Jenny was a 13 year old girl with blond hair and blue eyes. She had gotten out of her last day of school and was free for the summer. Two of her friends were going to the nearby beach to do some swimming and enjoy the sun. Jenny went with them and when they got there the beach was very full and there were people everywhere. They changed into their bathing suits and went to the water. The water was very cold. They chose not swim and walked to the sand. Then they laid down on some towels and enjoyed the sun. After several hours Jenny and her friends fell asleep. They woke up and the sun was beginning to set. When Jenny sat up she found that it was painful to touch her skin. When she looked down she saw that she had a very bad sunburn. Her friends were also very badly sunburned so they went home. Jenny's mother gave her a cream to put on the sunburn. Afterwards she felt a lot better and went to sleep.

How did Jenny notice the pain on her skin and how did she get the pain?

You couldnt survive without your skin. It has many important functions. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. The skin helps maintain a constant body temperature. It keeps the body cool in two ways. Sweat from sweat glands in the skin evaporates to cool the body. Blood vessels in the skin dilate, or widen. This action increases blood flow to the body surface. This allows more heat to reach the surface. The heat is then able to radiate off the body. The opposite happens to retain body heat. Blood vessels in the skin constrict, or narrow. This decreases blood flow to the body surface. This reduces the amount of heat that reaches the surface. When this happens, less heat can be lost to the air.

Josie started planning her new garden in the winter. She chose flowers and vegetables that could grow in her area. She looked through the seed magazines. She ordered the tastiest kind of each vegetable and the prettiest kind of each flower. She talked to a friend about her plans. It seemed like the snow would never melt. But Josie didn't have to wait for spring to get started. Six weeks before the last frost, Josie planted seeds indoors. The tiny seedlings pushed up through the soil and began to grow. Finally spring arrived. Each day, Josie moved the seedlings outside for a few hours so they could get used to the cooler temperatures. Josie worked in her garden, digging the soil. She added a special growing mix from the garden store to make the soil better. When everything was ready, she removed the seedlings from their trays and planted them in her garden. The warm sun and rich soil helped her vegetables and flowers grow.
How did Josie determine what to plant in her garden?
