What is Science? Science is a way of learning about the natural world.
What types of skills do scientist use? Scientists use skills such as observing, inferring, predicting, classifying, and making models to learn more about the world.
Observing Observing means using one or more of your senses to gather information.
What are your senses? Your senses include: sight, hearing, touch, taste, and smell.
What is a quantitative observation? Quantitative observations deal with numbers or amounts.
What is a qualitative observation? Qualitative observations deal with descriptions that can not be expressed in numbers. Ex: Noticing a bicycle is blue.

What is classifying? Classifying is the process of grouping together items that are alike in some way.
Explain making models. Creating a representation of a complex object or process.
What is scientific inquiry? Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence they gather.
What is a hypothesis? Hypothesis is a possible explanation for a set of observations or answer to a scientific question.
Hypothesis MUST be testable. Researchers must be able to carry out investigations.
Variables Variables are factors that can change in an experiment.

What is technology? How people change the world around them to meet their needs and solve practical problems.
What is the goal of technology? Improvement
