What’s Slime?・ It’s made from PVA, borax and water.
PVA
Borax
We changed the reactants
We made slime in a pH indicator.
Experiment 1
We changed the reactants
(1)We changed the concentration of PVA.
(2)We changed the concentration of Borax.

Experiment 2
We made slime in a pH indicator.(1) We made slime in phenolphthalein.
Phenol-phthalein

★BTB★acid basic
☆phenolphthalein☆
Subject from now on
1. We are going to consider how we can change the color of the slime.
2. We would like to investigate more about the character, the structure, and the conditions of making the slime.
Thank you for listening!!!
Big love!
