4. Activity1: Comparing Packing Materials
We placed 2 eggs in 2 different plastic bags, one bag
had biodegradable foam and the other had non
biodegradable foam, the one with the biodegradable
foam degraded and broke down and the other one did
not degrade.
Activity2: Processing biodegradable materials
& comparing their mechanical properties.
We placed 10ml (HCL) in 3 different petri dishes with
different amounts of gelatin in each one, and we
covered one of them which had 20% gelatin to form a
gel.
Activity3: Measuring the degradation rate of
biodegradable materials.
We placed 0.1g of 20% gelatin, 10% gelatin, foam and
capsule gelatin in acid, base and hot water and timed
how long does it take to degrade.
Activity4:Desning a medicine delivery device.
We used sodium alginate to from small pellets
resembling a drug delivery system and tested its
degradation.
