    Introduction In order for us to determine the density or weight of a given mud, we can use a mud balance. In our experiment a 4-scale metal mud balance was used. The mud balance is being made in a way that the fixed volume cup at one end of the beam is balanced by a fixed counter weight at the opposite end, with a sliding weight rider free to move along the graduated scale and calibrated to read directly the…

    ABSTRACT Rarely do colors appear alone. They are normally used in different combinations. Since the number of colors is very large, the number of color combinations is almost infinite. Consequently, it is difficult to investigate how people perceive and evaluate color constellations in various contexts. Color serves as a means of communication. E.g. On the streets and highways, a red traffic light tells drivers to stop, and a green light tells them to go. Color plays an important part in…

    Egg Lab Write-Up Abstract Eggs provide us with a good demonstration of diffusion of the solutes within cells. Materials include an egg, vinegar, corn syrup, distilled water, an electronic balance, a weighing boat, and a cup. The reader will find that the egg becomes smaller after being soaked in corn syrup and it becomes larger after being soaked in distilled water. This concludes that corn syrup has more solutes while the water has less solutes. Introduction When a cell is…

    The ability to see in color is unique to humans and some other primates. It is called trichromacy because the retina of the eye uses three types of light-activated pigments to generate color vision. The majority of non-primate mammals however are dichromats, their vision is based on only two types of photopigments. Therefore, whilst frequent among primates, the property of color vision is not widespread among mammals (Jacobs & Nathan, 2009). Although there has been extensive research into this field,…

    Abstract This quasi-experimental study has evaluated a hypothesis that states that the use of color in instructional strategies enhances high school students’ short-term memory recall of new material and long-term learning. This problem was researched because previous peer-reviewed studies have demonstrated a positive correlation between color and memory performance on all ages, except for high school students (i.e. 14 to 18 years old). Following this method, with the use of a pre-questionnaire, it can be stated that this hypothesis is…
