Rotational rubbing of left thumb clasped in right palm and vice versa 8. Rotational rubbing, backwards and forwards with clasped fingers of right hand in left palm and vice versa 9. Rinse hands with water 10. Dry thoroughly with single use towel 11. Use towel off faucet Instructions for proper diaper-changing technique 1.
10. Repeat the entire procedure with the four other eggs. Plot the densities for all five eggs on a chart. How much variation in density is there from egg to egg? Background Research- How Salty Does the Sea Have to Be for an Egg to Float?
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.
September17.2013 P.4 Environmental Sources Of Bacteria Purpose: We did this lab to find out exactly which conditions would help to grow a bacterium the best. Materials: • Agar • Petri dish • Cotton • Incubator • Tape • Bacteria Procedure: 1. Mark bottom of Petri dish 2. Split petri dish into 4 sections and label the sections 3. Pour hot agar into dish 4.
Purpose The purpose of this experiment is to see the effect that paper chromatography has on ink. 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. Coffee filters usually are round, but it's easier to compare your results if the paper is rectangle. So, your first task is to cut the coffee filter into a rectangle measuring three cm by nine cm. You will need two of these strips to complete the lab.
To determine if hyphae grow at the same rate, graph the results of table 2 and compare the slopes of the 3 hyphae from the slide preparations. 11. To determine if mycalolide B affects fungal tip growth and nuclear position repeat all the steps except in step 2 need to add mycalolide B and let it incubate for 10 minutes. Make sure to label the slides with the
Then horizontally on the line I just drew I marked off 9 spaces 1.5 cm apart. On one sheet inside the spaces I marked B1, then B2 in the next space and so on for the FD&C food color dyes, at the end I marked KS and KG for Kool-Aid strawberry and grape. On the second sheet of Chromatography filter pater I did the same thing. I made a 1 cm line from the bottom and spaced it off in 1.5 cm spaces. I marked those with the Store Food Colors, the M&M colors and the unknown color.
Physical Science Penny Lab Purpose The purpose of this lab is to see how the placement of the drops of green solution will affect how much the penny can hold up the green solution without dropping any solution on the table. Hypothesis I think that when we drop the green solution on the middle of the penny, the penny will be able to support more green solution because the green solution will have more room to spread out. Materials -25ml of mysterious green solution -Paper towel -A 150ml beaker -A penny -A pipette -A ruler Procedure 1) Place 25ml of the green mysterious solution into the beaker. 2) Squeeze the pipette in to the solution for three seconds and let go. 3) Place the penny tails up 4) Place the pipette over the letter “c” in “one cent” 5) Place the pipette 5 inches above the penny 6) Begin to slowly squeeze the solution out of the pipette, over the letter “c” while counting the numbers of drops until the solution spills out from the surface of the penny.
The Fitzwilliam cup-and-stand set has a stronger blue tint in its glaze color and is not as flawless as the Injong tomb pieces, but it clearly demonstrates a comparable dedication to craftsmanship. The stand has a petal-shaped, extended rim, dome-like cup pedestal and a high flared foot. It is decorated with a celadon glaze pooling bright green where the lines recede and spur marks on the inside of the foot. [pic] Wine ewe Goryeo dynasty (918–1392) Early 12th Century Korea Stoneware with celadon glaze over mishima decoration of geese, waterbirds, and reeds, uses the
You may spool the DNA on your glass rod or pipette tip. 10. Spool the DNA by dipping a pipette tip or glass right where the extract layer and alcohol are in contact with each other. With your tube at eye level, twirl the rod and watch as DNA strands collect.
