In this electronegativity worksheet, students complete a chart given 10 molecules. They draw their Lewis structures, they draw the shape of the molecule, they determine the difference in electronegativity between the bonds, they...

After studying the different aspects of atoms and their reactivity, pupils will find this summary PowerPoint useful for review. Some of the slides are informative with labeled diagrams; others give important vocabulary. Teachers may want...

In this word search activity, students locate 12 words related to molecular bonding. Words include molecule, ions, forces, polarity, partial, and particles.

In this bonding worksheet, students read about the types of bonds that hold compounds together. They are given fifteen common materials and they identify the types of bonds that hold each together.

In this chemical bonding worksheet, high schoolers answer 10 questions about ionic bonding, covalent bonding, metallic bonding, Lewis structures, and intermolecular forces.

For this electronegativity worksheet, students use given electronegativity values for each element to determine the bond type in 9 molecules.

In this chemistry learning exercise, students explain the difference between a covalent bond and an ionic bond. Then they write the Lewis symbol for the atoms and ions presented, such as carbon and sulfur. Then they predict whether the...

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

In this creating bonds worksheet, students create 2-D and 3-D models of the molecular formula provided. Students complete a chart of information about the molecular formula given.

Even though the questions on this worksheet pertain to general chemistry, it was created for an AP biology course. It is crucial for biology learners to grasp these concepts as a foundation for biochemical processes that they will...

Although there are only six questions on this chemistry handout, it makes a thorough review of solutions. Novices explain why a compound is not an electrolyte, identify types of compounds, and calculate moles, grams, and molalilties in...

An educational presentation includes atoms, molecules, the four major elements, as well as neutrons and protons. Additionally, slides focus on atomic number, mass number, atomic weight, polar and nonpolar covalent bonding, ionic...

In this chemistry worksheet, high schoolers examine the concept of covalent bonds with the assessment. The answer key is included on page 3 and 4.

Does the mention of proteins and polypeptide relationships in your classroom result in mass confusion? Does the attempt to teach this important concept generate multiple questions and, at times, lead to a room filled with blank...

There is not much information in this presentation. It serves more as a guide to direct the flow of your introductory chemistry lecture. Each slide displays a large title and a smaller phrase meant to explain it. For example, one title...

A great review of the structure and function of carbon-based molecules important to life, especially with relevance to humans. The chemistry behind the combination of polymers and the breakdown of bonds is covered. Valuable content...

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...

For this water worksheet, students explore the reasons why water is considered a universal solvent. Students compare different ways to change the dissolving rate of a solute. This worksheet has 11 fill in the blank and 8 matching questions.

As long as you have some support information to answer questions that may come up from students, this is an excellent PowerPoint to cover almost all aspects of protein structure and ionization. The sequence of slides has great...

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...

For this AP Chemistry worksheet, learners apply concepts of electron configuration to accurately answer the questions provided. Students also draw Lewis structures of the given elements. Learners estimate the enthalpy of formation as...

In this solvent worksheet, students explore why water is considered a universal solvent. Students explore what can change dissolving rates. This worksheet has 8 matching, 3 short answer, 11 fill in the blank, and 4 problems to solve.

In this biologically important molecules worksheet, students fill in the blank with information about carbohydrates, lipids, and proteins. Students also make notes about nucleic acids.

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.
