YouTube and Homeschooling

Does anyone else remember the animated science show on PBS called Eureka? Well, it is probably not surprising that bother NerdDad and I loved this show as kids. So NerdDad set to searching this out for the Nerdlings and Eureka! he found them. There are 30 pieces of episodes over at YouTube. We have downloaded them and uploaded them to the Tivo. NerdBug and NerdPie are loving them. They may not understand all the complex science but they ask to watch them over and over. So I am sure that the science will sink in! So I don’t know who BubbleBear83 is but I appreciate the effort. Now that is using the Internet to our advantage!

Gravity is a Mystery

I was picking up some books at the library a couple of weeks ago and Gravity Is a Mystery grabbed my attention. This isn’t a planned area of study for the NerdBug but hey, I love science and it looked fun. Now I am in love;). This book has the perfect balance of child friendly wording, illustrations and touching on actual full concepts. For example it gave the actual formula for Universal Gravitation, the actual explanation of the formula and then had a child like explanation. The more advanced explanation is separate from the “book” so you can avoid it if you would like. The illustrations are colorful and helpful to concept understanding. What is really cool is that Branley has written a variety of other books. So he may become the NerdFamily’s favorite author!

Jumping Kangaroos and Red Foxes

So today I am reviewing 2 animal books that are both by Michelle Levine. The NerdBug (1st grade) read Jumping Kangaroos to his siblings and myself today. They all loved it! It had the right combination of easy words and words that needed to be sounded(like marsupials and pouch). This can also be said of another of Levine’s books, Red Foxes. The information in both books is great. It has great individual facts that can mesh to a more complex development but also stand alone as facts. That is great for my 6 and 4 year old because it seems that the individual facts are what they glom onto at this age (as is fitting in the classical model;). I will be looking for more books by this author for my kids to read so I highly recommend it!

Ants

We have had another great science book. The kids and I just finished reading Ants (Early Bird Nature Books) and they loved it. It starts with a list of words to look out for and later defines them in the glossary. We used the list as a built in list of review questions. It does have some difficult and unfamiliar words (such as thorax and larva) so while most words are simple enough for a first grader, I would have them read it close so you can help with those words. We just read is aloud with the 6, 4, and 2 year old. It has great pictures and diagrams. We will be requesting the rest of the books in this series from the library.

Aqua Dots Kill!

While that may sound like an inflammatory title it is true. The AquaDots toy was made with substandard chemicals that turn into a date rape job when activated by water. (Those with toddlers read when eaten.) This can lead to come, seizures and possibly death.

Chemically what is going on is:

The toys were supposed to use 1,5-pentanediol, a nontoxic compound found in glue, but instead contained the harmful 1,4-butanediol, which is widely used in cleaners and plastics.

The Chinese online trading platform ChemNet China lists the price of 1,4 butanediol at between about $1,350-$2,800 per metric ton, while the price for 1,5-pentanediol is about $9,700 per metric ton.

What I find especially scary is that I was looking at buying these Wednesday morning at SuperWalmart and didn’t get them because I was waiting for a sale.

Sloths: A Carolrhoda Nature Watch Book

In doing science we have recently checked out a book on sloths simply called Sloths (Nature Watch) by Melissa Stewart. This book was horrible. To kick off our unit on an animal I read a 1 page summary on them and then we get an additional book. Well, this book took each little fact and made pages on it, pages I said. Now I am not saying they enriched the material on it or went further in detail. They simply took 1 fact and drug out the wording to take a page. So first strike it wasted words. Second strike is it bored you to death doing it. The we get to decide to embark upon the ice age and evolution. On the whole I strongly disliked this book and will not be using it when my other kids do sloths in the future.

Four minutes to a nerdier you!

Here at the nerdFamily blog, we like to celebrate all things nerdy. And believe me when I tell you that there isn’t a scientific subject more nerdy than string theory. (It’s nerdier than quantum physics and non-Euclidean geometry combined!) And so, we present Discover Magazine’s pick, and viewers’ pick for best String Theory in Two Minutes or Less video:

Their pick – String Ducky:

Viewers’ pick – The Problem with Math:

You are now significantly nerdier than you were four minutes ago. You’re welcome.

Nature’s Children: Armadillos

I checked out Armadillos(Nature’s Children series) for a unit in Science for my 1st grader and my preschooler and I loved it. It is 48 pages (including the index) so it is substantial enough to have a good reading time. It has many sections that elaborate on specific points that were briefly mentioned in the The Kingfisher First Animal Encyclopedia (Kingfisher First Reference) chapter. My first grader could read many of the words but still needed some guidance but it is not real juvenile so one could use it probably in higher grades also. This is a book I will use again with other children.
