Build a simple experimental model of a single room, human dwelling using a two litre milk bottle as a basic structural framework.
Students perform a simple experiment to measure the thermal efficiency of their house by taking temperature measurements over time after an ice block is placed inside their experimental dwelling and allowed to melt.
Following completion of their individual project, students join a team with the intention of building an improved model which will be assessed for the following:
The above example is intended only as an example of what is possible (thanks to EB):
Groups are required to refine or re-design their model dwelling and to document their reasons and their methods for achieving those improvements.
Each group must produce a video record of their project (see framework below)
There are opportunities for inter-group and inter-class collaboration and competition.
Throughout the project, groups will measure the qualities of their own experimental dwelling against those of other groups - both in their own class and other classes participating in the project(s).
Each student is required to submit an individual project that is the result of their own classwork only.
Parental and/or third party involvement is welcome in the group project.
To be accepted for final assessment, each group project must include a simple written statement of the proportion of work completed by student(s) versus third parties.
Each group must build a single room, model dwelling using a two litre milk bottle.
All models must have the equivalent of a single internal area of two litres volume, and from which the nominated six measurements can be obtained in the described manner.
The milk basic bottle materials can be cut away and/or re-configured in any way, but the overall volume enclosed by the 2 litre bottle must be retained as a single room (not sub-divided into additional 'rooms'). Additional rooms/features may be added using only designated materials. Any such 'improvements' will be ignored for purposes of thermal measuremet but may cout in favour or against the overall score, which includes sustainability, carbon footprint etc.
INJURY WARNING: Most plastic milk bottle sides are soft enough to be very easily cut with scissors BUT a 'starting hole' needs to be punched/cut into each face first, to allow the blade of the scissors to move around and cut the main panels.
The 'starting hole' may best be made in advance by a parent/teacher rather than be done by the student(s).
NOTE: Some other types of plastic bottles are more difficult to cut with scissors (the plastic tends to crack or shatter more easily).
For example, it would be acceptable to cut away all six plastic sides, leaving only a thin skeletal outline, and re-clad the sides/floor/ceiling with cardboard or any other specified materials. Students are free to add openings such as windows, doors and skylights.
So long as only prescribed materials are used, students are free to be inventive in their design/building. Any innovation in the areas of science, technology, engineering, art and/or mathematics will be taken into account by judges.
To qualify, each project must include rigorous and true measurements taken and retained throughout the life of the project (using the values specified in the nominated format).
The centre of each side panel was cut away using scissors to leand a 'skeleton'. Some colourful cardboard sections were taped over the skeleton to form walls and a roof.
The black dots were stuck onto the inside and outside surfaces. An ice block will be placed on the centre of the floor and an infrared thermometer will be used to measure the temperature of each black dot every five minutes. The results will be recorded in a spreadsheet.
Start by writing brief notes in your log book, using the following headings (1 - 10 below)
Before starting your experiment, fill in your video story-board (ask your teacher for a story-board template), with notes explaining what content you will include for each section and how you will shoot the content for that section (including close-ups, distance shots and so on).
Decide what the role will be for each member of your group and for each part of your story-board content before you start creating your movie.
Think about the kind of 'feeling' or 'artistic effect' that you would like your movie to have (should you have a music background or include an interview, or insert images etc)?. Should the music/interview/images be serious, funny.. or have no background music at all?
Maybe you could simply design an artistic image to use at the start/end of your movie, or make a poster to promote your movie?
Describe what your experiment will be a about. Keep it short and simple:
For example:
Our experiment investigates the best way to keep a house cool while making sure that it is pleasant to live in and environmentally friendly.
Write down your hypothesis - a short description of what you are predicting (guessing) will, or will not, happen:
For example:
Provide a link or reference to similar experiments or research that relates to your experiment - including any Internet or text-book references:
For example:
This question was part of the on-line Science Quiz Additional information was supplied here
Describe what you did do, or plan to do, in your experiment in a way that is simple enough for someone else to repeat:
For example:
The plan and design for our house is shown in our movie and in our labelled diagram (below)
Describe which things/values that you will change and what you will measure (and record in your log book)
For example:
Write down all values (table of temperatures) that were taken from the specified measurement points in your experiment:
Temperatures recorded by 'Typhoon Turtles' group
Time | New Ice | Classroom Temp. | Inside Floor | Inside wall | Outer wall | In ceiling | Out roof |
---|---|---|---|---|---|---|---|
09:00 | 08.59 | 19.00 | 19.1 | 19.0 | 19.2 | 19.1 | 19.3 |
09:15 | - | 20.3 | 16.3 | 16.4 | 18.5 | 17.0 | 19.0 |
09:20 | - | 21.8 | 14.5 | 15.1 | 17.2 | 16.1 | 19.8 |
09:25 | - | 22.0 | 16.1 | 15.9 | 18.9 | 17.1 | 20.5 |
09:30 | - | 22.2 | 19.3 | 17.5 | 20.9 | 18.9 | 21.5 |
In summary, we are looking for the house where the ice block takes the longest time to melt that has been built using the most environmentally friendly materials and most liveable design.
To save time and reduce the number of measurements, find a way to answer this question:
HINT1: For each house, how long does the ice take to melt?
HINT2: Dan Meyer - TED Video - Maths Classroom Needs A Makeover
In your log book, create a simple, clear, labelled diagram for the setup that you use for each experiment, and not any changes made to setup since last experiment.
We took measurements of the 'black spot stickers ' attached to the floor and walls of our model. We added a door to our model for this experiment as marked on our plan (also see photo)
Include a screen-grab of the wiki page and/or the quiz page that you mentioned in your EVIDENCE section (above)
For Example:
Figure: Comparing how quickly temperature changes with/without a door
At the end of your movie include photographs of your diagrams, any results or graphs that you created in your log book. Include these photographs at the end of your movie (only if they relate directly to your experiment or have been mentioned in your experiment)
Think about each of the following points.
Write some notes based on the following - your summary MUST include:
At the very end of your movie, create a section titled 'APPENDIX“
It should be obvious to your movie viewers that the stuff in appendix is separate from the main part of your movie (the first 9 subject headings above)
The Appendix should include all of your photographs, pictures of story-board, log book, diagrams and finally, any extra entertaining out-takes and/or bloopers.
HINT: If anyone goes out of frame during a part that you want to include, then simply insert an image or illustration for the period that they are out of frame (leave the voice track running) and then cut back to the live action when they return into frame.
It is possible to use Google Sheets to provide simple forecasts - using existing time-based data to predict the value of unknown, new data: https://docs.google.com/spreadsheets/d/1opF9SxYBF2Hpkjlkjtjz8SDYNSeoJu0ni_e-zXNON80/edit#gid=0

Egain (time and temperature measurements) can be used to help save energy and reduce global warming: https://en.wikipedia.org/wiki/Egain_forecasting
Egain forecasting is a method of controlling building heating by calculating demand for heating energy that should be supplied to the building in each time unit. By combining physics of structures with meteorology, properties of the building, weather conditions including outdoor temperature, wind power and direction, as well as solar radiation can be taken into account. In the case of conventional heating control, only current outdoor temperature is considered
