Students will acquire experience with the concepts of a mixture
and saturation.
Students will apply math (measuring) in the context of science.
Vocabulary:
Chemical reaction- The process in which two or more substances combine
to make one or more new substances that have different properties
than the original ones.
Mixture- A substance containing two or more materials with different
properties.
Saturated Solution- A solution in which as much solute as possible
has been dissolved.
Solubility- The property substances have of dissolving in solvents.
Soluble- Capable of being dissolved.
Solute- A substance that dissolves in a solvent to form a solution.
Solution- A special mixture formed when one or more materials dissolves
in another.
Solvent- A substance that dissolves a solute to form a solution.

|
|
6. Procedures/Methods-
|
A. Introduction-
1. Introduce science experiment, focusing on mixtures and solutions
|
|
|
B. Development-
1. Model how a mixture is created and a solution is created.
2. Students create a question and hypothesis for their experiment. |
|
|
C. Practice-
1. Illustrate how important following step-by-step directions is
when measuring and mixing ingredients
2. Group students into teams of four for experiment |
|
|
D. Independent Practice-
1. Students will acquire materials and procedure directions on a
piece of paper.
2. Students will create silly putty by measuring and mixing ingredients
3. Students will work as a team to complete assignment, conversing
through each step |
|
|
E. Accommodations (Differentiated Instruction)-
1. Photographs of step-by-step instructions will be printed and
given for students who need them
2. Vocabulary will be conveyed with an icon for illustration |
|
|
F. Checking for understanding-
1. Teams will share their question and hypothesis with the class
prior to beginning their experiment
2. After teams finish experiments, they will note their data on the
board for sharing
3. Students will complete the conclusion to their hypothesis in their
science notebook. |
|
|
G. Closure-
Students will share what they learned from the experiment, and also
share their silly putty |
|
|
7. Evaluation-
|
Informal assessment will be used during this lesson. Students will
turn in their science notebooks for evaluation of the scientific method
and following directions
