What can students learn about lab safety from Mr Bean?
During his visit, Bean randomly discovers a room labeled “Chemistry Laboratory” in which he enters. Bean, who is clearly oblivious to the concepts of chemical hygiene and standard safety procedures, encounters a sophisticated-looking glassware setup, which he uses to haphazardly mix random chemicals.
What are some chemistry experiments?
- Explore marker chromatography.
- Test which one freezes first.
- Make a bioplastic in your kitchen.
- Polishing silver with chemistry.
- Experiment with Borax.
- Do a kitchen acid test.
- Send a secret message.
- Explode fireworks in your kitchen.
What is a chemistry laboratory?
a place equipped to conduct scientific experiments or tests or to manufacture chemicals, medicines, or the like.
Why is it important to tie your hair in a lab?
Tie back long hair. Loose hair could catch fire when working with a Bunsen burner. Only bring the things you need into the lab. That means you should leave all your personal items, such as bags and jackets outside.

Is Coke and Mentos a chemical reaction?
But the amazing eruption that takes place when Mentos are dropped into Diet Coke or other brands of diet soda pop is not a chemical reaction at all! Instead it is a physical reaction. That means that all of the pieces of the reaction are there, but that they are simply rearranged.
How do you make a chemistry experiment?
- Inspiration laboratories add a twist by adding some colour and making firework pictures at the same time.
- Blow up a balloon with alka seltzer.
- Find out how to blow up a balloon with lemon juice and baking soda.
- Make a lovely, colourful display using milk, food colouring and vinegar.
What does U mean in chemistry?
The unified atomic mass unit (unit symbol: u) is a non-SI unit of mass, defined as one-twelfth the mass of a single 12C atom in its ground state.
What materials are used in a chemistry lab?

What do you learn in chemistry lab?
Laboratory experiences allow students to master specific lab techniques, and deepen their understanding of: Chemical synthesis, analysis, and problem-solving. Technical scientific writing and record-keeping. Professional written and oral communication.
Can you wear skirts in a lab?
Proper Laboratory Clothing Approved safety goggles. A shirt that covers the stomach and lower back as well as the upper arms. Long pants (An acceptable, but not reccommended, alternative is to wear shorts, a skirt, or a lab coat such that your knees are covered when you are sitting down.)
Can I wear ripped jeans in a lab?
Remember the following rules of dress when working in the lab: No open-toed or woven shoes. Legs cannot be uncovered: this means no shorts, capris, skirts or ripped jeans. Shirts and tops must cover the shoulders and upper torso.
Can you wear short sleeves in a lab?
Appropriate clothing must be worn in the lab. In particular, long pants and a T-shirt with short sleeves (or something equivalent) should be worn. The shirt or blouse must cover the midriff area such that no skin is visible, and the shoulders must be covered.
Can I wear slippers inside the laboratory while working?
Wear closed-toe shoes at all times in buildings where chemicals are stored or used. Do not wear perforated shoes, sandals or cloth sneakers in laboratories or where mechanical work is conducted. These shoes offer no barrier between you and chemical and physical hazards.
What should you not wear in a science lab?
Proper Personal Protective Equipment (PPE) must be worn at all times in the laboratory. 1. Clothing: Wear long pants or skirts and closed toed shoes, and tie back long hair. Do not wear shorts, short skirts, sandals, loose clothing, or dangling jewelry.
Are hats allowed in a lab?
Hats if worn, must not obstruct vision or hearing. No electronic devices with the exception of a calculator is allowed.
What are some chemical reactions examples?
- Combustion.
- Oxidation (rusting)
- Biological decomposition or fermentation.
- Cooking an egg.
- Photosynthesis.
- Chemical decomposition.
- Reacting acids and bases together.
- Chemical batteries.
What is a simple chemical reaction?
Synthesis means that two elements combine to make something new. In a synthesis reaction, also known as a direct combination reaction, two chemicals (A and B) make a new substance (AB). Some examples of simple synthesis reactions include: hydrogen + oxygen —> water.
What are common chemical reactions?
- Rusting. Rusting is the process of oxidation, which is the result of a reaction that takes place because of oxygen.
- Digestion.
- Photosynthesis.
- Detergent and Soap Reactions.
- Aerobic Cellular Respiration.
- Anaerobic Cellular Respiration.
- Acid-Base Reactions.
What makes Coke and Mentos a physical change?
Since the addition of Mentos is just speeding up a physical process (i.e. the carbon dioxide gas coming out of solution), the reaction is a physical reaction. This is a state change for the carbon dioxide gas from being dissolved in Coke to a gaseous state.
What type of physical reaction is Coke and Mentos?
After a lot of debate, scientists are now saying that the primary cause of Coke & Mentos geysers is a physical reaction, not a chemical reaction. Their explanation is this process called nucleation. All the carbon dioxide in the soda – all that fizz – is squeezed into the liquid and looking for a way out.
What is the difference between physical reaction and chemical reaction?
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.
What chemical experiments can I do at home?
