Little House Science: Greased Paper Windows

Animals and birds are limited  to what kind of house or nest they can build. When we discover an animal’s home, we can almost always tell what sort of animal it belongs to.  Even with birds, no two kinds will build the same sort of nest.  Some nests are tidy and tight and look just like a bird’s nest from a picture book, while other kinds of birds will be content in a nest that looks like a pile of grass or straw with no visible means of support.  Some birds don’t build at all; they just lay their eggs in another bird’s nest and take off!

Little House Science: Greased Paper Windows

 

People, on the other hand, can build any kind of house they can imagine.

As Charles Ingalls reminds Laura in “The Long Winter,” p. 13, “. . . look at that muskrat house.  Muskrats have to build that kind of house.  muskrat houseThey always have and they always will.  It’s plain they can’t build any other kind.  But folks build all kinds of houses.  A man can build any kind of house he can think of.”

In Laura Ingalls Wilder’s “Little House on the Prairie,  p. 11, she describes their latest little house in Minnesota, which was a dugout.  Now, a dugout is really nothing more than a dirt cave with a door and, if you’re lucky, one window.  The Ingalls’ dugout had a door and a window beside the door, so there was some natural light inside.  “But the wall was so thick that the light from the window stayed near the window.”

Little House dugoutThat window was made of greased paper, not glass.  Pioneers didn’t put glass in their windows until they were sure they were going to stay a good long while; glass was expensive.  It was an investment in longevity.  A house with glass windows represented people who were there for the duration.

Most pioneers started out with greased paper windows because they weren’t sure how long they might be in that particular house.log cabin with greased windowsThe window had to be covered so the insects and wild animals couldn’t get in, but it also needed to let the light in.  Whatever the window cover was, it had to be super cheap.  Voila:  greased paper.

Now, you might be wondering how a window covered with paper could be of much use.  How much light could get through paper?

Not much.  But GREASED paper, now, that was an entirely different thing.

When you grease a piece of paper, the grease fills in all the fiber gaps, and any light that hits it doesn’t scatter; it passes right through. Water doesn’t do this; it dissolves the paper, whereas grease or oil just reinforces the paper and lets the light pass though.  Not transparent, exactly, but certainly translucent. It let enough light through to be useful.

Until someone accidently poked a hole in the paper, or a bear punched through, the family inside had enough light to get by until they could afford glass.

Tragedy in Colorado – The Science Behind a '100 Year Flood'

The Colorado Front Range is still reeling after a major storm dumped more precipitation on areas in 24 to 48 hours than they receive in an entire year. The result was 20-foot walls of water rushing down the sides of mountains, rivers coming over their banks, roads and bridges washed away and houses flooded. Hundreds of roads and bridges washed away across the Front Range. Some places, like the town of Lyons, became islands completely surrounded by water.

What Are the Next Generation Science Standards and Why Do We Need Them?

A few weeks back, we demystified the Common Core State Standards to clearly explain what they are all about. Common Core does not cover science. The Next Generation Science Standards were designed to set a national standard in science and give teachers and their students direction towards college prep and careers in science.

What are the Next Generation Science Standards and Why Do We Need Them? | Steve Spangler Blog

Before the NGSS came into play, the states used the National Science Education Standards from the National Research Council and Benchmarks for Science Literacy from the American Association for the Advancement of Science to guide their state science standards. The standards were high quality and worked well, but are now over 15 years old. In that time, major advancements in science have taken place along with a better understanding of how students learn science.

In 2007, a report from a Carnegie Foundation commission concluded, “the nation’s capacity to innovate for economic growth and the ability of American workers to thrive in the modern workforce depend on a broad foundation of math and science learning, as do our hopes for preserving a vibrant democracy and the promise of social mobility that lie at the heart of the American dream.”

Not surprising, they also found the science and mathematics education in the U.S. was far below expectations and set to leave millions of young Americans unprepared to succeed in the future global economy. In 2009, the United States ranked 14th in reading, 17th in science and 25th in mathematics out of 34 countries.  In 2012, 54% of high school graduates did not meet the college readiness benchmark levels in mathematics and 69% of graduates failed to meet the benchmarks in science.

