Experiment 4A: Determination of a Partition Coefficient for Benzoic Acid in Methylene Chloride and Water Experiment 4B: Solvent Extraction I: Acid-Base Extraction Using the System Benzoic Acid‚ Methylene Chloride‚ and Sodium Bicarbonate Solution Objective A: To accustom participants (students) to general procedures that are used to obtain a partition coefficient at the microscale level. We will gain experience in such practices as the transfer of microliter volumes of solutions with a Pasteur filter

How The Scientist Discover The Interior Of The Earth Two ways that Scientist may study and find the interior of the Earth are with Meteorites and Magnetic Fields. The scientist may use meteorites to discover the interior of the Earth’s earlier solar system by studying the meteorites that arrived on the Earth. The scientist might use magnetic fields by the science advances which involves measuring the ocean and coming up with a hypothesis. Therefore‚ the meteorites and the magnetic fields all

similar number of fish observed. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. If the amount of dissolved oxygen is increased‚ then the number of fish observed will increase. 3. What would your experimental approach be to test this hypothesis? For my experimental approach to test this hypothesis would be very simplistic. I would replicate the experiment and use different amounts of dissolved

EYMP 2 task 4.3 Use language that is accurate and appropriate in order to support and extend children’s learning when undertaking activities. Language is crucial to young children’s development; it is the essential key for learning‚ for communicating and building relationships with others as well as for enabling children to make sense of the world around them. My role in developing and encouraging language acquisition in children is therefore of the utmost importance. Children learn most effectively
