Aim To measure how different concentrations of mythelin blue affects the rate of diffusion through agar jelly. Hypothesis The diffusion of mythelin blue is directly proportional to its concentration‚ hence as the concentration increases; the rate of diffusion increases too. Controlled Variables Time time was kept constant while testing the diffusion spread of mythelin blue with each concentration. Temperature the experiment was undertaken in room temperature as change in temperature can

The Spur Gear Prepared by: Henry L. Paz Objectives: • • • • To describe the spur gear; To identify the spur gear parts; To draw spur gear; To follow faithfully the steps in drawing a spur gear. Gear up and get ready to learn! Let me ask you. • What is a gear? Gear is… • Toothed wheel used to transmit power and rotating motion from one machine part to another. Gear is… • The simplest form of toothed wheel used in machinery with radial teeth parallel to the axis. Types

the summer. I would show up every morning while the dew was still clinging to the blades of grass at Blythe Park. I would arrive an hour before everyone else to prepare the circles of safety and to collect tinder that would litter the ground under the giant pines. The circle of safety was about a 2-foot diameter circle of bricks I would order from the Bothell Parks Department about one week before camp started. This fire pit itself was made on the site of the old brick building plant that was

In actuality there is a connection between everything in existence. Everything/everyone is connected to something/someone. One of my favorite examples of a system is the focus of the native culture. They use a circle to represent totality and view everything around them as part of their circle. A dominant theme in all Native American Cultures is that of relationship or a series of relationships that are always reaching further and further out. Relationships within the immediate family reaching out

around and around in a circular path. What do you notice about the lengths and directions of the blue and green vectors? Describe their behavior in detail below. When the ball is in a circular path the blue line points towards the middle of the circle‚ while the green follows the circumference. 4) Now move the ball at a slow constant speed across the screen. What do you notice now about the vectors? Explain why this happens. The blue line does not appear because when there is a constant speed

as sections of a cone standing on a circular base. The cone did not have to be a right cone‚ but could be slanted‚ or oblique. Apollonius noticed that all sections cut through such a cone parallel to its base were circles. He then extended the properties that he observed from these circles to ellipses and the other conic sections. He even solved the difficult problem of finding the shortest and longest distances from a given point to a conic section. These distances lie on lines called normals‚ which

A rectangle is a shape with four sides and four right angles. A square has four sides of the same length and four right angles. 2. What is an ellipse? (1.0 points) A circular geometric shape. 3. What is the difference between a circle and an oval? (1.0 points) A circle is perfectly round whereas an oval is not. 4. What is the difference between an arc and a segment when drawn with the Ellipse Tool? (1.0 points) An arc is a curved line. A segment is an arc‚ but closed from the center points of
