This study aimed to enhance students’ understanding in double-slit interference; especially the optical path difference. An alternative teaching tool called ‘Activity Sheet’ was developed and applied to the introductory physics class at Mahidol University in academic year 2016. The activity sheet contains a diagram of the double slit with two transparent strips. The sinusoidal wave pattern...
Nowadays, the techniques that use for cancer treatment such as chemotherapy and radiotherapy have deficiency and are not selective for killing only cancer cell. Cold atmospheric pressure plasma with dielectric barrier discharge (DBD) is one of the most important biomedical applications in cancer therapy. It can be applied to living cells and tissues and generated large amount of H2O2 and NOx...
This research was to study student teachers’ problem-solving skill after they learned through active learning activities in Introductory Physics I, the first semester of academic year 2017. There were 101 student teachers taking this course as a compulsory for 17 weeks. The research design was one-group pre-test and post-test design. Twelve active learning activities were developed by the...
In Particle Data Analysis lab activity, aimed at undergraduate and high school students, the student is tasked with classifying collision events which contain two muons decaying from J/$\psi$ meson. The activity provides 2000 collision events from CMS detector, selected by CMS Outreach community. However, classifying 2000 collision events by hand can be a tedious task for any human, so a...
This work analyses student understanding about propagation speed of the mechanical wave from different contexts using a model estimation of the model analysis technique. The modified version of the mechanical waves conceptual survey was administered to the first-year engineering (ENG, N = 644) and the second-year physics (PHYS, N = 37) university students. Corresponding contexts of the survey...
Kamnoetvidya Science Academy (KVIS) was founded by PTT to educate high-ability students to become future researchers and scientists, with a mission to cultivate creative thinking to drive future innovation. This is in line with the Thai Ministry of Education’s stated aim of developing students’ scientific inquiry and analytical thinking skills as part of the 4.0 goal to establish Thailand as a...
A portable and user-friendly tool was designed and built to measure pressure and temperature of the air with variable volumes. An Arduino board programmed to read pressure and temperature was installed in a closed container consisting of a syringe connected to a tightly sealed box. The volume of the air in the system can be altered by moving the piston. By considering the air as an ideal gas,...
Our group in the KVIS-ISB Student Research Collaboration Program investigated how the impact angle of a table tennis paddle affected the resulting spin of the ball. A table tennis ball struck a paddle at angles ranging from 10˚ to 80˚. Using high-speed video analysis, the angular velocity was measured for each impact angle. It was found that the sine of the impact angle was proportional to...
Learning achievement in fundamental electromagnetism performed by 110 engineering freshmen, enrolled in 2017 at King Mongkut’s University of Technology Thonburi (Ratchaburi), is presented. Activities for the class had not only been conducted by traditional lecture, but also with an integrated project assignment. Two key concepts in physics, the speed of an electromagnetic (EM) wave and the...
As part of the KVIS-ISB Student Research Collaboration Program, we collaborated on designing, conducting, and analyzing research into the formation of an impact cavity when a steel ball is dropped into a liquid. The relationships between the characteristics of impact cavity formation and the density of the liquid into which the ball is dropped were investigated. Densities ranging from 0.98...
Eggs are very good sources of low-cost and high quality protein. They are delicious and can be eaten well cooked, medium-cooked or raw. The objectives of this study were to define and determine the degree to which a hen's egg is cooked by boiling without breaking its shell. Assuming that an egg has a radial symmetry and a constant density, the moment of inertia is proportional to its mass...
As our part of the KVIS-ISB Student Research Collaboration Program we looked at how the drag force on cars driving in flooded streets depends on velocity and water depth. The relationship between the drag force acting on a car and the depth of the water that the car is driving through was investigated for a range of velocities. A model car was given a quick push along a track through water...
The ripple tank is a popular water wave phenomena demonstration tool for secondary school students. The projected wave images are observed in bright - dark patterns on a screen. This tool, however, falls short in presenting the amplitude of the waves which is another important parameter in explaining the wave phenomena. The free surface synthetic schlieren (FS-SS) method presents an immense...
The aim of this study was to fine the result of Problem Based Learning with an activity in the topic of “How can electricity cause the house fire?” The concept of this question was separated into 3 parts; short circuit cause the overload current, a large amount of current can cause high heat, and high heat over the Ignition Temperature makes the material on fire. There were 62, 7th grade...
The Colorado learning Attitudes about Science Survey, CLASS, has been used as a tool to measure respondents’ beliefs or attitudes about physics and how they learn physics. It is composed of 42 Likert scale (strongly disagree to strongly agree) type questions which is classified into 8 categories, which are real world connections, conceptual connections, personal interest, sense making, applied...
The red or blood-color Moon is the one characteristic of Lunar eclipse phenomena. This rare event occurs when the moon orbits into the Earth's shadow. In fact, the dust, ashes or gas in Earth’s atmosphere scatter the short wavelength of sunlight (blueish light). But they allow the longer wavelength (reddish light) travel through the atmosphere to space and reflect the Lunar surface back. Thus,...
Abstract: In this work, we develop a robust, and portable Arduino-based logic gate training kit. It was designed to use with an electronic engineering undergraduate university course instead of using fixed laboratory experimental apparatus. The training kit provides students with the necessary laboratory tool in order to learn a fundamental concept of logic gates operation regarding six logic...
A half-ring vortex near the free surface interface of water can be generated by dragging a half-submerged thin circular plate in the fluid and quickly pulling it out. This results in faster moving water in front of the plate rolling over the slower water next to the plate and creating a vortex. This vortex tends to preserve its momentum which results in the vortex continually spinning and...
A study of nucleate pool boiling phenomenon of distilled water on a copper heating surface with rotating blades installed above the heating surface was experimentally investigated. The rotating blades were made from Polylactic acid (PLA), with the number of blade of 4 blades, a diameter of 30 mm, a length of 50 mm, a blade angle of 90o, and a core of 5 mm. The study examined the effect of a...
This study examined the nucleate pool boiling heat transfer characteristics of distilled water at atmospheric pressure on a horizontal circular plate with rotating blades installed above a heating surface. The experiments were performed to explore the effects of number of blades as well as the visualization of pool boiling phenomena on nucleate boiling characteristics and the heat transfer...
