Mouse Trap Distance Project 2017-2018

Project Description:

This is a performance based assessment, meaning you are graded largely on how your project performs not on the number of hours you worked on it.  A team of two students is allowed if both students produce a working vehicle in each round of competition.    Students will use one Victor brand mouse trap as the energy source to drive a vehicle as far as possible down the hallway.  They will get a maximum of three tries to produce their best distance and that distance will be the basis for their grade.  You must test your vehicle before the due date to ensure it works.     The use of a project from another student from a current or past competition will be treated as any other case of academic dishonesty and will result  in the grade of "Zero" on the project.

You may use any materials you wish as long as those materials do not add energy to the vehicle.  For example rubber bands or springs or rockets that store elastic energy are forbidden.  However, no kits are allowed.  The use of a kit will result in a 50 point reduction in score.  A 90 would become a 40.

Note:   All designs must have at least three wheels.  Two wheel designs have been too unpredictable to be considered for this project.  

Due Dates:        First 50% :    Wed, Jan 3  after  Winter Break. (second marking period)

                       Second 50% :    Mon., Feb 5  (3rd marking period)

Point value:  50  points for the first test output  and 50 points for the second test output., with other point values assigned also.   Example 5 points for drawing and materials list.

Oceanography Explorer Project

This is a research project.  You may submit on traditional paper if desired, but you will receive an extra 3 points if made into an  i- Movie  and submitted on a thumb drive.


Due Date:    TUESDAY, OCTOBER 6

POINTS:  30 POINTS

DESCRIPTION:   In the project you select a place in the world along the ocean environment where you would do original research.   The constraints are that your budget including travel expenses, food, housing, insurance etc is $8000 for an eight week study.

In the project you must state your research hypothesis,  detail your experimental procedure  and then detail your itinerary and document y our expected costs to be under budget.  Your itinerary must include at least three separate locations.   You must include documentation for your expected costs.


This is an experimental design/ research project.  Both aspects will have equal value = 15 points each.  Your hypothesis must be scientific  ( This means there is a way to gather data that will support or refute the hypothesis).   You could study  an ocean animal,  a plant,  an entire ecosystem,  or human interaction in an ecosystem.

Ex.  1.  I will travel the Oaxacan  coast from Puerto Angel  to the Guatemalan border, and study the relationship between the size of  the fisherman's gill net openings and where they fish in relation to population centers.   My hypothesis is that the fisherman with larger openings  will fish outside the major centers of population where they regard the ocean as their private space, while fishermen close to population centers will use smaller openings. 

Ex 2  I will travel the French coast south of Normandy studying the health of  the marine estuary environment.  I will  be sampling both quantity and diversity of species present and comparing to historical data available.  My hypothesis is that encroachment on the marine estuary environment in France has caused a net decrease in species diversity and  total quantity of each species.

SSEP (Student Spaceflight Experiments Program) Project Description

Overview:  The SSEP project is a team project.  Four student team members are allowed per project.  Your objective is to design a testable experiment to include a hypothesis and procedure that could  be performed in actual spaceflight by NASA trained astronauts.    The experiment must be contained within a 0.25 inch inner diameter flexible plastic tube and is approximately 10 inches long.   The tube has up to three separate chambers.  Astronauts will open one chamber to begin the experiment and  open the second chamber to end the experiment.   Furthermore, the design of your experiment must be testable using the existing physics equipment located at JDHS or procured by your team using outside resources.  There is an extensive list of materials that are not allowed to be carried into space and cannot be included in your design.

List of "No Fly" materials

NanoRacks List of Problematic Samples
Revised: September 18, 2014
This NanoRacks List of Problematic Samples provides a listing of samples (fluids/solids) that
can adversely interact with the FME mini-lab’s silicone tube. These samples cannot be used in a
100% concentration; however, these materials may be used on a case-by case-basis depending on
proposed concentrations, volumes, solutions, etc.
NanoRacks therefore asks all student researchers to assess if any of their proposed fluids and
solids are on this List, and if so, contact NCESSE as soon as such a substance is being
considered for an experiment so that NanoRacks can review and rule on whether it can be used.

Chemistry Chap 12 Review Concepts

The chap 12 test will be  of the same format as the quiz (short answer)  and cover much of the same material.  Here is the list of concepts, all dealing with balanced chemical reactions:

1.  moles of X to moles of Y

2.  grams of X to moles of Y

3.  grams of X to grams of Y

4.  grams of X to atoms or molecules of 7

5.  grams of X  to liters of Y for gas at STP

6.  Kgs of X  to grams of Y

7.  Kgs of X to Kgs of y

NEW   NEW  NEW NEW

8.  percent yield.   Given  the actual yield, you calculate theoretical yield and calculate percent yield.

9.  Limiting reagent problem.  You are given two or more starting amounts of reagent.  Figure out  which is limiting and then calculate the amount of product.

Solar Water Distillation Project Physics 2015

Description:  Students will design and construct a solar thermal powered still.

Due Date:  June 1,
One partner is allowed or individual.

1.   The device will change dirty salty water into clean pure drinkable water of low conductivity as measured by a conductivity probe.

2.    Grading will be based upon a 24 hour test period of 90% sun starting Monday, June 1 in a secure area on campus.  In the event of clouding a second test will be performed June 2nd, or when sun is available.

3.  The total area of collector may not exceed 0.36 square meters.

4.  80% of the materials by weight must be  post consumer materials  such as used food containers, cardboard, worn tires,   construction debris, etc.

5.  Value:  This project is valued at 100 points.

6.  The test will be done on grass in the courtyard.

7.  Your project is required to have wind protection for winds up to 30 miles per hour.  There is  10 point deduction for designs without wind protection.  If ballast is your plan you are required to use at least 10 pounds.

8.  The reliance on tape to remove your clean water  will result in a 10 point deduction.  This is an inferior material for a project that generates steam.  Do not tape your glazing to your project body.

9.  A deduction of 10 points will result if your project requires more than 5 minutes to add dirty water, secure the glazing and stake down for wind protection.

10.  Grading will be based upon the production of clean water in mls.

250 ml =  A

200 ml = B

100 ml = C

5 ml = D

Less than less than 5 ml = F

Suggested design elements:

1.  Research the best orientation for capturing maximum sun in our latitude

2.  Do not allow vaporized clean water to escape from your project

3.  Keeping mass low will allow for quick temperature increases.

4.  Selective insulation can prevent heat loss through radiation back into the environment

5.  Some glazing will prevent light transmission.  This is to be avoided

6.  To maximize condensation your condensation surface must be cooler than the vapor inside your project

7.  Here is a link to a small still made from some recycled components
