"If you can't explain it simply, you don't understand it well enough" - Albert Einstein
Science explains HOW things happen in the world.
Science explains HOW things happen in the world.
Scientists are great at being observant and naturally have curious minds. Scientists question everything around them to better understand how and why natural phenomenon occur in the world. They are able to elaborate the how's and why's through scientific investigation & engineer design better models, advanced technology, and more to make life of higher quality for everyone.

Followed by an observation, an investigation is designed to answer a question and is executed to draw conclusions from the data obtained - data is the evidence! The sequence in scientific investigation has set a foundation to allow all scientists to complete systematic research, study, and make predictions to answer questions and solve problems in science & engineering.
We scientifically investigate on a daily basis!

Examples of how we investigate scientifically:
Pattern seeking.
Exploring and observing.
Modelling.
Classifying and identifying.
Fair testing.
Why is Science Important?
Why is Science Important?
Science is the systematic study of structure and behavior of the physical and natural world through observation, experimentation, and the testing of theories against the evidence obtained.
It all begins with a curious mind.. making observations and asking questions.

Drawing Conclusions with Evidence by Analyzing Data
Drawing Conclusions with Evidence by Analyzing Data
A developed hypothesis or prediction will be tested and data will be collected. The data (quantitative and qualitative) is the evidence to formulate reasoning and accept or reject the initial hypothesis or prediction.
Scientifically Explain your Results with Claim, Evidence, and Reasoning in your writing.

Claim -a statement answering the question.
Evidence -scientific data to support the claim.
Reasoning - elaboration on how the evidence justifies your initial claim.
An example of C.E.R.
An example of C.E.R.
Claim -Students score higher on assessments when they get 8 or more hours of sleep the night before.
Evidence - After analyzing the data table of results from th experiment, the following evidence was observed.
Students who slept 1-3 hours the night before an exam scored very 30% or lower. Students who slept 4-7 hours before an exam scored in the mode range (31%-79%). Student who slept a minimum of 7.5 hours or more the night before an exam scored the highest (80% or higher).
Reasoning - The quantitative data from the experiment concludes that the claim "students score higher on assessments when they get 8 or more hours of sleep the night before" can be accepted. The claim is true because in the scientific investigation, the group of students who slept 8 or more hours scored an accuracy of 80% or higher. That accuracy score was higher compared to the two groups who slept a different range of hours.
