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?
Part I: Scenarios (select only one) Scenario 1 Christopher and Kate noticed that after a rainstorm some of the rocks in their yard appear to shrink. They wondered how the mass of the rocks changed when dissolved in water. To
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.
1. 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.
Introduction: Rocks are a natural substance composed of solid crystals of different minerals that have been fused together into a solid lump .1 They are so common and we see them especially along the river bed, along beaches, also when we visit historical places we notice that most of the castles and roads are made of rocks .If we look at the photos of these objects taken long time ago and compare them to how these objects look now we can notice that their appearances have changed .These changes occur when rocks are exposed to the processes such as wind, water, and biological activities .Chemical weathering is another process which may affect rocks and to understand how rocks are altered by chemical reactions can be answered through this
Will different gloves with different amounts of friction have an affect on the amount of times a football is caught? If more friction is used, the amount of passes caught will increase, and the amount of passes dropped will decrease when the catch rate is the function of the gloves being used. The independent variable of this experiment is the amount of friction of different gloves. The dependent variable will be the amount of times the football is caught after being thrown. The experimental control will be using no gloves to add friction, and measuring the amount of passes caught.
For Quarter 1 of the stem project, we learned about erosion and how the planet is affected by it. Some of the things that I learned about erosion is that During this Project, was weathering and how it affects erosion. Weathering is defined as a chemical or physical change in a rock or mineral. I also learned that Some of the things that affect weathering are from animals, rain and temperature changes. I was assigned to find pictures that represent erosion. These pictures of Erosion had to be shaped in the form of a triangle. I got to chose my own pictures and put a triangle within it. The main purpose for this project was to learn about Triangles. I learned how to find the sides of a right triangle using SOH CAH TOA. I also got to evaluate
TECHNICAL LITTERACY CET 4.113 MATERIAL TESTING EQUIPMENT HAND HELD SHEAR VANE AND SCALA PENETROMETER TECHNICAL REPORT BY JERICHO MASIGAN ID:2015000286 3/20 Hororata Road, Takapuna Auckland firstname.lastname@example.org April 20 2015 NZHIT(Assignments) P O Box 9296, Waikato Mail Centre Hamilton 3240 Dear Surette Re: Technical Report Enclosed is the technical report as requested on 19th March 2015 for the written assessment in the Technical Literacy course. I have chosen ‘material testing equipment’ as my topic hence the report is titled ‘Material Testing Equipment - Hand held shear vanes and scala penetrometer. The report outlines the hand held shear vane and scala penetrometer and their use in geotechnical investigations.
Abstract This report discusses the testing of the durability of the Ultra-Thin Lifestyle, Trojan, and Durex Condoms by putting ball bearings in each condom until it broke for 3 trial runs. They are commonly known as a rubber layer
First of all everything mostly goes through mechanical weathering which is the breakdown of into smaller pieces by physical means. One cause of mechanical weathering is Frost action which was explained in the second paragraph. In conclusion this is telling you that everything probably goes through mechanical
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
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
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
OBJECTIVE The objective of this experiment is to obtain the grading curve for both fine and coarse aggregate.
