Science and Carpets

November 28, 2021 by NZ Filbruns Leave a Comment

I started going through a new science textbook with my three schoolchildren in October (sure seems strange to only have three in school! Technically, there are four, but Mr. Diligence is now working almost all the time, since he turned 16.). We are working through Exploring Creation with Chemistry and Physics, from Apologia. I’m finding it quite interesting. I think I may have done some chemistry in high school, but I really don’t remember for sure—and if I did, I don’t remember it! The children are struggling to understand what we’re learning and to enjoy it, but they love the experiments!

This experiment was to show how substances of different densities react. We mixed differing amounts of salt into these cups of water, and then put some into a straw. It was a lot of fun to figure out how to do this.

One jar held salt water, the other plain water—the egg floated in one of them.

What things float and what things sink?

Each of the children got to fashion a boat from a piece of foil. Which ones would hold up the most coins?

Mr. Sweetie was the winner! He shaped his foil over a bowl.

Elijah is enjoying his apprenticeship as a floor layer. One job he did a couple of weeks ago was to lay carpet tiles in the dining room/lobby of a seven-story hotel in Greymouth. He was given this diagram to follow. It is supposed to symbolize the Grey River, the sea, and the mountains. I was in town several days later, while he was working on the upper floors, and stopped in so I could see this amazing floor. It was still under plastic to protect it while renovations continue, but even so I could tell it is beautiful!

Here is a picture Elijah took from an upper floor. What a view! That is the Grey River, emptying into the sea in the distance.

Product Review—CrossWired Science

April 17, 2019 by NZ Filbruns 2 Comments

I wasn’t overly excited about reviewing CrossWired Science when the opportunity was presented, but we watched all the sample videos before I made the final decision, with input from my four school boys. We all agreed that the videos were fascinating—and one of them answered a question I had vaguely wondered about before (how do animals get their Vitamin D?). We decided to request this online program for review and give it a try. Am I ever glad we did! I am loving it! The children are enjoying it, as well, some more than others.

We have been given access to both of the global topics that CrossWired Science has come out with so far, Sound, and Fluid Dynamics. So far, we have mainly focused on Fluid Dynamics, since the majority vote from the boys was for that one, although I would like to go through Sound as well. It has been fascinating to learn about how air and water work. We have watched videos on a number of subjects that all have to do with air and water movement. For example, one was about Dog Slobs & Cats. It showed, in great detail, how both animals lap water and why dogs make a mess while cats are tidier (although our cat manages to splash milk all around her dish, somehow). After we watched that, Mr. Imagination checked out our cats’ tongues to confirm that they have the texture that the video said they did. Other videos talked about dolphins, boxfish, penguins, nose aerodynamics (now we know why our cats are so lazy!), carburretors, and the alulas on bird wings (another lifelong mystery cleared up for me), among other topics. Each video has a worksheet with questions from the video, as well as a true/false online quiz. We have not done any of these worksheets, because they were not available when we started the course, but have done the quizzes. There were a few discrepancies between the quizzes and the videos; this is a brand-new course and is a work in progress, so I expect to see these problems resolved soon. (It’s very good already, but once these issues we noticed are corrected, I believe this site will be great.)

Besides the videos, there are many other suggested activities. There are a lot of options for experiments. I somehow neglected to get any pictures of my boys trying out the matchhead rockets, but they spent several days playing around with them. They had loads of fun building and shooting off these miniature rockets, and Mr. Intellectual discovered a new-to-us YouTube channel full of fun experiments (I think it includes a fair number of explosions, which he loves!). They also tried out the paper airplanes and figured out how to make a loop of paper fly very well across the room.

One page suggests many books to read. We have a few of them, so we added them into our read-aloud day. I was happy to be reminded to read The Great Dinosaur Mystery and Dry Bones and Other Fossils with my boys. The wide range of books that are recommended would make a great library. They suggest several biographies by Janet & Geoff Benge, one of which (Alan Shepard) we read in the past year. They also recommend Creation magazine, so I told Mr. Intellectual to spend his science time one day summarizing what he had been telling us about from the most recent issue the day before.

