Class prep · TJ Bionanotechnology

See the small scale,then judge the claim.

An independent course in bionanotechnology. Connect size, forces, and biological machines, and say in words what a result does and does not show. Every problem has a full worked solution. Built by Neil Kothari, a TJ alumnus.

Lesson 1.1: Nanometers, Cells and Atoms on One Scale

Convert among meters, micrometers, and nanometers before you compare a cell, a protein, and a device feature.

Start with one ruler for a protein, a cell, and a length in micrometers. Convert the unit, then say what the number does and does not show.

Problem 2

Core
True or false
No calculator
2 pts

True or False: One micrometer and one nanometer are the same length written two ways, using the model in this lesson (1\,\mu\mathrm{m} = 1000\,\mathrm{nm} = 10^{-6}\,\mathrm{m}). Justify your answer.

Problem 3

Core
Multiple choice
No calculator
4 pts

Which choice correctly names the largest model output among inputs 1, 2, and 5 um? Use the lesson model only.

How it works

Class prep that works alongside class

A complete bionanotechnology course for students taking the semester elective. Work alongside your school course or study the material in sequence. Each lesson starts from a concrete picture, develops the model, and shows the limit of the claim before you try the practice.

Original problems in several formats: true or false, multiple choice, multi-part and free response.
Each one is marked core, test level or beyond.
Scale, close-range forces, biological machines, self-assembly, and DNA used as a material, always with an exact calculation.
A worked answer for every problem, ending with the mistake that most often costs points.
Nanoparticles, sensors, gecko-inspired surfaces, and a written conclusion that stays inside the evidence.

Who built it

Neil Kothari

TJHSST alumnus · Co-founder, EduAvenues · 10+ years in TJ preparation

Neil is a TJ alumnus and has spent more than a decade working with TJ students and their families. He built this course so students can compute a fit exactly and then say what that fit does not identify. Every problem is written for the course and every answer is checked before it goes in.
