All organisms must have adaptations to survive. The adaptations that organisms develop help them to survive in their environments and then are passed down through reproduction. The genes are passed to future generations and adaptations continue to occur over long periods of time. Nature Works tells us‚” animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.” There are three types of adaptations that can occur: morphological

Procedure For the first part of the lab we will be verifying case 3 as explained by professor. We will measure the mass of the metal cylinder using the digital balance. After measuring the mass we also gather the diameter and height using the vernier caliper to calculate its volume. Using the mass and volume‚ we calculated its density. Now a beaker was filled with water and the mass was measured. The cylinder we originally used will now be suspended in the beaker full of water and the change of

transect line was then placed down the beach; I used a measuring tape to find the middle of it. A throwing quadrat was placed at the bottom of the beach and 20 pebbles were picked from it at random by students. These pebbles were measured using vernier calipers and their sizes were recorded. The 20 pebbles roundness was examined and classified using a Powers Roundness Chart. All of this data was recorded. This process was also repeated on the middle and upper parts of the beach along the transect line

INTRODUCTION This lab experiment required students to learn and participate on the usage of a manual lathe machine in order to shape a given raw material into a given specified end product. The class was divided into groups of 4 students. Each group will be assigned to one manual lathe machine and given three pieces of cylinder shaped mild steel rod and a schematic diagram to. A lab technician will brief the students in the usage of the machine and the processes required to machine the specified

Workshop Safety Practices Any accident may happen in the workshop while dealing with metal‚ tools and machines mostly because of sharp metal edges and rotating parts of machines. The accident may cause a serious injury that can even be lethal. Therefore‚ to avoid the accidents‚ following are a few steps that we should follow during the work in workshop: There are rules and regulations provided to use every machine available in the workshop. We should strictly abide by them. Take help from manuals
