6.890 Algorithmic Lower Bounds: Fun with Hardness Proofs is a class taking a practical approach to proving problems can't be solved efficiently (in polynomial time and assuming standard complexity-theoretic assumptions like P ≠ NP). The class focuses on reductions and techniques for proving problems are computationally hard for a variety of complexity classes. Along the way, the class will create many interesting gadgets, learn many hardness proof styles, explore the connection between games and computation, survey several important problems and complexity classes, and crush hopes and dreams (for fast optimal solutions).

Farming ants might sound like a crazy thing to do unless you might like to eat chocolate covered ants. It turns out we can learn a lot from ants and the best way is to build your own ant farm.

A very basic introduction to solving the Rubik's Cube.This is part of a demonstration of various design features that can improve learning. This version has none of those features! It's just text, so it would presumably be very difficult to learn from it.I hit some (secret) limit on the number of characters in the description, so I couldn't include the learning objectives. I'll put them in the first section instead. 

All living beings are made up of cells. Some of them are made up of only one cell and others have many cells. Also in: Dutch | French | Hungarian | Spanish

What is cloning and do we have clones living among us today? The answers might surprise you or maybe we should say ewe.

There are several different ways to get ants for an ant farm, depending on when you would like to start the farm and how long you would like for your ant farm to last.

A favorite movie, “E.T. the Extra-Terrestrial,” provides the backdrop scenario for students to discover how harnessing the sun’s energy provides unlimited power for many purposes, including the operation of thousands of satellites in orbit today and communication over long distances. In the movie, E.T., an alien life form, is stranded on Earth and befriends Elliott, the little boy who rescues him. As E.T. becomes gravely ill, Elliott realizes that E.T. needs to return home in order to survive. To arrange for transport, E.T. must “phone home.” Teams engage in an interactive quest to answer the question: E.T. phone home—fact or fiction? They must discover four clues in order to unlock four padlocks on a box that contains the answer. This requires them to watch a one-minute online video, complete a crossword puzzle, scan three QR codes for articles to read, and put together a cut-apart puzzle with an invisible ink clue. They watch short online movie excerpt videos to kick off and wrap up the activity.

Imagine being the size of an ant. Be careful - a face-to-face encounter with an ant would be scary and potentially life-threatening! But, if you avoided being eaten, you could learn a lot about ant anatomy from a close-up view. Ants have many body parts that are normally hard to see without a magnifying glass or microscope. And each structure has its own special function.

Almost everyone has wished at one time or another to be able to fly like a bird. Just the thought of soaring above your city or town without any mechanical device gives us a reason to envy these feathered animals. Also in: French | Spanish

This material contains 5 incomplete tongue twisters.Student will complete each line by adding the same letter. Students practice saying the tongue twisters in pairs and/or with the instructor. Second activity has fishing vocabulary with missing first and last letters and matching definitions.

A picture book for grades 2-5. Tells the story of a lonely fox who lives on an island and decides to grow a garden. He is initially frightened of a bee who comes to the garden, but eventually learns of the bee's usefulness and they become friends. Inside the illustrations are a series of rebuses that, when decoded, tell the story of how bees pollinate flowers and make honey. Decoding the rebuses teaches students not only the ecological functions of bees, but also the mathematical principles of PEDMAS/BODMAS.

This course provides practical instruction in the design and analysis of non-digital games. Students cover the texts, tools, references and historical context to analyze and compare game designs across a variety of genres, including sports, game shows, games of chance, card games, schoolyard games, board games, and role–playing games. In teams, students design, develop, and thoroughly test their original games to understand the interaction and evolution of game rules. Students taking the graduate version complete additional assignments.

While cannibalism is fairly common among insects and crustaceans, most backboned animals avoid feeding on their own kind.

Every living thing must be able to reproduce and make offspring. Most of us are familiar with how humans and mammals make babies, but do all creatures reproduce in the same way? Do insects, like the beetle, give birth to little insects? Also in: French | Spanish

Searching for things on the Internet can be like hunting for a needle in a large haystack. Just how large is the Internet?

We hear the word ecosystems in the news and at school but just what are ecosystems? It turns out there are lots of ecosystems. You might even learn you have some inside you! Also in: French | Spanish

Biologists at Arizona State University hope that by learning more about animal behavior, they will also be able to understand why people act the way they do.

Thousands of orange and black shapes flutter through the trees. Welcome to one of the few wintering homes of the monarch butterfly. Also in: Spanish

A very basic introduction to solving the Rubik's Cube.This is part of a demonstration of various design features that can improve learning. This version has only one of those features: the Multimedia Principle (Clark and Mayer, 2016). It's a little better than text-only, but not a lot.
