Transfer the peanut butter that is now on the knife to one slice of bread and spread the scoop of peanut butter evenly on this slice with the knife. If more peanut butter is desired repeat taking the peanut butter from the jar and spreading it on the same slice of bread. Put the knife down off to the side. Put down the slice of bread with the peanut butter on it back on the plate, next to the other slice of bread, with the peanut butter side up. The third step is to clean the knife using the napkin and wipe it clean.
6. Repeat step 5 four times. Data/Observations: Conclusion: Recall: We did a lab to learn about how the mass of an egg changes when it is put in different substances. Explain: We recorded the masses of two eggs every 15 minutes. One was put in water while the other was put in corn syrup.
Experiment & Observation I gathered together my items; distilled water, salt, ruler, scissors, stapler pencil, tape, 16 toothpicks, Kool-Aid drink mix strawberry and grape, set of McCormick food coloring red, yellow, green and blue, small bag of M&M candy, plastic beaker 50 mL, petri dish 60mm, well-plate 24, FDC blue dye #1 0.5 mL vial, FDC blue dye #2 0.5 mL vial FDC red dye #3 0.5 mL vial, FDC red dye #40 0.5 mL vial, FDC yellow dye #5 0.5 mL vial, FDC yellow dye #6 0.5 mL vial, unknown 0.5 mL vial, 3 filter paper chrom 14x7 cm. I first made a solvent using a 50 mL beaker with warm room temperature distilled water and a pinch of salt. I made sure the salt was completely dissolved and set the solvent aside. I took out two of the Chromatography filter paper sheets 14x7 and with a pencil very lightly drew a horizontal line 1 cm from the bottom of both sheet. Then horizontally on the line I just drew I marked off 9 spaces 1.5 cm apart.
Fill 1000 mL Beaker half way with distilled water, and then record the initial temperature of water. 2. Pick out a goldfish, and put it in the beaker. (Let it have a couple of minutes to settle into the new surrounding). 3.
2.Place all ingredients in a large bowl and mix well. 3.Pour the mixture in greased casserole dish. 4.Bake for 25 minutes.

Materials & Methods Materials: · Scale · 4 6” Dialysis Tubing · 4 Transfer Pipets · Sugar · Scissors · Rubber Bands · 4 Same-Sized Coffee Cups · 250ml Graduated Cylinder · Tape Measure · Sauce Pan · 3 600ml Containers · Plastic Covering · Spoon Methods: 1.) Place 4 6” pieces of dialysis tubing into coffee cups full of tap with and leave them for two hours prior to beginning the experiment. 2.) As you wait, prepare your three sugar solutions. For the first solution, pour 5 grams of sugar into 250ml graduated cylinder and add water up to the 250ml mark.
First I made a water bath by filling the 100 mL beaker with cool tap water. I then placed crushed ice in the 100 mL beaker so the water level was just below the top of the beaker. I sprinkled a little salt in the ice water and mixed it well. I then filled the test tube half full with distilled water and set the test tube in the 24 well plate. I inserted the digital thermometer into the test tube and took reading every 30 seconds until the readings remained constant.
To grow the E. coli, 190ml of 2% glucose nutrient media was added to a 250nl Erlenmeyer flask. 10ml of nutrient media was used to blank the spectrophotometer set at OD600. 10ml of E. coli stock culture were added to the 190ml nutrient media, creating a 1:20 dilution. The inoculated nutrient media was then placed into a 37C orbital shatter to incubate. All solutions measured with the spectrophotometer were placed in spectrophotometer tubes.
Take one pipette and fill each test tube with different amounts of Pb 4. Wait 20 minutes 5. Measure the height of the solid in each test tube.
Toast chile pods in the skillet for a few minutes, then remove to a bowl of water to soak for about 30 minutes. Preheat the oven to 450 degrees F (230 degrees C). Step 4. Place the tomatoes, 1 onion, jalapenos, and 4 cloves of garlic onto a baking sheet. Roast in the oven for about 20 minutes, until toasted but not burnt.