Science and mathematics education is not just for students preparing for careers in engineering, technology, science or accounting. In our constantly changing, always updating society, the need for higher education in skilled jobs is much higher than unskilled jobs. Many of the fastest growing career fields involve science and math. Information, technology and knowledge turns over about every 17 months in our modern society. Think about how fast a smart phone becomes out of date.

Normally we teach out of context. The biology teacher is teaching here. The mathematics teacher there. The english teacher over here. And when it’s time to synthesize? Guess what? We aren’t there.
- Fred D. Johnson, Past President National Science Teachers Association.

The National Association of State Directors of Career Education grouped all occupations into 16 clusters. Fourteen of the clusters require four years of science while the remaining two require three years. The message – “to keep all options open and maximize their opportunities, all students should follow a rigorous program in both science and mathematics,” according to the NGSS website.

It’s not just careers that depend upon advances in society.  We face global problems from pandemics to global warming and climate change to energy shortages. The solutions lie in science and technological discoveries and advancement. Our survival is dependent on our abilities to train future scientists and problem solvers.

From all of these needs and demands for the present and the future, the Next Generation Science Standards were born. The NGSS will provide students a content-rich education across the STEM subjects to prepare them for college and careers. This will ensure all students receive an internationally benchmarked science education. They aren’t a curriculum, but a content plan that all students should learn from kindergarten to high school graduation. States and local districts who adopt them will need to develop their own specific content and curriculum.

Science isn’t just a mere bunch of facts. Science is about the way we think about the world. The way we question the world. The way we communicate about the world. Developing that is a huge piece of the new standards.
- Jonathan Gerlach 2011-2012 Einstein Capitol Hill Fellow, U.S. Department of Energy.

Twenty-six states, a 41-member writing team and educational partners worked to develop the Next Generation Science Standards. The framework was developed by 18 experts in science, engineering, cognitive science, teaching and learning, curriculum, assessment and education policy. The framework was then presented for public feedback and opinion. Then state policy leaders, higher education, K-12 teachers, the science and business community developed science standards grounded in the framework. Those standards were also open for public feedback.

The federal government is not involved or funding the Next Generation Science Standards. It is up to each individual state to choose the NGSS and adapt them. They will also individually decide whether to create assessments connected to the NGSS. The 26 states currently involved are Washington, Oregon, California, Arizona, Montana, South Dakota, Kansas, Iowa, Minnesota, Michigan, Illinois, Arkansas, Kentucky, Tennessee, Ohio, Georgia, West Virginia, North Carolina, Maine, New York, Vermont, New Jersey, Rhode Island, Maryland, Delaware and Massachusetts.

Texas High School Student Gives His History Teacher a Lesson

A video of Duncanville High School student Jeff Bliss has gone viral after a classmate recorded his rant in the classroom last week. Bliss is an 18-year-old sophomore who returned to 10th grade after dropping out. He says he realized the importance of an education for his future. He now takes his education and the learning of others very seriously.

http://youtu.be/3bYv2AKPZOk

Bliss had questioned why the teacher didn’t give the students more time to prepare for a test. She asked him to leave the classroom and he began sharing his opinions of why students were not reaching their true potential. He claimed the teacher only passed out worksheets and packets instead of creating lively and engaging discussions.

In Bliss’ opinion, the classroom time was a waste and challenged the teacher to get the students excited about learning. He also felt teachers must reach out and touch the hearts of their students to truly engage them.

“Just as much as the students need to give an effort, the teachers need to give an effort too.” said Jeff Bliss.

A local television station reached out the school district for comment. The district said they want both students and teachers to be engaging in the classroom but believe Bliss could have expressed his concern in a better way.

One of Steve Spangler’s mottos is to “get it to the dinner table.” Lessons should be so engaging and exciting that the kids can’t wait to share it at the dinner table. Packets and worksheets should support the lessons but not be the entire lesson. No one has ever gotten inspired over doing a worksheet.

