Today, at science class, we made an experiment, it is about physical properties and mass and stuff like that. We combined iodine, water, vinegar, cornstarch, baking soda, baking powder, and talcum powder, two by two. This is the chart I made aftyer our experiment:
Cornstarch+Iodine: The cornstarch absorved iodine's brown color.
Cornstarch+Water: The cornstarch turned muddy.
Cornstarch+Vinegar: The cornstarch turned muddy.
Baking Soda+Iodine: The baking soda and iodine disolved.
Baking Soda+Water: The baking soda absorved the water.
Baking Soda+Vinegar: When vinegar was added to the baking soda, the baking soda fizzed and made bubbles.
Baking Powder+Iodine:The baking powder and iodine disolved, too.
Baking Powder+Water: The water got absorved, too.
Baking Powder+Vinegar: It fizzed and made bubbles.
Talcum Powder+Iodine: It disolved and turned brown.
Talcum Powder+Water: The water stayed at the top.
Talcum Powder+Vinegar: The vineger push part of the Talcum powder to the top.
I hope I have a chance to make an experiment next time
