1. Topic

Scientific Method/Experimental Design
AIM: How can we construct an experiment based upon the scientific
method? 


2. Content

Students will have to be familiar with and define the following
key vocabulary terms
Key Vocabulary:
1) scientific method
2) hypothesis
3) experiment
4) data
5) theory
6) experimental group
7) control group
8) independent variable
9) dependent variable 


3. Goals: Aims/Outcomes

1. The students should be able to implement the steps of the scientific
method to solve not only sciencebased problems, but everyday problems
within the framework of realworld scenarios.
2. The students will be able to adequately answer questions from the
Living Environment Regents that will require them to formulate hypotheses
and construct experiments based upon their understanding of the scientific
method and the key components of an experiment.



4. Objectives

NYS Living Environment Core Curriculum: Key Idea 3; Performance
Indicators 3.1, 3.2, 3.3, and 3.4.



5. Materials and Aids

1)Scientific Method Worksheet containing key vocabulary terms and
practice problems.
2)Regents questions for group practice. 


6. Procedures/Methods

A. Introduction
Students will be reintroduced to the concept of the scientific method.
The students will be introduced to the the methods 5 parts:
1) Determining the problem or question.
2) Development of a hypothesis.
3) Design an experiment (control group, experimental group, dependent
variable, independent variable) to test the hypothesis.
4) Conduct the experiment and collect the data.
5) Draw conclusions from the data
10 minutes



B. Development
Students will be presented with a real world problem (that they
already may be familiar with) where they will have to apply the scientific
method:
Why is my mobile phone bill higher this month as opposed to last month?
Students will be asked if they ever had to use the scientific method
before in their daily lives? Under what circumstances?
10 minutes 


C. Practice
Students will be divided into groups where they will be presented
with the same 4 Regents questions where they will have to use their
knowledge of the scientific method and experimental design. Each group
will have 10 minutes to answer each question. After 10 minutes have
elapsed, the students will be stopped and 5 minutes will be taken
out to compare the answers of each group and clear up any misconceptions
about the question. They will then move on to the next question where
they will be given the same amount of time to work on the question
as the previous question. 


D. Independent Practice
Students will be given a Scientific Method worksheet for homework
practice. Where they will have to apply the same principles for solving
a problem or constructing an experiment as the did in the group activity.
If the group activity ends with time to spare, the students will begin
the homework assignment. 


E. Accommodations (Differentiated Instruction)
1. Varied Regents Questions based on the scientific method and experimental
design.
2. Flexible Grouping.
3. Labbased problems vs. outside world problems



F. Checking for understanding
Have the students come up with a real world problem that they use
the scientific method to solve. The students indicate the 5 steps
of the method in their solution. 


G. Closure
Summarize lesson by reviewing the steps of the scientific method.
