In this activity, learners start their own field journal to better understand the wildlife in their area.

This activity is about collecting and analyzing DNA as part of a criminal investigation.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this genetics activity, learners discover how to extract DNA from green split peas.

In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

Whether it's the genetic code, an ancient language, or patterns of light in a distant galaxy, scientists often have to play the role of decoder.
