List three variables that are not controlled HELP PLEASE?

Topic: Hypothesis for kids
June 19, 2019 / By Lynne
Question: Philip, who teaches first grade, believes that educational television programs such as Sesame Street promote reading ability in young children. He announces his hunch to his students and tells their parents about his idea during a P.T.A. meeting. Some parents respond enthusiastically when he asks for volunteers to participate in a three-month experiment to test his hypothesis. Ten volunteers are assigned to the experimental group and instructed to have their children watch the one-hour Sesame Street program each day after school. The parents of ten other students, who are picked at random from the remaining members of the class, receive the same instructions, except that the program they watch is a one-hour non-educational cartoon. After the three-month period, Philip administers a standardized reading test to both groups. He is delighted to find that the average test score of the students in the experimental group is substantially higher than that of the students in the comparison group.

Here are some of my ideas: Average pretest reading levels for each group Other languages spoken in the home Gender - were there more boys or girls in one group Average age in years and months...one group could have had kids who were closer to seven and one could have been closer to just turning 6. Other time spent doing educational activities at home such as flash cards and reading Did the teacher know which groups children were assigned to? He could have treated them differently without intending to. Were there any undiagnosed health or learning problems that may have had an impact on learning?

It depends how long you will be gone. But here are the basics..... For four days add extras if needed Pack in Suitcases • Put names on everything! • Deodorant • Comb/Brush • Shampoo/Soap • Toothbrush/Toothpaste • Razor/shaving cream (if needed) • 3 Sweaters/Sweatshirts/Hoodies – it may be COLD. • 3 pair of jeans/pants/sweatpants • 2 pair of shorts – just in case it is warm • 4 shirts • Sleeping Clothes • Two pair of comfortable tennis shoes/walking shoes • 4 pair of socks. Put one in backpack in case of rain. • 3-4 pair of underwear • Fleece jacket • Outerwear – gloves, scarves and hats • Warm Winter Coat (pending weather forecast) • Umbrella • Poncho • Camera (digital is best)—make sure your battery is fully charged before the trip. Given the weather this time of year, it is best to dress in layers. Bringing only one heavy winter jacket is not the best packing advice. Try to wear a t-shirt, sweatshirt or fleece combination. Spending Money • Water bottle, travel games, books, headsets, pillow, extra batteries, etc. Note: We are not responsible for lost items. Students have and do lose mobile phones, iPods, etc. • Cameras (Digital are best. Film is expensive on the Mall.) • Extra Socks – in case of rain • Rain poncho (purchase at Wal-Mart or Dollar Store) Mobile Phones We strongly encourage the students to limit the use of their mobile phones during the trip. We make this request for several reasons. Snacks and Water We recommend a bottle or two of water for the trip in the backpack. In addition, fruit, Lance crackers, Nutri Grain bars or granola bars make for a great snack item if one becomes hungry during the day prior to the next meal. There will be a lot of walking on this trip and having the snack or water in the backpack is helpful

It'll be hot and humid during the day so I recommend t-shirts and shorts, you'll want a hoodie or light jacket since it can get cool in the evening. Def decent walking shoes, some areas are kind of hilly.Underwear, socks obviously. Possibly a hat if you will be outdoors a lot, the sun can be hot. Toiletries - shampoo, body soap, toothbrush, toothpaste, all the obvious things. You will def want an ID if you have one just in case. DC is pretty expensive so go with more rather than less money. A wallet to keep it in obviously. You might want a small umbrella just in case. Cell phone. It all really depends on how long you will be there and what for, that would be helpful to know.

I don't know if you were looking for this, but the Independent variable (controlled) => which TV show they watched. Dependent variable (not controlled) => the test scores other variables that are not controlled are: 1. The average test scores of the kids before the experiment (unless he went by how much the scores had improved) 2. Whether or not the kids were watching other educational shows besides Sesame Street. 3. How much the kids in each group were reading, learning or playing with letters, etc. which would improve their reading ability 4. Environment in which they watched the shows I can't think of anymore at the moment, hope it helped! xoxox T_W :D
