Suds or Duds?
In this activity students investigate the effect of hard water on soap. They compare soap in water with soap in water plus Epsom salt. Epsom salt is made of a chemical called magnesium sulfate. When magnesium sulfate is dissolved in water and added to soapy water, the magnesium combines with the soap. This combination is actually a new substance that doesn't dissolve well in water. The common name for this substance is soap scum. Since it can't dissolve in water, the soap in the soap scum can't get back into the water and can't make bubbles.

Racedrop Raceway
In this activity, students create a 'racetrack' picture and cover it with a piece of wax paper. They add a drop of water and attempt to make the water drop follow the racetrack by tilting the paper. This works because the water beads up on the waxed surface, rather than wetting it, like regular paper. This illustrates how polar water does not mix with the nonpolar wax.

Testing Water?s Skin
In this activity, students drop water onto a penny, counting how many can be added before they spill off the side. Then the experiment is repeated, only this time a small amount of detergent is placed on the surface of the penny. Students learn about surface tension and the effect of detergents on surface tension.

Water Walkers
In this activity, students explore surface tension in water. Some insects literally walk on water. They can do this because of their light weight and broad support. The surface tension in the water is great enough to support the insects. Students in this activity try to fashion their own water walkers made from aluminum foil.

Zippy Zappy Boats
In this activity, students make small plastic boats from a piece of Styrofoam. One has dish soap added to its back edge. Adding soap disrupts the arrangement of the water, and the water molecules near the boat have a harder time sticking to one another, making it possible for the boat to go forward.

Crystal Stencil Stars
In this activity, students use a saturated solution of Epson salts to make artistic stars. The star shapes are cut from paper and painted with the saturated solution. As the solution dries, the Epson salts recrystalize, creating beautiful crystals all over the surface.

On the Moooooove
In this activity students place drops of food coloring on the surface of various types of milk. They then touch the center with some detergent on end of a toothpick. The food coloring spreads out most in the skim, least in the half & half, and somewhere in between in the whole milk. Since milk is made mostly of water and fat, the food coloring looks different in the different milks because the food color mixes easily in water but not in fat. So the most mixing is in the skim milk which has the most water and the least fat. The least mixing is with the half & half which has the least water and the most fat. The food coloring moves differently in the three types of milk when the detergent is added. This also has to do with the way detergent acts in different mixtures of water and fat.

Avogadro?s Bubbly Adventure
Small amounts of gases are soluble, or dissolve, in water.,Two of these gases are oxygen and carbon dioxide. For,example, carbon dioxide gas is what gives soft drinks their ?fizz?.,And fish use oxygen dissolved in water for their body chemistry,,much like humans do. When there is not enough oxygen dissolved in,the water, fish can ?suffocate?. In this activity students study the,solubility of gas in water at different temperatures to see whether temperature changes this property.

If Mixing Is Urgent, Try Detergent
Normally, oil and water do not mix together very well. This fact makes it hard for water to wash away oily dirt. Detergent can help water and oil mix together. This mixing helps the water wash the oil,away. In this activity students observe the effect of detergent on water and oil.
