Each delight-filled Global Topic Introduction is combined with dozens of smaller fascinating topics.  Every year, three fascinating self-guided notebooks are built. Reading and experiments are also added to make one of the most fascinating, delightful and innovative science programs on the planet!

A Fantastic Year!


You do not need to read the rest of this.  It describes what the program is about and why.  To jump in, just read what is in this box.

Getting started is easy:

  1. Print the 3 Printables for CrossWired Science (CWS) – Mighty Feathers (MF), Sound (SO) and Fluid Dynamics (FD)
  2. Put each in a notebook. (Ones that give a place for a cover sheet are nice.)
  3. Begin with any one. “The Big Project” is at the end of each Global Topic. Mighty Feathers does not need the website. It is easiest to begin there, but it is not necessary.

"The Field"

The Field shows many concepts
in the Science Portion of a student’s mind.

CrossWired Science endeavors to “build and greatly wire”  all the different-sized concepts in your child’s mind.  Many diverse concepts are often “worked on” simultaneously

in the same week. 

This keeps the ”fascination top” spinning in a student’s mind!



The “Loops” signify all the child’s “wiring” in Science. The space between the “strokes” in this case is the student’s knowledge of Fluid Dynamics.

Each of the 20 Global Topics are introduced as early as possible, and broadened every succeeding year, with major broadening happening at different intervals.

20 increasingly intensive Global Topics (GT) and dozens of Major Topics are thoroughly mastered in the school years for lifetime retention. At the same time, students cover hundreds of mini-topics. These are carefully re-visted and broadened in delightful ways all the school years, but mastery is caught as a pleasure rather than being required as it is with Global and Major Topics.

CWS will use technology to bring near complete mastery of delightful detailed Deep and Fascinating Science in both the Global and Major Topics, but we have not yet revealed how we will do this.

CWS For a Full Year of Science!

Using CrossWired Science’s affordable (by design!) website provides a very exciting, and amazing  full year of science. We plan to add another year of Science each year for a number of years to come to continue this.   Here are a few insights to help you to understand and to use the current website and the free Printables.

1. CWS For a Full Year of Science!

Five components make up the first one-year CWS program.

Mighty Feathers & Birds Major Topic (1 month), Fluid Dynamics Global Topic (3 months), Sound Global Topic (3 months), The Big Project (1 month) and Books (Interspersed).

2. CWS is Designed–by intent–to be a Very Effective Eclectic Science Year.

CWS is all you need for 8 months of learning.  Use the 3-month Printables of CrossWired’s Sound (SO) and Fluid Dynamics (FD) plus the one-month Printable for Mighty Feathers (MF).   Then, for the last month, do the Big Project described in the Printables, while doing some review.  Read books throughout the program as described in the Printables. You’ll have 32 to 36 weeks of science covered.

Our plan is to release 3 more Global Topics and one more Major Topic like Mighty Feathers every year so you can keep using CWS as the years go by.  There are 20 Global Topics.

3. Using the Printables is fantastically easy.

There are currently three Printables with CWS: Mighty Feathers (MF), Sound (SO), and Fluid Dynamics (FD). 

Simply follow the Printables.  As parents, you don’t have to do anything!  Let the Printable and the website do it all. Just check progress,  talk about what’s covered, and have fun!

Print each Printable and put it in its own notebook. (When you finish CWS, there will be 20 “Deep Science” notebooks in all. These will cover a fantastic array of God’s wonders in Deep Science.

The notebooks will be added to year after year. CWS will always be coming back to His wonders and mastering them, both to strengthen a student’s love for God and confidence in His power, beauty and intelligence.  These notebooks–with the website– powerfully build a science mind.  A science mind is a mind that thinks as cutting-edge scientists do.

4. There are vital, behind-the-scenes education truths governing how we do CWS.

The Fascinating and Delightful has much higher retention than the Dull.

Students will remember two to ten times more and, in some cases, one hundred times more if they truly find material fascinating and delightful. Regardless of how organized Dull is, it can still be quite uninspiring.  This greatly hinders learning and tremendously causes material studied to fall from the memory of students.

This is not to throw conventional science instruction under the bus. The goal of conventional science is to present science is a clear, orderly way moving from A to Z.  Every textbook in the world has some inherent dullness to it.  The secret to the fascinating and delightful in traditional science is a great teacher or a great mom or dad who can add the spice. 

If your child is in a traditional Science class, our hope is that CWS can add delight and information that very much glorifies the Lord.  CWS will help add spice to Biology and other science classes!   Always remember this:  IT IS ACADEMICALLY POWERFUL TO LEAN SCIENCE TOWARD DELIGHTFUL DEEP SCIENCE: THE MORE THE BETTER!

Family & Individual Customization greatly increases lifetime memory and motivation.

Every science curriculum needs to provide for some time for self-direction. For younger children, this is often directed by parents and this is good.  But in time, a little more can be given over to the student.  This is very profitable for learning–and quite fun.

There are many things that are delightful to everyone; sweet is sweet to all of us. God made us this way.  But we all also have unique God-given bents.  God may show His extreme glory and wonder to one person through insects and space and through plants and horses to you. God gives us all unique interests that we understand more the reasons for as we walk through His life and purposes for us.

Too much self-direction can be a mistake.  

Don’t let teens (no matter how smart they appear) entirely steer their own science ship.  They need a captain who knows the direction in the immense world out there that they have not experienced yet. A recommendation is to let them steer about 10%-15% of the time, if they are diligent.

