Comparing the Effects of Fertilizer A and B on Marigold Seed Growth

This experiment aims to determine which fertilizer, A or B, promotes taller growth and faster sprouting of marigold seeds. The process involves placing seeds in separate planters with controlled soil and watering conditions. Each planter will receive either Fertilizer A or B, prepared according to package directions. Measurements will include plant height in centimeters and the days taken for sprouts to appear. Observations will occur daily, with results recorded in a table to compare the effectiveness of both fertilizers.

  1. Design a Lab • I would like to know which fertilizer works best, Fertilizer A or Fertilizer B. Design an experiment to test the 2 fertilizers What am I testing? How will I measure it? How often will I measure it? What will I use to measure? What are my variables? What is a control?

  2. Design a Lab Purpose: To find out if fertilizer A or B works better. Design an experiment to test the 2 fertilizers.

  3. Design a Lab Hypothesis: If I conduct an experiment using fertilizer A and B, then I will determine which causes the plant to grow taller and sprout sooner.

  4. Design a Lab Materials: Marigold seeds Fertilizer A Fertilizer B Water 3 gal jugs. 3 egg crates Soil Measuring spoon Ruler

  5. Procedure • Place 3 tblsp of soil in each planter. • Place one seed in each planter, be sure to cover the seed with soil. • Control: place 1 tblsp of water in each planter • Fertilizer A: mix 1 gallon of fertilizer according to package directions. • Give 1 tblsp of water to all planters receiving fertilizer A. • Repeat steps 4 and 5 using fertilizer B. • Place in sunlight. • Observe planters each day for sprouts, and measure height in cm, record results in table.

  6. Design a LabHeight in Cm Plant 1

  7. Design a LabSprouts Seen Plant 1

  8. Height in Cm/ days to sprout Plant 1

  9. Height in Cm/ sprout seenDay1

  10. Design a Lab Question? • Will changing the water temperature affect how quickly a gummi bear dissolves in water? • Will a dismembered gummi bear dissolve faster than a regular gummi bear? • Does the color of gummi bear affect how quickly it dissolves? • Will sugar coated gummi bears disslove quicker than not sugar coated gummi bears?
