This is a very fun lab that investigates two factors which affect the rate of a reaction: temperature and surface area. Originally intended for Regents Chemistry, but can easily be adapted for middle school science or Physics.
Students are able to deduce the definition of elements, compounds, and mixtures using models provided. This is a concrete way for students to understand how matter is classified. Intended for a Regents Chemistry class activity, but is easily
This is a fun lab on finding the density of liquids. Students determine the densities of a sugared soda and its diet equivalent in order to identify the "unknown" liquid based on density. Geared toward a Regents Chemistry class, however, it can
