Physical Change is melting, boiling, breaking, cutting, and or dissolving. Chemical Change is producing bubbles, getting cloudy, temperature change, color change, or change in taste/smell. The burger example really helped me understand better what the difference was between psychical and chemical change. I thought it was really interesting that the bubbles in boiling water are just water vapor. I thought it would be oxygen gas or something. This video was really helpful! JMJ
When you Chemically change something you are changing the cloudiness, bubbles, tempture, color, or taste/smell. When you physically change something you are boiling, melting, cutting, or dissolving. I thought it was cool how the salts reacted with heat. If we use pink hemalain salt will the flame color be pink? G.J.G.
I found that when he did the burger example that, that relay helped me understand the difference between physical and chemical changes oh and in and out burgers are really good you should really have one. I did find that when he said that the water evaporating was a physical change but when he said that the vinegar and baking soda was a chemical change e that was pretty weird I also thought that what he said about the salt made how a different color pretty cool can we make fire works in class?
There are two types of changes. Physical change mostly changes the appearance, some physical changes are: Melting, Boiling, or Breaking, etc. Some examples: When a burger is broken down by your teeth, that is considered a physical change. Or when ice melts to water, that's another physical change. Chemical changes are changes in the substance, like when a burger is processed through your body. Examples are: Produces bubbles, temperature change, or color change. ADC
there are two types of changes in the world there are physical and chemical. physical change is when for example ice melts it gets smaller and wet and even turns mushy, physical change is sight smell texture so on. chemical change is when the chemical compound of a substance is changed by another chemical. bmm
this video was very helpful. it had lots of interest and helpful facts, such as how to classify the chemical compared to fiscal. melting, boiling, breaking cutting and dissolving are all Characteristic of fiscal change. Characteristic of chemical change are producing bubbles, turning cloudy, tempter change, color change and change in smell. E.D.B
The five elements that are the key to physical change are if the product or whatever is melting,,boiling, breaking, cutting, dissolving. Appearance changes but substance does not. The guy said boiling water is a type of physical change. I did not know why water bubbles once you heat it up, now I just found out that the bubbles have water vapors in them. Chemical Change symptoms are the Product produces bubbles, turns cloudy, its temperature changes, its color changes, and its smell or taste changes. Chemical change is basically when the substance changes. This video helped understand what physical and chemical change. A.P.H.
Its cool how he explained physical and chemical change using a hamburger for an example.
Physical change: Appearance changes, but not what the substance originally is does not change. this includes melting, boiling, breaking, cutting, dissolving, and so on.
Chemical change: when a substance changes, and it is now something completely different. This change cam mean turning bubbly, cloudy, a change in temperature, color, or even in smell and taste.
I appreciated all of the well explained examples in his video. 2H2 + O2 YIELDS 2H2O. It was nice video, but sadly it didn't tell me anything I didn't already know. L.G.S

This helped a lot with my understanding of physical changes and chemical changes. I learned that when something is broken, melted, or boiled, it is a physical change because the form of the object changed, not the components that make up the object. A chemical change is when the reactants of chemicals makes new products, like when vinegar and baking soda are put together, they make a bubbly gas. Thanks Bozeman Science! MJS
Using an In'n'Out Burger as an example made me hungry! He talked about how when he chews it, the burger breaks down into a PHYSICAL change. Then it goes through a CHEMICAL change when he digests it. PHYSICAL CHANGE: Changes shape, size, or other ways of affecting the form. CHEMICAL: When a substance combines with another. It changes the whole substance in odor, colour, heat, or sound. The bubbles in boiling water is not hydrogen and oxygen, it's just water in gas form. I thought it was odd that dissolving sugar into tea is a physical change, not chemical. This video was actually more understandable.
this is a good video to explane the the changes but the part that says it becomes you is kind of a weird way to put it. the rest of it was relly good thought CML
