5.) Measure out 20ml of water from 4 different parts of the wetland and place it into four different beakers. Measure the temperature with the thermometer and record the results

The data for Pond 5 were taken first on August 5th, with a temperature of 85.5°F, and wind was headed in a northern direction. Since Pond 5 is quite deep, the group took a small boat out into the middle of the pond about 15 feet away from the shoreline where the water is clear. The data for Pond 3 were taken on August 10th, temperature at time of experimentation was approximately 79.3°F, and wind was northerly. The group walked through the pond to the north of island 1 (Figure 2) and obtained the samples.

An experiment was done to determine the concentration of Allura Red in a commercially available beverage, Gatorade. This was done by using the colorimeter, the absorbance of five Allura Red solutions were measured. The graph obtained demonstrated a linear relationship and the equation obtained yielded a concentration of 1.9910-6M.

Cutting through the mink to study its anatomy helps the group to realize that they are similar to human. The most important tools used in the lab are scissor, probe, pins, tweezer, and scapula. The most tool being used is scapula which is used to cut up the mink and skin it. Safety materials are required in the lab in order to avoid accident. Since the minks contain cancerous chemicals on them, the classes are required to wear safety goggles, apron, and gloves. The class started the dissection from May 18th to May 27th in third period of Anatomy class.

Students have grouped together in their Anatomy Lab using three different types of Sucrose Bathing Solutions and three different deshelled chicken eggs. Students will learn the permeability of the cell membrane by studying the ability of a shell-less chicken egg to absorb the various sucrose bathing solutions. Students can see how membranes can regulate a cell’s interaction with its environment. The deshelled egg is semi-permeable, meaning that some molecules easily move across the cell membrane, some cannot. A cell membrane can transport materials through two general forms: Simple diffusion and Facilitated diffusion. Principles of Medical Physiology states “Facilitated diffusion, it is generally much faster than simple diffusion. Glucose and other large uncharged hydrophilic molecules have extremely slow rates of simple diffusion across the lipid bilayer but they cross the membrane much faster through facilitated diffusion.” Osmosis can be defined as the

In each passage that I read, "Energy Story", "Conducting Solutions", and the video "Hands on Science with squishy Circuits" there are many similarities and differences within the information I have gained in the articles and the video. The main idea of this video is to mainly inform you about electricity, the main principles of it, and some different ways to make electricity.

Students will be given books at appropriate reading levels for research to complete homework fact sheet.

Based on the data, the number of pill bugs on the dark side is higher at almost every minute compared the number of bugs on the light side. In the beginning, the pill bugs are evenly spread out on both sides. However, as time goes on, the number of pill bugs on the dark side increased rapidly, while the number on the light side decreases. Based on the graph, starting at about three minutes, the number of bugs on the dark side begins to increase significantly. The pill bugs quickly react and choose a best fit environment for themselves. Eventually, at nine minutes there are nine pill bugs on the dark side and only one on the light side. At the end of ten minutes, all ten of the bugs are on the dark side. If the experiment went on for a longer

To Kill a Mockingbird is a modern classic by Harper Lee that goes over the themes of prejudice, social inequality, family values, racism, conflict, and morality. The novel exposes people to the reality of racism and encourages them to confront and fight against discrimination for a just community. The story narrates the early years of Scout and Jem Finch while having their father defend a black man who had been accused of rape. Prejudice is a significant theme of “To Kill a Mockingbird” and is presented throughout the novel in many different forms. Prejudice is a destructive force in the town of Maycomb that ruins the lives of innocent people, solely due to the way they are perceived.

Table 1 on page 651 presents the population densities for a number of species. The statement is made “small organisms usually have higher population densities than larger organisms”. What are TWO different reasons why you might expect this to be true? (R)
