On Thursday‚ September‚ 28 in Ms. O’Brien’s Honors Science class we conducted two experiments the Mixed Substances Lab and the Investigating Mixtures Lab. The objective of the Investigating Mixtures Lab was “To observe that not all liquids behave the same way when mixed with other liquids”. Before we started the lab we we each created a hypothesis mine was “If the water and vegetable oil are mixed and the two combine and make a mixture‚ then the vegetable oil will float and the water will sink”.

Investigating the resistance of a wire. Planning For this investigation there are a number of variables that can be chosen to change or keep the same‚ these are: · Length of the wire. · Diameter of the wire. · Type of the wire. · Temperature of the wire. Scientific explanation. All electrical conductors resist current through them to some extent. This is resistance and this affects the size of the current flow. The main dependence of resistance are: § It’s Length. § It’s Thickness

Introduction We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid. I will add calcium carbonate (marble chips) to hydrochloric acid. When calcium carbonate is added to hydrochloric acid a reaction takes place. The solution fizzes and gives off the gas carbon dioxide. I will collect this gas in a gas syringe and will time how long it takes for the reaction to produce 100cm3 of carbon dioxide. CaCO3 +2HCL Co2 +CaCl2 +H2O CalciumHydrochloricCarbonCalciumWater

Another postulate of the kinetic molecular theory is that gas particles are always in motion‚ like the other states of matter. But they are different in that they undergo random translational movement. In solids‚ the particles mainly experience vibrational motion and in liquids they mainly vibrate and rotate‚ with some translational motion. Gas particles move rapidly in straight lines‚ unless acted upon by another particle or the walls of a container. This continuous contact with the container leads

Natalie Drossoyianni I.B 1 Psychology HL Discuss the use of technology in investigating cognitive processes. Technology has been very useful for the past few years in investigating cognitive process. With the use of neuro-imaging techniques‚ researchers can examine brain structure and function‚ and thus understand better the relationship between cognition and physiology. The basic neuro-imaging techniques are the PET‚ the MRI‚ and THE fMRI scan. The PET or else the positron emission tomography

My Reaction Paper This is my reaction paper on a movie that I watched entitled “The Wizards Of Waverly Place: The Movie”. Wizards of Waverly Place: The Movie follows the Russo family as they embark on a vacation to the Caribbean resort where Jerry and Theresa first met. Alex‚ upset that she was forced to accompany her family on the trip‚ conjures a spell that erases her parents’ fateful first meeting and puts the Russo family’s very existence in peril. In order to reverse the spell‚ Alex
