Gloop “ ” a very silly putty Nathan Herrington | Dina Al saadi | Rahaffairaq
Physical after water was added Characteristics • More liquid than solid • Did not hold shape • Very low viscosity
Chemical after borax was added Characteristics • More solid than liquid • It held its shape for a short time • Higher viscosity • Bouncy • Stretchy
GloovsGloop Glue J J J J J J J J J J J Jj J J Silly Putty More solid High viscosity Blue Not very slimy Bouncy • Liquid • Low viscosity • White • Sticky & slimy • Not bouncy
Why Why Why properties change did the Why Why Why • Borax + glue = chemical reaction • Chemical change • Glue + water (liquid) = more of a liquid • (physical change) • Gloop + food coloring = blue color • Physical change
