Anti-freeze 5
The normal water is almost all the way frozen. The cup with ten grams of salt is now slushy ice. The cup with twenty grams of salt has very small ice crystels. The cup with thirty grams of salt has not changed.
Antifreeze 4
The cup with plain water was completely frozen after three hours. The one with 15 mil of salt had a lot of slush.
Antifreeze 4
I thought not all of them would freeze but most of them would.
Most of the first one was frozen.
I thought some of it would freeze but not all of it.
Antifreeze 4
I think at the end of the day, 10 will be frozen at the top. I also think 20 will have little ice crystals in it. What we've seen, contral is comepletely frozen and 10 was slushyish.
Antifreeze 2
When we came back to the freezer the three with salt in them were not frozen but the one without salt was starting to freeze.
Antifreeze 1
I think the only cup that will freeze is the one with no salt.
Aintafree
The 30 looked the murkiest.And they will not freeze I think.Will find out in a while.
Antifreeze 1
We put four cups of water in the freezer for 45 minutes.
Anti freeze
I think the 10 is going to freeze more than the 20 or 30.

Class Inquiry Project
1. Ask a question
Why did Mrs. Rehwaldt need to put more antifreeze in her car?
2. Do research
Here is a compilation of your class research:
When you have collected your boiling point data repeat the process varying the concentrations of antifreeze but now freeze them instead of boiling them. Start with pure water. Set your freezer to 310 and put thermometer in water. Check periodically, record temperature when ice first starts to form, do not let water freeze completely. Then put in your 5ml concentrations and put back in freezer. If solutions do not freeze set your freezer at a colder temperature and record temperature when ice first appears. Continue this process through your 25ml solutions.
3. Please comment on this post with your HYPOTHESIS!
What will happen when we add antifreeze to water and try to freeze it?

2. Do research
Here is a compilation of your class research:
Most automobile engines require water to control their temperatures from getting too hot as they run.
An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments and also achieves boiling-point elevation ("anti-boil") to allow higher coolant temperature
So if water was put into a hot engine it simply boiled off and had to be replenished with constant stops to re-supply.
you know how ice cream keeps you cool on a hot day well antifreeze keeps your cat cool on a hot day

When the mercury begins to rise outside, it’s common for car engines to get overly toasty too. Thankfully, there are plenty of things you can do to make sure a temporary jump in temperature doesn’t lead to long-lasting trouble. To help you know what to do if your car overheats, here are 5 easy steps.
- First, always carry an extra bottle of coolant (also called antifreeze) in your car, as well as a jug of water. Engines typically overheat because the coolant’s low, so topping it up will usually solve the problem. Failing that, water will also temporarily do the trick. Plus, that water could be a lifesaver on long, sweltering summer drives. Just don’t drink it all.
- When you see the temperature gauge creeping into the red or a notification light glowing, immediately turn off your air conditioner (since the AC puts a lot of strain on your engine). Roll the windows down to cool off the way nature intended.
- If the problem persists, crank your heater up to full blast. It could make the next few miles a pretty brutal experience, but the transfer of heat away from the engine might just save its life.
- Should the preceding steps fail, pull over as soon as you can. Turn off the engine. If you can pop the hood from the driver’s seat, do so — but don’t risk opening it by hand until the engine has cooled, especially if you see steam wafting off the engine. It typically takes a solid 30 minutes for an engine to cool down enough for it to be safe to handle. If you’d rather let a professional handle the problem, it’s time to call for a tow truck.
- Once the engine has cooled, check the coolant tank. It’s usually a translucent plastic tank near the radiator. If the coolant tank is empty, you may have sprung a leak. Take a quick look under the car. If you notice a drip or puddle, chances are the coolant tank is leaking.
You put anti freeze in your car for 2 reasons. 1 Reason is to keep your engine operating temperature at the specifide level and keep the engine from over heating. The other Reason is to protect your engine block from craking in extreme cold. When liquid freezes it expands and could potentialy crack a weak engine block. Anti freeze does not become solid till around -50F. Also, anti freezes containadditives which reduce corrosion within the engine and the rest of the cooling system.
You use antifreeze because it keeps your car from overheating and freezing. It also keeps cars from having problems in the winter. If you put water in your engine it would freeze or boil.
Most automobile engines require water to control their temperatures from getting too hot as they run. Way back when, this was difficult because a car’s engine runs at a temperature that is greater than the boiling point of water. So if water was put into a hot engine it simply boiled off and had to be replenished with constant stops to re-supply. The invention of the radiator partially cured this problem as the water was kept under pressure which raised its boiling point and kept it from boiling away. But cars continued to have difficulties with over heating even with the radiator.
-- Pure water turns into ice at temperature 0C (32F). What happens if you dissolve different chemical compounds in the water? Will salt or sugar prevent water from freezing or slow down the process? You'll find it out in this 4th grade project. It's simple and can be done in 24 hours.
When you have collected your boiling point data repeat the process varying the concentrations of antifreeze but now freeze them instead of boiling them. Start with pure water. Set your freezer to 310 and put thermometer in water. Check periodically, record temperature when ice first starts to form, do not let water freeze completely. Then put in your 5ml concentrations and put back in freezer. If solutions do not freeze set your freezer at a colder temperature and record temperature when ice first appears. Continue this process through your 25ml solutions.

