In nearly every corner of the Earth, ants wage war against each other. Their weapons are what nature gave them. Some have strong armour, deadly stingers or sharp mandibles. And then there is this tiny, and not very impressive ant. But it rules the biggest empire any ant has ever built. A colony spanning continents and fighting wars that leave millions of casualties. Let’s take a look at this unlikely warrioress: Linepithema humile, the Argentine ant.

To understand the challenges of satellite construction, student teams design and create model spacecraft to protect vital components from the harsh conditions found on Mercury and Venus. They use slices of butter in plastic eggs to represent the internal data collection components of the spacecraft. To discover the strengths and weaknesses of their designs, they test their unique thermal protection systems in a planet simulation test box that provides higher temperature and pressure conditions.

Early Math on Khan Academy: Math begins with counting. It's the most important skill we learn in our early years and becomes the foundation for all other math concepts. Once we can count, we can add, subtract, and measure the world around us. Shortly thereafter, we can learn about place values, plots, graphs, time, money, and shapes. These early math skills are presented in this subject's tutorials in a straightforward, understandable, and (dare we say it) fun way!

This week, I revisited a project I've done in the past, a MaKey MaKey Ukulele. If you aren't familiar, MaKey MaKey is a little microcontroller board that sends keystrokes to a connected computer when you make various connections, so I hooked it up to copper tape on my ukulele and made a little visual accompaniment in Scratch.

Ten points if you catch the leopard reference.

Through a teacher-led class demo, students observe a simple water cycle model to better understand its role in pollutant transport. Using kitchen or lab equipment, the demo simulates a point source of pollution in a lake and the resulting environmental consequences—one way in which pollution is affected by the water cycle. A student worksheet is provided.

Someone asked me a while back to make a video on simple sentences. I hadn’t thought of how tricky that might be to some. As a learner, I always thought of Spanish as a code. Maybe this code will help you as well!

Basically it involves a subject and a verb. And we can also add some other things to the sentence. In this video we’ll talk about one of those things: conjunctions and give some examples.

Please like the video and share with others who could benefit. More Spanish lessons coming.

Request a topic you’d like for me to go over in a future video!

Students move through the engineering design process as they write Arduino code and use a “digital sandbox” to create new colors out of the three programming primary colors: green, red and blue. They develop their own functions, use them to make disco light shows, and vary the pattern and colors of their shows. The digital sandbox is a hardware and software learning platform powered by a microcontroller that can interact with real-world inputs like light, while at the same time controlling LEDs and other outputs.
