Extension Science-Construction Challenge Aim: To design and build a car out of recycled materials that can travel further than 5 meters determined with different front wheel sizes. Hypothesis: Using wheels that are light weight and made of plastic will allow our mousetrap car which is propelled by the force of the mousetrap being set off to travel further than 5 metres. Materials: • Mouse Trap • Screws • Washers • “r” clips • 2x Meccano wheels • 2x CD’s • Small white wheels • Small black wheels

paper‚ I will emphasize on advertisements in magazine and especially Mercedes cars ones. Mercedes cars advertisement’s differs from one magazine to another and this depends on three factors. The fist one is the type of magazine; the second is what the advertisers want to reflect as a message; and the third is to which public this magazine is addressed‚ but this doesn’t exclude the existence of some similarities. Mercedes cars advertisement’s differs from one magazine to another depending on which type

time graph of the toy car shows that the motion is non uniform. The car is not travelling at a constant velocity as the graph is not a straight line. A straight line graph would indicate that the motion is uniform as the position increase is constant throughout. However‚ the graph of the toy car is a curve that becomes steeper as the time increases. This suggests that the motion increases more and more as time passes‚ showing that the velocity is increased each second. As the car is also moving in the

The speed of chemical reactions – class experiment By Julia Shuker Year 10 science – Miss Phillips – Term 2 – 2013 – Julia Shuker Aim The aim of the experiment was to investigate the factors that increased or decreased the speed of chemical reactions between two different chemical reactions. Hypothesis If certain factors‚ such as concentration‚ temperature‚ catalyst and surface area are increased then the reaction rate will also increase due to the particles

Balloon Car Experiment Newton’s First Law of Motion states that when an object is set in motion‚ it will remain in motion until acted on by an outside force. Theoretically‚ this could mean you could travel at the same speed forever in one direction‚ right? The reason we don’t see this happen is because of friction. The force of friction is the resistance to motion that is in the opposite direction of the traveling object. This is why if you roll a ball on the ground it eventually stops. Friction

The Ideological Function of Cars A car is a personal tool for transportation that can be used whenever and for whatever reasons. Its role in everyday life varies across public and private spheres of society and carries with it various ideological assumptions. A car is understood to serve the basic universal purpose of travel in the modern world; however‚ it’s insertion‚ absorption‚ and appropriation into the ideological realm of society transforms cars into extensions of people’s relational identities

Samantha Mackey 13. 2nd hour PHYSICS LAB REPORT: SPEED OF SOUND Purpose: In this lab‚ we will be doing 3 major things: 1) Collecting and organizing data to obtain resonant points in a closed pipe‚ 2) measure the length of a closed-pipe resonator‚ and 3) analyze the data to determine the speed of sound. Procedure: 1. Fill the graduated cylinder nearly to the top with water‚ with a tall glass tube open at both ends (the water level with act as the closed end). 2. Determine
