In addition to the engaging and interactive online content, students will download and create self-guided Science Notebooks. Combine all of this with the suggested reading and hands-on experiments to create one of the most fascinating, delightful and innovative science programs ever!


students of the One Year program

Log in with your student account.

  1. Download one of the 3 Printables for CrossWired Science (CWS) – Sound (SO) or Fluid Dynamics (FD) or Mighty Feathers (MF). We suggest starting with Fluid Dynamics. (Mighty Feathers (a study on Birds) is an abbreviated “Major Topic” not a full “Global Topic” like Sound and Fluid Dynamics.)

    These may be found in each Topic Area. To get to the Topic Area, go to the Curriculum button in the top menu bar and select one of the 3 topics. Click to go in and the Printables will be there.

    Each day you can go into the topic area through the “Curriculum “ button in the top menu.

  2. Chose the First Timers or Second Timers Level. The “Global Topics” Sound and Fluid Dynamics have a beginner level for most students K-9 called “First Timers” and a more advanced level called “Second Timers”.

    We suggest that every student including Biology students start with First Timers–unless the student has significant background in science.  There are a few sections for the “littles” but First Timers is generally the way to begin using CWS.

  3. Print the printable if you desire to make a notebook. (You do not need to. You may cover many parts by completing work on-line and may make a notebook and place assignments there. We love the printables so we suggest printing your first one to try it out.

    We recommend making this a life-time notebook and using a nice notebook which has a place for the printed color cover. Staples has excellent notebooks for this.

  4. Begin covering the material day-by-day. 

    All links can be accessed by clicking the downloaded copy of the printable on your tablet or computer. All directions for each area are on the Printable and also in the area to be addressed.

    You can follow the days as listed in the Printable or skip around if your parent or teacher wants to switch the order. This is fine.

    Clickable Youtube links are found in the Teacher user. These do not have YouTube commercials.

Students using CrossWired as a Supplement

  1. Download the 3 Printables as described above and follow the directions above.
  2. We have a number of suggested calendars in the top menu item “Calendars”. Print which one you desire to follow or fill in one of the blank calendars found there.

Parent & Teacher Directions:

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 Printable has full directions for the year. (You may use the worksheets in lessons or skip these.)

  2. There is background information in the top menu bar under the topics: FAQ’s, Ed Why’s and Blog.

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

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

  5. Clickable Youtube links are found here. These do not have YouTube commercials.

"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!
