Lesson Page. (The Year 1 Printables accessed in both places are the
same.) Download and print the Year 1 Printable 2.0 for First Semester in one of two options, 1. Entire Printable 2. Module-by-Module.

• Module by-Module is the entire printable broken into 12 Modules.

•The printed copy of the Printable is for students to fill in day-by-day. The
digital copy of the Printable is to be used by students daily as they
access the hyperlinked, step-by-step instructions. The Printables 2.0
are your guides to using CWS effectively. You cannot do the CWS
program effectively without the Printables 2.0.

•Complete the lessons on the pages you have printed. Store completed
modules in three-ring binder for easy access. (See Printing below for
helpful suggestions with printing.)


Log in. Download the Beginners Guide for pre-K to fourth graders or the 4-9 Grade Guide. They will greatly help you know how to use CrossWired
Science for different age students. (You will download the Year 1 Printables
2.0 and the Guides will help you to use them. There is one Printable for first
semester and one for second semester.)

Print Student Notebooks? You can save money and use the CWS
Printables electronically for daily lesson instruction and simply use a regular

own pace (Year 1 Global Topics are: Fluid Dynamics, Sound, Electricity and
Acids and Bases) We highly recommend the Experiments and Links
included on the Lesson Pages!

(To access Lesson Pages, go to top menu bar, select Curriculum. Next
select First Timers. You can see the 4 Global Topics there: (Fluid Dynamics,
Sound, Electricity and Acids and Bases). Select which one you desire.
(Acids and Bases will be ready November 1, 2022).

The Printable for Fluid Dynamics and Electricity is filled with exciting
activities and experiments. Download one to your computer and look at the
Concept Pictures, Gerneal Links, Unit Links, Devotions, Crafts, Scientists,
Drawings, Bible Memory, Specific Videos, Gold Digs, Digging Deepers, Book
Readings, Hunts, etc.
Feel free to contact us at if you have any
questions or if you need assistance with setting up your student accounts.


Log in with your Teacher User.

1. You will see a top menu button labeled “Parent/Teacher”. You may find
many resources here including the answer key for the experiments and the
work sheets. Additional Directions can be found here to make your program
even more enjoyable . However, these are not necessary,. The Printables
have full directions for the year you are doing.

2. There is background information in the top menu bar under the topics

3. You cannot access the Student Dashboard through the Teacher User. Nor
can you access be Parent/Teacher button from the Parent User.

4. Directions for accessing grades are found here in the Parent/Teacher

5. Clickable Youtube Links are found here. These do not have Youtube


A mom wrote a few things on our Facebook group, CrossWired Science
Community that we wanted to pass onto you.

I can honestly say I’ve never had a problem logging in, but you can only have one account logged into a browser at a time. If you close the browser window, it logs you out, so you have to get used to minimizing the browser if you’re clicking around from the links in the printable.

Each student should have their own email, coupled with their own
password, set up to their own account.

Ya gotta be logged in. If you’ve closed your browser window, you’re no longer logged in. One easy way to avoid this is to login and minimize your
browser, then click on links in the printables, which will bring up your browser
and go to that link in a *new* tab next to the the one you used to log in. That
way you can wander around in that tab and close it when done, without
logging out entirely.

Some things (like the General Links (urls) are only clickable from the teacher portal. So, to access those, you have to be logged in to the teacher portal (the printable tells you this, but it’s counter intuitive).
However, the same links are *there* on the student portal, the kids just have
to cut and paste them into a new tab in the browser. My kid knew how to cut
and paste a URL by the time she was 5. Ya can’t be logged into the student
portal and the teacher portal at the same time in the same browser. You
*can* be logged into the teacher portal in IE and the student portal in
Chrome or whatever. CWS NOTE: We realize this is clunky. We are just trying to put up a little
firewall that will help protect kids from the negatives of the internet.

