The purpose of this lab activity is to demonstrate (through simulation) how DNA fingerprinting (or DNA profiling) might be used to solve a crime.

In this chemistry demonstration, acid rain is simulated in a petri dish.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

This activity was designed for blind learners, but all types of learners can model how vibrating particles, such as in a sound wave, bump into other particles causing them to vibrate, and that the vib

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

In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.
