Weight and temperature

This morning we looked into measuring weight and temperature. Some of the things we focused on were Net weight, Gross weight, Fahrenheit compared to Celsius, estimation, conversion between grams and kilograms, and how to use thermometers. Estimation was especially interesting. Unless you have used measured weight a lot, it is hard to estimate. The students estimated how many pens would weigh the same as a stapler, as well as how heavy a feather or a Boeing 747 (333 - 440 tonne) would be. Here are a few pictures of our learning.
