Class Experience

Students will learn what primary colors (red, blue, yellow) combine to make the secondary colors (orange, green, purple).
Students will name the colors in the rainbow order to help us create a rainbow. 
Students will use fine motor skills to squirt the colors onto their tray.
For the experiment, they will need: -white vinegar (about 6 oz) -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 - about 8 oz which is about half a box!) -cookie sheet (can be lined with foil, but it does not have to be) -6 small containers for the vinegar -medicine syringe, eyedropper, or spoon
Learners will not need to use any apps or websites beyond the standard Outschool tools.
verbal assessment as the students make guess about colors and names the colors we should use in the correct order. 
30 minutes per week in class, and maybe some time outside of class.
Since this class can get a little messy, having a parent nearby is highly recommended.
