Rating

In this electrochemistry activity, learners will explore two examples of electroplating. In Part 1, zinc from a galvanized nail (an iron nail which has been coated with zinc by dipping it in molten zinc) will be plated onto a copper penny. In Part 2, copper from a penny will be plated onto a nickel.

How Big is Small
Conditions of Use:

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water. This lab asks learners to record measurements and make calculations related to volume, diameter, area, and height. Learners also convert meters into nanometers. Includes teacher and student worksheets but lacks in depth procedure information. The author suggests educators search the web for more complete lab instructions.

Rating

In this activity, learners build bridges using paper and explore how much weight each bridge design can support. There is an element of surprise, which increases learners' interest in the physics, when they discover just how strong they can make this seemingly flimsy material. This lesson guide includes background information, discussion questions, demonstration ideas and extensions.

Plot the Dot
Conditions of Use:

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe. Learners then plot the data points on a large class graph of mass vs. volume to discover that data points for a particular material form a straight line, the slope of which gives the density of the material.

Sink or Swim?
Conditions of Use:

Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air. However, the sugar in regular sodas makes them denser than water so they sink. This is written as an exhibit, but can easily be adapted to become a demonstration or hands-on activity.
