Eng 2116 Engineer Egg Drop Paper Description: Using only a single piece of cardboard, scissors and masking tape, construct an egg carton that will allow an egg to fall 20 feet without breaking. Idea: 1) Cut the poster board in to 2 halves. 2) Use one half to construct a cone. The cone should be large enough that the egg will fit into the open end of the cone but will go no farther than half way down the cone. (See figure 1.1.)
Add a bit of sugar to aluminum foil and fold the edges so it is covered from the sides. Record the physical properties of sugar. 2. Write a hypothesis on what you think will happen when heat is added. 3.
Paper chromatography can be used in separating amino acids and anions, RNA fingerprinting, and testing histamines and antibiotics. (Infromation received from sonic.org Purpose The purpose of this experiment was to separate the dyes that these markers are composed of and show how chromatography works. Materials * Four different markers (including one black permanent marker) * Rubbing alcohol or isopropyl alcohol * Coffee filters (2) * Tall glasses or plastic cups (2) * Pencil * Ruler * Tape * Table salt * Water * Measuring cups/spoons * Clean pitcher or 2-liter bottle Procedure 1. Your first task is to cut the coffee filter into a rectangle measuring three cm by nine cm. You will need 2 for this lab.
Experiment 8: Separation of a Mixture of Solids Purpose: The purpose of this lab is to separate the solids mixture containing the iron, sand, benzoic acid and salt. These solids were separated based on the unique properties of different solids such as variation in the magnetic properties and variation is solubility such as ranging from completely insoluble to completely soluble. Procedure: The necessary materials required for this lab procedures was obtained from the labpaq: solids mixture, weighing dish, and digital weighing scale. Each and every solid separated in this lab experiment was weighed using the weighing dish and digital weighing scale. From the solids mixture, the iron filling were separated by using the property of iron fillings that they were attracted towards the magnet.
On the Palette: Antique Gold Apply the Antique Gold diagonally, starting in the bottom left hand corner and take it to roughly 2/3 of the length, ending with a diagonal edge. With the Glaze moistened applicator, pick up a generous amount of Antique Gold and aggressively rub this color into the texture in a circular fashion, reversing and changing directions frequently to ensure the color gets into the lower areas of the texture.
Use the 1.0mm opening for 1.6mm fiber. Also trim the Kevlar to the ‘C’ length using the electrician style scissors. * Using the marker pen and the template card provided, measure and mark the buffer strip length as shown on the template. * Using the buffer strippers, strip off the buffer in at least two pieces. * Using a dry, lint-free wipe; Remove any remnants of the protective coating on the fiber after stripping the buffer.
To help you identify them, refer to the Mineral Identification Job Aid. * Borax * Calcite * Corundum * Graphite * Gypsum * Orthoclase feldspar * Pyrite * Quartz * Talc * Topaz 4.

Part 1: Recording Observations In the chart below, record your observations of each test for the seven minerals.
Method Part 1 1 Clean the surface of the 0.5cm piece of magnesium with a piece of steel wool 2 Place the magnesium into a test tube 3 Add three drops of detergent to the test tube 4 Add 2 cm of hydrochloric acid to the test tube. Set timer for 5 minutes and record your observations, including the height of the foam produced in a results table 5 Repeat the process for the
Place all of the shell in premassed breaker and dry the shell in the drying oven at 110 degree Celsius. for about 15 min. 2. Copy data and calculations tables from your teacher, as below. CaCO3 + 2HCl -----CaCl2 + CO2 + H2O ( Volume of acid added (L) ) (1.0mol/L) = moles acid added.
Angle of Incidence 0° 10° 20° 30° 40° 50° 60° Predicted angle of refraction 0 6.56° 13.0° 19.2° 25.02° 30.27° 34.74° Variables and Controls: Independent Variable: The angle of the light coming from the ray box or the angle of incidence Dependent Variable: The angle of refraction on the plexiglass. Controls: The mediums where light travels (air and plexiglass). Materials: - ray box - plexiglass - white paper, protractor and pencil Procedure: 1. I folded the blank paper into four equal parts. Then drew two intersecting lines perpendicular to each other.
