There are many different kinds of expectations that can change how results are viewed. Expecting a reaction to produce a chemical in a certain amount of time can change how results are viewed for example.
A scientist may constantly change the variables being tested or manipulated during an experiment to understand their impact on the outcome. By systematically altering one variable at a time while keeping others constant, the scientist can identify cause-effect relationships and draw conclusions about the phenomenon being studied.
Expectations can influence how individuals interpret and perceive the outcomes of a situation. High expectations may lead to disappointment if the result does not meet them, while low expectations can lead to pleasant surprises if the outcome exceeds them. It is important to be mindful of how expectations shape our perceptions and reactions to outcomes.
An environmental scientist studies the impact of human activity on the environment and works to develop solutions to address issues like pollution, climate change, and conservation of natural resources. They conduct research, collect data, analyze results, and recommend strategies to protect and preserve the environment for future generations.
An environmental scientist is a scientist who studies the environment and its interaction with living organisms. They may specialize in areas such as ecology, conservation, climate change, or pollution.
Bias occurs when scientists' expectations change how the results of an experiment are viewed.

Expectations change how results are viewed
The variable that a scientist observes to change while conducting an experiment is called the independent variable. This is the variable that is deliberately manipulated by the scientist to observe its effect on the dependent variable.
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".