CWS NOTE: We teach more than one subject at a a time. This is why we
use Links. One of the great breakdowns in conventional science is that
subjects are covered then not covered again. Very little remains for life-time
memory that points to the Lord.
In CWS, we become the memory jogger and the ones adding to previously
learned concepts. In CrossWired Science, many parents have jumped into
the learning process themselves, then the entire family learns together.
There is nothing significant that we don’t come back to often and deepen.

The multi-subject approach is core to CWS and profoundly affects the life-
time memory of deep science that glorifies the Lord,.

CWS NOTE: These are NOT for those using the curriculum for full time
curriculum. Some use the website to supplement another curriculum. The
calendars are for them

6. THE WORKSHEETS THAT GO WITH THE “CORE” VIDEOS (on the pages with the videos once you pick one and click on it)
CWS NOTE: The worksheets are very short and very easy. They are not
necessary. We put them where they are in case you decide to use them, but
if you follow the Printable, they are not necessary. The worksheets on the
Gold Digs, however, can be helpful.

Want to understand more of the why behind our program?

Before you begin, take a look at the two most important educational diagrams for CWS:  “The Field” and “Loops”.

"The Field"

Year 1: Beginning to Build the Field For A Powerful, God-Glorifying Life-long Science Framework

MINI-TOPICS for CWS Yr. 1: Aerodynamics, Hydrodynamics, Bernoulli’s Principle, Vortices, Turbulent and Laminar Flow, Daniel Bernoulli, Orville And Wilber Wright, Ailerons and Flaps, Kingfisher Hydrodynamics, Penguin Hydrodynamics, Dolphin Hydrodynamics, Fin Types and Swim Patterns, Bird Flight, Insect Flight, Avian Lungs, Box Fish Swimming, Animal And Insect Drinking, Shark Denticles, Nose Turbinates of People and Animals, Cavitation, Cavitation and Ship Propellers, Cavitation Erosion, Mt.

"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 a young person’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 early, and broadened every succeeding year.  Significant and major broadening occurs at different intervals throughout the educational experience.

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

CWS will use technology to reinforce complete mastery of 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. 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.

Here are a few insights to help you to implement our program:

1. CWS is a 5-part, One Year, Eclectic Program for all Ages

Global Topics: Fluid Dynamics (3 months) & Sound (3 months)

Major Topic: Mighty Feathers & Birds (1 month)

The Big Project (1 month)

Books (Integrated throughout).

Use the two 3-month Printable Curriculums – available in 2 levels –  for Sound (SO) and Fluid Dynamics (FD) plus the one-month Printable Curriculum for Mighty Feathers (MF).  For the final month, do the Big Project described in the Printable Curriculum. Read suggested books throughout the program. You’ll have 32 to 36 weeks of science learning that the entire family can enjoy together!

Every year a new year of Science will be added.

2. CWS is Designed to be Eclectic

Eclectic means using the best of many options.  This is central to CrossWired Science.  All through the pre-university school years, students will be accessing many of the finest Science sources on the planet.

3. Using the Printable Curriculum is very easy.

There are currently three Printable curriculum components included in CWS: Mighty Feathers (MF), Sound (SO), and Fluid Dynamics (FD).  Each is available in 2 learning levels.

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 students finish CWS at the graduation of High School, they will have created  20 “Deep Science” notebooks in all. These provide a powerful reminder of God’s wonders!

The notebooks will be added to year after year. CWS will always be coming back to God’s wonders and deepening 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. Education Truths Governing 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 causes vast amounts of material that is 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 LEARN 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.  We understand the reasons for God’s design as we walk through life and His purposes for us.

Too much self-direction is a mistake.  

Don’t let teens (no matter how smart they appear) entirely steer their own science ship.  They need a captain who knows good 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 that there is tremendous joy learning science together.  The long-term family and educational benefits are HUGE


5. Ways to Customize CWS for Your Family


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 repetition of the greatest material. We’ve got this 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”–insertions which are heavily academic –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 greatly increase their academic, God-glorifying 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. Many parents find that 3 pages a sitting is good for “Youngers”.  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 detailed topics such as the amazing sonar of bats and dolphins.

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 printables for the “how to’s” and “when’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!
