Homework First

Homework First is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Homework First rather than just read about it. In short: The Homework First is a combination lock parental control device for the Nintendo Entertainment System made by SafeCare Products, Inc. of Dundee, Illinois and Master Lock. The lock features a "Self-Setting" combination that attaches to the open bay of a front-loading NES-001 system via a screw hole below the cartridge slot which enables the lock to grab the console like a vise to prevent both the insertion of cartri…

Key takeaways

Homework First belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Homework First to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Homework First from memory before moving on to harder problems.

Reference excerpt

The Homework First is a combination lock parental control device for the Nintendo Entertainment System made by SafeCare Products, Inc. of Dundee, Illinois and Master Lock. The lock features a "Self-Setting" combination that attaches to the open bay of a front-loading NES-001 system via a screw hole below the cartridge slot which enables the lock to grab the console like a vise to prevent both the insertion of cartridges and the removal of the device. Around 25,000 units were claimed to have been sold.

Reception ACE magazine panned the device on a conceptual level during their 1989 CES coverage. Jeuxvideo.com cited the device as one of the first video game parental controls.

Worked examples

Example 1 — a first encounter with Homework First

Start with the simplest possible case. Write down what Homework First claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Homework First before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Homework First ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Homework First

In research: Homework First appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Homework First in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Homework First is common in secondary-school and first-year university syllabi. It links to neighbouring topics Locks (security device), Nintendo Entertainment System accessories, Video game hardware stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Homework First outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
