 * lab with zinc oxcide **
 * take 10 ml of water int o a test tube **
 * take a tiny bit of zinc oxcide in the textubetube **
 * the zinc oxcide sank to the botton **
 * stirr till compleetly disovved or tey to **
 * we made a mixture of zinc ocxcide it will not make a solution **
 * pour into a flask with a filter **
 * u can see the clear liquin~water is inside the flask zinc oxcide rests inside th e filter **
 * wash out test tube CARRFULLY **
 * it is foggyand wite when you stirrit and it looke slike salt or shugar in teh test tubeyou can see each and every little particle **
 * do the same thing as the the copper2 sulfide but see the results the water is slowly coming throufh because the zinc oxcide is cloging up the filter.The copper sulfate went through the filter because it is a solution. **
 * it **
 * momo ﻿movie notes **
 * the iron and sulfer ame a mixture when it was ignited it became brittle and stuck to thee rod that ignited it **
 * lab with copper 2 sulfate **
 * tale 10 ml of water and a timy scoop of copper2 sulfate shakit **
 * slowly and carefuly **
 * the copper sulfate is diaolving in the water it started ot become clear and the slowly started to turn blue the bluer it gets means the more consentrated it is transparent **
 * take both the copper2 sulfide and **
 * get a filter fold the filter twice put your finger beween the bottom two the filter will go into the funnel and you canto the fitler **
 * View our movie! **
 * [] **
 * l **** ab 4/12 **
 * take 10 ml of water in three beakers **
 * fold a piece of paper and fold it in half **
 * measure the paper oin a baleance that has been zeroed out **
 * thakl thwe pink substance(KOOL-AID) and then take a little scoop of it and put it on the paper verry carefully pour in it to the first test tube **
 * put the stopper in the top and shake **
 * record the appearance in your note book **
 * repeat this two more times, each time add an extra .5 gram of koolaide. **
 * Observations: **
 * When we added .5 gram of kool-aid to 10mL of water, the water durned red but was still trasparent. **
 * Each time we added an extra .5 gram of kool-aid to 10mL of water, the water turned a darker red and became less trasparent. **

Lab 4/18-4/19 we took some of this wight powder and put it in a test tube with water, and poured it in he same testtube wile we did that another person from our goruip filled a beaker with 200ml of water and set t on a hot plaet to heat the water when the water in the beaker was warm enough we set the test tube jently inside the hot water (REMBER!!! HOT ATER BURNS SO BE SHURE TO WEAR EYE PROTECTION) we ook the flat end of the little scooper and stirred the chemichal up ward inside the testtube to desolve it faster when it diso.ved we quickley put it in a beeker of cold wter(200ml) and carefully swirrled the testtube as we swirrled the testtube crystals becan to form in the testtube and the chemichal inside t became a solid



Lead nitrate and sodium iodine lab
 * First we add led nitrate and sodium iodine to two seprate test tubes
 * after we poured it in it turned a bright mustard colored yellow.
