Welcome to the world of lab equipment! This guide introduces essential tools you'll use in your physical science... Show more
Every scientist needs to know their glassware! Graduated cylinders give you precise liquid measurements, while Erlenmeyer flasks are great for heating liquids but less precise for measuring. Beakers are versatile containers for holding, mixing, and heating both liquids and some solids.
Test tubes are perfect for small chemical reactions and holding small amounts of liquid. You'll use a test tube rack to keep multiple tubes organized and a test tube holder when heating tubes to avoid burns. Test tube stoppers create tight seals, often used when collecting gases during reactions.
Test tube clamps secure tubes to ring stands during experiments, keeping your setup stable and safe.
Safety First! Always check glassware for cracks before using. Even tiny cracks can cause dangerous breaks when heating or holding chemicals.
Glass stir rods let you mix chemicals without contamination, while watch glasses serve as lids to prevent splattering during reactions.
When it comes to heating, you have options. Hot plates use electricity to heat chemicals safely with temperature control. Bunsen burners provide gas-powered flames for more intense heating, and you'll use a striker to light them safely (never use matches!).
Your heating setup requires proper support. A ring stand holds equipment above heat sources, while iron rings support specific apparatus like clay triangles or crucibles. Wire gauze placed between glassware and flame helps protect equipment and diffuses heat evenly.
Lab Hack When using a Bunsen burner, a blue flame is hotter than an orange/yellow flame. Adjust the air intake to get the right temperature for your experiment.
Moving substances around the lab requires special tools. Funnels help pour liquids from larger to smaller containers without spills, while filter paper separates solids from liquids during filtration.
Hot equipment needs special handling. Use beaker tongs for moving hot beakers and crucible tongs for grasping smaller items like crucibles. For dry chemicals, reach for a spatula or scoopula to transfer precise amounts without contamination.
Liquid transfers require precision tools. Pipettes deliver small, exact amounts of liquids, while droppers allow you to add liquids drop by drop for careful control during reactions.
Remember Never use the same transfer tool for different chemicals without cleaning it first - contamination can ruin experiments or cause dangerous reactions!
Accurate measurements are critical in science. Digital scales measure mass (usually in grams), meter sticks measure length in metric units, and thermometers measure temperature in degrees Celsius in scientific settings.
The lab has specialized containers for specific purposes. Weigh boats hold materials while measuring mass, while spot plates allow you to perform small-scale chemical reactions. For extreme heat, use a crucible, which withstands very high temperatures. An evaporating dish helps separate liquids from solids through evaporation.
Always protect yourself in the lab! Safety goggles shield your eyes, aprons guard your body from chemical splashes, and gloves protect your hands from hazardous substances.
Pro Tip Always check your measuring tools for accuracy before starting an experiment. Even small measurement errors can dramatically affect your results!
Keeping lab equipment clean is essential for accurate results and safety. Different tools have special brushes designed for their shapes.
Use test tube brushes to clean test tubes thoroughly, reaching all the way to the bottom. Beaker brushes are designed with the right size and shape to clean beakers effectively, removing all residue. Erlenmeyer flask brushes have special designs to reach the narrow necks and wide bottoms of flasks.
Proper cleaning prevents cross-contamination between experiments and extends the life of your lab equipment.
Important Always rinse glassware with distilled water as a final step after cleaning. Tap water can leave mineral deposits that might interfere with future experiments.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
