Cube Size: We measured the height, the length, and the width. Area of Cube: We multiplied the width and the height together and then took that multiplied by 6 because a cube has 6 sides. Volume of Cube: We took the height times the width times the length of the cube to determine its volume. Surface Area to Volume Ratio: We divided the area of the cube by the volume of the cube and got the surface area to volume ratio. Distance of Diffusion: We measured how much the pink went into the cube with a ruler after cutting the cube in half. Rate of Diffusion: We divided the distance of diffusion by 10 min. and got the rate of diffusion. =Protists Lab= Elodea


 * Even though it is sub-aquatic, its’ flowers grow on stems above the water
 * Create a stable habitat for crustaceans and fish
 * They can suffocate a lake by breaking off and floating away

Elodea With Salt


 * The elodea is a rooted plant. It has a long, slender stalk filled with clusters of finely-toothed leaves.
 * Elodea is a very adept at colonization and its ability to self-cut means that some species like Elodea Canadensis, Elodea crispa and Elodea nuttallii are considered noxious weeds.
 * In the wild, elodea also create useful hiding place for fish and other aquatic animals as well as food for crustaceans.

 * Fresh water Animals that posses radial symmetry
 * Belong in phylum Cnidaria and class Hydrozoa
 * They are predatory animals and are multicellular organisms.

=Biomolecules in Foods Lab= 1.

2. All of these biomolecules, including fats, proteins, simple sugars, and starches, where found in at least one of our four foods. Starch is a carbohydrate that is composed of a linked chain of glucose units. It's common in everyday food, like wheat and potatoes. Simple sugars are also carbohydrates, but in their simplest form. Examples of these are monosaccharides and polysaccharides. Proteins are large biomolecules made out of chains of amino acids. Fats are made from glycerol and fatty acid tails. They are generally used to store access energy. We were suprised by the extremely high amount of protein in gelatin. This is because we were generally not aware of what was in it. Also, the presents of fats in steel cut oats also was a surprise.

3. After comparing our data table to other groups data tables, we have seen some differences. This could happen because the amount of food substance could vary between our group and other groups that tested the same foods and the amount of test substance could also vary between groups. The slightly different amounts of food substance and test substance could cause different test results. Also, these tests were based mainly on human observation. This could cause differences because while testing the Biuret Test, one group might think that the substances turned dark purple and other groups might think that it wasn't a dark enough purple, causing different results. =Enzyme Lab=





=Water Inquiry Lab=



=Light Intensity=



=Scientists= 1.) He grew a willow tree in a weighed amount of soil. After five years, he discovered that the willow tree weighed about 74 kg more than it did at the start. As the weight of the soil had hardly changed, van Helmont concluded that plant growth cannot only be due to minerals from the soil. He thought that the extra plant material had come from the water alone.

2.) Joseph Priestley reported the first evidence that gases participate in photosynthesis in 1772. He knew that if a burning candle is placed in a sealed chamber, the candle soon goes out. If a mouse is then placed in the chamber, it soon suffocates because the process of combustion has used up all the oxygen in the air — the gas on which animal respiration depends. However, Priestley discovered that if a plant is placed in an atmosphere lacking oxygen, it soon replenishes the oxygen, and a mouse can survive in the resulting mixture. Priestley thought (erroneously) that it was simply the growth of the plant that accounted for this.

3.) Jan Ingenhousz was a Dutch physiologist, biologist, and chemist famous for proving that light is essential for plants to produce energy, therefore discovering photosynthesis.

4.) Calvin- helped map the complete route that carbon travels through a plant during photosynthesis. In 1948 he traced the pathway that carbon follows to make glucose. The light-independent reactions are actually known as the Calvin cycle.

=Primary and Secondary Activity 1= Places that have a lot of plants such as Tropical Rain Forests, a field of alfalfa, coastal marshes, and sugar cane, Hawaii, have a higher net productivity of certain ecosystems. Also, places near the equator have a higher net productivity.

How do they find the net productivity? What does the net productivity of a certain ecosystem mean? What kind of characteristics of an ecosystem can change or determine the productivity of that ecosystem?

=Discussion Questions= The five elements that make up DNA are hydrogen, carbon, oxygen, nitrogen, and phosphorus. DNA has many functions from day to day. DNA has to do with genetics. Genes are the code to make a protein, which makes what you are. The code is the recipe that makes the protein. Long strands of double-helical DNA can fit into the nucleus of a single cheek cell because it winds around proteins to make tight coils which makes it small enough to be stored there. The purpose of using detergent as a cell lysis solution is the fact that it effectively releases soluble proteins and breaks apart the cell. DNA becomes visible once the alcohol is added because the alcohol causes the DNA to clump together, thus becoming visible. The DNA is visible in this lab exercise because what we see is actually many strands of DNA accumulated together. DNA is referred to as your genetic fingerprint because DNA contains the blueprint to your body and is unique to every individual. One example of how DNA is used everyday is DNA is used in forensics. Police use DNA to claim if a criminal is guilty or not. Also, it can also be used to trace your family tree.
