Science Lab on Electromagnets By Caitlin Hendriks Factors that Affect the Strength of an Electromagnet Purpose: To test how two different factors‚ the number of loops and the current intensity‚ affect the strength of the magnetic field of an electromagnet. Materials: Power pack‚ 4 connecting wires‚ switch‚ ammeter‚ paperclips‚ iron nail‚ copper wire. PART A: TESTING THE NUMBER OF LOOPS Procedure: 1. Create an

● Water ● Ice ● Water baths ● Vials ● Marking Pencils ● Stopwatch Procedure 1. Set up an ice bath (0°C)‚ a room temp water bath‚ a 37°C bath and a boiling water bath 2. Place 5 ml of catalase at 100 units/ml in each 4 test tubes. Place 1 test tube in each of the water baths 3. Place 40 ml 1% H2O2 in each 4 vials. Measure and record the depth of the H2O2.Place 1 vial in the 0°C bath and leave 3 at room temperature. This is necessary because heat will destroy the hydrogen peroxide. 4

plate height is calculated using the equation: H = L/N Plate height is normally reported in millimetres. The ability of a column to separate components of a mixture is improved by decreasing the plate height‚ so therefore an efficient column will have more theoretical plates with smaller plate heights than an inefficient column with less theoretical

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

and Simple 1D Collisions PhET Lab Introduction: When objects move‚ they have momentum. Momentum‚ p‚ is simply the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum‚ p‚ is kgm/s. During a collision‚ an object’s momentum can be transferred to impulse‚ which is the product of force (N) and time (s) over which the force acts. This allows us to write the momentum-impulse theorem: Procedure: Play with the Sims Physics Motion Collision Lab Work with 1D collisions at

Experiment 3: ANALYSIS OF UNKNOWN ACID SAMPLE USING TITRATION METHOD Date of Experiment: 4 September 2012 Introduction An acid-base titration is a procedure used in quantitative chemical analysis to determine the concentration of either an acid or a base. Titration is the slow addition of an acid (or a base) of known concentration from a burette (a narrow graduated cylinder) to a base (or an acid) of unknown concentration fin an Erlenmeyer
