Float or Sink?
Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...
Curated OER
Lead and Mercury Ion Catalase Inhibition
Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.
Curated OER
Fingerprinting Lab
High schoolers recover latent prints by iodine fuming, cyanoacrylate fuming, and dusting with powder, after a lecture/discussion on fingerprinting techniques. They each provide a fingerprint for identification by another student. A...
Curated OER
Properties of Fresh and Sea Water
Students work with three stations to demonstrate the properties of water. They explore water's boiling point, freezing point, and its ability to store heat.
Curated OER
The Nature of Salt
Students record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights

Transformations of Energy
Seventh graders investigate the relationship between energy and matter, and measure the mass of various objects. They listen to a teacher-led lecture about potential energy, and in small groups measure the mass of various objects such...
Curated OER
Space and Time in Dance
Students move with control in general space. They move with three different spatial distances and tempi. Students demonstrate understanding of the distance and speed of particles in matter: solid-close and slow; liquid-medium distance...
