Solutions!

In class today students had to think and problem solve. They were shown several different mixtures and had to separate them into two groups. The students did very well and most groups began grouping them by mixtures you can separate and mixtures that you can't separate very easily.
We discussed that a regular mixture is easy to separate and you can see each ingredient. It is also very easy to separate out the ingredients. The mixtures we looked at today were pepper and salt, chunky applesauce, chicken noodle soup, Italian salad dressing, and salad.
We also discussed that a solution is also a combination of ingredients, but when you look at it, you can't see each ingredient because they are dissolved. It is also difficult to separate the ingredients out. The most common solution that fifth graders face is salt water. When you look at salt water you can not see the salt because it is dissolved. If we really wanted to separate the solution, we could heat it and cause the water to evaporate, leaving the salt.
Students also brainstormed different mixtures and solutions that we eat! They came up with some great things!

HOMEWORK!
Tonight students are to create their own mixture or solution in the provided baggie! Tomorrow students will write about and present their mixture to the class.

Get ready students...tomorrow you will need your serious rhyming skills!

Just another crazy mixed up day!!

Mixtures

Today we learned that a mixture is a combination of 2 or more ingredients that is easily separated. We experimented with different mixtures and even practiced choosing the correct the tool and separating them. Some mixtures can be separated using tweezers, magnets, strainers, and our hands!
Here are some of the mixtures we "played" with today!
Just another mixed up day in Science!

Noisy Friday!

Today we studied Sound. Sound is caused by vibrations. Our different sound stations proved that!

Mrs. M does not even have a headache! Woohoo!

Today the fifth grade teachers unveiled our new t-shirts! We loved wearing them and showing off the fact that our students rock!

Just another happy day!

Sick...

Mrs. M has some sort of stomach virus. I missed my kiddos today and will unfortunately have to miss them tomorrow too. I need to build my strength back so that I can be the best teacher I can be. Be good for the sub. I left an experiment for you to do without me, and we can go over it when I get back!
I love my sweet students!

Conductors and Insulators!

Today we did an experiment to test the conductivity of different materials. A conductor will allow heat to flow through it easily. A material that does not allow the flow of heat is called an insulator. Today we found out which materials would be good insulators or if they would make better conductors!
To do this, we covered bottles of hot water with different materials. We found the temperature of the water, then covered our jars securely. After twenty minutes, we uncovered the jars and took the temperature again. We then had a class discussion about which materials helped hold the heat in better and which materials seemed to let the heat flow out of the jar. The materials we used were
foil


felt


fabric


bubble wrap


paper bag


and wrapping paper.



While waiting the twenty minutes, we put a wooden, plastic, and metal spoon into a bowl of hot water. We all felt each spoon and found that the metal got pretty hot! We concluded that metal is a very good conductor of heat! I guess that is why we cook with metal pans!

We also learned a new song! The Magnet Family! I will get a video of this and put it on soon!

Science was fantastic today!
