glass).
- Flashlight.
Experiment Steps
- Put the water into the glass cup, then place the glass on the table.
- Place the glass into the glass in an oblique or oblique position.
- Condition the room to be dark by turning off the lights, closing the curtains, and so on.
- Turn on the flashlight and then point the flashlight at the glass that is in the glass.
- Observe the rainbow that appears from the corner of the glass.
- Rearrange the glass angle for different results.
Experiment Results
When the flashlight is turned on and then pointed at the glass which is in a glass filled with water, a rainbow appears from the corner of the glass. This can happen because the light coming from the flashlight is refracted by the water in the glass. Because light has wave properties, meaning that light travels in a straight line, then it can be refracted. Thus, a flashlight can also be used to make a rainbow as long as there is a medium that can refract it.
Conclusion
From the experiment of making a rainbow in a glass, it can be concluded that rainbows can occur due to refraction. Light that comes and propagates straight is deflected by the medium of water so that a rainbow beam forms through the surface of the glass.

4. Make Invisible Ink Experiment Report
Have you ever conveyed something confidential? If so, of course you don’t want other people to know the secret. The following is one way to convey something so that other people don’t know about it. This can be done using ink that cannot be seen by others. You can use this method to convey secret messages to your friends.
First of all, prepare the following tools and materials!
- Lemons.
- Water.
- Spoon.
- Bowl.
- Cotton swab.
- White paper.
- Light bulb.
After the tools and materials are ready, follow the steps below.
- Squeeze the lemon juice into a bowl and add a few drops of water!
- Stir the water and lemon juice with a spoon!
- Dip a cotton bud into the mixture and write a message on a white paper!
- Wait for the juice to dry until it’s invisible!
- To read a secret message that you wrote or want to show it to other people, you can do this by heating the paper held near the light bulb!
After going through the steps above, now you know how to make ink invisible. You can use this method to write something confidential. This invisible ink is a chemical reaction. Lemon juice is an organic compound that oxidizes and turns brown when heated. Diluting the lemon juice in water makes the writing difficult to see when you write messages on paper. Thus, no one was aware of the writing’s existence until it was heated and the secret message was revealed.
Other substances that can work in a similar way include orange juice, honey, milk, onion juice, vinegar, and wine. Invisible ink can also be made by using a chemical reaction or viewing certain liquids through ultraviolet (UV) light.

7. Experiment Report on Making Salted Eggs
Objective
Eggs are a source of animal protein which tastes good and delicious, is easy to digest, and is highly nutritious. In addition, eggs are easy to obtain and cheap. Eggs consist of 13% protein, 12% fat, and vitamins and minerals. The highest value of the egg is in the yolk. Egg yolks contain amino acids that help accelerate muscle growth, as well as minerals such as iron, phosphorus, calcium and B complex vitamins. Therefore, preservation efforts are very important to maintain egg quality. The nutrients in eggs are very easy to digest and utilize.
Eggs are highly recommended for consumption by children, pregnant and lactating women, people who are sick, and the elderly. Storing eggs for a long time without preservation can reduce egg weight and egg whites to become runny. However, preserved eggs can extend their shelf life without reducing their nutritional content. One way of preservation that does not change the nutrition is salting. In making salted eggs, the eggs commonly used are duck eggs because they are larger in size than chicken eggs. Compared to chicken eggs, duck eggs have a more fishy smell.
Ingredients
- Good quality duck/quail/chicken eggs.
- Rub ash.
- Red brick powder.
- Kitchen salt.
- Clean water to taste.
Tools used
- Plastic bucket.
- An earthen pot or cauldron.
- Stove.
- Mixer.
- Jar or egg holder.
Ways of making
- Choose good quality eggs.
- Clean the eggs, then wipe thoroughly.
- Sand the entire surface.
- Make a dough consisting of a mixture of salt, ashes, red brick cement with a ratio of 1:2:1.
- Add enough water.
- Wrap the egg 1-2 mm thick.
- Store the eggs in a jar or other air-resistant container for 7–15 days.
Conclusion
- The taste produced between duck, chicken and quail eggs is different. Duck eggs are saltier than chicken eggs and quail eggs. Therefore, duck eggs are more widely used as a raw material for salted eggs because the process is faster, duck eggs are tougher, and taste better than chicken eggs and quail eggs. Why are duck eggs salted faster? When compared to chicken and quail eggs, duck eggs have larger pores. Therefore, the duck egg salting process is faster.
- Salted eggs are stable, they can be stored without experiencing the process of destruction.
- With salting, the fishy taste of the eggs will be reduced, not smell bad, and taste good.
- Salt provided. The higher the salt content, the longer the salted eggs will last, but the saltier the taste will be.
