Exploring Size: Scented Solutions
Source Institutions
This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).
Team Up: Fun With Division
Source Institutions
In this activity, learners will divide into teams or groups of equal size. “How many teams of three can we make?” “We need an equal number of children at each of the four computers.
Globby Gooey Gak
Source Institutions
In this activity, learners concoct some stretchy green goo called Gak. This activity will introduce learners to polymers, chemical reactions, and how scientists invent new materials.
