In a class discussion format, the teacher presents background information about basic human genetics. The number of chromosomes in both body cells and egg and sperm cells is covered, as well as the concept of dominant and recessive alleles. Students determine whether or not they possess the dominant allele for the tongue-rolling gene as an example.

How does our climate affect us? How do we decide what to wear each day? What factors determine if our clothing choices are comfortable? What is the source of our water? Students explore characteristics that define climatic regions. They learn how tropical, desert, coastal and alpine climates result in different lifestyle, clothing, water source and food options for the people who live there. They learn that a location's latitude, altitude, land features, weather conditions, and distance from large bodies of water, determines its climate. Students discuss how engineers help us adapt to all climates by designing clothing, shelters, weather technologies and clean water systems.

The teacher leads a discussion in which students identify the physical needs of animals, and then speculate on the needs of plants. With guidance from the teacher, the students then help design an experiment that can take place in the classroom to test whether or not plants need light and water in order to grow. Sunflower seeds are planted in plastic cups, and once germinated, are exposed to different conditions. In particular, within the classroom setting it is easy to test for the effects of light versus darkness, and watered versus non-watered conditions. During exposure of the plants to these different conditions, students measure growth of the seedlings every few days using non-standard measurement. After a few weeks, they compare the growth of plants exposed to the different conditions, and make pictorial bar graphs that demonstrate these comparisons.

Drinking water comes from many different sources, including surface water and groundwater. Environmental engineers analyze the physical properties of groundwater to predict how and where surface contaminants will travel. In this lesson, students will learn about several possible scenarios of contamination to drinking water. They will analyze the movement of example contaminants through groundwater such as environmental engineers must do (i.e., engineers identify and analyze existing contamination of water sources in order to produce high quality drinking water for consumers).

In this lesson, students will learn about kites and gliders and how these models can help in understanding the concept of flight. Students will design and build their own balsa wood models and experiment with different control surfaces. The goal of this lesson is for students to apply their existing knowledge about the four forces affecting flight and apply engineering design to develop a sound glider. They will also communicate the reasoning and results of any design modifications made.
