Lab 1 Intro to Science Essay

The growth and survival of a plant depends on the reactions that occur internally called photosynthesis. Photosynthesis is a reaction that captures the sun’s energy and converts it, water, and carbon dioxide into glucose, with a byproduct of oxygen. Glucose is a sugar that provides energy to allow for a plant to grow and live. This experiment is to test how photosynthesis can be sped up with a home solution. The variable being changed in this experiment is the solution that the plant is being given. In this instance, some of the plants will be given Gatorade, rather than water. The question being asked is, How well will a solution found in the home affect plant growth?

Hypothesis: As the light intensity goes up the abundance of daisy's on The Downs School field will also increase.

6. The most appropriate graph for this data set would be a line graph because it showcases trends and findings within the trends.

The graph that is the most appropriate for this type of data is a histogram because it is used to compare things between contrasting groups.

Upon the completion of this lab, students will be able to perform the following tasks:

Hypothesis: The duckweed will show a small growth increase with very low levels of salinity and then will show a decline in growth rate as the levels of salinity increase.

The black-eyed peas were all exposed to different amounts of lemon juice in each level. Level 1: 0%, level 2: 50%, and level 3: 100%. In level 1 by day 2, the number of black-eyed peas germinated increased greatly, but throughout the rest of the experiment it stayed the same. In both level 2 and 3, 0 seeds were germinated by day 2. During the time between day 2 and 6, level 2’s number of seeds increased from 0 to 8. In level 3 only 1 seed was germinated during that time. The graph supports that the seeds given less lemon juice had more seeds germinated.

Once the plants have sprouted and grown for about two weeks, they were ready for observations. Six different groups in the lab class compiled data by counting each plant of how many tall vs. dwarf plants have grown. A class average was then calculated to have accurate and precise data.

Will talking to rosemary plants cause a larger increase in the plant’s growth speed than singing? It is important for gardeners to know how to make rosemary plants grow as tall as possible because the plant is more often used for cooking than for decoration. The anticipated outcome of the experiment was that singing would cause a larger increase in the growth speed of the plants because of the active genetic response all plants have to high frequency sounds, like singing. To find the answer to this question, three rosemary plants were grown under the same circumstances, other than the sounds they received. One of the plants was sung to everyday one of them was spoken to, and the other received no sound at all. After one and two weeks,

For this experiment, we were testing the effect of the growth hormone IAA on the rate of mitosis in onion roots. We hypothesized that if the growth hormone was added to the onion, the rate of mitosis would be faster than that of the control and our null hypothesis was that differences in numerical results are due to chance only . To test this, filled two cups with sand and put an onion plant in each, then added IAA solution to one cup and control solution (water and ethyl alcohol) in the other. After covering each cup and plant with plastic wrap, we waited for them to grow overnight. When they had done so, we took the plants out of the cups and cut off any roots that had grown, stained them, crushed them, and prepared slide with them, then

In addition to that, sounds at higher frequencies cause a more active reaction in plants than lower frequencies. While different frequencies of sounds may affect all plants, rosemary plants have their own grouping of environmental needs to ensure the tallest growth possible. So, will rosemary plants grow taller when spoken to or when sung to? The expected outcome of this experiment is that singing to rosemary plants will cause them to grow faster because of the gene response to high frequency sounds, like singing. Because rosemary plants are more often used for cooking and less for show, it important to make sure that the plants grow as tall as
