Looking for a comprehensive plan for teaching acid-base chemistry? Science scholars discover acid-base interactions through a thoughtfully written unit. The resource is divided into paced activities and individual work designed to...

Why do the bases in DNA pair up the way they do? Unravel the mystery of the double helix in a virtual lab. Young scientists follow in the footsteps of Watson and Crick to determine the free energy associated with DNA base pair binding....

Is your acid-base chemistry lesson plan a little ho-hum? Spice things up with puzzles! Young chemists manipulate facts about acids and bases to solve a series of interactive puzzles. The activity combines content knowledge and...

How well do your young chemists know their acid-base reactions? Reinforce neutralization reaction and problem-solving skills with a challenging interactive. Learners examine the reactants, then predict the outcome in a series of...

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...

It's alive! Young mad scientists create monsters as they explore the probabilities of genetic traits during a well-structured inquiry lesson. Pairs travel from station to station, rolling the dice and adding traits to their creations as...

When the sun's rays can't reach the producers in a food web, where does all the energy come from? Extreme environments call for extreme food sources. Young scientists investigate creatures that appear to get their energy from methane...

How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...
