Function machine (grades 6-8)
Applying a machine metaphor for functions, this virtual manipulative allows the learner to examine the relationship between input (domain) and output (range). The learner inputs numbers from one to four and the virtual machine generates output information in a table. The learner is challenged to find the output for values five through seven and enter them in the table. Errors are noted automatically. Using a new function button, different types of functions are randomly offered for investigation
Your sense of smell
This single-page resource about the sense of smell presents a handful of facts about smell together with scientific illustrations. For example, the resource points out how many odors humans can detect and what scientists still do not know about smell. It also compares our sense of smell to that of rodents. The scientific illustrations are a set of connected, labeled diagrams of the key structures and pathways involved in sensing smell, including the olfactory membrane and olfactory receptors. Th
