GM Mom reports that Sarahia can walk up and down the stairs without supports from adults. Team observed Sarahia maintain her balance, intentionally throws a ball and ran 10 feet without falling. She is still working on kicking the ball, jumping without both feet together. FM When initiating play with clinician Sarahia extended toy and released it from her grasp with ease. Team also observe her using the pads of her fingertips to grab the crayon and was able to spontaneously scribble. PM

be no potato skin on each cube you cut out. You do not have to cut each cube to be exactly 1 cm2, but make sure they are very close to that measurement. Now label the cups with the sharpie and write down your group’s name and the concentration of solutions: 40%, 20%, 10%, 5%, & 0%. Measure the correct amounts of sugar and water into each of the labeled cups. One at a time, place a cup on the scale and add the sugar directly, but before you do so, hit the button “on” or “zero” to restart the scale.

This process relies on heating a solution to separate out the different components. This is done through the fact that each compound has a specific inherent boiling point, a temperature at which a liquid turns into a vapor. These vapors are then passed through a fractioning column. These

Prepared 2 tables in the lab notebook with solutes and 3 test solvents which are : acetonitrile, cyclohexane and water. One will be for the solubility prediction and another one for the actual data. Predict whether or not the solute will be soluble in the 3 solvents on the table. Compare the IMF in solute and solvent to predict solubility. If soluble write (S),slightly soluble(SS) and (I) for insoluble and which IMF will be the dominant one. Starting with water as the solvent.Obtain 8 test tubes

When performing the separation of a mixture, it is important to note the different physical and chemical properties of the individual substances in the mixture, such as polarity (polar and nonpolar) and solubility. Also important to take into consideration is the elemental composition and chemical makeup of the substances being manipulated. In this experiment, water and ethyl acetate are the two solvents given to be used to dissolve in the mixture. The water, being polar, will dissolve in other polar

The definition of solubility is a property of a solid, liquid, or gas solute to dissolve in a solid, liquid, or gas solvent. The two parts of a solution are the solvent and the solute. When a solute is dissolved, particles of the solute leave each other and become surrounded by particles of the solvent. In this lab, we tested stirring speed, concentration, particle size, and temperature and their effect on solubility. The question was, “How can you control the rate at which certain salts dissolve

solvent is the major part of solution which dissolves the solute, and solute is the part of solution that is being dissolved. Therefore the combination of solvent and solute is solution which is a type of homogenous mixture. For example, if water is the solvent and lemon juice and sugar are the solute, lemonade is the solution. Also, every solution has its own solubility which is the maximum amount of solute that will dissolve in a solvent under certain condition. A solution can be saturated, unsaturated

this lab was to create four solutions of the same components and different concentration. I found the concentration in Molarity (mol/liter). I would dilute a solution to create new solutions, using the formula M1xV1=M2xV2 where M=molarity and V=volume. In this lab, there were four solutions, Solution A, Solution B, Solution C, and Solution D. The solute or substance that dissolves was sugar and the solvent or substance that the solute dissolves in was water. For Solution A, I weighed 3.42 g sugar

Abstract In this experiment, a spectrophotofluorometer Shimadzu RF-5301 was used to determine the concentration of unknown riboflavin with 5% v/v acetic acid of 10 ppm standard riboflavin solution. An external calibration was performed in using 5 standard known concentrations of riboflavin and plotting a calibration curve. The LOD and LOQ were 0.0622 mg/L and 21.3 mg/L respectively. The calibration curve enabled for the determination of the unknown (3013) concentration of riboflavin at 0.37416

For this experiment, my group had several leaves of spinach and hole punched 40 disks out of the spinach leaf. In order to avoid any bias results, we made sure to avoid hole punching any veins in the spinach. After that we filled 4 cups each with 100 milliliters of carbon water. Each cup would have a different amount of salinity, the first cup would be the control group which would have no salt in it. The second cup would have ¼ of a teaspoon of salt in it, the third cup would have ½ of a teaspoon
