answer
what is co?
carbon monoxide
what is the use of the machine?
to filter air
name 3 materials that we used
wire, bamboo, water, mech, acrylic, batteries
How does the machine function?
the paper is burnt in the chamber. the air that is produced passes through the filter and the filtered air is measured by the device.
what are the effects of carbon dioxide?
it is a greenhouse gas that contribute to global warming
what prompted us to make the machine?
we want to reduce the amount of greenhouse gas in our environment
what was our biggest challenge?
OKEMMMMM
what is chemical formula for formaldehyde?
HCHO
what are our controlled variables?
amount of filter inside machine, temperature, amount of organic materials used
how was the filter made?
blending bamboo with water and then slicing into then slicing it into the size we want
how is each science branch applied in the project? (name 1)
physics: creating system for machine
chemistry: research how air will be purified
biology: impact of the machine on the environment and materials needed
ESS: sustainability of the machine and the sustainability of the machine
why did we use bamboo?
bamboo absorbs gases and pollutants in the air during photosynthesis and because of its large surface area, they can trap dust particles
describe and analyze the results. (what results did we receive and what do they mean)
there was a decrease in CO and HCHO concentrations with the filter present. this means that the filter has fulfilled its purpose
what are the dimensions of the machine?
8cm x 8cm x 15cm
name 1 benefit and limitation of the machine.
benefit:
1.filters greenhouse gas
2.made using sustainable materials
limitation:
1. has to be attached
2. can only filter small amounts of gas
