Controlled experiment.
The thing you change is called the independent variable and the constants are the dependent variables. By only changing the independent variable, any results can be attributed to this.

Experiment
An experiment involves three types of variable.The independent variable is the one you are investigating. It is the one which you deliberately vary in the experiment. You should only have one independent variable.The dependent variable is the variable which you measure to get your results. Often there is only a single dependent variable but there can be more.All other variables must be controlled ie kept constant so they do not change the result. There are usually many control variables in an experiment.

Observing involves noticing and recording events or phenomena without changing them, while experimenting involves manipulating variables to test hypotheses and observe the outcomes. Observing is passive, while experimenting is active in nature.
All science involves observations. A scientist is either observing the world as it is normally, or is changing something and observing the results of the change. The "change something and observe the results of the change" is called an "experiment". If you're not observing something, then you are not doing "science".

A reflection experiment involves observing how light or sound waves bounce off a surface and change direction. By studying the angle of incidence and the angle of reflection, researchers can better understand the behavior of waves and how they interact with different materials. This experiment is commonly used in physics and optics to explore the principles of reflection.
If an object is moving at a constant speed but is accelerating, then its direction of travel must be changing. This means that even though the object is moving at a consistent rate, its velocity is changing because acceleration is a vector quantity that involves both speed and direction.
The constant changing in the form and structure of rocks is called rock cycle. It involves processes like weathering, erosion, deposition, and lithification that transform rocks from one type to another over time.
A controlled exeriment involves changing one factor and observing its effect on one thing while keeping all other things constant.For example,say you want to know if putting an aspirin in the soil will make flowers more colorful. So you grow a group of plants, put an aspirin in the soil, and the plants produce very colorful flowers.
In the scientific method, the experiment is a controlled procedure designed to test a hypothesis by collecting data. It involves manipulating one variable while keeping others constant to observe the effects and draw conclusions. The results of the experiment help determine the validity of the hypothesis.
The essence of an experiment is that the researcher manipulates one or more variables to observe the effect on another variable, allowing for establishing cause-and-effect relationships. In contrast, an observational study involves observing and analyzing existing data or naturally occurring phenomena without intervention from the researcher.
Observing involves you to see the changes or responds the living things or cells given to you, you'll have to look closely and classify what you saw.
The laboratory experiment involves a total of 20 mice.
