Materials
Candy with a colored coating, like Skittles® or M&Ms® (4 different colors)
Rubbing alcohol or isopropyl alcohol
Coffee filters (2)
Tall glasses or plastic cups (2)
Pencil
Ruler
Tape
Foil or paper plate
Table salt
Water
Toothpicks or cotton swabs (4)
Measuring cups/spoons
Clean pitcher or 2-liter bottle
Procedure
1. Cut coffee filters into rectangles measuring 3 cm by 9 cm
2. Put 4 drops of water equally distant on foil
3. Made 4 pencil dots and labeled the colors
4. Dipped toothpick in one sample of colored water and dabbed the color onto the pencil dot for that color. Let filter paper dry & added more color to each dot 3 times
5. Made the salt solution
6. Poured salt solution into glass
7. Tapped a strip to the pencil and rested the pencil on top of the jar so that the strip hung into the jar
8. Remove the paper from the glass and place it on a clean surface to dry
Prediction
