There were a numerous amount of observations and patterns in the data throughout the candle lab. The hypothesis was if the amount of candles inside the jar increases by an increment of one, then the weight of water in the jar will increase as well. The hypothesis was proven to be true, since for every candle added there was about 33 grams of water more. Every time the jar was placed over the candles, there would always be bubbles around the rim, also as more candles were used, the jar became cloudier and the bottom of the jar became more charred. The bottom of the jar also got hot, and after the jar was taken off the candles there would be grey smoke. The flame got larger as more candles were added, and the smell remained constant.…

Sophmore Kelly Caudel said, “ I actualley enjoy doing the experiments in this class, because it gives us a chance to get away from the bookwork and lectures that Mr. Bell usually makes us endure.” It seemed as if the students in his class were showing tremendous progress in their efforts at their lab stations. That is, until one pair of students dropped their Erlenmyer flask that contained what was left of the chemical compound that was being created. A minute after the very noisy shatter of the glass, the whole class turned to see what had happened. While the two students very awkwardly cleaned up their mess, Mr. Bell procceeded in his efforts to help his students produce what would be a lovely pinkish-looking fluid, which was the result appropriate for the lab conducted.…
Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components.…
(3) Using a vacuum filtration, filter the solution into a clean, dry Erlenmeyer flask with a side arm.…
This experiment could have been improved in many ways. For one, the process of submersing the top of the graduated cylinder in water without getting air bubble inside of the graduated cylinder could have been performed in a smoother fashion. Also, the process of lighting the butane lighter could have been better if the person lighting the lighter stopped at a more exact position instead of an approximate location. Another way the experiment could have been improved is if the person holding the graduated cylinder held it away from their selves to avoid…
Placing a mentos candy in a bottle of diet coke will cause bubbles to react. Bubbles are formed and it pushes the liquid up and out of the bottle causing an eruption. I became interested in this topic because my friend helped me choose this topic.…
I believe Atkinson County Middle School should go on a tour of Lava Beds National Monument! This interesting and beautiful landscape would be a remarkable vicinity for students to travel. Lava Beds National Monument is a breathtaking site that all undergraduate students should be able to experience in person.…
Purpose: To find out the unknown compound from known compounds and the color of the flame.…
This easy to make lava lamp is very cheap to make and is much better than going out and purchasing an expensive one. This lava lamp can be used if you’re trying to sleep and need a little light or is a fun activity you can show to kids or your own kids.…
Aim: To perform an experiment in the labs to determine the heats of combustion of selected alcohols and then to use this information and the gathered data from chemical data sources to determine trends in the longer chain alcohols. The Variables that MUST be controlled throughout the experiment are:…
Waterproof headphones and music player, tub of water(25°C), electrodes, computer, BIOPAC system, skin temperature sensor, ECG sensor, breathing rate sensor, thermometer, TI-84 calculator.…
Students will understand density, chemical reactions and simple circuits by creating a nifty take home, reusable lava lamp.…
Introduction I. Cinder Cone Volcano 1) What is Cinder Cone Volcano? A. How they erupt.…
How does lava temperature impact viscosity and velocity? The higher the temperature the lower the viscosity which allows it to develop a smooth surface skin, but this is quickly broken up by flow of molten lava, it creates a rough, clinkery surface. The lower the temperature of the magma the higher the viscosity which allows the lava to travel down the slope. In the group the average velocity was 0.91 cm/s . How the “lava” flowed was in a high viscosity and a low velocity because the “lava” was cold.…
