Matthew Mannetta Simple Harmonic Motion Lab Report Introduction Simple harmonic motion is the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke’s Law. In this lab‚ we will observe simple harmonic motion by studying masses on springs. In the first part of this lab‚ you will determine the period‚ T‚ of the spring by observing one sliding mass that is attached to two springs with the spring constant k‚ and attached to a hanging mass by a string

Simple Harmonic Motion Lab Report In this lab‚ I will study the principles of simple harmonic motion using an oscillating pendulum. If I were to design an experiment that would help me study the properties of an oscillating pendulum and investigate what causes a pendulum to swing faster or slower‚ I would prepare several masses (e.g. 20g‚ 50g‚ 100g‚ 200g‚ etc.) that can be attached to a string‚ several strings of varying lengths from 0.1m to 1.0m that are strong enough to support the weight of the

LabMr.P/Pd. 63/17/14 Osmosis and Diffusion Lab Osmosis is a process where molecules pass through a semi permeable membrane from a less concentrated solution into a more concentrated one‚ equalizing the concentrations on each side of the membrane. Diffusion is the spreading of something more widely.During the osmosis and diffusion lab I tested what happens to a fresh egg when osmosis and diffusion across membranes. The eggs were placed in vinegar‚ distilled water‚ and then lastly syrup. The

Examining Diffusion and Osmosis Introduction: Purpose: 1. To simulate and observe the diffusion of solutes and the osmosis of water through a semipermeable membrane through color change and sugar tests. 2. To speculate osmosis occurring in dialysis bags and potato cores by comparing percentage change in masses. Background information: Molecules are always in random‚ constant movement due to their kinetic energy. This causes the molecules of a cell to move around and bump into each other

everyday life. Diffusion and osmosis are processes that are a constant in our lives‚ even though many don’t realize it. Medicaments such as Fervex can be drunk only after diffusion has taken place and the powder granules have diffused into the hot cup of water. On the other hand‚ every day we become unintentional witnesses of osmosis when the roots of the plants try to suck up the water from the soil (1). The purpose of this lab is to show clearly in an understandable way how diffusion and osmosis happen

Cell Size: Is Bigger Better? Problem: Why are cells small? Objective: To see the relationship between cell size and diffusion of materials. Hypothesis: If we cut three different sizes of cells‚ then the smallest one will survive the longest due to its sufficient permeable membrane.

Diffusion and Osmosis Experiment Methods/Materials: 7.1 Experiment: Rate of Diffusion of Solutes In the initial set up of this experiment I had 2 sets of 3 screw-cap test tubes that had each been half-filled with 5% gelatin and 1-mL of the correct dye (either potassium dichromate‚ aniline blue‚ or Janus green) in each of the test tubes. I labeled the 3 test tubes of set 1 with which die they contained and marked them “5 ˚C”. Then with the other set I did the same exact thing‚ except I labeled
