Objectives
(1). To build infrastructure in order to teach an
Earth Science course (2). To write a lab manual
for the Earth Science course (3). To develop a
new course on Global Change
3
Objectives
(1). To build infrastructure in order to
strengthen the delivery of an Earth Science
course Reason? (1). History of Earth Science
teaching in HBCUs (2). Total student per year
about 200
Science majors 10 (5) Non-science majors,
non-education 50 (25) Education majors,
in-service teachers 140 (70), African American
98 Over 30 years responsible for education of
140,000 students (gt90 are African American)

Objectives
(2). To write a lab manual for the Earth Science
course
Part of the lab manual is on Rocks And Mineral
Labs For Non Science Majors
7
Reasons
(1). Science background of students is very weak
Science Majors Non-Science Majors
8
Reasons For Writing These Labs
(2). Failure to get students interested in Earth
Science labs using traditional brief techniques
(From Tarbuck and Lutgens, 2003)
9
Reasons For Writing These Labs
(3). Requirement by the state to teach rocks and
minerals in elementary and middle school science
classes (4). Understanding rocks and minerals is
essential to comprehending Earth System Science
10
Our Goal
(1). To teach them the basics (2). To turn their
interests on
11
Results Of Applying This Method
(1). Students interest has increased (2).
Students learning has improved (3). Students
self-initiation has risen

Assignment 02 Mineral Characteristics SCI 205,
Earth and Space Science Jackson State University,
Jackson, Mississippi Instructions Please go to
the following web sites www.google.com Make a
search about the minerals listed below. Summarize
the information you gather for each mineral on
one sheet of paper. Some of the information you
may want to include are One or more photographs
of the mineral Physical properties Chemical
composition How they form Occurrence (where they
are found) Do they have any industrial
use? Minerals Amphibole Biotite K-Feldspars Musc
ovite Quartz Olivine Opal Plagioclase Pyroxene Tal
c Topaz
Procedures
(1). For each lab, we give an assignment to
students to search the subject on the internet
before they come to the lab
Benefit It opens students to available
information
13
Procedures
Benefit It increases communication
(2). Students Observe properties they have
searched and compare with samples they see during
lab hours
14
Procedures
(3). Students record their observations
Benefit It provides a record of students own
observations for class discussions
15
Procedures
(4). We discuss each sample with students after
they have finished their observations (5). We
ask students to provide the results of their
search as a lab notebook (6). We reward students
for their activities
16
Rocks And Mineral Labs
(1). Physical properties of minerals (2).
Silicate minerals (3). Non-silicate
minerals Optional mixed-mineral lab (4).
Igneous rocks (5). Sedimentary rocks (6).
Metamorphic rocks Optional mixed-rock lab
17
Lab-01 Physical Properties Of Minerals
Assignment 01 Search on physical properties on
the internet Students learn how to look at a
sample (for many this is their first
experience) Students learn how to make
observations and identify physical properties of
minerals

32
Objectives
(3). To develop a new course on Global
Change Reason? We felt we need an ESS
course The course was developed Offered last year
to 8 students
33
Future Direction for our Earth Science Course is
to Developed
(1). Additional labs related to our
environments (2). Data Processing and
interpretation labs
34
Overall Direction for Jackson State is to
establish a degree program in ESS
This is to be done through a collaboration
between Jackson State and Penn State funded
recently by OEDG grant from the NSF
