This might make some of you scream, but I'm going to bring in the law of conservation of mass (or matter). It can neither be destroyed or created, so I think that the jar will still weigh the same. BUT! that is only a theory. So I might be wrong. XD
(I don't even know if i got the conservation of mass thing right (^_~)]]> 2017-03-08 17:56:03 UTC https://padlet.com/annadalynz/kv79w0bfojbh/wish/158753771 https://padlet.com/annadalynz/kv79w0bfojbh/wish/158753958 We think the mass of the jar will change over time. We think the mass of the jar will decrease, because the plant will eventually die. Since the plant will eventually die the plant will decompose and make the jar mass lighter. ]]> 2017-03-08 17:56:32 UTC https://padlet.com/annadalynz/kv79w0bfojbh/wish/158753958 https://padlet.com/annadalynz/kv79w0bfojbh/wish/158754081 I think that the mass of the jar will increase. The water mass will neither increase nor decrease, because when it evaporates, it has nowhere to go, but to the top of the jar. The mass of the plant will increase, if it is not full grown, and if it will reproduce, the mass of all the plants will be greater. As well as the plant decomposes, that means more volume, AND weight, which is mass.

Yes it will change mass because as the soil becomes dryer then the density is less. ]]> 2017-03-08 17:57:00 UTC https://padlet.com/annadalynz/kv79w0bfojbh/wish/158754136 https://padlet.com/annadalynz/kv79w0bfojbh/wish/158754420 2017-03-08 17:57:45 UTC https://padlet.com/annadalynz/kv79w0bfojbh/wish/158754420 https://padlet.com/annadalynz/kv79w0bfojbh/wish/158754436 We think that it would either increase and decrease or stay the same and not change at all m 99because it could increase and decrease when evaporation occurs because it will be lighter then when it condenses and goes back into the soil it will get heavier because liquids are heavier than gases. ]]> 2017-03-08 17:57:46 UTC https://padlet.com/annadalynz/kv79w0bfojbh/wish/158754436
