Outside calendar or even in conjunction with it, plan on and set up a few topical field trips around your community. Learning by experiencing life at preschool age is extremely important and it is a great way to keep your preschoolerís attention.
As you work with your calendar and do a little brainstorming as you check out each month and topical days or seasons they have to offer, begin making a rough draft or list(s) of all materials that will need to support your preschool educational goals that you have established. You can refine list later.
As you begin to stockpile your material that has come from your lists, donít forget to use any and all of items that you can around house. Save boxes, plastic jars, lids, cans, anything colorful that you think you might use. Donít limit your imagination. There are ideas galore out on web! Use it. Have fun and enjoy journey.

How does oil & dirt get washed away with soap?Written by Dr. George Grant
Continued from page 1
In this case, when soap is applied to oil and grease, lipophilic parts of soap will attach itself to non polar molecules of oil. However, other component of soap, hydrophilic component, will be left on surface. When water is applied onto this surface with a sponge, hydrophilic component will be attracted to water molecules and is lifted from surface, together with oil. This way, both oil and soap is removed with wipe of sponge. At same time, because soap molecules have been combined with oil, other soap molecules will also be attracted to it. This is why you can see clusters of oil that are surrounded by soap within water that has been used for washing. Of course, once soap has been used up to attract oil, more soap would need to be added to work on access oil.
In conclusion, our lives have been made cleaner and easier through wonders of a simple substance called soap. Without it, we would be having a difficult time removing dirt, oil and grease in our everyday cleaning.
