Challenge your students’ powers of deduction to determine which of four suspects committed several different burglaries. This module is low cost, easy to run, and versatile for a range of ages and durations.
In our post about molecular model kits for use with younger students, we’d mentioned seeing various “off-brand” versions of Molymod- and Minit-style model kits available for sale online. We’ve bought them to find out how they compare with “The Real Deal.” Are they mediocre quality knock-offs or a boon to small budgets?
3D graphics are great, but nothing provides the same experience as handling and manipulating a physical model. Children truly enjoy assembling these models, so it is worth the investment of time and money to purchase and/or borrow them. Here we introduce a range of different model types, along with their strengths and weaknesses for use with younger students.
Most children have heard about DNA, whether in terms of police detective work, discovering one’s ancestry, fighting cancer and other diseases, or most recently in the new highly effective mRNA vaccines. This module provides even young students the information to better understand what DNA is, and how it is essential to all life.
This module introduces students to proteins, crucial to all life and life processes, and the amino acids from which they are made.
This module introduces the concepts and techniques of titration. Children will employ this knowledge to determine the relative strengths of acidic and basic solutions by titration using very simple equipment and solve a variety of challenge scenarios.
Paper chromatography is a technique for separating out components in a mixture, such as for testing the purity of compounds. In this module, Kidizen scientists will study the composition and separation behaviors of a variety marker types and colors. They will then employ this knowledge and their chromatography skills to identify the various mystery markers from their inks alone!
How can you tell how acidic or basic something is? Touching or tasting it could be dangerous or unpleasant. In this activity, students use indicator papers made from familiar fruits & vegetables to see which are the best at measuring pH.
A mysterious white powder! What could it be? Our young investigators will sleuth out the identities of the mystery mixtures by first building an “answer key” for how the individual “known” powders react to a variety of tests. Then they’ll use this key to figure out what pair of powders are in each unknown mixture by subjecting them to these same tests.
