The Heinemann Science Series

I really love the Heinemann “InfoSearch” science series; unfortunately, the books are no longer in print. You might be able to pick up some of them used, though, as through Amazon or eBay.

Each book is 32 pages and filled with solid information, simple experiments, and historical context. The pages are laid out nicely in full color.

If I find another in-print series I like as well I’ll write about it; for now I feel fortunate that I was able to collect ten books from this series. My five-year-old loves them.

A Pocket LED Microscope Is an Amazing Learning Tool

The Carson LED pocket microscope is, for the money (less than $14), the single-best science tool I’ve purchased (available on Amazon—paid link). After using a clunky old microscope with a mirror, the new microscope is a dream. I popped in a AA battery to power the light and immediately got great results. It “only” offers 120x magnification, but for kid use it’s perfect. Plus it’s cheap enough that I won’t worry about it getting broken, so it will be great for backyard and camping use.

Fun with Magnets and Electricity

Magnetism and electricity are strange and amazing forces. How can one object act on another object at a distance without any apparent intermediary contact? If I blow a piece of paper, I act on the paper via the breeze I create. But magnets do surprising and nonintuitive things. Although young children are not ready for the full theoretical basis of electromagnetism (I’m not even ready for the full basis), with some basic supplies they can explore how magnets and electricity operate in the world.

Parasitism in Nature

If you’re looking for a creepy science lesson, check out parasitism in nature.

There’s a type of fungus that takes over an ant and causes the ant to crawl up a branch and latch on, where the fungus grows and spreads. Different types of fungus can attack different animals.

Wikipedia has an entry. The Atlantic and National Geographic also have articles.

National Geographic has a short video about this.

One-Off Science Videos

Elsewhere I’ve discussed some science video programs that my child and I really like. Here I want to list some fun one-off science videos we’ve found. (I’ll update this page over time.)

Bats and White Nose Syndrome
This article and Ted Ed video discusses a fungus that attacks bats in North America. The video is more general.

How a Piston Works
The piston in a gasoline engine is a wonderful example of the conversion of chemical energy to motion. Good videos on this include those from Toyota of Orlando, Automotive Basics, and Yasha Verma.

The History of Steel
Jason Crawford gives an hour talk on the subject.

A Five-Minute History of Concrete
Jason Crawford gives a great five-minute history of concrete (embedded in a longer video; I’m included the appropriate time stamp for the start point).

How to Make Charcoal
This is a really fun video by Primitive Technology, via Jason Crawford.

Parasitism in Nature
I collected a variety of videos on this.

Great Science Video Series

Like many parents, I have struggled with how much screen time to allow my child. What I’ve settled on is tightly limiting “junk” TV and videos but allowing moderate amounts of quality videos. At this point I do not merely tolerate screen time; I actively welcome it as an important contribution to my child’s education. Here I want to briefly review several high-quality science series that my five-year-old absolutely loves.

Mystery Doug

Mystery Doug is a series of over a hundred science videos produced by Doug Peltz and the team at Mystery Science. The videos are available at no charge through YouTube and Mystery Science’s web site. When viewed through the web site, which (I think) requires free registration, the core videos accompany supplementary materials.

Core Knowledge Free Materials for Grades 1 to 8

As discussed in my posts on preschool and kindergarten materials, Core Knowledge offers an enormous amount of educational materials for preschool through eighth grade.

I’m going to provide fewer links for the material for grades 1–8 than I did for preschool and kindergarten. I’ll still walk you through the material and link to the student readers that I find valuable.

Core Knowledge Free Kindergarten Materials

I’m a big fan of Core Knowledge’s dozens of student readers, free as pdf downloads. But the materials are harder to use (at least for homeschoolers) at the preschool and kindergarten levels. Earlier I compiled relevant preschool materials; see my related post. Here I’ll walk you through the kindergarten materials and include relevant links to Core Knowledge. See also my most on materials for grades 1–8.

Core Knowledge Free Preschool Activities

You may be aware of Core Knowledge, the educational program started by E. D. Hirsch Jr. Various charter schools, for example, base their programs on Core Knowledge (not to be confused with Common Core). And you may be aware that Core Knowledge offers an enormous amount of K-8 learning materials online at no cost to the user.

Last year I started downloading the student readers in pdf form. Volumes cover history (such as Ancient Greece and Rome), science, and literature. These are amazing resources especially for homeschooling families on a budget. I have an old Kindle reader (the kind with the button keyboard) dedicated to such educational books.

What I didn’t realize until recently is that the preschool level offer a lot of great material presented as “activity pages” rather than as “readers.” These offer content for parents to read with their children as well as simple activities.
