So we found solid. We found liquid. Solid AND liquid? Oh come on??

Egg, paint, ice cream float?

This is junior school!

Ice

TheHeirOfSlytherin Sat 15-Sep-12 23:06:41

or mercury

Custard

SloeFarSloeGood Sat 15-Sep-12 23:08:02

Cornflour and water mixed up.

Custard

Butter?

dh says glass??

Chocolate

Funnylittleturkishdelight Sat 15-Sep-12 23:08:57

jelly!

ice cream

Jam

most stuff that reacts to being heated/frozen

SpanglyGiraffe Sat 15-Sep-12 23:09:06

Candle wax? confused

NeverKnowinglyUnderstood Sat 15-Sep-12 23:10:12

just googled and it says something that is at it's own melting point. (but I guess has not actually melted?/)

Saturated fat?

Yourefired Sat 15-Sep-12 23:11:36

Google sols and gels, plucked from ancient a level chemistry memory so could be wrong. Remember custard and jelly given as examples.

wanderingalbatross Sat 15-Sep-12 23:12:45

Cornstarch and water mixed! Google 'oobleck' smile

Yourefired Sat 15-Sep-12 23:13:00

Wow just read op properly, primary school. Scary.

numptymark1 Sat 15-Sep-12 23:13:08

liquid takes the shape of a container it's in
solids have a fixed shape unless they are altered by a force (pushing/cutting etc)

so talcum powder/sand/custard are liquids & solids

ice is a solid but heated it's a liquid, it's not both things at the same time

Squeegle Sat 15-Sep-12 23:16:05

Apparently glass is both. I find that hard to understand......

Mibby Sat 15-Sep-12 23:18:49

Helium at absolute zero (0 deg kelvin)

Glass is actually a supercooled liquid.

Very old glass windows become thicker at the bottom than the top.

TeamEdward Sat 15-Sep-12 23:21:35

Glass is liquid, but just takes a r e a l l y long time to take the shape of it's container. Ever seen the original windows in really old houses? They look warped, but were once relatively clear. Time has meant that the glass is slowly liquifying.

TeamEdward Sat 15-Sep-12 23:22:00

x-post!

Frontpaw Sun 16-Sep-12 08:24:05

The first thing that popped into my mind was a triumphant 'non-Newtonian Fluid! Ha!' I'd heard of oobleck too - but for an eight year old... I think I'll get him to mix up some quicksand and take that in.

Thanks for the ideas! I wish the teachers would give the kids a cue though sometimes!

Sand and talc are solids not liquids.
Yes an amount of sand will take the shape of the container it's in and will pour however you have to consider the actual grain of sand in determining it's state.
One grain of sand is a solid and does not take the shape of a container.
You could fill a bowl with peas and pour them out but this does not mean they are a liquid.

ThisIsMummyPig Fri 21-Sep-12 23:22:14

I might be a bit thick, but I thought that things were liquid until they got to freezing point, and then were solid. Things like jelly are plasmas (I think)

Definitely glass.

Freaky stuff..... Acts pike platform but when it's put in its tub it settles like a liquid. Id love to know what happens when it's left lying on a surface but I'm not sure ds1's OT would appreciate the mess experiment

SummerRain Fri 21-Sep-12 23:26:46

Like playdoh.... Damn smartphone

Himalaya Fri 21-Sep-12 23:28:57

Maybe they just mean everyday things that the children are familiar with both as a solid and a liquid - e.g. Water, egg, butter etc...I.e. sometimes solid and sometimes liquid.

Not a very well phrased question though.

The thing with corn flour is fun though grin

SummerRain Fri 21-Sep-12 23:29:29

Also liquid crystals as in LCD screens

SloeFarSloeGood Sat 22-Sep-12 00:09:03

I think we might be over thinking this...

SummerRain Sat 22-Sep-12 00:44:40

My father always taught me to answer the question a teacher actually asks, not what they meant to ask.

DilysPrice Sat 22-Sep-12 00:46:06

Graupel.

And no, he wasn't popular with his teachers and neither was I wink

Glass, the tar in tarmac.

InfinityWelcomesCarefulDrivers Mon 01-Oct-12 19:29:34

Petrol
(surely it doesn't mean solid and liquid at the same time!)

InfinityWelcomesCarefulDrivers Mon 01-Oct-12 19:29:52

rock

ouryve Mon 01-Oct-12 19:31:45

Glass (it's actually a liquid as it flows, albeit slowly, but feels solid)
A thixotropic mixture of cornflower and water (can't be compressed, but pours)

meditrina Mon 01-Oct-12 19:32:48

Poo?

bumpybecky Mon 01-Oct-12 19:34:40

toothpaste?

Gravy - liquid when I make it, solid when dh makes it.

Lava.

Brie.
Mercury.
That mixture you get when you mix cornflour with water?

DawnOfTheDee Mon 01-Oct-12 19:53:09

I thought the 'glass is a liquid' thing had been disproved? It's thicker at the bottom in old buildings due to the process they used to use or something.

ValiumQueen Mon 01-Oct-12 19:57:18

The only one I know is glass

InfinityWelcomesCarefulDrivers Mon 01-Oct-12 22:18:50

Even if it is a liquid (which I got told was wrong in my science homework angry) it's not also a solid. Is it not asking for substances that can be in more than one state? Water, petrol, rock,most plastics I imagine. Surely things can't be both a solid and a liquid at the same time.

InfinityWelcomesCarefulDrivers Mon 01-Oct-12 22:19:34

love gravy , dependng on who makes it grin

2beornot Mon 01-Oct-12 22:30:26

Milk is a solid dispersed in a liquid (like emulsion). Is that what they are after?

sausagesandwich34 Mon 01-Oct-12 22:32:54

custard!

but I've just realsed this thread is a few weeks old so, OP did you ever get the answer from the teacher?

converseconvert Mon 01-Oct-12 22:34:06

Lava

hi every one i am new member to all of you
thanks

BertieBotts Tue 06-Nov-12 08:36:20

Hi Zaki, best to start a new thread if you want to introduce yourself, or just jump in smile Click on "Active conversations" at the top though or you'll be reviving old threads which are no longer relevant.

SnowLeopard27 Sun 17-Mar-13 17:44:16

Creme freche??

Theas18 Sun 17-Mar-13 17:54:22

"things that are a solid and a liquid" Needs clarification!

At the same time?

At what temperature??? (assuming atmospheric pressure is a given)

As a sort of scentist Im afraid I'd say stupid q- just about everything is a solid and a liquid an a gas at different temperatures.

The answer in 1 primary age substance has to be cornflour in water.

kritur Wed 27-Mar-13 12:46:27

Bad wording of a question surely... Shouldn't it be name some things with both liquid and solid properties"? Eg, sand.

Vickibee Wed 27-Mar-13 12:50:24

Most things can be solid or liquid it just depends on the temperature. Eg iron is a solid at room temp but melts if you heat it up enough this is a silly question form a science perspective most elements can change state.

OP come back and tell us what they said (I am infinitywelcomescarefuldrivers btw)
