Making Butter in the Classroom


Butter is a food product only made from milk.  It has been made for thousands of years.  Milk contains carbohydrates, vitamins, proteins, and fat.  It is the most complete food.  Milk spoils easily, so people had to come up with other things to make from milk.  Butter is mostly fat and does not spoil easily.  It was a perfect option. 

 
Since Thanksgiving is almost here I wanted to share an easy way I make butter with students.  This is a great time to look at how butter was made in the "olden days."  Butter is still made the same way, but, of course,  in a  factory for most.  Kids will be so surprised at how easy it is to make butter.  There is great science in the making of butter.  This activity is great in a classroom, at home, or a scout group. 



Supplies

Heavy whipping Cream

Clean marbles

Baby soda bottle test tubes or 6oz. baby bottles.

Plastic knife or long popsicle stick

Graduated cylinder

Small bowls
 
 
 

Procedures

1. Bring Heavy Whipping Cream to room temperature.

2. Place the marble in the test tube.

3. Measure 20ml of heavy whipping cream and pour it into the test tube.

4. Screw the lid on tightly.

5. Shake the test up and down for 5 minutes.

6. Pour out the left over liquid.  This liquid is the butter milk
 
7.  Inside the test tube  should be thick butter.  Use the popsicle stick or a knife to take the butter out and put it into the bowl.
 
8.  This butter is salt free, so you could add a little salt to taste. 
 
9.  Spread on crackers or butter. 
 
ENJOY!
 
The Science Behind Butter
 
 
The first step to making butter is to let the milk stand.  The cream will float to the top.  The cream is skimmed off the top.  The cream is then brought to room temperature to crystallize the butterfat globules.  This is a very important step.  Before large factories the cream was placed in a churn.  Churning means to work the liquid cream so the fat globules come together to make butter.  The fat globules are more attracted to each other than to the water they are suspended in. 
For this activity, cream is poured into a baby soda bottle test tube with a marble.  The marble helps to speed along the process.  The students will shake the test tube.  This will force the fat globules to come together and separate from the water.  It is called coalescing.   As the tube is shaken the cream will go through stages.  It will become frothy, soft and course whipped, and finally a glob of yellow butter.  Our butter will be soft because it is not cold.  When making butter the butterfat would be drained off and the butter would be rinsed with water.  Salt could than be added for taste.
 
To show the students the difference in fats in cream I created a science journal.  It helps to show the importance of fat in creating butter.  It is a great way to take the activity and turn it into an investigation.  It also is a wonderful science fair project.  If you are looking for a way to teach the scientific method and exploring butter this is a great way to do it.

Making Slime in the Classroom

You have been Slimed!!
 
 
Recently a students said, "This is so much fun.  I love it when we get to make a mess."  Messes can be a great part of learning.  Slime is one of those great things.  Perfecting how to maintain classroom management, not making the custodian upset, and having it be hands on can be very intimidating.  Here is a recipe and steps that I think is teacher friendly, as well as giving the students a hands on experience.  The goal is to have your solutions mixed ahead of time and then all the students have to do is mix the two solutions together.  You can have the class help mix the solutions too.  That is all up to how you run your classroom.  In this busy world of teaching it is hard to squeeze in the science, but it is so important.  With a little prep your students can have a wonderful slime experience.

Here are some pictures from a recent class I did this with.  The students worked in groups of 3.  The recipe made enough for each of them to use and take some home.  Check out the recipe below.

 
 Students enjoy pulling the slime out of the cup.  Yes, it will sound like the noise putty you can buy. The kids of course will say it is farting.

Perfecting Leaf Chromotography

 
I decided to test to see if rubbing alcohol or nail polish remover(acetone) would create the best leaf chromatography.  After trying leaf chromatography recently with dismal results this worked much
better. 
 
Supplies
Flat Coffee Filter
Quarter
Spinach Leaf
Small Mason Jar
Pencil
Tape
Acetone
50% Isopropyl Rubbing Alcohol
Safety Goggles
 
Steps
 

1.  Cut the filter paper into a rectangle with a point like shown. 
 
2.  Place the spinach leaf on top of the filter paper.  Roll the quarter over the spinach leaf to press a green line into the filter paper just above the point.  It is a good idea to let it dry about 15 minutes.
 
