Separation of Mixtures Lab & Rubric

Created by

In this lab students devise their own unique strategies to separate a mixture of water, methanol, sand, salt, iron and copper. Each component of the mixture should be analyzed quantitatively for its mass, percent composition as well as percent error as compared to the actual value. (note: the teacher or instructor needs to create the stock samples and must know the actual value of each component in the mixture). I would recommend using between 40 - 130 grams of water, 3 - 8 grams methanol, 2

Cellular Respiration Equation Assessment

Created by

Science Sensation

This formative assessment ensures students are working towards NGSS HSLS1-7 by memorizing the equation for cellular respiration. Students must write the equation as described in words and the chemical formulas. In addition to learning the reactants and products for cellular respiration students must also use symbols correctly and balance the equation. This rubric also helps teachers differentiate future instruction for those students ready to move ahead from those that need more practice.

Cell Organelle Mutation Project | Hero or Hazard Biology Activity

Created by

JJZ Biology

This takes a fun cell organelle project idea and turns it into a complete, PRINT-AND-GO biology activity.In this cell organelle mutation activity, students design a biologically plausible mutation to one organelle, predict how that mutation affects the cell and the whole organism, and decide whether the result becomes a superpower, a hazard, or both.Instead of simply matching organelles to functions or labeling another cell diagram, students use what they know about cell organelle structure and
