Edward P. Jones’ “The First Day” Essay

Edward P. Jones’ â€Å"The First Day† is the recollection of a young girl’s first day of school. Her memory of this particular day is incredible; she remembers each and every event in meticulous detail. Having come from a poverty stricken and uneducated household, this was the most important day of her short five year old life. On this day she began to realize her mother’s resilience and fortitude was all in hopes of giving her the education she deserved and the opportunity to live a better life. The girl’s first day of school is her coming of age in life in which she begins to understand that her education, which her mother has so desperately fought for, will eventually be the separation in their relationship. Her mother made sure to dress her in nice clothes, with perfectly braided hair, and brand new black patent leather shoes to impress the school teachers. She wanted to show that her daughter deserved to be in school and was worthy of receiving a proper education. Upon arriving at school she begins to notice the differences between her mother and the administrative women outside the building. She notices luxuries about the women that she knew her mother could never afford, â€Å"The woman has pearls thick as jumbo marbles that come down to her naval†¦Ã¢â‚¬  (Jones 287). After being informed that she cannot attend Seaton Elementary School because of the neighborhood she lives in, the young girl assumes she will not be attending school after all. But her mom does not hesitate to start off towards yet another local elementary school. At this point she begins to realize her mother’s determination. After arriving at Walker-Jones a new rush of feelings begins to sweep over her. As her mother fumbled to find the registration paperwork she notices a young girl who is clearly better off than she is. Her anger is apparent. She doesn’t understand why this process looks so easy for the girl and why it has been so difficult for her. She senses her mother’s frustration with the forms†¦

How Much Water Is in an Apple Science Activity

Apple-themed activities don’t have to be limited to  art projects  for younger children. There are a number of apple-themed science activities that you can do with older children, too. By questioning how much water is in an apple, older kids can learn many science skills and use their reasoning powers. How Much Water Is in An Apple Apples, like many other fruits, have high water content. The following experiment can help your child not only visualize, but also measure, exactly how much water is in an apple. Goal  of the Activity To create hypotheses and participate in a science experiment to answer the question How much water is in an apple? Skills Targeted Scientific reasoning, scientific method, following an experimental protocol. Materials Needed A food scale or postal scaleAppleKnifeElastic band or a piece of stringApple dehydration log: A sheet of paper or computer spreadsheet with lines for each apple segment, its initial weight, and its weight after two days, four days, six days, etc. Procedure Start the activity by talking about what your child knows about the taste of apples. Different varieties have different flavors, but what do they have in common? One observation may be that they are all juicy.Cut the apple into quarters or eighths and remove the seeds.Weigh each of the apple pieces on the food scale and note the weight on the apple dehydration log, along with a hypothesis of what is going to happen as the pieces of apple are left open to the air.Wrap an elastic band around the apple pieces or tie a piece of string around them. Then, find a place to hang them up to dry out. Note: Putting the apple on a paper plate or paper towel won’t let apple slices dry out evenly.Weigh the apple pieces again in two days, note the weight in the log and rehang to keep drying.Continue weighing the apple every other day for the rest of the week or until the weight no longer changes.Add the beginning weights for all the apple pieces together. Then add the final weights together. Subtract the final weight from the beginning weight. Ask: What’s the difference? How many ounces of the apple weight was water?Ask your child to write that information on the apple dehydration sheet to answer the question: How much water is in an apple? Weights Slice 1 Slice 2 Slice 3 Slice 4 Total Weight Initial Day 2 Day 4 Day 6 Day 8 Day 10 Day 12 Day 14 Final How Much Water Is in an Apple? Initial Minus Final = Water: Further Discussion Questions and Experiments You can ask these questions to stimulate thinking about water in an apple: Do you think drying the apple in a dehydrator to make apple chips would reduce the weight further?What makes apple juice different from water? How much might those ingredients weigh?Would the apple slices take shorter or longer to dry in different places? Discuss the refrigerator, a sunny window, a humid area, a dry area. You may run an experiment changing those conditions.Do thinner slices dry faster than thicker slices and why?