3.  Attach the top of the filter paper to the pencil using tape.
 
4.  Pour about an inch of acetone into the mason jar. 
 
5.  Place the tip of the filter paper into the jar.  Make sure just the tip of the filter paper touches the acetone.  The pencil will help balance the paper.
 
6.  Observe the acetone traveling up the filter paper and carrying pigments along with it.
 
7.  When the acetone almost reaches the pencil take it out of the jar.
 
8.  Follow steps 1-7 for 50%Isopropyl Alcohol
 
My students enjoyed the leaf chromatography.  They did find that the colors fade rather quickly on the filter paper.  Below are pictures of the acetone being used.  We have green, bluish green, and yellow.  The acetone has more fumes.  We tented some aluminum foil over the top and that helped.  It is also good to have an open window. 





Here is a comparison of 50% isopropyl alcohol and acetone.  You can see that the alcohol on the left did not have much color separation. 



 
This would work well as a science project.  There are many other changes that can be made.  Isopropyl alcohol comes in different strengths.  The are many different types of filter paper.  Think of all of the leaves you could test.  Just remember to practice good lab practices and be safe with any chemicals used.

Science: Its' All Elementary - Blogging has Begun

Hello and welcome to my blog.  My name is Kimberly Scott.   You may have seen my science activities on Teacherspayteachers.com.  I am a hands on science educator, mom, wife, and explorer of the world around us.  I love to tinker and come up with new ways to try experiments.  I like to make sure experiments for children work the first time.  There are so many times I find a great experiment on-line and it does not work like they say.  Part of science, but still very frustrating.  I like to make sure the steps and materials in investigations will work.  Possible errors happen and they are a learning experience.  When things don't go the way you think they should, it is a great time for the kids to experiment and discover. 
As teachers we typically do not have the time to deal with experiments not working.  We picked that particular experiment because it would show the students a specific concept we are teaching.  Sometimes we have the kids just explore to just see what happens, but other times we need clear data for students to analyze.  That is what I strive to provide for teachers.  Not only do I provide directions, but I like to provide clear tested directions and worksheets to go with it.  The hope is that all you need to do is purchase the supplies, print the copies,and do a little preparation.  You will then be able to provide a clear investigation, following the scientific method, to help teach your current concept.  It also provides a great memorable learning experience.
Yesterday I was working on Color separation in Leaves (Chromatography).  It is always fun to see all the colors that are in leaves.  I decided to see if a maple leaf would work well.  I rubbed a nice line of green on the filter paper.  I let it dry for about 15 minutes like the directions said.  I placed the filter paper into the rubbing alcohol.  I will tell you rubbing alcohol does not move up filter paper as fast as water.  Plan on 30 minutes to get results.  Well, my results were dismal.  There is some yellow that traveled, but nothing that will really get the point across that leaves contain numerous colors.  Nothing like the pictures I saw on-line.   All tips are welcome!!!

Time to think of what I did.  First, I used the circular coffee filters.  I think I will try a higher grade of filter paper.  Secondly, it is fall.  The leaves are beginning to fall and lose some of their brightness.  Most likely the leaves just don't contain as many pigments as leaves in the middle of summer.  Many websites kept mentioning using spinach leaves.  There must be something to that.  I will be purchasing spinach leaves today or tomorrow and hopefully I will have a picture of leaf chromatography to show you.  Fall is a great time to teach about mixing and separating colors.

Well, I have completed my first blog.  What is the toughest part?  Decorating and formatting it.  Watch in the weeks to come as I become more and more familiar with clipart, links, and many other gadgets.  So many blogs look so beautiful and really catch your eye.  It takes time to figure it all out.  The reality is that I am spending most of my time working on activities for my students.  As I learn, realize it is the content I am providing in my blog that I feel will help inspire teachers and students to perform great investigations.  I also hope to learn lots of great tips from my followers as well.

Yours in Science,

Kimberly Scott
