What are examples of scientific observation?

Take the ball, drop it from a certain height (measure it) and measure the time it gets to the ground

This is a scientific observation, in this case a very simple experiment giving at least the average ball speed.

If you want to be more beautiful, you can use the camera and strobe to measure the position of the ball every 100 milliseconds or every 10 milliseconds.

In this case, you can estimate the local velocity and acceleration of the ball by plotting the position and time chart.

Basically the experiment is scientific observation. This is as simple as dropping a ball from the table or measuring the spectrum of the star.

Scientific methods include a series of procedures that scientists use to conduct experiments. The term "observation" has two meanings in the scientific way. Firstly, there are scientists who observe the world as it leads to hypothetical theory. This is the first step in the scientific approach and can be presented in two ways: nature observation and gradual observation. Secondly, there are two kinds of observations, qualitative and quantitative, when collecting data in experiments using scientific methods.

Scientific methods are a series of steps followed by scientific researchers to answer specific questions about nature. It involves observing, making assumptions, and doing scientific experiments. Scientific research begins with observations and casts doubts about what is next observed. The steps of the scientific approach are as follows. The first step in the scientific approach is to observe what you are interested in. If you are working on a science project, this is very important as your project hopes to concentrate on what attracts your attention. As long as it is what you really want to know, your observation can be anything from plant movement to animal behavior. This is the idea that you come out of your scientific project.

What is the hypothesis? Hypothesis (complex hypothesis) is a description of recommendations for observation. The definition depends on the theme. For example, in science, assumptions are part of the scientific approach. This is a prediction or explanation by experimental test. Observation and experimentation may refute the scientific hypothesis, but it does not prove it completely. For example consider the possible relationship between good sleep and getting good grades. The null hypothesis states that "the number of hours students sleep is unrelated to their grades," or "there is no correlation between their sleeping hours and grades." Experiments validating this hypothesis include collecting data and recording the average sleeping time and performance of each student. If an 8 hour sleeping student is better than a student who usually takes 4 hours of sleep or 10 hours of sleep, that assumption may be rejected.
