• Directions for Card Trick
• Remove the Face cards and the 10s. The Aces have
  a value of one (1).
• Have a student draw a card and look at the card
  and place it on the table ( In the tens place).
  Next, you draw a card and remember the number and
  place in next to the other card (in the ones
  place).
• Multiply the number on your card by 2
• Add 2
• Multiply by 5
• Subtract the difference in your card and ten
  (student may use a calculator if necessary).

3

• Ask for the number
• Have the person turn over the card the that
  should be the number.

4
Here is the Math (Algebra)!

• Let X students card
• Let Y your card
• 5(2X 2)
• 10X 10 - Y

• Math is the language of science.
• Effective science can not be taught without math
  and math should not be taught without science.

There is a crisis in American Education!
Shortage of highly qualified math and science
teachers. A decline in the number of PhDs in
math/science related fields. A decline in the
interest of students for math/science related
fields. A shortage of people entering the
workforce with math/science skills. A lack of the
ability to problem solve.

• The National Science Education Standards indicate
  that "the relationship between science and
  technology is so close that any presentation of
  science without developing an understanding of
  technology would portray an inaccurate picture of
  science" (National Research Council, NRC, 1996,
  p. 190 see also American Association for the
  Advancement of Science AAAS, 1990).
  Consequently, teachers need to be prepared to
  integrate technology into their teaching.

What can I do as a teacher or administrator ?

• Change an attitude
• Workforce readiness college readiness
• Integrate Technology
• Create an environment that uses authentic data
  acquisition, applications to real world
  experiences, problem solving, and activity.

11
Science and Math must work together to

• Improve the quality of education
• Improve the quality of the workplace
• Improve the quality of life
• Increase the interest of students in math and
  science related fields

12
Activities for the Classroom

• Measurement activities
• Graph, Graph, Graph.
• Data Collection Using Probes
• Real World Data from the Internet

13
Data Collection Using Probes

• Advantages
• Time efficient
• Easy to set up labs - Not labor intensive
• Accurate data collection
• Encourages inquiry based investigations and
  student collaboration
• Supports and encourages critical thinking
• Incorporates the use of technology
• Emulates real world experiences
• Authentic assessment
• Disadvantages
• Cost
• Learning Curve

Acid Rain Activity WorksheetName
_________________________  1. (3 points) Access
the site http//water.usgs.gov and click on "Acid
Rain" under "Water Data". Then scroll down and
click on "Primer on acid rain how it is
measured and its effects". Skim through this
site. 2. (6 points) What is acid rain?   3. (8
points) Describe two negative effects of acid
rain.    4. (6 points) In the United States,
where is excessive acid rain the most prevalent?
For what reasons?    5. (6 points) Describe
sources of pollution that contribute to acid rain
formation.   6. (4 points) Access the site
http//bqs.usgs.gov/acidrain and click on "View
and download data on precipitation chemistry
from the NADP/NTN". Then click on "Data". Now
click on WI or another state that your
instructor specifies. Click on one of the
monitoring sites listed, scroll down and click
on "Annual Data". You will now complete the
"Data Selection Criteria" form. Select 1989 as
the start year, 1998 as the end year. For data
type select "Precipitation weighted means
(mg/L)". For report format select "HTML table".
Select "K-12" for intended use and type
"statistics project" for Brief description of
specific application. For seasons to return
select "Annual". Now click Get Data and Continue
if a security warning appears. If you scroll to
the right you will find a list of annual field pH
values which of are interest to us. 7. (6 points)
If you have access to a spreadsheet, you can copy
and paste this table into the spreadsheet. The
only two rows of interest in this project are
the Year and the Field pH row. If you are using a
graphing calculator you will need to enter this
data into two lists. Print out or write the data
values in these two lists to share with the class
later. 8. (6 points) Make a graph in your
spreadsheet or on your calculator showing pH
levels over this 10-year time period. Print out
this graph or draw it on graph paper. 9. (6
points) What does the graph indicate about pH
levels over this 10-year time period?  10. (6
points) Using the equation H3O 10-pH
calculate the H3O for each year. You can do
this for all the data at once by using this
equation in your spreadsheet or calculator. As
pH changes, how does H3O change?    11. (16
points) Now pick another state or monitoring site
and repeat 7, 8, and 9 above for this state.

Be Patientthe download may take a little
time! Copy the graph and paste into Excel for
later use. Tip Once you have pasted into
Excel, always copy data to sheet 2 or 3 to
manipulate date. This will prevent possible
contamination of original data set.