So many teachers are inspiring and engaging but some fall short. Teaching shouldn’t be constantly entertaining, but it should spark and excite the students’ interest in learning. Students must meet the teachers halfway. Education is a collaboration.

Where do you land on this issue? Has the teacher been given a fair chance? Did Bliss unfairly rant about his teacher or did he have a point? He obviously touched a nerve, because his rant went viral.

10 Simple Tips for Bringing Science into your Home

By Kim Vij, The Educators’ Spin On It

Do you ever wonder if your child is getting enough Science?

As an educator and parent I have observed over the years that with more and more time focused on Reading, Writing and Math our children are not getting enough time for deeper levels of understanding of in science at school.  Children need more opportunities for hands on exploration and time to process the experiments and concepts at their own pace.  Are you thinking this is something I can help with at home but where to start? Do you know what concepts your child is supposed to be learning in science at school?  It’s easy you can just check the Standards for their Grade Level and support from home.  Your local school board website will have a link.

At The Educators’ Spin On It we try our best to insure that our children have the opportunity to explore science with our After School Express Series and our Tot School Series. We share ideas that you can incorporate as a stay at home parents, after school or on the weekends with your child. You would be surprised how many other subject areas a simple science experiment can lead to… Reading, Math, Writing and more!

10 Simple Tips for Bringing Science into your Home

  • Create a Science Station at Home

Include a Microscope, Binoculars, Magnifying Glass, Tweezers and Containers which are all tools a Scientist Needs to explore.

  • Create Science Trays

Provide items on a science tray such as Magnets, Rocks, Shells or Fossils to provide opportunities to explore and investigate and question.

  • Visit your local library to check out books from the Non Fiction Section

A deep understanding of a concept can come from a self-driven question.  Before you get there ask your child what they want to learn about prior checking out books.  Reptiles, solar energy, volcanos, insects, or chemistry, which topic will it be?  Keep a list posted of the Dewey Decimal System as a menu to choose from and to record on what you’ve discovered already.

Stepping out and into your garden has so many benefits to your child.  Simple good nutrition is the first step as well as discovering the process from seed to plant to fruit or vegetables and all the stages in between.  Does your child know where potatoes grow?  Or how many peas grow in a typical pod?

Have you ever really talked about the chemical & physical changes that happen while something cooks?  Observe active yeast?  Egg or no egg, baking soda or no baking soda?  How can kneading bread change from a sticky mess to something extremely soft and smooth? It’s all explained with science.

Have your children record observations of the world around them.  Create a Hypothesis for an experiment they want to do.  Encourage them to look at the world as a scientist would.

  • Plan Family Outings

Plan trips that support Science Concepts they are learning at school.  A local trip to a science museum or park might be the first step to learning about the land forms and animal life in your area.  Zoo, local nursery, Pet store, Animal Rescue, or even your neighborhood can provide real life experience of many science concepts.

  • Keep simple items on hand for experiments

You would be surprised with how much you can do with baking soda, vinegar, sugar, food coloring, dish detergent, glycerin, corn starch, dirt & seeds. Plus check out Steve Spangler’s Store for some amazing options for teaching children about science.

  • Don’t be afraid of a little mess
  • Ask questions that are open ended

This is one of the biggest keys to remember.  We need to encourage our children to think about a topic and originate their own questions and answers it prevents them from thinking outside the box.  As you see them observing something, encourage them to talk about their questions and observations.  It’s also a great way to build vocabulary too!    

Bonus Tip:  Follow Steve Spangler’s Science Experiment of the Week.  Plus don’t forget you can use Pinterest as a source for Science Experiments.  There are always amazing experiments being shared.  We have a Science Board that we encourage you to follow.

We hope that you’re able to bring science into your home with these simple tips. With these simple tips you can create great thinkers and develop a strong science background.  Plus these experiences will help to build their imaginations to form the skills necessary to discover new things for our future!
