According to the Center for Disease Control and Prevention (CDCP)(疾病控制预防中心), if you don't often wash your hands, you will be affected by viruses(病毒) from many places and make yourself ill. You're at risk every time you touch your eyes, nose or mouth. In fact, one of the most common ways people catch colds is by rubbing(揉) their noses or their eyes when there are cold viruses on their hands. If you don't often wash your hands, especially when you're sick, you may spread the viruses directly to others. You should wash your hands in the following situations:
◆ After using the bathroom.
◆ After blowing your nose or coughing.
◆ Before eating, serving or getting ready for food.
◆ After going to see anyone who is sick.
◆ When your hands are dirty.
There's a right way to wash your hands. Follow these simple steps to keep your hands clean.
◆ Use neither cold nor hot water.
◆ Wash for 15 seconds.
◆ Wash well under warm running water and dry them with a clean towel.

Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren’t very smooth rub together to make heat energy. The faster you rub two things together, the more friction (and heat) you can make. Let’s discover friction!
WHAT YOU’LL NEED:
● Soap           ● Water          ● Your hands!
WHAT TO DO:
1. Make sure your hands are dry.
2. Rub your hands together until you feel the heat of your hands.
3. Now, use soap and water to get your hands very slippery (滑的).
4. Try to make friction happen while your hands are slippery.
5. Please write down what has happened.
LET’S TALK!
Friction is an energy that happens when two things rub together. When friction happens, it makes heat! When your hands are slippery, they won’t make very much friction and your hands won’t get so hot.
DID YOU KNOW?
1. Friction happens when you stop your fast running bike.
2. Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn’t know it.
        ?       
Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not too hot, touch the tires (轮胎) of the car before and after a short drive to see how much warmer they get from friction.

Leonardo da Vinci began painting the Mona Lisa in 1503. He was working on an important painting for a church at the time, but the church painting was not going well. An Italian businessman asked da Vinci to paint a picture of the businessman’s second wife. This is the woman who can be seen in the Mona Lisa.
All in all, the Mona Lisa is a very good example of da Vinci’s work. Da Vinci uses darkness and light in a clever way in the painting.
Da Vinci loved science and math. Right away a person can see that there is a lot of geometry (几何) in the Mona Lisa. The face of Mona Lisa is made of many circles and round shapes like balls. Even her smile can be seen as a small part of a large circle.
The woman in the painting is sitting on a balcony, and mountains can be seen behind her. Da Vinci loved to study rocks and mountains, so these can be seen over and over again in his other paintings.
The woman is sitting with her knees to the side. Her head is turned to look out of the painting. Her hands are held together in front of her. This way of sitting is now used by many artists when they are painting a picture of a man or woman today.
