Lesson
During this unit of study two projects are presented for your consideration. If time permits it would be to your advantage to do both; however, your teacher may assign only one of the projects.
As each part is introduced it should be completed in its entirety such that it can be submitted, if requested, at the end of the unit or any time during the unit for evaluation.
To effectively manage a chapter project you should
- set up a chapter project folder or binder
- copy the essential information from each part of the project into your folder
- include diagrams, models, pictures or any other support material
- date and complete each stage of the project
- write any impressions or comments concerning the project at the end of each entry
Select a project below for hints and suggestions:
- Hamburger Disease
- Nitrogen-14 to Carbon-14 Simulation
Hamburger Disease
To complete this project you will require
- graph paper
- graphing technology
Read the introduction to this activity and make a list of the relevant facts for each person: Richard, John and Sadie. It is a good idea to create a table of values for each and graph the data of number of E. Coli /cm2 to time before the party.
At this time, plot the graph for (a) and give a general answer for (b). You are not expected to find the actual functions at this time. The remaining questions will be addressed in later sections.
Nitrogen-14 to Carbon-14 Simulation
Materials required for this activity include
- graphing technology with programming capability
- graph paper
Read the introduction to the project and construct the 8 by 8 square requested. To carry out this simulation you have a choice of either writing a programme for the TI-83 or whatever graphing technology you use or constructing a spinner to simulate the ordered pairs required.
With a spinner constructed, label the eight sections 1 through 8 inclusive; spin it once to obtain the row number and spin it a second time to obtain the column number. Shade the block as requested and continue the required number of times for the table. Be sure to record the number of blocks since blocks may be repeated. For example, if the first spin is 2 and the second is 7, then the block at row 2, column 7 is shaded. If these reoccur in another set of spins it is still counted as one of the required number of blocks. Therefore, for 10 spins you may only cover, for example, 8 blocks.
A suggested program for the TI-83 is available if you are proficient enough to enter it into the calculator click here. Remember the same applies as with the spinner - blocks may be counted more than once.
Complete question (a).
