Subject: Science
Learner Outcomes:
Students will be able to:
1. Identify scientific equipment found in the laboratory.
2. Safety and correctly use necessary equipment to master success
in the laboratory.
3. Use laboratory equipment necessary for this lesson.
Duration of Lesson: One 45 minute class period.
Materials:
1. Beaker
2. Graduated cylinder
3. Triple beam balance.
4. Paper
5. Pencil
6. Handouts
Technology Tools/Course software:
1. Microsoft Word
2. Computer
3. Projector
Teacher Notes:
1. Handouts can be viewed in rich text format which requires acrobat reader.
2. Lab Safety Agreements must be copied,
signed and dated prior to day 1.
3. Lab equipment needs to be set out prior to lesson.
4. Take 6 triple beam balances and place one at each station.
5. Take eighteen 500 milliliter beakers and place three at each station.
6. Fill each beaker with a predetermined amount of water ( such as
10 ml, 50 ml, and 100 ml) and label as beaker number
one, two, and three.
7. Using 6 graduated cylinders, place one at each station.
8. All handouts need to be copied prior to lesson.
Handouts include:
Laboratory Safety Quiz
Laboratory Safety Answer
Key
Lab Safety Agreement
Data Table
Data Table Answer Key
Laboratory Equipment Handout
9. Optional quiz on laboratory safety provide
ample time remains.
10 If Power Point presentation is
to be used, the projector needs to be set up prior to lesson.
Procedures:
1. Equipment is to be set out prior to lesson.
2. Students will review laboratory safety procedures using a safety handout.
3. Students will be introduced to various laboratory equipment necessary
for this lesson.
4. Teacher will demonstrate correct usage for each piece of equipment.
Such as:
A. Using
a graduated cylinder, filled with various amounts of water demonstrating
how to read it using the meniscus.
B. Using
a triple beam balance and a beaker, demonstrate the correct way to read
various weights of water.
5. Allow students ample time to get familiar with reading and weighing
the different amounts of water.
6. Students will be given the laboratory data
table data sheet as a graded assignment for this experiment.
7 Students will be given a handout
showing the tittle of each equipment piece and the description for each.
8. Optional:
Quiz on laboratory
safety
Power Point presentation
will be used to end the daily lesson.
Modifications:
1. Individual IEP's should be considered for addressing special needs.
2. Once mastery of reading and weighing is completed, teacher can
us peer tutoring for help in acquiring mastery for all
students..
Enrichment/Assessment:
1. Students will be using scientific instruments to reinforce their
learning outcomes.
2. Peer tutoring is a great way to build the students self esteem.
