- 1 3 1 1 Homer Simpson loves to garden and wants to grow lots of pink flowers for his pal Moe. He bought a special Flower Power fertilizer to see if it will help plants produce more flowers. He plants two plants of the same size in separate containers with the same amount of potting soil. He places one plant in a sunny window and waters it every day with fertilized water. He places the other plant on a shelf in a closet and waters it with plain water every other day. The one without sun dies while the one with sun grows. 6. What is Homer's Independent Variable in the experiment? 7. What is the Dependent Variable in his experiment? 8. What is one constant you can identify in this experiment? 9. What is one error that could have occurred in this experiment? 10. What is one thing Homer could do to improve this experiment to test if the Flower Power fertilizer really worked? 11. What conclusion can Homer make about the Flower Power fertilizer? MO A3. Mrs. Gulliver wants to find out whether or not Miracle Grow really makes plants grow faster. She takes two identical pots, puts 1/2 cup of dirt into each one. Puts 3 pea plant seeds in each one, and tops each off with 1/2 cup more dirt. She waters the plants the same amount at the same time each day. The only differences is that one plant is watered with regular water, while the other is watered with water that has Miracle Grow in it.

- Jenny wanted to plant sunflowers, but wasn't sure of the best place to plant them on her property - so she decided to investigate! Jenny planted 6 sunflowers where they would get sun all day, 6 where they would get some sun and some shade, and 6 where they would be in total shade all day. Jenny watered all of the sunflowers at the same time of day with the same amount of water. After 3 months Jenny measured how tall the sunflowers in each location were. What is the hypothesis that Jenny was testing? Choose all that apply. Question options: A Amount of water affects plant growth B Plant growth is affected by light exposure C Plant growth is affected by the time of day of watering D Amount of light affects plant growth because light is required for photosynthesistwo seedlings that weight 5 grams are planted, each into a pot containing 3 kg of soil. Plant "A" is given 3 grams of nitrogen, phosphorus, and potassium each per year and plant "B" is not. Both plants are kept on the same green house and given the same amount of water and light. After 5 years the plants are allowed to dry completely. the soil and dried plants are weighed again. The soil from both containers weighs 2.8 kg Plant "A" has a dry mass of 6 kg Plant "B" has a dry mass of 2 kg Over the five years plant "A" was given a total of 45 grams of Fertilizer. Describe using your knowledge of nutrient cycles and limiting nutrients, how that small of an amount of fertilizer can result in 4 kg of difference in growth of the two plants. *two seedlings that weight 5 grams are planted, each into a pot containing 3 kg of soil.

- Growers often wrap potted plants in plastic sleeves prior to shipping. If plants remain in these sleeves too long, their leaves curl and fall off. Imagine you are working at a garden center and have been asked to make a presentation to a local garden club.Unit 5 DQ Question: Explain the processes that may cause the leaves to drop and fall.A student groWs four dandelion plants with different amounts of water. The table shows the plants at day 10 and the amount of water each is given daily. Plant Amount of Water per 8. 12 Day (ml) Which observation can the student make about the dandelions? O The tallest plants received 8 ml of water per day. O The shortest plants received 12 ml of water per day. O Dandelions grow best with more than 10 ml of water per day.

- Jim hasn't been having success in growing strawberry plants for the past few years, so he got his soil checked for soil conditions. He received information that the soil was too acidic. He wanted to check if the acidity of the soll was the reason for the unsuccessful growth of strawberry plants. He added lime (adding lime neutralizes acidic soils) to half of his garden. He did not add any lime to the other half of the garden and planted strawberries in his garden. He found that he had juicy strawberry bunches on the side of the garden where lime was added. 1. What is the observation of this experiment? a) Jim does not know how to grow strawberries b) Strawberries do not grow on plants c) There is some problem with the soil d) Jim does not like strawberries 2. What is the control group in the experiment? a) Strawberries grown in the soil manipulated with lime b) Strawberries grown in the soil with no lime added c) Jim, who added lime to the soil d) Strawberries that were not growing in…A healthy red-flowered tulip plant is shown below.
