What is Science? The Scientific Method:
This introductory exploration will develop a student's inquiry skills that are essential for scientific investigation and for every-day decision-making and problem-solving. Students behave as scientists, using the Scientific Method to conduct experiments. They will be encouraged to ask questions as they conduct their own guided research to find the answers.
Designing Experiments/Controlling Variables:
Students will understand the concept of controlled and manipulated variables and identify these variables in their investigations. They will design experiments using Alka-Seltzer, water, and effervescent launchers to test different variables that affect the distance the film canister cap travels.

Mixtures and Solutions
Students will learn that chemistry is the study of the structure of matter and the changes or transformations that take place in it. Students gain experience with the concepts of: mixture, solution, concentration, saturation, physical and chemical changes and chemical reactions. They will develop the skills of investigation in order to build explanations based on knowledge and evidence. Students will use group problem-solving techniques to plan investigations. They will use scientific thinking processes to conduct investigations and build explanations for observing, communicating, comparing, organizing, and relating.
Models and Designs:
The investigations in this unit provide experiences that develop the concept of a scientific model and engage students in design and construction. Through hands-on investigations, students will design and construct conceptual and physical models. They will acquire vocabulary associated with engineering and technology, as well as gain confidence in their abilities to solve problems.