Right now, we’re working our way through the Gold Dig section. This is six pages about bones. The first page had a video and a quiz; we’re currently on the next page, which talks about all sorts of subtopics having to do with bones—just look at this outline!

There is a worksheet which goes along with this. Each day, I’m reading through about three sections of this page with Mr. Diligence, Mr. Sweetie, and Mr. Imagination, and we answer the questions that go along with those sections. It takes about 15 minutes to do that much, and that’s about all the time they can handle doing something like this, since we usually don’t get to it till after lunch and they are ready to run outside! Mr. Intellectual is doing this part by himself, since he is a strong reader. One thing we really enjoyed about this page was a photo of the International Space Station. What we really loved was that New Zealand, and the top part of our island, was in the background! It’s a very clear photo, and we could almost see where we used to live!

I’m also looking forward to learning about sound. So far, all we have done there is to watch one video, which was about the larynx and the vocal cords. It looks like the Global Topic on Sound is laid out similarly to the one we’re working on. All the Digging Deeper pages have something to do with sound, in humans as well as the animal world. We had started the year using the same series of science textbooks we’ve been using and loving for the past several years, but I’m thinking we’re going to finish what we want to use in CrossWired Science before we go back and finish that book. There is so much to love in this course! We’re enjoying the variety of ways to learn about the topic, and we love the way it points to the Creator. One thing we’ve noticed is that the videos don’t actually mention God, but what we read on the screen does. The videos do talk about how things are designed to work the way they do, very definitely giving glory to God if you think about it a little. I am very slow to buy an online program for school, but this is one that is worth the price they ask for it, even for us. I like it and am very glad we were put on the review.

If you are interested in trying out this fascinating website, here is a coupon code that will take $5 off every order—no matter how many times it is used: loh12.

One thing I had a bit of trouble figuring out is how to schedule CrossWired Science. There is so much information here, in a variety of styles, but it’s not laid out in lessons, although I have heard that there is a suggested schedule somewhere on the website—I haven’t found it myself. The intention is that a student will choose what appeals to him, and work through most or all of each project (Fluid Dynamics is one project) in any order. The way it’s set up, you click a button labeled “Finish Quiz” at the bottom of each page, and then you can tell by looking at a bar at the top of each page how many more pages there are to complete. All ages can do this course together. Of course, older children will go more in-depth than younger ones, but even Little Miss, who is four, enjoys the videos. Also, there are two levels. We’re using the First-Timer course, but for those who have been through it once as a younger child, they can do it again using the Second-Timer course. I haven’t looked at it yet, so I can’t say how it is different. Here are screenshots of the menu on the Lesson Page. You can see that they have made it easy to tell which lessons are completed.

Each project is intended to be a full Science curriculum for a month or two. The plan is to have enough projects up to provide six years of Science! I’ll be very interested in following the progress of this course to see how it develops. Of course, not only can it be used as a stand-alone curriculum, it could also be used as a supplement to any other science curriculum. Be sure to click on the banner below to see what the rest of the 80 reviewers have to say—I’ll be checking out some of those reviews, because I’m curious to know what others think of this!

Book Review—Exploring Creation With Astronomy

December 6, 2017 by NZ Filbruns Leave a Comment

We just finished science for the 2017 school year. This is the fourth year in a row that we have used Apologia’s Elementary science, and we’re still loving it. This year, we used Exploring Creation With Astronomy. I thought Jeanne Fulbright wrote great books before—but in this 2^nd Edition she outdid herself! This was a very fascinating course. I’m glad I decided to buy the new book instead of borrowing the old one from a friend.

Since our school year began in February, we have traveled through the solar system and beyond. We began with a quick overview of astronomy and the solar system, and then took more in-depth looks at the Sun and each planet, as well as the moon. There was also a chapter on Space Rocks, tucked in between Mars and Jupiter. The section about the Asteroid Belt was especially fascinating to me; the hypothesis presented for the existence of the asteroids sure made sense to us! The second-to-last chapter was also very fascinating for me, as it presented information that has been discovered recently, so it was all new for me. I think it’s rather sad that Pluto has been downgraded to a dwarf planet, but it was very interesting to learn about such things. The Kuiper Belt, too, was new to me—and so interesting! The last chapter talked about stars and space travel.