How Night Came
The three things that were there was a star because night was passing the rooster was there to be the the watchman of the night and the birds were there to announce the dawn of each day.

1. The rooster was called to be: the watchman of the night.
He is to sing as a clue that morning is coming.
2. The birds: "You singing birds you shall sing your sweetest
songs at this hour to announce the dawn of each day."
3. The star: "Glittering star from now on you will be our
sign that night is passing. You shall be called “Morning Star”, and you will announce
the birth of each day."

babies are beautiful
I found a poem about babies, I read it and thought it fit at this time.
This is especially for Mrs. Rehwaldt i hope she has a very good baby which God will provide...!!!!!!!!
Babies are beautiful
Babies are beautiful, truly they are.
Instantly reminding me of a newborn star.
Eyes shining brightly, like star tears of glittering light.
Quickly alert to every move, that happens within their sight.
Faces perfectly molded, all different shapes and sizes.
Bodies rolly polly, full of so many surprises.
The twitch of a baby's mouth when their happy.
I'm positive that this is a smile.
Tiny hands that grip hold to my fingers.
Cooing baby talk all the while
Babies are made out of love.
The most precious substance on earth.
Babies are priceless, no one can measure their worth.
Babies are beautiful, each and every one.
They bring joy and happiness so much fun.
Babies of all different races, together in a giant Bouquet.
We know that babies are beautiful, Let us pray, just maybe,
there is beauty left in all of us, for all was once a baby.

RECESS IS AN UNALIENABLE RIGHT!!!
Recess is an important thing at school
Recess is also important so kids can get there exercise too...
Kids cant run in there class room or in the hallway... even though some still do!!! But thats why we NEED recess... ITS AN UNALIENABLE RIGHT!

Recess is an unalienable right
Recess is the only time we get go outside.
Recess is the obey the time we get fresh air.
Kids need exercise.
recess is an unalienable right!!!!!!!!! :)
RECESS: Should have to happen. Kids are inside all day in a chair. They need fresh air and to run around and be crazy to get it all out!
Recess is a privilege
Recess is a privilege because what if it was raining outside or there is a tornado or a blizzard would the teachers let them go outside? What if a kid did something really bad like punch the teacher. Why would the teacher let them go outside? Indoor recess should be able to be taken away too if something happens or a kid does something really bad too. What if a kid doesn't do their homework or lies and says they had something going on that night so they could get out of doing their homework? What if a kid lies at all? What would the teacher do then? That is why recess is a privilege.
recess is an unalienable right
1. Recess gets rid of our energy by running around. (Joey)
2. It is a lot of exercise when running around. (Joey)
3. You get fresh air outside. (Joey)
Recess is a Privilege
Recess is a privilege because if a kid did something really really bad like hurt somebody and a teacher let the kid outside that would not be right. Another reason why it should be a privilege is because if it was raining out or something crazy was happening outside something bad could happen if they went outside. Kids could also not do their homework and so a teacher would have to keep that person inside. What if a kid lied and the teacher let that person outside?

Recess an unalienable right
She should not take our recess again, so we might disobey,so what we are very good students we want to have fun, run around, and exercise. I LOVE to have recess run around, talk to my friends, yell and have fun. No kid should not have recess they need fun.

I think we should go outside because we need to burn some energy. If we don't we will be very crazy. We will be tired so we don't talk a lot to friends.
WE SHOULD GET RECESS NO MATTER WHAT
We should get recess no matter what.
I want recess in junior high
And it gets our energy out.

recess is a unalienable right
- You can get a lot of exercise.
- You can go wild and get out of you desk
- You can play with your friends in the other class

Recess is an unalienable right
Recess is not just fun it is time,air creative, exercise recess is important.
Another reason recess is important is that we get to spend time together to talk and to be friends and to exercise.
But then again recess is unalienable because it is just a another good subject.well i consider it a subject.
Recess is also the only time to have fun.

If we don't have recess, how will we have a good time at school?

I think recess is an unalienable right,because we get to see our friends.We also get to get some fresh air
and enjoy nature!We get to run play and exercise so we can be stronger.
Recess is a privilege
Recess should be taken away if we are bad. If we are being good we should get extra recess. We should behave, be nice, and more then maybe we would get extra recess more often.
