G10 science By Freya Li Practical Investigation Resistance in Wire Aim: To investigate if the length of wire affects its resistance and find out how the resistance changes when the length of wire increases. Hypothesis: My prediction is that as the length of wire increases‚ the resistance will also increase. This is because current is the flow of electrons in a circuit and voltage makes the electrons flow through the circuit. The electrons have to collide with the atoms in the wire‚ which makes

Assignment 1: Using the Numeracy Core Curriculum Task 1 Identify some of the skills you could work on with Sally in order to develop her numeracy skills. You should include skills from each curriculum area (Numeracy‚ Measures Shape and Space and Handling Data). If you prefer‚ you may include a case study of your own; you will need to provide a profile of your case study and an explanation of the current skills levels and primary learning goals. Task 2 Complete the table below a) Using the progression

Formal Percent Composition Lab Report Percent Composition is the composition of space given as a percentage. This is the percent composition formula‚ that would help us solve our experiment. Percent composition is important because it shows how much a certain substance is comprised of one component or other Percent composition is used in our everyday life’s. For example if you want to measure how much sugar you have ate. Or how much calories have you gained. Or just how we did in our

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚

Wage Gap: The Other 23 Cents Imagine you and your co-worker – same position‚ same hours‚ same qualifications‚ same gender‚ and overall very similar – get your paychecks back and they got paid 1‚000 dollars while you get paid 770‚ 690‚ or even 550 dollars for the equal amount of work. That doesn’t seem fair now does it? Most of you probably would say no. So‚ let’s change it a little bit‚ same scenario‚ but this time you are either a minority sex or race compared to your white coworker‚ is that fair

Torque and Equilibrium Purpose: Apply principle of static equilibrium to determine a coefficient of friction. Research Question: What is the coefficient of friction between a meter stick and wall? Hypothesis: Tying a piece of string on to the end of a meter stick‚ put the other end of the meter stick against the wall so that the meter stick is horizontal and does not slide down the wall. Hang a weight on the meter stick sliding it to a point where the meter stick is about to come off from

Taha Al-Yousif Hooke’s Law Lab Date conducted: September 18th 2013 Partners: Mohammed‚ Liam‚ Ben Nguyen Purpose: The purpose of this experiment is to find the relationship between the stretch of the spring and the attached mass and to verify that this relationship is accurately described by Hook’s Law. Theory: Hooke’s Law states that to extend a spring by an amount (Stretch) from its previous position‚ one needs to add an external force (Mass). Therefore
