You have three options from which to choose for
this task. Each interdisciplinary tasks requires you to make connections
between mathematics and science. Each task involves plant life and the
making of a scale drawing. Choose one of the following:
Option 1: Planning a Terrarium - You are interested in building a terrarium.
Find an aquarium that could be used as your terrarium or as a model for
your terrarium. You are just making plans for the terrarium, but if you
have an old or unused aquarium available, you might actually make one. Use the procedure below to
make your plan.
- Measure and record the length, width and height of your aquarium. If you
don't have an aquarium available, decide upon the dimensions you would like
to have for your terrarium. Place measurements in your science log. Compute
the perimeter and area of the bottom of your aquarium. Show formulas and
substitutions in your science log. Use the calculator to make the
computations.
- In your science log, make a list of the plants you wish to put in your
terrarium. You may need to research lighting, water and soil requirements
and plant sizes before deciding what plants you will use. Include all your
research in your science log.
- Make a scale drawing of your terrarium plan. Indicate the scale used.
- Compute the estimated cost of making your terrarium. Detail the costs in
your science log. Include the cost of the aquarium, soil and plants.
- Write a one-page explanation of your plan. Be sure to include
information concerning the four steps above.
Option 2: Planning a Room Greening - You would like to add green plants to a
given room. Locate a room in the school building, a local office, or at
home that you could use for this task. The room, of course, should have a
source of light. Although you are just making plans for this room greening, you may wish to actually
carry out the plan if permission is granted you to do so. Use the procedure
below to make your plan.
- To decide how much space the room provides, measure and record the
length, width and height of the room to be used for the greening. Place
measurements in your science log. Compute the perimeter and area of the
floor of your room. Show formulas and substitutions in your science log.
Use the calculator to make the computations.
- In your science log, make a list of the plants you wish to put in your
room. Research lighting, water and soil requirements, plant size and cost
of plants before deciding what plants you will use. Include all your
research in your science log.
- Make a scale drawing of your greening room. Include plants, windows,
large furniture, etc.
- Compute the estimated cost of actually carrying out your plan. In your
science log, make a table detailing these costs. Remember to include the
costs of plant containers, soil and actual plants.
- Write a one-page explanation of your plan. Be sure to include
information concerning each of the four steps above.
Option 3: Planning a Landscape - In this option, you are required to provide a
plan for landscaping a defined area. The area could be a portion of your
school grounds, your own space at home or some space in your city, town or
village. Use the procedure below to make your plan.
- Decide the spot for which you will do a landscape plan. Find the
dimensions and area of this spot. Place measurements in your science log.
Show how you arrived at its area, including any formulas that were used.
- In your science log, make a list of the plants you will use. You may
need to do some soil testing and research to determine which plants will do
best in the spot you are landscaping. Include in your science log any
information you used to determine the plants you would use.
- Make a scale drawing of your landscaped area. Include all structures
such as sidewalks, fences, existing plants and plants that you plan to
plant. Indicate the scale used.
- Compute the estimated cost of carrying out your plan. In your science
log, make a table detailing these costs. Remember to include costs for
plants, fill dirt (if needed) and other materials.
- Write a one-page explanation of your plan. Be sure to include
information concerning each of the four steps above.
Note to the teacher: You may wish to have the students make a two- to
three-minute presentation, including visuals, in lieu of the one-page explanation
of their plan. If you do this, you will need to alter the scoring guide.
