The EPA (U.S. Environmental Protection Agency) is a great educational resource that not everyone is aware of, so we like to share some of their experiments and informative web pages whenever possible. They have some [...]
We love a good acid-base reaction and pretty much anything to do with the pH scale, so today, rather than using our test strips, we’re just doing a fun acid-base activity! Lava lamps might be [...]
Here at Precision Laboratories, we live in a region with very hard water. Water softeners are common place, and without them, calcium deposits can quickly build. But not every place is like this. In the [...]
With the fall season now in full swing, we thought it would be fun to do a fall-related science activity: leaf chromatography! As we explained in our previous post, Easy Chromatography Paper Experiment, we do [...]
We work with a few companies that are making devices to help bring safe drinking water to low-resource communities where it is otherwise hard to come by. We mentioned Cascade Designs in an article posted [...]
Our PTC taste test papers have been used for years in genetic studies to identify individuals who can taste the bitter substance versus those who cannot. The simplest form of this test is to classify [...]
Before the weather turns to snow and cold, we thought we’d find a way to enjoy the beautiful fall weather while we still can. This is different from our usual science experiments because it also [...]
When you look at any example of the pH scale, you see that water has a neutral pH of 7. You’ll also see example of acidic substances, like lemon juice, orange juice, and tomato juice, [...]
Our Glucose test strips can be used in biology classrooms to perform diffusion and osmosis experiments. Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration, continuing [...]
Our Potassium Iodide Starch test paper detects available iodine, chlorine and peroxides in solution. Lower levels react with the strip at 5 – 10 ppm. Iodine requires approximately 60 seconds to react, and initial reactions [...]
