In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.

In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.

In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).
