When life hands you lemons ... experiment on them! Green chemistry gurus compare extraction methods for essential oils through a lab activity. Lab groups use traditional distillation and liquid carbon dioxide extraction...

Five fabulous procedures introduce physics or chemistry classes to special properties of matter. They discover adhesion and cohesion, solubility, melting and boiling points, and viscosity through hands-on experiences. Tests are...

Is DNA still present after picking fruit or cooking vegetables? Biology scholars extract and collect DNA strands in an impactful lab. Working groups prepare their samples and compare their results to negative and positive standard...

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

Extracting oil is more difficult than many think! Learners work together and get hands-on as they represent oil companies drilling for oil by simulating oil extraction using beans. They identify the challenges faced in using...

Enzymes proofread DNA, reducing the error rate to one in one billion base pairs. Learn about the important process and so much more with the help of a presentation. It opens with the history of DNA and the major scientific contributions...

The final video in a series on Special Relativity offers a new hands-on approach to solving the twins paradox developed by Paul Langevin over 100 years ago.

Scholars become detectives and use science to solve a crime! A complete unit introduces DNA and includes hands-on activities that have learners model DNA and extract it from different food types. A culminating activity challenges...

Is copper found as a raw material? Science sleuths manipulate the reactants and products found in the copper extraction process in a series of fun puzzles. The interactive engages learners in pairing formulas with their names while using...

After viewing this presentation, students create a complete set of notes to support their learning of DNA replication. Each slide has information on a step in DNA synthesis process. The slides focus primarily on the processes rather than...
