Eggsellent Lab Analysis Questions 1. Draw and label two pictures - Initial and Final - showing the movement of food coloring molecules. You must use all of the following words: high concentration, low concentration, diffusion, and cell membrane 1. Draw the egg after it has been in the food coloring for 24 hours. Explain what might have occurred (be sure to explain what conditions had to exist both inside and outside the egg)using all of the following terms: diffusion, semi-permeable membrane, high concentration, low concentration.
Practical work I have used successfully includes: List the recipes and methods to follow (to build confidence and familiarity) Goal directed tasks (“ when you have prepared all your chicken like this you can have a ten minute break”!) Research and investigation tasks (such as compare prices and quality of a chosen piece of meat between supermarkets and butchers). Work towards the course
After the plane crashes, Brian knows he needs to make a shelter as soon as possible to protect himself from weather and large and dangerous animals. One of the first things he does is make a new shelter and he decides to builds his shelter against a rock wall “when he went in he found himself in a room about fifteen feet wide and eight to ten feet deep” (Paulsen 61). He also makes a bow to catch fish and fool birds. The first bow fails but soon “He had made a new bow, with slender limbs and a more fluid gentle pull” (Paulsen 118). With the working bow, he could catch and kill fish and birds to eat their meat and make feathered arrows.
Parasite Rex Questions 1. What did Anton Van Leeuwenhoek do to further parasite research? A: Anton van Leeuwenhoek put everything he could under his microscope, including the filth on his teeth, his meals, or even his own feces, to observe the little creatures that live inside these things. 2. What is the general rule for establishing similar species?
The purpose of this experiment is to test the hypothesis of pen’s ink affect on termite navigation. If this hypothesis is true, termites will follow a pen ink line only, regardless of the color of the pen’s ink. Method On January 13, 2014 three worker termites were taken out of the nest at the Coastal Carolina Community College Biology section and put into a petri dish with a damp paper towel. The initial observation (a termite following a red circle made of ink) was replicated again for a closer look. After obtaining 5 sheets of white computer paper (21.5cm by 28cm), Test 1 was performed.
Then, he had to associate the sound of the hopper with the presentation of a food pellet. I began this by consistently reinforcing him each time he was near the hopper. Once he found it, I reinforced him each time he took his head out of the food hopper. I began my experiment at 2:10 p.m. At first, Sniffy was a very curious rat. He thoroughly explored every corner of the operant box before making his way to the food hopper.
We represented the variation of beaks using tools such as pliers, tweezers, a staple remover, an ice cream scoop, a clothes pin and a baby spoon. Because all birds need the same type of food and nutrients to survive, competition occurred on these islands. In other words, the finches had to compete for
Hunting and its important lessons- Mostly they hunted birds. They stored the birds in sugar bags. They would roast the birds. They would come home with eight birds to have quite a feast. The ulimbo got into his eyes when he swinging the plastic bag around.
POW 13: Cutting The Pie The task in this problem of the week was to find out the maximum pieces of pie you could have with certain amounts of cuts. Specifically, I had to figure out how many pieces of pie there could be with four cuts, five cuts, and ten cuts, and to find a pattern that would assist me in finding the tenth cuts pieces. When we had an in class POW day was when me and my group started drawing pies and was when I got most of my work done on the problem. In the beginning, I drew out the pies with one cut, two cuts, and three cuts, and then started with the ones I had to figure out myself. The amount of pieces got bigger as I drew the pies over and over again because I figured out strategies to get more pieces.
Natural Selection Times By: Destini Shumate Date published: Feb. 26, 2013 Charles Darwin, a naturalist, has gone on a mission to the Galapagos Islands in search of fossils of extinct animals that look like modern animals. Darwin tells (Natural Selection Times) through webcam that he has noticed these birds with different shapes and sizes of beaks. He says that he has never seen that before but later realizes that they have different sized beaks for the different foods that the bird consumes. Darwin calls the birds Finches. Darwin states that he continues his voyage in the islands and notices the different shapes of the tortoises’ shells which allow different neck movements based on the environment.
