Inquiry: Drawing Conclusions Based on Evidence

Students first will explore the steps of scientific investigation as they observe, record and predict what the 6th side of a cube looks like based on observations of the 5 visible sides. The second step involves a second, more complex cube, but allows students to “peek” at one corner of the face-down side to conclude their observations. A final exercise involves the participants creating their own cube that follows patterns for others to observe.

Mystery Boxes

Using shoe boxes wrapped with rubber bands and filled with every day items (peanut, pine cone, tennis ball, etc), children can manipulate the box to collect observations and make an inference as to the item's identity, following the scientific process.

The Formulation of Explanations: Natural Selection

Participants will analyze a story problem about pest control and learn about forming hypotheses based on evidence. The story will lead to a discussion of evolution and natural selection, the most logical hypothesis based on the evidence presented in the story.

What Material Makes Good Swimsuits?

After brainstorming the important qualities of swimsuit fabric, kids can use a variety of fabric samples, water, a ruler and a scale to determine which fabrics will make the best swimsuits. A discussion of the scientific method can be incorporated into the process.
