- Summary
- This animation illustrates the negative powers of ten. Starting with one meter, we delve successively into matter until we reach objects in the range of a nanometer.
A correspondence between exponential notation and units of measurement (millimeter, micrometer, nanometer, angstrom) is demonstrated.
- Learning objectives
- To illustrate the structure of living cells and orders of magnitude.
- To introduce the problem of units and orders of magnitude.
- To define the powers of ten (in this case, the negative ones)
- To define the terms decimeter, millimeter, micron or micrometer, nanometer and angstrom.
- How to use the animation
- Click on the central frame or on the scale at top to progress through the zooming process.
