Lab analysis by Ms. Sutherland https://padlet.com/sutherlandmshc/Bookmarks Please answer the questions below en-us 2022-02-10 18:20:57 UTC 2025-11-02 09:19:29 UTC hello@padlet.com 1. You can determine if a physical change has occurred if there is a difference in things like look or smell but the substance is still the same or if the change can be undone without difficulty. You can determine if a chemical change has occurred if a new substance has been created or if it is difficult to reverse the chance. Other clues of a chemical change are when a new chemical appears, heat or light is given off, bubbles of gas are formed, or a precipitate forms in a liquid.-Noah https://padlet.com/sutherlandmshc/Bookmarks/wish/2049603210 2022-02-15 21:39:48 UTC https://padlet.com/sutherlandmshc/Bookmarks/wish/2049603210 Michael https://padlet.com/sutherlandmshc/Bookmarks/wish/2049781051 1. Fresh lemonade because lemon juice and lemonade are similar but different so it was hard to find the answer


2.snapping pencil


3.burning wood


Conclusion. What I learned so far is that basically everything is a chemical or a physical change. Also atoms are always moving and will never stop]]> 2022-02-16 00:28:03 UTC https://padlet.com/sutherlandmshc/Bookmarks/wish/2049781051 you can tell the difference of physical and chemical changes because they both have different reactions to certain things ~ Ainsleigh https://padlet.com/sutherlandmshc/Bookmarks/wish/2049862023 2022-02-16 01:27:19 UTC https://padlet.com/sutherlandmshc/Bookmarks/wish/2049862023 How can you tell whether a chemical change or a physical change has occurred? https://padlet.com/sutherlandmshc/Bookmarks/wish/2050032300 Physical: The substance only changes forms and can be reversible.
Chemical: Once the substance tests it can’t be changed back.

Give two examples. https://padlet.com/sutherlandmshc/Bookmarks/wish/2050037684 Yes sometimes because when doing Station C the lemon juice reacted but didn’t change and remained the same substance which caused some debate. The Antacid had barely reacted to the water but was still a chemical reaction which I found confusing. - Felicity]]> 2022-02-16 03:44:33 UTC https://padlet.com/sutherlandmshc/Bookmarks/wish/2050037684 Does the mass of the ingredients change during physical changes? What about during chemical changes? https://padlet.com/sutherlandmshc/Bookmarks/wish/2050042013 It doesn’t during physical changes but It can happen during chemical changes. - Felicity]]> 2022-02-16 03:48:37 UTC https://padlet.com/sutherlandmshc/Bookmarks/wish/2050042013 What are some examples of changes you might see happening for a physical change? https://padlet.com/sutherlandmshc/Bookmarks/wish/2050044680 Sometimes there can be a change in colour or a change in the substances shape or form. - Felicity]]> 2022-02-16 03:50:58 UTC https://padlet.com/sutherlandmshc/Bookmarks/wish/2050044680 What are some examples of changes you might see happening for a chemical change? https://padlet.com/sutherlandmshc/Bookmarks/wish/2050046594 One substance could be dissolved or disappear into another substance creating a new one. - Felicity]]> 2022-02-16 03:52:49 UTC https://padlet.com/sutherlandmshc/Bookmarks/wish/2050046594 What science skills did you need to use in this lab? How did you minimize your error? https://padlet.com/sutherlandmshc/Bookmarks/wish/2050049618 I used educated guesses for some stations that didn’t have reactions or I already had done before. For ones we didn’t know we all discussed most of our thoughts and answers to get multiple point of views and a more accurate observation. - Felicity]]> 2022-02-16 03:55:45 UTC https://padlet.com/sutherlandmshc/Bookmarks/wish/2050049618 Megan https://padlet.com/sutherlandmshc/Bookmarks/wish/2050732370 1. Physical - Size, shape, taste
1. Chemical - Bubbles, colors changing
2. Station c and station f, because I didn't know if there was a new substance being created or not. 
4. Change in size, colour or shape.
5. Amount of chemical/substance still left.
6. Read over the instructions a couple times, to make sure I knew what I was doing. ]]> 2022-02-16 12:37:42 UTC https://padlet.com/sutherlandmshc/Bookmarks/wish/2050732370 https://padlet.com/sutherlandmshc/Bookmarks/wish/2051965495 1) physical=a change in size, shape or state chemical= a new substance is formed, unexpected colour change or gives off light or heat
2) station A was confusing because it it was slowly devolving (physical) but it also had bubbles (chemical) 
3)during a physical change the mass does not change but may change in a chemical change
4) change in size, shape or state
5) change in colour or substance 
6) measure accurately and read instructions carefully
