Acid-Base Reactions: DIY Lava Lamp
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 [...]
Germs on a Loofah
A while back, we did an article on the kitchen sponge, and all the germs that could be lurking in there. If a kitchen sponge is a perfect place for microbes to make a home, [...]
Water Hardness Science Experiment
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 [...]
Fall Into Science: Leaf Chromatography Activity
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 [...]
Drinking Water Science Experiment
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 [...]
Tech Talk with Sensonics: New PTC Studies
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 [...]
Test Strip Vial Rocket
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 [...]
Neutral pH: Does Water Have a Taste?
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, [...]
What Role Does Yeast Play in Bread-Making?
Fact: we love food, and we love science. So, when the two come together, we get excited. Making bread is actually a very scientific adventure because it involves microbiology and chemistry, and much of that [...]
Microbe Cafeteria: What Microbes Have You Been Eating?
How does the saying go? You are what you eat. Well, microbes are everywhere, in everything, so we know it’s in our food. And we know from our article, Microbes and You: We’re All Just [...]
Diffusion and Osmosis Experiment
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 [...]
Misuse of Potassium Iodide Starch and Chlorine Test Papers
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 [...]
