In this molecules worksheet, young scholars answer post lab questions about types of bonds, factors that determine polarity and molecular geometry. They calculate electronegativity differences in atoms and determine the types of bonds...

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

Explain the properties of water. Identify the properties of water that make it a polar molecule Describe hydrogen bonds and how they differ from covalent bonds Discuss the differences between hard water and soft water Compare the heat of...

Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that...

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second instructional activity of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils...

In this chemistry worksheet, students fill in the chart for question one. The chart is filled out examining the mass, protons, electrons, and neutrons for specific atoms.

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

High schoolers experiment with water as a component of suspensions, solutions, and heat conduction contributing to the use of food and the health and wellness of human beings.

For this intermolecular forces worksheet, young scholars read about the two types of forces: dispersion forces and dipole-dipole forces. Students then complete 2 problems based on what they read.

Students investigate the concept of molecular structure. They describe the behavior of simulated molecules and identify any dislocations in crystalline structures. They also define various related vocabulary words and use them in...

Students develop their own water molecule model to help them understand the idea that water has a slight positive charge at one end of the molecule and a slight negative charge at the other.
