It was very effective because the researcher has control over how much water is being squeezed out. * Rubber band- Used to secure the piece of paper towel to the glass bowl. This worked because a rubber band has stretching abilities when it comes to securing the paper towel. * An assistant- To assist with the

The purpose of this step was to remove (extract) most of the water that has dissolved in the ether layer. 2) The aqueous layer was drained and the solution discarded in the sink. 3) The ether layer was poured out the top of the separatory funnel into a clean, dry Erlenmeyer flask. 4) Several scoops of anhydrous Mg SO4 were added and the solution swirled. The MgSo4 absorbed the last traces of water the ether solution.
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.
In this project I studied a simple example of the latter type of instrument: a narrow-necked bottle partially filled with water. Hypothesis: If I filled up the bottle with water then the noise level will be low-pitched. Materials: To do this experiment you will need the following materials and equipment: · Several clean glass bottles with narrow necks · Tip: it is helpful to have several bottles with the same size and shape, plus
In the center the strips, about 3 cm from one end, place a dot of the marker to be tested. The dots should be about 0.2 cm in diameter and dark enough to be clearly visible. Place about 2 cm of water in each glass. Tape the unmarked end of each strip to the center of a pencil so that the strip hangs down when the pencil is held horizontally. Carefully insert the strips into the glasses, dotted end down.
2. Pour the tetracosane crystals onto a clean sheet of paper and crush them into a fine powder with the back of a spoon. 3. Place a small amount of the tetracosane crystals into the open end of a glass capillary tube, but be very careful to not break the thin tube--
Sit the child down and put on a pair of disposable gloves. Gently pull down the lower eyelid and any visible foreign body removed with either a clean wet piece of tissue or a small piece of wet gauze. If this doesn’t work, pull the upper eyelid over the lower lid and try to flush it out with tears. If the foreign body still remains in the eye try to wash the eye with clean water by positioning the child’s head over the sink or bowl with their eye open, facing the bottom of the sink or bowl. Using a plastic cup try to pour water on the eye from the tear duct outwards.
Transfer the distillate via Pasteur pipet into a 15-mL centrifuge tube. Wash the distillate with two 2.5-mL portions of water, removing and setting aside the water layer at each step. Transfer the organic material to a small, dry Erlenmeyer flask, leaving behind the last drops of the water layer. Remove any drops of water that were accidentally transferred to the Erlenmeyer flask, if any, then add small amounts of anhydrous sodium sulfate as drying reagent. When the liquid is dry, it will be transparent and some of the drying agent will flow freely like beach sand.
Dear Bob So you want to get salt from rock well all you have to do is. First you add some water to the rock salt (a mixture of sand mud and salt) Next warm and stir the mixture of rock salt and water for about 5 minutes. After Fold a filter paper in to quarters fit the cone of filter paper inside a funnel or something like a funnel. Once that’s done pour the rock salt and water mixture through the filter paper and allow the mixture to filtrate (to drip into the funnel only the pure salt dissolves) Take care when pouring that you don’t fill above about half way of the filter paper. The salt solution passes through the filter paper but the sand and dirt are trapped in the filter paper.
