I enjoyed doing the virtual lab. I treat water as an occupation so I understood how and what to add to treat the water. If you have a low (acidic) pH then you should add sodium hydroxide. If you have total coliforms‚ you should chlorinate before and after treatment. Often‚ we test houses for total coliforms and e. coli. If the bacteria is positive‚ then we chlorinate the well. After we make sure all the chlorine is throughout the house‚ we let it sit for 24 hours to disinfect the pipes and

Develop hypotheses predicting the effect of pyrite and coal on the acidity of water? a. Pyrite hypothesis = If pyrite is added to a beaker with 100mL of water‚ then it will reduce the pH over 48 hours. b. Coal hypothesis = It activated carbon is added

PEPPERED MOTH SIMULATION LAB SANTIAGO JACOME THE VICTORIA SCHOOL BIOLOGY SL Data and Analysis Life Cycle of the Peppered Moth: Because their light wings are peppered with small dark spots. Predators of the peppered moth are flycatchers‚ nuthatches and the European robin. Larvae feed on the leaves of birch‚ willow‚ and oak trees. They change into pupae (cocoons) for the winter. They are given the name of carbonaria when black spots are present. Impact of Pollution: Near the centre of Manchester

(VCL) Introduction / Generic Lab Introduction Virtual ChemLab is a collection of realistic simulations. There are two general chemistry laboratories‚ including quantum and inorganic. The purpose of the quantum laboratory is to allow students to explore and better understand the foundational experiments that led to the development of quantum mechanics. In general‚ the laboratory consists of an optics table where a source‚ sample‚ modifier‚ and detector combination can be placed to perform

Introduction Most cells in organisms that reproduce sexually are diploid. They have two sets of chromosomes and two complete sets of genes. Gametes are an exception. Gametes are the cells that combine during sexual reproduction. In animals‚ these cells are called sperm and eggs. Gametes are haploid cells with only one set of chromosomes. Meiosis
