https://padlet.com/gakiho/kwgons8hh88xqi2a You were given one piece of evidence (properties of metals), so build a model (together) that represents metallic structure (ABSOLUTELY NO GOOGLING). Take photo or tape a video , and justify why your model demonstrates the properties. Once given new evidence, you should refine their model, and explain why your previous model isn't valid, and why your new one is. en-us 2022-05-20 18:32:26 UTC 2026-02-03 15:28:47 UTC hello@padlet.com https://padlet.net/icons/png/1f9ea.png yko11 https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197789502 Solid metals that have a high melting point suggests that their bond is so strong that it cannot be easily broken, meaning that they are all closely together in a regular form and does not have any movement making their bond to be very firm and strong. ]]> 2022-05-24 14:20:33 UTC https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197789502 treichenheim https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197796564 In this model, we can see that the solid is really grouped up, which makes it have a higher melting point since it is more inpenetrable and harder to melt. When it melts, the particles of the solid spread out and it became a liquid. But in this case it does not hapen since they are in a room tempreature]]> 2022-05-24 14:24:19 UTC https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197796564 https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197804116 In our model, we separated three sets of plasticine; the first one has different little round figures stuck together, representing the particle structure for the solids. The plasticine in the middle represents fire, which melted the solids and turned them into further-apart particles (representing the liquids).]]> 2022-05-24 14:28:41 UTC https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197804116 https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197837701 When analysing this model, we tried to make it is clear that half of the whiteboard represents the particles before and after being melted by its high melting point. The other half of the whiteboard represents the metal's particles when its shape is altered by a big impact.]]> 2022-05-24 14:49:16 UTC https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197837701 treichenheim https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197841594 when you hammer the solid, the particles will continue together, but they will expand and get flatter, turnig the solid to another shape. When you make the solid into wires, the logic is practicaly the same, but the particles will get a bit looser and not as tight together.]]> 2022-05-24 14:51:51 UTC https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197841594 yko11 https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197843288 When we hammer the solid metal, it would not fully break the substance itself but change the shape by making it bend and be curved. The particles inside the solid will be kept the same that they will still be sticked with each other continuing creating a strong bond. ]]> 2022-05-24 14:52:56 UTC https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197843288 treichenheim https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197898701 Metals can conduct electricity because they have free electrons roaming around the atoms. Since electrons are electricity, having the electrons roam around the atoms makes the metals conduct electricity. Metals are also good heat conductors because of the same reason: the electrons are free and roaming around the atoms. Our group believes that electrons carry both elctricity and heat energy, so that would explain why metals can serve both by being good heat conductors and electricity conduction.]]> 2022-05-24 15:27:38 UTC https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197898701 https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197911012 in our model, we produced a plasticine representation of the particles when a metal is in contact with electricity, which is represented by the green lines in between the blue dots. We then wrote underneath why we think metal is a good conductor]]> 2022-05-24 15:35:46 UTC https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197911012 yko11 https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197914045 Metals that are able to conduct electricity and are good thermal conductors mean that it has a good flow of heat and electricity. Therefore, we represent these flows of heat and electricity as green electrons and placed them in an irregular way in order to indicate that these electrons are free and going around the particles without any typical order, meaning that the flow of electricity and heat is good. ]]> 2022-05-24 15:37:36 UTC https://padlet.com/gakiho/kwgons8hh88xqi2a/wish/2197914045
