混合顏色並製作出嘶嘶作響的彩虹

****I schedule a few weeks out at a time, if none of the times above work, click the button called "show alternative times" and create a new section. Often other learners will join in after a section is created.****

Welcome to color science!  Your child will gasp in awe when the colors start to fizz on the tray!

In this class, I will guide the students as we do the science experiment together. Students can conduct the experiment alongside the teacher from home or simply observe. There will be time for questions and showing off your experiment as we go. Since this is for young learners and might be a bit messy, having a parent nearby is highly recommended. 

Please bring the following items:  
-white vinegar (about 6oz)
-food coloring (red, blue, yellow) (use the cheap water-based kind for a true red, the organic ones are more purple/pink color)
-baking soda (enough to cover your tray - 8-16oz!)
-cookie sheet (some learners find success if they line it with tin foil, but not essential)
-6 small containers
-medicine syringe, eyedropper, or spoon

After simple introductions, we will gather our supplies and go over some simple classroom rules. 

We will put primary colors in our vinegar (red, yellow, blue) with food coloring and guess what colors they make when 2 are mixed together. 

Then we will see what happens when we add drops of colored vinegar to our tray of baking soda in rainbow order (Shhh!!! Don't give it away!)

At the end, the learners will show off their completed rainbow and tell us the colors they used.
