You’ll need: a roll of Scotch Duct Tape, a utility knife, and a ruler. STEP ONE: Unroll your duct tape, leaving the sticky side up and measure and cut a 22-cm length. This is piece A. Cut a second 22 cm length (we’ll call this piece B) and lay it sticky side down, half way up piece A. Now, fold A over B.
There are about 9000 species of annelid known today. The ascaris are an intestinal worm, resembling earthworms in size and appearance. MATERIALS: * Dissecting pins * Gloves * Forceps * Lab apron * Scissors * Paper towel * Scalpel * Water * Dissecting probe * Preserved earthworm * Hand lens * Dissection tray PROCEDURE: We first put on our lab aprons, gloves, and (for the girls) make sure your hair is pulled back. We get the dissection tray and place the earthworm. Grab two dissecting pins and place them one on each end of the earthworm.
Check list: 1. foam hair roller 2. scissors 3. four yellow pipe cleaners 4. craft foam 5. one grey pipe cleaner 6. white styrofoam 7. black marker 8. white glue Backpack Zipper Bee Remove the hard plastic from the inside of the hair roller so that you’re just left with the foam part. 1 2 3 4 5 6 Now, wrap the yellow pipe cleaner just once around the bee’s body, leaving the rest of pipe cleaner free. Use scissors to cut out two small bee wings out of craft foam. Poke small holes at the end of each wing. Make a bee stinger by cutting about an inch of grey pipe cleaner, and poking it into the foam at the back end of the bee.
The first thing you do after you have blown your tire is to pull over to the side of the road, put the transmission into park and turn on your emergency flashers. Next is making sure you have a spare tire and the tools needed; for example; a lug nut wrench (or crossbar), to loosen the lug nuts (the hardware that holds the tire tight to the car) and a car jack. After you’ve located your tools, take your crossbar and loosen the lug nuts, turning counter clockwise, while leaving the tire on. You then place the car jack underneath the car and begin to raise the vehicle up until the tire is a couple inches off the ground. After you have raised the vehicle off of the ground, you then loosen the rest of the lug nuts and begin to take the tire off.
Once you have removed the cornea, place it on the board (or cutting surface) and cut it with your scalpel or razor. Listen. Hear the crunch? That’s the sound of the scalpel crunching through layers of clear tissue. The cow’s cornea has many layers to make it thick and strong.
2. Make crayon shavings by sharpening crayons with a crayon sharpener. Use different colored crayons. (These shavings will represent sediments.) You need enough crayon shavings of different colors to have a pile of “sediment” about 6 cm by 6 cm and 1 to 2 cm think.
If the driver doesn’t have a manual, just find the sturdiest point closes to the tire you are changing. With the jack in place, take the handle and turn the crank on the jack clock wise to start lifting the car up until the wheel is high enough off the ground to remove the tire. Once the car is off the ground, finish removing the lug nuts and place them in the hub cap. By placing the lug nuts in the hub cap, the driver will know exactly where they placed them. Remove the wheel from the vehicle placing it flat on the ground to
* 100% key lime * 50% key lime * 25% key lime 3. This is the formula to produce different key lime concentrations. * M1V1 = M2V2 Preparing of Kirby-Bauer test Materials and apparatus * Broth cultures of P. anvenginosa, E coli, S. aurens and B. spizizenii * Sterile cotton swab * Forceps * Bunsen burner * Whatman filter paper (small piece after punch) * Key lime discs * Parafilm Procedure 1. Swirl the contents of the broth culture of P. anvenginosa until it is equally murky throughout. 2.
Procedures: Gather up the following materials: 1 Blue cart, 1 wood plank, 1 stop watch and 1 meter stick. Next place the wooden plank on a hard cover book, so that is approximately 2.5 cm so that the way the plank extends onto the book. Important: Make sure that your checking the plank, it must remain in its position, because if you do the lab, the plank will move and its angle will change. Place the boxcar on the plank, and make sure that the center point of the car’s back wheel is on the top (back edge of the plank). And this will be the starting Point of each trial.
With both the right and the left laces still in hand take them and pull them across from each other forming the letter X. Then take either of the two laces and bring it underneath the opposing lace. Next, pull both laces until the tie is tight. Now that the base of the tie is finished, the hardest part has just begun. Making the two loops for the tie is the third step.
