| Title: Levitating
Magnets |
| Subject: Science
|
| Grade Level: 8
|
| Overview:
|
| Students experiment with magnets and use a use spreadsheet to enter
collected data from experiment. Students generate a bar graph to analyze
data to develop conclusions. Students will identify questions for
further investigation. |
| Approximate
Duration: Two 50-minute class periods |
Content Standards:
- Science as Inquiry
The students will do science by engaging in partial and full
inquiries that are within their developmental capabilities.
- Physical Science
Students will develop an understanding of the characteristics and
interrelationships of matter and energy in the physical world.

Benchmarks:
- SI-M-A1
identifying questions that can be used to design a scientific
investigation; (1,2)
- SI-M-A2
designing and conducting a scientific investigation;
(1,2)
- SI-M-A3
using mathematics and appropriate tools and techniques to gather,
analyze, and interpret data; (2,4)
- SI-M-A4
developing descriptions, explanations, and graphs using data;
(2,3,4)
- SI-M-A7
communicating scientific procedures, information, and
explanations; (1,2,3)
- SI-M-B3
understanding that mathematics, technology, and scientific
techniques used in an experiment can limit or enhance the accuracy of
scientific knowledge; (1,2,3,4,5)
- PS-M-B2
recognizing different forces and describing their effects
(gravity, electrical, magnetic); (1,2,3,4,5)
- PS-M-B4
describing how forces acting on an object will reinforce or
cancel one another, depending upon their direction and magnitude;
(1,2,3,4)
- PS-M-B5
understanding that unbalanced forces will cause changes in the
speed or direction of an object's motion. (1,3)
- PS-M-C6
describing the types of energy that can be involved, converted,
or released in electrical circuits; (3,4)

Interdisciplinary Connections:
- Mathematics : Measurement
In problem-solving investigations, students demonstrate an
understanding of the concepts, processes, and real-life applications
of measurement.
- Mathematics : Data analysis, Probability, and Discrete Math
In problem-solving investigations, students discover trends,
formulate conjectures regarding cause-and-effect relationships, and
demonstrate critical thinking skills in order to make informed
decisions.
|
Educational Technology Standards:
- Identify and define computer and networking terms (e.g. modem,
file server, client station, LAN, Internet/Intranet, data storage
device).
- Demonstrate the operations of a computer (e.g., touch-keyboarding
skills, save, organize and back-up files) and other peripheral devices
(scanner, digital and video cameras, VCR, laser disc player) at an
intermediate level.
- Recognize the importance of information technology and its effect
on the workplace and society.
- Use technology tools (e.g., multimedia authoring, writing tools,
digital cameras, drawing tools, web tools) to gather information for
problem solving, communication, collaborative writing and publishing
to create products for various audiences.
- Communicate information using spreadsheets and databases to
visually represent data and integrate into other documents (e.g.,
entering data, formatting using formulas, analyzing data, and
sorting).
- Determine when technology is useful and select the appropriate
tool(s) and technology resources to address a variety of tasks and
problems.

Objectives:
1. TLW complete magnet experiment (i.e., develop hypothesis, manipulate
variables, collect data, analyze data, draw conclusions, and identify
questions for further investigation.)
2. TLW use technology tools to organize and analyze collected data.

Lesson
Procedures:
Introduction:
1) TTW introduce lesson with a PowerPoint presentation to review steps
of scientific method.
Lesson:
1) TTW group students in groups of 4 or 5.
2) TTW pass out data collection sheets.
3) TTW read data collection sheets to students and answer any questions.
4) TTW pass out magnets and stands.
5) Students complete experiment as instructed.
6) Students work at computers in pairs to organize data and generate
line graphs to aid in data analysis.
7) Students will save work to floppy disks.
Closure:
1) Students display graphs using projector and explain conclusions.
Students will also articulate the questions identified for further
investigation. |

Accommodations/Modifications:
Special Education, 504, and those students with weaker computer skills
will be paired with stronger, self-motivated students for peer support
with technology and to help keep them on task. Instructions/procedures
oral and written to accommodate auditory and visual learning styles.
Hands on activity for kinesthetic learners.
