Affinity Teacher Resources

Learners use the on-line affine recurrence plotter to graph equations. They work on-line to create graphs of trout in a trout pond and savings account balances when interest is compounded over time. Links to the four one-day lessons are...

Chemists compare the electronegativity, ionization energy, electron affinity, and ionic radius of different elements. This learning exercise is composed of 11 multiple choice questions, and 8 written explanations. Critical thinking...

Thorough explanations of the trends in the periodic table of elements make up the majority of this handout. Atomic and ionic size, ionization energy, electron affinity, and electronegativity are presented before giving chemistry...

What do dipoles say in passing? Have you got a moment? Videos begin with ionization energy, then move on to covalent bonds, polar-covalent bonds, and ionic bonds. After a discussion of dipole moments, a video quiz reviews the material....

An atom's ability to lose an electron or attract an electron is not created equal! A thorough video lesson explains the concept of shielding and electron affinity. Learners understand the farther an electron is from the nucleus, the...

A huge collection of slides introduces chemistry learners to the periodic table of elements, electron configuration, and electronegativity. It opens with the history of today's periodic table, and then details the arrangement. After...

In this periodic trends activity, students solve ten problems related to elements in the periodic table. Students write electron configurations for atoms and they compare elements and their periodic trends.

Second graders identify the three phases of matter and demonstrate how a property can change states of matter. In this states of matter activity, 2nd graders make an Ooze to discover how a solid changes into a liquid. Students...

In this electron configuration and periodicity instructional activity, students answer fifteen questions about periodic trends and they analyze orbital diagrams indicating location of electrons.

America has a long history of presidents with an affinity for the truth, from Honest Abe to George Washington and his cherry tree. A short passage features Washington's infamous hatchet and confession, and includes four comprehension...

Geckos are reptilian superheroes, defying gravity to climb walls and hang from ceilings, but where did they get these amazing superpowers? Watch this fun video as it examines the amazingly designed feet of these unique animals and...

It'll be difficult to stay positive through this lesson! Discuss electronegativity with your classes with a video introduction. The lesson defines electronegativity and then references the periodic table while highlighting different...

High schoolers investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.

Learners perform basic operations in modular (clock) arithmetic. Students encode and decode messages using shift and affine ciphers. Learners apply their multiplication, division, addition, and subtraction skills.

In this elements worksheet, students write the electron configurations for given elements. Students describe ionization energy and electron affinity and the periodic trends for both. This worksheet has 20 short answer questions.

Students articulate their understanding of the framers' intentions with respect to the separation of church and state, explore the issue of church/state separation and how it is currently manifesting itself in Ohio by reading and...

Students examine various careers and character traits. They create an Affinity Chart using career survey results, compare/contrast personality traits and character traits, and discuss why character traits are important for jobs.

If Hemoglobin and Red Blood Cells play an important role in your curriculum or have piqued your students' interest, then this video would be an asset for understanding that higher acidity and Carbon Dioxide play an allosteric inhibition...

Sal discusses what happens to elements when they become ionized. He demonstrates that when neutral atoms become ionized, it can significantly change their relative atomic sizes. He uses the Periodic Table of the Elements to illustrate...

This concise collection of images speaks volumes about the trends in the periodic table of elements. Different versions of the periodic table are displayed demonstrating different trends. Teachers' notes are included to assist your...

Perfect for native or non-native English speakers, this antonym worksheet has learners look at 10 words and choose their antonym out of five listed choices. Example words include fervor, static, merciful, and vivacious. 

Caesar ciphers hide secret missives. A simple interactive lets users encode and decode hidden messages. The cipher method here is the Caesar shift.

Blend chemistry with cooking in this exploration of polymers, carbohydrates, and food science. Experimenting with gelatin produces concrete examples of the bonding and ploymerization discussed in the lesson. Copious, comprehensive...

While this resource does not provide problems for chemistry learners to solve, it outlines skills that they should have and concepts that they should grasp. Topics include thermodynamics, periodicity, redox equilibria, transition metals,...
