Chemistry

Students learn the relationship between pressure and air volume and how air volume acts to regulate buoyancy by constructing cartesian divers made of simple equipment and materials. Procedures for constructing 11 different types of cartesian divers a...

In a chemical reaction, matter is neither created nor destroyed, except in this apparent contradictory experiment! Students will understand what is really measured when we “weigh” something on a balance. Students first conduct an experiment to note t...

Don't just give your students the definition and equation for density-let them discover the concept for themselves! Using either “gold” or “silver” metal shot, students collect mass and volume data, plot the data on a graph to...

Density-it's one of the first topics taught in every science class! Why spend time scrounging up density materials for a hands-on lab when you can have them ready to go in a moment's notice? This economical lab kit provides a complete introduction to...

Before da Vinci could write his “code,” he needed ink. Where did he get the ink? He made it! Students will go back in time to the Middle Ages to discover the chemistry behind the ancient process of making ink. After investigating the chemical reactio...

Let the creativity flow as students create their own personalized “designer” goggles! With this colorful goggle-dyeing kit, students can choose their favorite colors, school colors, or multi-colors and turn a standard pair of chemical-splash goggles ...

Give your students a challenge-the measurement challenge! With this innovative teacher-designed kit, students learn to make accurate measurements, estimate to the proper level of certainty, and apply rules for significant figures in calculations. Han...

Use this series of hands-on activity kits to teach students the principles and fundamentals of laboratory measurement. Students learn important measurement concepts relating to the metric system, accuracy and precision, and how to convert units of me...

Help your students develop key measurement skills with this comprehensive lab activity. Students learn to use good laboratory techniques as they conduct six separate lab activities in which length, mass, temperature, and concentration are measured an...

Students will have no fear as they enter the wildlife “unit-factoring” refuge! Students often forget to include units when solving problems or recording measurements, yet numbers without units are often meaningless. Take the confusion out of dimensio...
