TSOTS: Lab Report

Hypothesis: If music affects the germination of seeds, then the seeds exposed to Post Malone’s music will germinate faster.
Control: The type of seeds,  number of seeds, and environment
Variable: Type of music/no music
Justification of hypothesis: Post Malone’s music is faster and will vibrate the seeds
more and they’ll grow faster. We wanted to test this because music sometimes helps
us work so it might help plants grow.
Why did you choose this as your hypothesis?
We chose this as our hypothesis because we thought the vibrations of Post Malone’s
more intense music would shake the plants out of the seeds.
Procedure:
Materials:
  • 45 broccoli seeds
  • 3 solo cups
  • Saran wrap
  • Two sets of earphones
  • Two phones for playing music
  • Misted Water
  • Paper towels

Steps:
  • Assemble “Seed Growing Area”
    • Use rubber bands to make two layers of saran wrap (the first layer with a small dip in the middle for the seeds and the second needs to be tight for the vibrations to move through it)
    • Add a piece of paper towel between the layers to hold in moisture
    • Put 15 seeds on top of the paper towel under the second layer of saran wrap
    • Secure saran wrap
    • Tape earbuds to the top layer of saran wrap with the part the sound comes out of facing the seeds
    • Repeat above steps two more times (the last time don’t include earbuds)
  • Plug in devices with music to each of the earbuds
  • Play music for 10 hours each day
  • Open saran wrap daily to mist seeds with water (then close it again)
  • Record data every couple days
Data and Results:
  • This table shows how well each seed group grew over a time period of twelve days.
  • It's relative to each other.
  • We chose this graph because it’s best for showing change over time.
  • The first day no seeds sprouted.
  • By the third day the control had 11 sprouted seeds, the seeds exposed to Taylor Swift music (TSM seeds) had 8 sprouted seeds, and the seeds exposed to Post Malone’s music (PMM seeds) had 9 sprouted seeds.
  • On the fifth day the PMM seeds and TSM seeds were slightly shorter than the control seeds.
  • On the seventh day the TSM seeds were taller than the PMM seeds and the control was even taller than the TSM seeds.
  • By the tenth day the control seeds had grown a lot (about 1-1.5 inches) and the other groups hadn’t made much progress ad even began to wilt.
  • The twelfth day showed that the controls seeds grew even more and the other ones had declined and were basically dead.
Conclusions:
Our results show that our hypothesis was incorrect. The plants exposed to the music had stunted growth and eventually died while the control group grew. We think that we had these results because the vibrations disrupted the growth of the seeds instead of accelerating it. In future experiments we’d like to try other types of music to see if we get the same results. We could make our experiment better by measuring the growth of the seeds on a more strict schedule. We could also try to get the seeds more exposure to the music to see if the results are more apparent. With the information from this experiment others could decide avoid exposing their plants to music or maybe try exposing weeds to music because based on our experiment music seems to have negative effects on seeds.
Seed germination K-W-L
What do you know about seed germination?
Most seeds need time and a moist environment to sprout then they need sunlight, water, space to grow, and time to grow.
What do you want to know about seed germination?
We want to know what type of music makes seeds grow the most.
We want to know if seeds will grow better in certain environments since seeds don’t need sunlight.
What did you learn about seed germination?

Taylor Swift’s and Post Malone’s music have negative effects on seed growth.

Angiosperms are plants that have flowers and produce seeds. Angiosperms are found everywhere, and our Brassica Oleracea is an example of one! This species is just one of 300,000 species that falls under this category. Angiosperms are unique because of the way they reproduce. There are both male and female parts, the male part is called the stamen, and the female part is called the carpel/pistil. The stamen is made up of the anthers (the part that creates pollen) and the filament (the part that holds up the anther). The carpel/pistil is made up of the stigma, style, and ovary. The stigma is the sticky part on top if the long tube called the style, which leads to the ovary. The ovary is where the ovules or female egg cells are held. Other important parts of flowers are petals, even though they are not sexual. Petals help attract pollinators, such as bees, birds, and butterflies, so pollen can be spread from plant to plant. This aids the process of fertilization. In fact, without pollinat...

Abbie Weimer- Blog Post #3: Biogeochemical Cycles and our Plant

Our plant hasn’t grown much this week, but it seems to be liking its new environment. The leaves are looking a nice shade of green, and the broccoli plant doesn’t seem to be withering at all. It is about 4.5 inches now, and its roots are beginning to grow deeper into the soil we planted it in. Overall, our plant is thriving. Our broccoli plant participates in the movement of water in the biosphere every day. It absorbs water through its roots in the soil, and that water is used to make sugar, which is the plants food. The excess water is then released into the atmosphere as water vapor, through a process called transpiration. Our plant is growing rapidly because of this. All plants are a part of the carbon cycle. Our broccoli plant and the rest of the plants in the world take in carbon through their leaves and use it to make food. This process releases a byproduct of oxygen into the atmosphere, allowing other organisms to breathe. In addition, when the plant dies or is consu...

        Like all living things, our Brassica oleracea (broccoli) plant depends on and is affected by many things. These things can be living or not. Some abiotic factors our plant depends on for survival are sunlight, water, soil, carbon dioxide, nitrogen in the form of nitrates, space to grow, and the right temperature. Some biotic factors that affect our plant are other plants in the area, animals, fungi, and bacteria.         I know our plant is engaged in competition because there are many other plants near it that are in the same niche, like other broccoli plants and grass. Our plant is competing with these other producers for the resources of sunlight, water, and space.         In the struggle for these resources, the "winners" are the plants that continue to grow and thrive. The "losers" are the plants that wither and die from not getting what they need to survive. It's not always clear ...
