Be sure to cite your sources at the end of the prelab. You can type your answers to all questions except #1 and #9 directly into this document and then submit via Canvas. Type the answers for #1 and #9 at the end of the document. 1.
Results- This graph shows the amount of time spent in the these areas. This tiny sowbug did much of its time in the light portion of this experiment. The tiny sowbug did the most traveling back and forth from the light and dark areas of the trays. This graph shows the amount of time spent in the areas of light and dark.
Isopods can be born a male then change to a female later on in life. Isopods eat fungi and decaying plant matter. Experimental Design: Testable Question: How will the isopods react to different lighting conditions? Independent Variable: Lighting condition Dependent Variable: How the isopods will react Test: Materials: Scotch Blue Tape 8 ounce water

In our Worm Behavior lab we observed red worm behavior when faced with different stimuli. Each group has their own trays of worms that they'll have to observe. (10 worms per group) Moist and dry paper towels are needed for this lab along with Corn meal, Lemon Juice, and two other liquids of your choice. And you´ll need to have a chart to record your observations on every 10 minutes.
Because carbon dioxide is absorbed by the plant during photosynthesis less carbon dioxide present in the chamber is a sign that photosynthesis is working. The four lights used for this experiment range across the light spectrum on both sides in order to test a wider variety of wavelengths. All lights will be placed directly on the spinach leaf at the same distance so as not to give any spinach leaf a different light intensity, which could affect the data. This experiment will be able to show which light, ranging across the light spectrum, will allow the Spinach to perform photosynthesis more efficiently.
You must have heard a lot about mold remediation nowadays. There is no doubt that a mold remediation is a worthwhile project. Mold growth not just leads to havoc health problems, but can also make your home structure weak. More than likely, the mold you have seen growing in your home is the result of water incursion. Wall interiors, basements, attics, and crawlspaces, are all contributors for water incursion.
The “slime” tore apart when pulled hard and fast. The substance broke apart as the polymer chains were stretched. The substance when pulled slowly did stretch and did not break apart. Slime is a non-Newtonian fluid and therefore has a different viscosity depending on the amount of force applied to the slime. This explains why pulling with more force caused the slime to thicken then break and less force simply increased the surface area or was stretched.
Cleveland Heights High School this fall is presenting “Grease”. The production features Maurice Power as Danny and Flannery Jewell and junior Callie Swaim-Fox as Sandy. Performances will go through November 5- November 8 from 7:00pm. Tickets are $6 and $10, cash or money order only made payable to Heights High School.
Fungi and mold don’t use photosynthesis like plant for food they use their organic environment. Typically, molds secrete a type of enzyme called hydrolytic enzyme, from the ends of the hyphae. Click here to watch a video: https://www.youtube.com/watch?v=Ew0Dvw0ZoX8
Source 1: What makes mold grow? https://explorable.com/mold-bread-experiment Mold is a natural substance that kills germs and helps humans to live a longer and a healthier life. This substance isn't only used for one purpose but is also used in other medicines across the world to save millions of lives. Mold grows naturally in the environment and occurs in nearly every ecosystem in the world.
Research Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases.
Aim To observe the effect of light intensity on the rate of photosynthesis. Hypothesis Light intensity is directly proportional to the rate of photosynthesis. When the light isn’t intense, not many oxygen bubbles will be produced and thus observed. This indicates that the plant will not have enough derived energy from the sun to activate photosynthesis. Whereas, when the light intensity is great, the rate of photosynthesis will be high.
Does bacteria on hands impact with mould growth Introduction: Mold is a part of the fungi family, it grows on almost anything with yeast on it if you leave it out for to long. Mold is often occurs on a yeast product like bread and this happens when the bread is in a warm moist conditions for a period of time like 4-10 days. mold on bread is common because bread provides a desirable source of nutrients for mold. These include the bacteria on the bread and the bread needs to moist and relatively warm and humid for it to take place.
According to Dictionary.com defines the word serve as “to give assistance; be of use; help.” It is easy for me to help my friends, however, I usually put my needs last. I have no problem taking my friends clothes and food shopping, putting the groceries away, even cleaning their home. I have encouraged my friends to continue their education, watch their children, review their papers and offer suggestions for their assignments.