As we have done before, I bought the notebooking journals to use with the textbook. We get a lot more out of the course by using these workbooks. Every day as we read, the boys narrate a sentence or two (or more, if they enjoyed the section) about what they learned, and there are activities to do as you go through each of the chapters. Each chapter has anywhere from one to three minibooks to make, to help with review, and there is also a vocabulary activity. We liked the way the 2^nd edition notebooking journal was laid out much better than the others we have used. Instead of having to find the pages for the minibooks in the back, they were right in each lesson, where we needed them. Also, these activities were interspersed with other things in the lesson, rather than always at the end. The book was a bit more attractive, too.

We didn’t do all the activities, but some that we did were great fun. Probably the most memorable was the time we made a “scale model” of the distances in the solar system if the sun were the size of a dime—so incredible!

As always, I highly recommend Apologia’s science! We love that God and His Word are honored all the way through, and we enjoy the very interesting way in which facts are presented.

You can see pictures of a couple of our projects from this course here and here.

Book Review—Exploring Creation with Zoology 2: Swimming Creatures of the Fifth Day

December 26, 2016 by NZ Filbruns Leave a Comment

We have finally finished our science course for the year. It was very hard to get in time for science this year, with the crazy schedules we had all year, and a lot of time off school for one reason or another. Toward the end of the year, after several of the boys finished some subjects and I had more time, we were able to do lessons more often. I have thoroughly enjoyed our study this year, of Swimming Creatures of the Fifth Day. I am greatly enjoying getting an in-depth look at various topics from a strongly Christian, Creationist point of view. Jeannie K. Fulbright has done an excellent job with this book, as with the other books we’ve used that she wrote.

Because this review has now been published on Esther’s website, I’ve removed the rest of it. Read my full review here.

Exploring Creation With Zoology 1: Flying Creatures of the Fifth Day–book review

This year, we used Zoology 1. Here is the review I just finished writing of it.

I wrote a long review for this book, but it has now been posted on Esther’s website, so, in order not to mess up her SEO (Search Engine Optimization–I’m learning all sorts of jargon from her!) I’ve removed it from here. Please go here to read my review now. Thank you!

Exploring Creation With Human Anatomy and Physiology–book review

Sometime last year, I wrote a post about this book, but I decided to share the review I just finished writing of it here anyway. I love Apologia!

Fossil Hunting

June 13, 2012 by NZ Filbruns Leave a Comment

Yesterday at our homeschool writing group meeting, a man showed us a powerpoint presentation about fossils. He has been collecting fossils for several years and has an impressive collection from the local area. My boys badly wanted to go to Gore Bay and search for fossils along the cliffs there, so, since it was sunny and warm today, we went right after lunch. When we arrived, the tide was high, with waves hitting the cliffs, so we sat on top and read some of our books for school before we went down. The tide was still so high that we couldn’t get to the best places, but the boys climbed up some of the less-vertical cliffs anyway. We never found anything that we were sure was a fossil today, but had fun exploring anyway. One unusual thing we saw was an oystercatcher (bird) with a missing foot! I could tell something was strange about it, and when I was able to see its tracks, it had one normal footprint and one that was just a round peg. Poor thing.

The tide when we arrived.

Reading stories.

This one quickly got bored with the stories and found something more interesting! Climbing the cliff to hunt for fossils

After they gave up on fossils, they cut a few branches of lupine bushes.

Driftwood makes a great boat.

The tide when we left–quite a ways farther out, and notice the shadows. Short days right now.

And these two pictures are just because they’re cute! The first one was this morning when 2-year-old needed something to do during school and I assigned him to “read” to baby.

This one was after we got home this afternoon. I set baby on the couch while I went to do something else, and when I came back he was staring, fascinated, at his booties! They kept wiggling!
