What does it mean to help students develop a small particle model of matter? The Mystery Bubble task is intended to elicit preservice teachers’ CKT related to students’ ideas about the small particle model (SPM) for matter, particularly the idea of empty space between the particles. The task presents a phenomenon in which combining ethanol and water results in a mixture that occupies less space than the combined volume of each.

What is a scientific explanation and how can we support students in explaining changes in matter? The Fizzy Antacid task is intended to elicit and develop preservice teachers’ CKT related to students’ scientific explanations of changes in matter. The first part of the task asks preservice teachers to develop their own explanations and engage in scientific argumentation, while considering how elementary students might explain the Fizzy Antacid phenomenon.

What investigations can help students best understand conservation of matter? The Investigating Matter tasks are intended to elicit preservice teachers’ CKT related to the conservation of matter. The open-ended task asks preservice teachers to identify an investigation that would provide students with evidence to support this idea, while the multiple-choice version, Selecting Investigation of Matter, provides them several alternatives to consider.

What kinds of questions should guide investigations of matter? The Questions to Investigate task is intended to elicit preservice teachers’ CKT related to asking questions to frame investigations of changes in matter. The task presents a variety of student-posed questions for preservice teachers to evaluate in terms of their quality and appropriateness. The CKT tasks are intended as a complement to your existing instructional activities in order to elicit and probe preservice teachers’ CKT.

"Evolution: DNA and the Unity of Life" is an eight-week, comprehensive curriculum unit that sharply illuminates the underlying role of genetics in evolution by maintaining a conceptual connection to DNA and heredity throughout. Through paper-based and interactive multimedia lessons, the unit aligns with the Next Generation Science Standards (NGSS) by engaging students in questioning, using models, identifying patterns, analyzing skill-level appropriate data from published scientific studies, and constructing evidence-based arguments. The unit’s lessons are organized into five modules.
