At its core, the LEGO MINDSTORMS(TM) NXT product provides a programmable microprocessor. Students use the NXT processor to simulate an experiment involving thousands of uniformly random points placed within a unit square. Using the underlying geometry of the experimental model, as well as the geometric definition of the constant π (pi), students form an empirical ratio of areas to estimate a numerical value of π. Although typically used for numerical integration of irregular shapes, in this activity, students use a Monte Carlo simulation to estimate a common but rather complex analytical form the numerical value of the most famous irrational number, π.

This lesson begins with an activity in which students induce EMF in a coil of wire using magnetic fields. Then, demonstrations on Eddy currents show how a magnetic field can slow magnets just as Eddy currents are used to slow large trains. There is then a demonstration in which a loop "jumps" because of a changing magnetic field. Finally, formal lecture reviews the cross product with respect to magnetic force and introduces magnetic flux, Faraday's law of Induction, Lenz's Law, Eddy currents, motional EMF and Induced EMF.

More than 2,000 years ago there was likely a thriving Taino community in the heart of Charlotte Amalie. In 2013 contractors began turning up shards of pottery and other artifacts during otherwise routine roadwork on Main Street near Market Square. Work was temporarily halted and archeologists were called in to help dig up what was described as a “major” find. Thousands of artifacts were eventually discovered in a relatively small area. A short documentary was later produced about the dig and the many interesting objects found on site. - - US Virgin Islands DPNR and the State Office of Historic Preservation

Similar to how Charlotte uses her web to communicate, students create webs for short messages. They learn how spiders create their webs, and about the different types of webs they make. With this knowledge, students design and create their own webs and incorporate messages.

This overview by CoSN delves into the facts and myths of AI: "If you've had time to pay attention, you may have picked up on the noise happening in K-12 circles around ChatGPT and the myriad of other AI web tools that suddenly are in the spotlight. Why all the noise and how do EdTech minded administrators respond?"

This lesson centers around the How AI Works: Chatbots and Large Language Models video from the How AI Works video series. Watch this video first before exploring the lesson plan.
Large Language Models (LLMs) generate new text. The text LLMs generate looks like a human might have written it because large language models are built based on large bodies of text, such as Wikipedia. In this lesson, students learn what an LLM is and how it works, then use an LLM to co-create a text with AI. Finally, the class wraps up with a discussion about whether or not LLMs are intelligent or creative.
This lesson can be taught on its own, or as part of a 7-lesson sequence on How AI Works. Duration: 45 minutes
