Material Detail

This is a great virtual lab space at a time when universities are shutting down chemistry lab classes. Ample information on the chemical equation(s) involved in a given experiment is provided and modules are an open-ended in design designed (i.e., “Design and perform an experiment to determine the ….”) and auto graded. Although virtual labs are not justifiable substitutes for the real thing, the animation in each module come close enough to experience these lab experiments.

Always i want it, because is more easy to learn chemical with interactive material. Thank you for this material.

This resource did an excellent job of providing a virtual workspace for my general chemistry students during the covid-19 lockdown. Students used the virtual "Creating a Buffer Solution" lab space as a backdrop for completing a buffer design lab that would usually be done at the bench, and were enthusiastic about the animation, the ease of use of the applet, and their ability to try experiments multiple times without penalty. I will continue to use this resource when classes meet face-to-face again! I do recommend that students begin with the introductory video.

Here studnets will have chance to mix chemicals without wearing safety goggles. They won't spill any acid on the spectrometer in this lab.They will choose solutions from the vast database and mix 'em together till the cloned cows come home. Marvel as the chemical solutions react in real time

Although it took me a while to figure it out, this one will definitely be recommended for the course I'm helping to develop.

Remarkable simulation of a chemistry laboratory. You can use virtual solutions and get the same results that a real laboratory. Presents information of molarity, ph meter and component of the solutions.

I will definitely use this in the future with my teacher candidates. Excellent tool for schools that don't have a lot of equipment and chemicals.

I think this could be a good lab for instructors and their students to use before the actual lab day. There does seem to be a bit of a learning curve with doing this, so I'd make sure to tell students to view the tutorial AND to take notes.

Technical Remarks:

SAMPLE: As a student, I always found labs boring because it was just following the same directions. WIth Virtual Chem Lab, I was able to test ideas on my own without running out of time or worrying about making mistakes.

very good material

This is an awesome site. I am in the Education Program right now and I would love this and I'm going to send my sister here.

Technical Remarks:

1. How did you review the materials? (Did you spend 5 minutes browsing or 2 hours trying it?) Spent about 30 minutes browsing site and performed simple titration lab using HCL and NaOH with Phenolphthalein as indicator (using Buret). 2. The quality of content. (Do the materials accurately present concepts and models that are educationally significant?) The handling of the lab equipment is straight forward and the array of reagents (mostly acids and bases and indicators) provide for the development of a variety of labs on acids, bases, neutralization, indicators, conjugate bases & acids, as well as possible experiments on dilution of acids & bases, and formation of precipitates. Also, the presence of the thermometer and Log of the different ions provides a good tool to teach exothermic reactions between acids and bases as well as the time course of the changes of various ions during the chemical reaction process. I think a brief tutorial is necessary to have students get accustomed to the workshop, using the mouse to gather and handle equipment and reagents, as well as become familiar with the lab bench and pH meter and other log based read outs. 3. The potential effectiveness for enhancing teaching and learning. (If used appropriately, will students learning and faculty's teaching be enhanced?) If used properly, this lab would be very useful in understanding the various lab techniques as well as principles of pH scale and neutralization. I would highly recommend it for online courses or as a practice run prior to having students actually use acids and bases in a real laboratory setting. If properly used as a lab simulator, it could reduce the risks of lab accidents with acids and bases in real laboratory situations. 4. Technical Remarks: Specifically address the following issue: 5. The ease of using the materials. (Will first time users fine it easy to use?) Students will need to have Java applet plug-in present. Before students go to this site, it is suggested that they be referred to www.java.com; test if the have Java, and download the plug-in if they do not. Also, it helps if this is an online course to notify the Tech Help Desk that they may need to assist newer students in downloading the Java plug-in. But, it is STRONGLY urged that any course using this site have a technology requirement (listed in the syllabus) that the student computer already have Java plug-in present. I think a brief tutorial is necessary to have students get accustomed to the workshop, using the mouse to gather and handle equipment and reagents, as well as become familiar with the lab bench and pH meter, temperature, and other log based read outs of ions and presence of gases and solids (e.g. precipitate). One suggestion is a demonstration and then a test lab where student just manipulate the stock bottles to make dilutions of acids and bases (both weak and strong) and read the resultant changes in pH. Also, one other training exercise is to have students fill a beaker from a stock container to get used to the “select as source” and “select as recipient” settings.

Technical Remarks:

This Virtual Chemistry Laboratory idea is AMAZING! I love it! In our school district we do not have the funding to allow for labs in our grade schools! What a great way to give our young students a head start!!! Thanks!
