Based on closed reading, summarize what a polymer is.
- distilled water
- evaporating dish
- plastic bag
- Obtain about 10 Orbeez beads.
- Place them on the balance and find their dry mass.
- Place them in a plastic bag.
- Add 1/4 bag of water and see them grow.
- Place your name(s) of the baggie and wait for three (3) days.
- Place the grown Orbeez on the balance and find their wet mass.
- Calculate the percent of increase in mass (water absorption).
- Place Orbeez on an evaporating dish.
- Re-dry the beads overnigh.
- Find the redried mass
- Determine is any material is dissolved.
