John’s biology class was studying various ways to recycle materials, including the use of compost as fertilizer. Members of John’s class investigated the effectiveness of various recycled materials in promoting plant growth. John and three members of his lab group decided to compare the effect of compost and commercial fertilizer on plant growth. Three flats of bean plants (25 plants per flat) were grown for five days. The plants were then fertilized as follows: Flat A received 10 grams of commercial fertilizer; Flat B received 10 grams of aged compost; and Flat C received no fertilizer. The plants received the same amount of sunlight and water each day. At the end of 20 days, the students recorded the height of the plants in centimeters.

What is wrong with John's Experimental Design?

a)
1. Sample size too small
b)
2. No repeated trials
c)
3. Uncontrolled variables
d)
4. No control group
e)

Joanna read that certain perfumes would cause bees to leave the hive and act in an agitated fashion. She decided to investigate the response of bees to five different perfumes- Ralph Lauren, Armani, Mark Jacobs, Vera Wang, and the last is an odorless liquid. She placed a saucer containing 20ml of perfume A 10 meters from a beehive. She then recorded the total number of bees that emerged from the hive during a 15 minute interval and made observations on their behavior. Using a 30 minute interval between tests to allow recovery time for the bees, she then repeated the procedure to test the remaining three samples. Each test was conducted on the same day with similar weather conditions. What is wrong with Joanna's Experimental Design?

Sammy wants to see if plants really do grow better in sunlight. He uses 3 plants of the same type and size in 3 locations. Plant A is placed on Mrs. Shaw’s countertop in the center of the room, Plant B is placed inside the cabinet, and Plant C was placed near window sill. After 5 days Sammy measures the growth of each plant and documents it in the table below. What is wrong with Sammy's Experimental Design?

It was a dark and stormy afternoon at Brookland Cayce High School. Students were returning from lunch. Mr. Grivetti sat on his stool with a fresh spaghetti-sauce stain on his shirt, while Ms. Hardin ushered students to their seats. “Mmmmm, what a delicious lunch I just had!” Mr. Grivetti exclaimed. “I’m completely stuffed. How was school lunch today?” His students look at him as if he were crazy. Suddenly, Mrs. Tate knocked at the door. She whispered to Ms. Hardin, “has anyone seen Ms. Fulmer’s lunch? She had spaghetti and meatballs, but it seems to have gone missing.” Ms. Hardin thought for a moment, going back in her memory to think if she had seen anything. She turned to Mr. Grivetti and asked, “Mr. Grivetti, did you see anything? I think you were in Mrs. Fulmer’s room just before lunch started.” Mr. Grivetti widened his eyes a little and quickly said, “No.” He stood up quickly, knocking his lunch box off of the table. When it hit the floor, a sandwich and an apple rolled out. Mr. Grivetti scanned the room, and then asked students, “Does anyone know anything about Mrs. Fulmer’s missing lunch?” Who do you think took Mrs. Fulmer’s lunch? Write a claim that answers the question.

The effect of perfume on the behavior of bees. Description: Joanna read that certain perfumes would cause bees to leave the hive and act in an agitated fashion. She decided to investigate the response of bees to five different perfumes- Ralph Lauren, Armani, Mark Jacobs, Vera Wang, and the last is an odorless liquid. She placed a saucer containing 20ml of perfume A 10 meters from a beehive. She then recorded the total number of bees that emerged from the hive during a 15 minute interval and made observations on their behavior. Using a 30 minute interval between tests to allow recovery time for the bees, she then repeated the procedure to test the remaining three samples. Each test was conducted on the same day with similar weather conditions. Write a hypothesis for the above scenario.

The effectiveness of various metals in preventing rusting of iron. Description: Several weeks after Allen conducted a classroom experiment on the effectiveness of various metals in releasing hydrogen gas from hydrochloric acid, he read that the gas company was burying sheets of magnesium next to iron pipelines in order to prevent rusting. Allen wondered if other active metals would also be effective in preventing rust. To investigate, he placed each of the following into a separate test tube containing water: one iron nail; one iron nail wrapped with an aluminum strip; one iron nail wrapped with a magnesium strip; and one iron nail wrapped in a lead strip. He used the same amounts of water from the same source, equal amounts of the metal wraps and the same type of iron nails. At the end of five days, he described the amounts of rusting either as small, moderate or large. He also recorded the color of the water. Write a hypothesis for the above scenario.

Sammy wants to see if plants really do grow better in sunlight. He uses 3 plants of the same type and size in 3 locations. Plant A is placed on Mrs. Shaw’s countertop in the center of the room, Plant B is placed inside the cabinet, and Plant C was placed near window sill. After 5 days Sammy measures the growth of each plant and documents it in the table below. Based on the data in the graph do we accept or reject the following hypothesis: If plants are place in sunlight then plants will grow better because plants need sunlight to make their food.
a)
Accept
b)
Reject
10.

Sammy decides to test if the amount of sunlight affects the color of plant leaves. He places Plant X in direct sunlight, Plant Y in partial shade, and Plant Z in complete darkness. After a week, he observes the color of the leaves. Based on the observations, should Sammy accept or reject the hypothesis: If plants receive more sunlight, their leaves will be greener?

a)

Accept

b)

Reject

11.

After observing the growth of his three plants, Sammy wonders if sunlight also affects the number of leaves produced. He counts the leaves on each plant after 5 days. Should Sammy accept or reject the hypothesis: Plants exposed to sunlight will produce more leaves than those kept in the dark?

b)

Reject

12.

a)

Accept

b)

Reject
