Chemical Reactions

I have been putting off doing experiments with the boys.

This is not good. Experiments are the fun part of chemistry, especially since we do "easy" ones with only household substances.

The experiments below were from:

Janice Van Cleave's

Chemistry for Every Kid

100 Easy Experiments that Really Work

(one of the things I like about Janice's experiments is that, unlike others we have tried, most of them do work!)

The ones are the tray are for finding starch,

the pennies on the plate are for making the pennies green with vinegar,

the egg in the jar is shown closer up, below.

 

 

close up of the bread with a drop of iodine on it

the iodine turned blue showing there was starch present

 

 we also did one for

Curds and Whey

 

 add vinegar to milk and stir, let it sit

the curds will separate from the whey

 Naked Egg

  

put an egg in vinegar

watch and see what happens over the next 24 hours

 

 

 the vinegar has "eaten" away the shell of the egg

  

 and left a rubbery feeling egg

 

this is the membrane of the egg after we broke it in the sink

We did a few other experiments also, but these are the ones I took pictures of.
