5E Lesson Plan # 1
AUTHORS' NAMES: Teri Normandin and Nanette Darnell
TITLE OF THE LESSON: Bubble Technology
TECHNOLOGY LESSON (circle one):
Yes No
DATE OF LESSON: Day 2
LENGTH OF LESSON: 45 minutes
NAME OF COURSE: 6th grade science
SOURCE OF THE LESSON: Lawrence Hall of Science GEMS Guide
"Bubble-ology"
TEKS ADDRESSED:
- Science Processes – 6.2 (A) plan and implement
investigative procedures including asking questions, formulating
testable hypotheses, and selecting and using equipment and technology;
6.3 (A) analyze, review, and critique scientific explanations,
including hypotheses and theories, as to their strengths and weaknesses
using scientific evidence and information; 6.4 (A) collect, analyze,
and record information using tools including beakers, petri dishes,
meter sticks, graduated cylinders, weather instruments, timing devices,
hot plates, test tubes, safety goggles, spring scales, magnets,
balances, microscopes, telescopes, thermometers, calculators, field
equipment, compasses, computers, and computer probes
- Science Concepts –6.7 (A) demonstrate that new substances
can be made when two or more substances are chemically combined
and compare the properties of the new substances to the original
substances
CONCEPT STATEMENT:
Bubble solution consists of a gallon of water, a cup of dishwashing
soap, and approximately 5 ml of glycerin. The shape of bubbles
is spherical due to the elasticity of the ingredients. No mater
what size the bubbles, they are always elastic but still fragile.

PERFORMANCE OBJECTIVES:
- SWBAT observe and record the shape and size of the bubbles
- SWBAT investigate and compare objects to use as bubble-makers
- SWBAT create hypotheses about bubble-makers
- SWBAT compare properties of substance when creating bubble solution
RESOURCES:
‡ GEM Guide "Bubble-ology"
‡ 8 oz. Dishwashing
soap per group
‡ 1 gallon container
per group
‡ Water
‡ Glycerin
‡ 1 Graduated
cylinder per group
‡ 1 Eyedropper
per group
‡ 1 Measuring
cup per group
‡ 10 different
bubble-makers
‡ 1 metal pie
pan per group
‡ Newspapers
SAFETY CONSIDERATIONS: There are no safety concerns
SUPLEMENTARY MATERIALS, HANDOUTS: There
are no handouts

Potential Misconceptions |
Two
days before the experiment ask students to bring in materials
that would be possible bubble-makers. |
- What do you think
you could blow a bubble with?
- What do you think
would not blow a bubble?
|
- A ring, straws,
strainer, and tube
- A pencil, rubber
band, and a cup

Write
directions for experiment on the board.
- Make bubble solution-
mix 1 cup of dishwashing soap, 1 gallon of water, and 5 ml
of glycerin.
- Cover table with
newspapers
- Pour two cups of
bubble solution in pie pans
- Test each bubble-maker
in the solution
- Separate the bubble
makers that work from the ones that don't work
- Retry the bubble-makers
that don't work
|
- Does everyone understand
the procedure?
- What is working
as a bubble-maker?
- What sizes are the
bubbles?
- What shapes are
the bubbles?
|
- Yes or No
- Ring, straw, rubber
bands, or strainer
- All different sizes
- Circle, sphere,
round

Ask
each group to present their experiment. |
1. What is working as a
bubble-maker?
2. What sizes are the bubbles?
3. What shapes are the bubbles? |
1. Ring, straw, rubber bands,
or strainer

Responses
Potential Misconceptions |
Engage
the students in group discussion about the ingredients of the
solution. |
- What would happen
if the soap were not in the solution?
- What would happen
if the glycerin were not in the solution?
|
- There would be only
small bubbles or there would be no bubbles.
- No effect or there
would be only small bubbles.

Assess
students by overall presentation and participation |
- After experimenting,
what other object could be potential bubble-makers?
|