Science needs to be a great experience for the entire family.

Read alouds, CD’s, experiments, field trips, seminars, oral reports, specialized classes, and more can be great to share as a family. CWS firmly believes that parent-customized guidance needs to be present in the midst of a science curriculum. We build in certain sections which allow families to enjoy science TOGETHER in every CWS calendar and especially in our year-long plan for CWS.

We want to help parents learn how to customize their science instruction and be able to discern great science opportunities when they see them. This verse has application in choosing many things:

“But solid food is for the mature, who because of practice have their senses trained to discern good and evil.” Hebrew 5:14.

As a family, you need the freedom to spend part of your science time pursuing what is fantastic especially for you. God uses these times to wonderfully strengthen your family and to powerfully shape your family’s future. Never let it slide past you there is tremendous joy learning science together.  The long-term family and educational benefits are HUGE.

5. There are decisions to make while using CWS.


For the First and Second Timer’s reading (grades 1 and up), we heartily encourage reading the Benge YWAM scientist biographies. These are found in the Reading list in the Reading lessons in CWS. These may be purchased through the SHOP button in the top menu on the website with free shipping at a good savings over Amazon.

These are excellent for the entire family and can be quite fun and very meaningful as family read-alouds at night.  There is quite a list of other available titles of Christian missionaries that can be read together also.  Start a new family read-aloud tradition!  We guarantee you’ll be VERY glad you did!

For older students, we find Creation and Answers magazines are great additions, also.  Back issues for Creation are affordable and excellent.  The Creation magazine centers only on science and the Answers magazine includes apologetics.  These are fantastic as an ongoing family resource.  Read together after dinner!

Other great options are suggested in the Reading Lesson. Choose what delights.

Unit & General Links (Be sure to view more than once!)

It is a great idea to watch many of the General Video Links and Unit Video Links we suggest in each Global Topic of CWS more than once. These are often fantastic for the entire family.  General links tend to be better for all.

Repetition for mastery is very important. Much of the material in the CWS Link Lists is scientifically very powerful and is amazingly retainable if seen three or more times over a couple years. Link retention might increase ten times for many students if the material is just covered twice.  The Printables build in necessary repletion of the greatest material. We’ve got that covered for you.

As new material is released by CWS, you’ll notice that every great slice (our animations) and every great video link is covered at least 4 times over 6 years and is expected to be greatly mastered for lifetime retention.  “Zips”–heavily academic insertions–will begin to be added to existing links beginning next year for Second Time Students.  These don’t diminish the delight of the slices, but they heavily increase their academic value.

U-Choose, Reinforcement, Research, Field Trips, and Experiment Lessons

The full-year CWS program has eleven of these “group lessons” per global topic (22 total each year). These are individual lessons in the Global Topics, Sound and Fluid Dynamics.

Your family can choose activities in these 5 Lesson-types. These are great for family participation. The possibilities are endless –take a field trip, listen to audio dramas, explore with a digital microscope and dozens more.

The list of supplemental materials and activities you can add to CWS in these 5 areas is fantastic!   There is much deep science in all these suggestions.

6. For Older Students: Reviewing Gold Digs and Digging Deepers is VERY Important.

A Gold Dig is a topic studied alongside the Global Topic which is an entirely new and different topic. For instance – Gold Digs in Fluid Dynamics (FD), contain 5 interesting, extensive, and VERY informative lessons on Bones.

These can be done with students as young as six IF Mom or Dad or a teacher goes through each slowly alongside the students. The information, however, is perfect for High School Biology students as well.

Digging Deepers are the same type of written-visual lesson found in the Global Topic Sound (SO). These 5 lessons, however, deal with the Global Topic Sound and include other fascinating topics such as the amazing sonar of bats and dolphins and the roar of lions.

Advanced students have a second shot at the Gold Digs and the Digging Deepers. The second time through will increase retention many times over for most students. We include them twice in the year-long CWS schedule.  Just follow the printable for the “how to’s”.


7. Using Digital Supplements We Give throughout the Year.

We will be sending you FREE animations, links, supplemental printables, roundtable discussions and interviews as we produce them year after year as long as you are enrolled in CWS.  No topic is ever left behind!

These will increase the depth and amount of material covered in the released Global  and Major Topics and Mini-Topics on our site. As material is revisited and expanded, lifetime retention and understanding is tremendously increased.

8. Use CrossWired for High School Biology?

Many sections in Mighty Feathers (MF) and the Global Topics, Sound (SO) and Fluid Dynamics (FD) are GREAT for a conventional Biology Class…and we are just beginning!  For just $15 for class-enrolled students per year, many wonderful things can be added to a biology class. But our goals are different from those of traditional Biology.

Our goal is that by the time a child goes through nine years of CWS, they will be able to CLEP Test out of Biology, have half of Chemistry completed and have a wildly good foundation of applied physics in both God’s Nature and in man-made innovations…And a truckload more!

Wrap Up

The material in CWS Global Topics (Sound and Fluid Dynamics) plus the free Mighty Feathers unit is well worth remembering for a lifetime. It all builds a great science foundation for a science mind and it is greatly glorifying to God. It will significantly strengthen a student’s–and family’s–faith and confidence in God.

This is why we do what we do.

Have a beyond-wonderful God-blessed time!
