Science and Technology People apply or use science knowledge all the time, but they don't always know or think about it.
Scientists know exactly what is happening when soap combines with dirt and grease.
They can use this knowledge to make better soaps or other cleaning products. You just use the product and know that it works. But sometimes it is good to know a bit more about the science in our daily lives. Doing many things can be easier if we understand a little about why we are doing them in a certain way. Talking to others about things and events can be done more clearly.
