eggshells. This steps was made by the researcher to make a chalk out of eggshells;First she clean the empty eggshell of the chicken through washing‚then when the eggshells is already dry‚ she pound the clean eggshells very well until it will become a powder‚then she get the residue and she separate it from the eggshell that is already in powder then she pour a liitle amount of water into the powdered eggshell and put it on the paper to form a stick chalk and she let it dry.

Experiment 3 Liquid-Liquid Extraction Discussion The success of extracting each compound out of the solution can be seen in the IR graphs for each substance. For ethyl 4-aminobenzoate‚ the N-H‚ C=O and C-O are distinguishable in their proper wavenumber positions. The amino N-H stretch was found between 3224 cm-1 and 3423 cm-1. The C=O was found at 1681 cm-1 and the C-O was at 1280 cm-1. The IR for benzoic acid also displays its significant bonds‚ O-H and C=O. The O-H was between 2566 and

Chapter I THE PROBLEM Introduction Rubber is an elastic hydrocarbon polymer which occurs as a milky emulsion (known as latex) in the sap of a number of plants but can also be produced synthetically. The major commercial source of the latex used to create rubber is the Para rubber tree‚ Hevea brasiliensis (Euphorbiaceae). This is largely because it responds to wounding by producing more latex. Other plants containing latex include figs‚ euphorbias and the common dandelion

pollution that makes our Environment damage so we decided to make funky colored sidewalk egg chalk as our science investigatory project. So based on our title name we will use eggshell not any eggshell because we will use chicken eggshell as an alternative ingredient for sidewalk chalk‚ we believe that this study will be great and popular because as of now children‚ students and teachers consume many of chalk which is expensive so we do this study and improve it for children who plays on sidewalk outside

‘The best teaching aid is a piece of chalk’ Discuss this point of view with reference to the alternatives. What are the best teaching aids? Every Teacher knows there is a place for chalk or white board pens in the classroom‚ every good teacher knows that chalk is not the only effective teaching aid in the classroom. There are three types of teaching in my opinion; regurgitating information word for word from text books and lesson plans‚ teaching using PowerPoints and so projecting‚ and finally

Part A: Diffusion on a liquid in a liquid. I did an experiment with three different glasses of tap water from the faucet. All three cups measured the same which happened to be 13 cm from the top of the cup to the bottom of the cup. I let the water settle‚ and sit for about an hour so the temperature was the same for all three cups. I then placed one drop of food coloring into the first glass and waited for the coloring to reach the bottom. I calculated 93 seconds. I then went to the second glass

Evaluation of Caucasian chalk circle The Intentions of the director was to shown how silly war was but put it into a funny and entailment way. There were to styles of acting were grotesque and naturalistic. The character Grusha gave the impression that she had lost everything her voice was weak but moving‚ her costume was rags which gave emotion of how much she has lost. The Nobel women used her voice to overpower other chat actors by her pitch of tone‚ she spoke to the poor as if they were rats
