Amaryllis

What a pleasant site for February! This big red bloom brightens the gray days of winter.  My mom bought me the Amaryllis Red Lion Indoor Growing Kit for Christmas.  The kids and I planted the bulb right away and watched the green growth for the last month or so.  What a beautiful reward!

This is living science at its best, beginning botany.  This project is listed with Lesson 7 : Roots in Exploring Creation with Botany.  It also goes along the Lesson 3:Flowers and others. 
The kids will remember this experiment, especially since I am taking pictures for their notebooks.
If you live in the north, you still have time to dig up some flower bulbs out of your flower garden and force them.
Botany is better indoors this time of year.

Acid Experiment

Acid Experiment

For homeschool science we tested some acids in a baking soda saturated solution. 
First, we made the baking soda solution by adding as much baking soda to a cup of water as would dissolve in it.   We added a few drops of an acid and watched the gas bubbles.  We charted the strength of the different acids.
One interesting comparison was the strength of the white vinegar next to the apple cider vinegar.
We got the bowl out to test a larger amount of acid (just for fun).  It bubbled up out of the jar producing much carbon dioxide. 
Since we had our acids out we decided to use the red cabbage indicator. We made a red cabbage indicator with the last of the garden’s red cabbage.  I cooked a few large leaves in a 1/2 cup of boiling water until the water became dark.  The red cabbage indicator will turn pink in an acid an blue in a base.
What fun!
