Teen Tech Project: Building a Computer

Teen Tech Project: Building a Computer This week I visited with a homeschooling family whose son was anxiously awaiting his shipments from New Egg and Tiger Direct — full of the components he would assemble into his own PC. This brought back fond memories, since two of my three sons undertook this same project during their teen years, and my oldest actually did the same after he graduated. Read More »

Winter Warmup: Making Snowflakes

Winter Warmup: Making Snowflakes Snowflakes are fascinating to children and adults. They are unique, beautiful, and tiny marvels of nature. Introduce your children to the fun of cutting paper snowflakes. Instructables has step-by-step text instructions with photos and diagrams to show you how to make six-pointed snowflakes. Six-pointed flakes are the most authentic, since they generally occur in nature with six points. This YouTube video by The Bookhouse is a great paper snowflake-cutting demonstration that is easy to follow: Read More »

Instead of Curriculum: Electronic Circuit Boards

Instead of Curriculum: Electronic Circuit Boards Working with electronic circuit boards may sound ambitious or advanced, but my kids enjoyed playing with these as part of their science and technology learning when they were in their early elementary years. They learned many concepts about creating circuits from hands-on play, in particular by using a kid-friendly Snap Circuits® Kit from Elenco. Read More »

Interest-Based Groups For Learning & Fun

Interest-Based Groups For Learning & Fun In my family, interest-based groups have been an important part of homeschooling life. We formed a number of these groups over the years. Some, like a history club made up of eager parents and not-so-eager young children, barely lasted long enough for a few meetings. Others have lasted ten years. The most successful has been our boy’s science club. It was started by five families with nine boys between the ages of seven and eleven. When we began it was highly structured. We met regularly at each other’s homes. Parents took turns planning a project or experiment, got the materials, ... Read More »

Citizen Science

Citizen Science How YOU can get involved in real science! There is a new craze hitting the streets, and hopefully this one is here to stay. It’s called citizen science. With the advancement of technology, it has become easier and easier for “regular” people to do real science. There are people everywhere interested in contributing to science, especially if it’s made easy for them. With citizen science, it is. Not only do citizens collect and report data, but they are becoming valuable helpers in analyzing the vast amount of data that is now available due to increased technology. The best part is ...

Benefits of Homeschooling: Inquiry-Based Learning

Benefits of Homeschooling: Inquiry-Based Learning I recently wrote about how homeschooling parents can use a dialogue-based approach to education, which I see as a big potential benefit to home education. While many public schools have been forced into test-prep mania that defines success very narrowly, homeschoolers can use this educational approach to develop critical thinking and evaluate learning. Scientific American has a recent story that reflects my thoughts on the unfortunate increased emphasis on standardized testing in public education. Read More »

Get Ready for Spring with Field Guides

Get Ready for Spring with Field Guides A library of field guides is an important resource for homeschooling families, and with spring just around the corner, it’s a great time to make sure you have what you need on hand to help with identification of birds, trees, insects, spiders, snakes, turtles, frogs, toads, and wildflowers. Our field guides have always been among the most accessible books in our house. Rather than shelving them with other books, I usually keep them stacked — with their spines showing their titles — right on top of a low book shelf or table near the back door. Read More »

The Seasonal Table

The Seasonal Table Sometimes we have had a designated nature table, something which is suggested by both the Waldorf-inspired approach and the Montessori-inspired approach to homeschooling, and something many Charlotte Mason homeschoolers implement as well. Other times, we have just gathered seasonal treasures together as a kitchen table centerpiece. A walk in the brisk air, the scavenger hunt for natural objects that are lovely to see and touch and smell and shake, the artful arranging and rearranging of the bounty — these refresh the senses and clear the cobwebs out of minds.

Adam Steltzner: From Failing Geometry To NASA “Rock Star”

Adam Steltzner: From Failing Geometry To NASA "Rock Star" You may not have heard of Adam Steltzner at all, or if you watched the Curiosity rover’s landing on Mars you may know of him as “Elvis guy” at NASA’s Jet Propulsion Laboratory. He has a PhD in Engineer Physics, and the story of his rise to “rock star” status among millions of NASA fans is inspiring. He wasn’t a typical science nerd. Read More »

Please download or print the diagram of a microscope before starting this tutorial. Keep in mind that using a microscope is a skill. You may have to stop the procedure and start over several times before you find your specimen. Keep at ... Read More »

Spiders Are Our Teachers

Spiders Are Our Teachers We appreciate spiders in our family. A large orb weaver lives just outside the front door. Every night when we take the dogs out before going to bed we pause to appreciate the intricate web she’s rewoven. It has a lot to teach us about strength, symmetry, impermanence and beauty.

Easy Crystal Experiments

Crystals are formed with atoms line up in patterns and solidify. There are crystals everywhere – in the form of salt, sugar, sand, diamonds, quartz… and more! When making crystals, there is a very special kind of solution to make. It’s called a “super saturated solid solution”. What does that mean? Here’s an example: ... Read More »

Avoid the Biggest Mistakes When Teaching Science Part 3

… Continued from Page 2 Mistake #5. Fear of making mistakes. Honestly, now… when do you learn more?  When you make mistakes, or when you get it right?  And how many of us have a hard time letting our kids make mistakes? Edison made thousands of mistakes before he invented the light bulb. Or did he?  His “failures” resulted in the basis for the internal combustion engine, electrical wiring for your house, and hundreds of other things we use every day.  Remember that you always get to choose what something means to ...

Avoid the Biggest Mistakes When Teaching Science Part 2

… Continued from Page 1 Mistake #3. No space for the job. Once your child excited enough about something that they want to take it and run, your next task is to give them what they need! Now, kids need their own space. However, parents worldwide go crazy with the pack-rat syndrome kids seems to have.  Here’s a solution to make both parties happy. In a corner, set up a table that’s all theirs.  No touching.  This is for two important reasons: first, it’s a lesson in organization waiting to happen.  When they whine to you that they can’t find something, you can ...

Top Ten Air Pressure Experiments to Mystify Your Kids Using Stuff From Around the House

There’s air surrounding us everywhere, all at the same pressure of 14.7 psi (pounds per square inch). It’s the same force you feel on your skin whether you’re on the ceiling or the floor, under the bed or in the shower. An interesting thing happens when you change a pocket of air pressure – things start to move. This difference in pressure that causes movement is what creates winds, tornadoes, airplanes to fly, and some of the experiments we’re about to do right now. Read More »

Germ Warfare

Hand washing and safe food handling are very important to me. I’m not above bringing food safety brochures to potlucks. This fixation is not without cause, though; as a teenager, I contracted my first obvious food-borne illness after eating strawberries in Mexico City. During the space of the next few years, I had the educational experience of coming down with G.I. infections of Staph and Salmonella, also due to the unsafe food handling practices of others. And then, in my youth, I landed a job that required me to become a certified food service manager. It was during this training course ... Read More »
