What can you do with milk & vinegar?

The children came to school with many wondering questions when they saw the front table with milk, vinegar, measuring tools and a bowl on it.

The children followed the very precise procedure in our Science experiment. 

Action/Explore:  Boil a cup of milk. Measure 4 teaspoons of vinegar into mug.

 

Pour milk into mug and stir ingredients together.

 

Use a strainer to drain excess liquid out.

 

Scoop the solid out.

After all of the liquid was drained from the solid, the kids formed the 'dough-like' substance into a shape of their choice by using a cookie cutter. They made tree ornaments.

When we completed the experiment, we talked about what we made. The children at this point, didn't know that they made plastic. Further exploration online was required to fill in the gaps. They also made the connection to our symmetry unit...the ornaments are 'equal shmequal!' 

Discover/Explore/Reflect:  So many changes happened during our experiment! We made plastic like in the olden days!!
