In this activity, students will build a simple solar cooker, make observations and qualitatively describe the melting rate of a piece of chocolate in the cooker.
In this activity, students will examine the behavior of different types of solids when they are dissolved in water and explain those behaviors by examining the properties of the solids.
Students will examine two different techniques for mapping different aspects of the ocean, and will model those techniques on a small scale in the classroom.
In this activity, students will learn the different techniques used to map the ocean, and will practice using those techniques themselves in the classroom.
In this activity, students will gain an understanding of the value of using a scale model and the effect of water speed on erosion rate and stream formation.
In this activity, students will explore the relationship between angles of incident and reflected light and use this relationship to design and test their own periscopes in a classroom competition.
