Dear
Students and Parents,
All
students at Julia Landon College Preparatory and Leadership Development School
are expected to complete a science project. This year students in the eighth
grade may choose from several options for their project. Each option has
guidelines for completion. Student projects will be graded according to
appropriate criteria for the option chosen. By choosing an option, a student is
committing to completing that style of project. Parents must approve the option
chosen by their child. It is each student’s responsibility to choose an option,
obtain parental permission to complete the option, and complete the project
according to established rules and/or policies.
The
options possible include:
o
An individual or a 2 member team science project that follows
the traditional format. Each student will complete all forms required for the
project. All rules for Intel –ISEF, SSEF, and NEFRSEF will be followed. Projects in this option are eligible to
seek entry into the school science fair. Participants of the school science fair are eligible to be selected
to advance on to the DCPS science fair and/or NEFRSEF. Winners at
NEFRSEF may be selected to attend the Florida Science Fair. Rules and
information about forms and dates can be found at http://www.nefrsef.org/ . Minimal teacher assistance will be
available in class and students who choose this option are eligible to meet
with interested and available science teachers for after school coaching by
appointment. Students are expected to present their projects in class
o Toshiba ExploraVision. In
this option, students work on a team of 2-4 students. The team is sponsored by
a teacher from JLCP. Full information can be found at www.exploravision.org . Students
are expected to present their projects in class. Minimal teacher assistance
will be available in class and students who choose this option are eligible to
meet with interested and available science teachers for after school coaching by
appointment. All dates can be found on the webpage.
o
E-cybermission. In
this option, student teams choose to complete a mission in one of several
categories by first identifying a problem in the community and then using the
scientific method to develop a solution. Full information can be found at http://www.ecybermission.com/. Students are expected to present their projects in
class. Minimal teacher assistance will be available in class and students who
choose this option are eligible to meet with interested and available science
teachers for after school coaching by appointment. All dates can be found
on the webpage.
An
informational meeting for parents about the different options will be held on Tuesday,
September 12. It will be held in Room 309 from 3:25 until 4:00.
Please
do not hesitate to contact us with any questions or concerns.

25 point classwork assignment
25 point classwork assignment
The purpose
of this flipbook is to help you keep track of the definitions, examples, and
questions generated by these topics. (In the past, this has been a very
difficult topic for 8th graders.)
Use your FUSION textbook (pg. 350-362) and the ScienceSaurus books to create your foldable.
