PP+ Gas Laws vs PraxiLabs

The Gas Laws lab uses a syringe, masses, a thermometer, a hotplate, and a water and ice bath to investigate Boyle’s Law and Charles’s Law. It is part of Polyhedron Physics Plus, a set of 24 iPad apps for use in the classroom. To see how they work, try the FREE PP+ Newton’s 2nd Law lab. For those who’d prefer to develop their own experiments, the PP Gas Laws Apparatus app features a similar apparatus without lab procedures and other supporting materials. In addition to a 3D simulation that produces realistic data, each lab includes introductory videos, background theory, experimental procedure, analysis and reporting tools, pre-lab quiz, post-lab questions, and teacher support materials. The experimental data produced by the simulations are realistic, including random and systematic errors. These features allow students to use standard data analysis and error analysis techniques to report on their own unique data, just as if the experiment had been performed using hands-on equipment. These labs can serve as replacements for hands-on labs, especially when equipment is not available, or as supplements to hands-on labs. They are also a suitable option for students in distance learning and home school situations. Formative and summative evaluations showed no significant difference in learning between students using the virtual labs and those using hands-on labs. Preliminary results suggest increased learning by students using the virtual labs as supplements to hands-on. Polyhedron Physics was developed by Polyhedron Learning Media, Inc. with partial funding provided under contract numbers ED-07-CO-0040 and ED-IES-11-C-0029 from the Institute of Education Sciences in the U.S. Department of Education through the Small Business Innovation Research (SBIR) program.

PraxiLabs is a virtual laboratory that provides students with a safe and engaging environment to learn about science. Take your lab with you and use it anywhere and on any device. PraxiLabs is designed to cater to the needs of students, educators alike, the platform leverages the latest technology to provide access to different science experiments. Over 186 interactive experiments in different fields of science, Chemistry, Physics and Biology. The science experiments are conducted in a virtual lab, designed to simulate real-life laboratory environments, complete with state-of-the-art equipment, tools, and instruments. Allowing the students to perform experiments without the risk of accidents or damage to equipment. Real-time feedback on their experiments, helping the students to understand the concepts behind the experiments and to improve their results. PraxiLabs also features a variety of virtual experiments, which allow students to explore scientific concepts and principles in a hands-on and interactive way. Whether you're a student looking to enhance your understanding of science or an educator seeking to enrich your students’ learning experience and use an extra tool for getting the best out of your students, PraxiLabs, for sure has something to offer.
