Secret Formulas
Grades 1—3
Written by Rebecca Tilley and Carolyn
Willard
If you wanted to find a "secret formula" to produce a
guide that contained wildly popular, sweet, and tasty activities
solidly packed with math and science, you'd have it in Secret
Formulas! Students eagerly investigate the properties of
substances as they make their own personal brands of paste, toothpaste,
cola, and ice cream. The activities have been carefully designed
to convey key science/mathematics skills and concepts, provide highly
motivating real-life experiences with chemistry, and build student
understanding of cause and effect, central to later understanding
of controlled experimentation.
Secret Formulas speaks to the need expressed by many
primary school teachers for more hands-on physical science activities.
It makes an excellent connection to a number of other GEMS guides,
including Involving Dissolving
and Liquid Explorations. The extraordinary
level of student enthusiasm and involvement makes the educational
value of these inventive activities no secret at all!
Praise for Secret Formulas:
"Secret Formulas is another excellent publication from
the Lawrence Hall of Science (LHS)…Like scientists, students
must observe and describe the properties of substances, and they
are given repeated opportunities to understand and apply the concept
of cause and effect. …like all the LHS materials, Secret
Formulas features excellent teacher support. … Although
the unit requires a lot of time and preparation, I highly recommend
this wonderful and practical book for all teachers."
