Wakeboarding Wakeboarding was invented by a San Diego surfer named Tony Finn. Tony began a wakeboard revolution in 1985 when he developed his cross between a water ski and a surfboard. Then‚ the owner of H.O. Sports‚ a leading water ski manufacturer took interest in advancing it by introducing the first compression-molded-neutral-buoyancy wakeboard. He called it the Hyperlite. This wakeboard led to the growth of the marketplace making wakeboards more accessible to everyone. How a Wakeboard Works

Calorimetry: Enthalpy of Neutralization Introduction: The purpose of this lab experiment was to determine the molar concentration of the unknown HCl by using a coffee cup calorimeter. A coffee cup calorimeter is made of Styrofoam cups with a thermometer that is placed from the top and into the calorimeter to measure the temperature as the reaction happens. The Styrofoam cup used for the calorimeter creates an isolated system as it acts as a heat insulator between the cup and the surrounding

Using Gibbs’ Reflective Cycle Gibbs’ Reflective Cycle (or Gibbs’ Reflective Model) Gibbs’ reflective cycle is a theoretical model often used by students as a framework in coursework assignments that require reflective writing. The model was created by Professor Graham Gibbs and appeared in Learning by Doing (1988). It looks like this: Action plan If it arose again what would you do? Descripiton What happened?

Joshua Berkebile 8-26-10 1st period Density Lab The purpose of this lab was to find the mass‚ the length‚ the width and the height of 4 different cubes so we could calculate the volume and density of them. We also had to find the density of irregular shapes by dropping them into a graduated cylinder than subtracting the starting water volume by the ending water volume. Density is how much mass is in a certain volume of matter. Volume is the amount of room that an object

Aim:To discover what factors affect the rate of diffusion of potassium permanganate crystals in water. Statement:What will happen? How will room temperate solutions or heated solutions increase the rate of diffusion of the potassium crystals?Hypothesis:Heat will speed up the process of diffusion because heat will give out energy that will be able to speed up the process of spreading the potassium molecules.

Forces What Is a Force? Forces represent the interaction of distinguishable objects. Specific forces: The weight W with magnitude W = m * g acts near Earth’s surface with g the gravitational acceleration. (m= mass) The normal force N is due to contact with a surface. It is directed perpendicular to the surface. The tension T is due to a taut‚ massless string. It is directed along the string. The external contact force Fext acts along the direction of the push. Unit: Force and force

Lesson 1.02 Speed‚ Velocity‚ and Acceleration Speed- measures the amount of distnace traveled in a given amount of time. (Doesn’t measure the direction of the travel) How fast an object is going with respect to a frame of reference. You find speed by dividing distance by time. (Speed = distance/time) Instantaneous speed- the speed you are traveling at that moment‚ instead of an average. Motion- change in position of an object‚ relative to a frame of reference. Frame of reference- place or object
