Mechanical Weathering Lab

The lab five B was about friction and how its always present. The purpose of this lab wat to explore how friction affect motion. There are three types of friction we discuss like air, rolling, and siding.

In site one there was a high proportion of very unspherical rocks. According to this the hypothesis is right, in site two there is a lot more smother rocks medium sized and in site 3 there are very small pebbles which are very smooth and spherical. The pebbles get smoother and rounder while it goes downstream. Due to us only taking about 10 rocks our result may have been not right as there were some pebbles which were largely over sized. Most of the other load is dissolved by solution such as limestone and chalk

Introduction In these experiments, the purpose was to recreate erosions over time with non-dangerous materials. In experiments one and two, the independent variable was the time. In experiment one, the dependent variable is the Na-24. In experiment two, the dependent variable was the pennies. In experiment one it can be seen that after every half-life the remaining amount of Na-24 progressively went down.

Equipment: 3 rubber stoppers, 5 rocks, wooden ball, wooden cube, 4 density cubes, triple beam balance, graduated cylinder, pipette, and beaker. 3. Procedure: 1. Create a 4 by 15 graph. 2.

- Get 5 50mL beakers and fill the first one with 30 mL of water

Rocks: Students learn about rocks through the use of a film. The student uses a white board to take notes, and organizes notes with the use of a graphic organizer.

Minerals are naturally occurring, inorganic, solid, crystalline substances which have a fixed structure and chemical composition. Minerals are an important part of Geology, especially when studying Crystal and mineral growth. Understanding how crystals grow and the difference between slow and fast cooling rates is also important in Geology. Knowing the difference between cooling rates is important because cooling rate changes the texture of rocks and minerals. The purpose for the Crystal Growth experiment is to identify which Solubility and temperature produces larger crystals, and to simulate natural crystal growth. We will achieve the results we desire by conducting the experiment thoroughly and correctly, as well as correctly

With volume and mass determined, the density formula (d = m/V) was used to determine the densities of each rock and recorded in g/ml.

During this A’STEAM activity, you will be conducting experiments at three different tables to determine the geological forces that create the many rocks within the three different types of rocks. You will start at one table and rotate to the other two when your counselor tells you to do so.

Rock Candy (also called rock sugar) is a type of confection composed of relatively large sugar crystals. This candy is formed by allowing a supersaturated solution of sugar and water to crystallize onto a surface suitable for crystal nucleation, such as a string, stick, or plain granulated sugar. Heating the water before adding the sugar allows more sugar to dissolve thus producing larger crystals. Crystals form after 6–7 days. Food coloring may be added to the mixture to produce colored candy.

We then weighed them to find our initial mass for our data. After all were measured, we put 100 mL of the six different solutions of sugar and water; 0.0 M, 0.2M, 0.4M, 0.6M, 0.8M, and 1.0M. We then covered them with paper and left them overnight for two days. Next class period we dumped out the solutions and weighed the potatoes to find our final mass. After, we threw out the potatoes and cleaned up. Data Observations and Data

pg:1 my theory is when the plates moved he seen that the same fossils were on the plates that they were on the wrong plates in the wrong weathering. Places this show that his theory was right because the fossils were in a place that they could die in because of many reasons from being cold and frozen and it could be hot in those is this pg i wanted to say that the fossils will die in the wrong weathering

Rock candy is a simple scientific experiment made at home from sugar and water. Rock candy can be made up of different types of sugar. I used pure cane granulated sugar. Rock candy is formed when sugar is dissolved in boiling water and is cooled and placed in a glass jar with the wooden skewer. When the water evaporates the sugar crystal will start to grow overtime. The water and sugar is a saturated solution, meaning that water could only hold sugar if both were very hot. By cooling the water, the sugar comes out of the solution and forms crystals on the skewer and around the glass. The hypothesis for my experiment was that the more sugar you use the more crystals will form. My question is if you add more sugar, will more crystals?

The objective of this experiment is to obtain the grading curve for both fine and coarse aggregate.

Experimental stress analysis is a method of stress and strain testing of materials, to test for behaviour changes of materials under fatigue. The first method of stress analysis used was the Strain Gauge invented by Edward E. Simmons and Arthur C. Ruge created in the late 1930s to test for earthquake stress on elevated water tanks[1]. The creation of lasers and interferometry methods in the 1960s provided the basics of digital image correlation where high-speed cameras could be used to capture behaviour changes in materials during deformation. As the years went on, advancements in imaging, laser and sound technology allowed for new innovative techniques to be used to measure strain and stress. Some of these techniques include are digitised ultrasound images, non-linear least squares and robust stereo-vision system[2].
