Never let your students confuse action-reaction and balanced forces again! This problem set will get the job done. Challenge your students to sketch and identify the action-reaction force pairs in each of the 24 scenarios included in this practice problem set. In includes an answer key with the table responses all filled out. This is the perfect problem set to use as homework or in-class practice, and it does an excellent job of presenting the students with lots of different situations to consider. Eventually, the students see the pattern in how the action and reaction force are related due to the repetitive nature of considering "What performs it?" and "On what is it performed?" for both forces.

Gravitational Potential Energy - Practice Problems - Great Worksheet w/ key! HS-PS3-2 2 examples and 19 original practice problems where students will solve the gravitational potential energy formula for GPE, mass, height, and gravity. This would make the perfect handout for teaching the skills or as a homework assignment! They key is elaborated, so it doesn’t just have the answers. It has all of the work shown. See it on TpT

Chemical Bonds Lab: Growing Ionic Crystals! Solutions, Solubility, Saturation This is a lab designed for 7-9th grades where students pick either halite, epsomite, or alum to grow crystals with. The student handout is comprehensive and thorough. Every year I do this lab the kids have a blast. It is designed for the teacher to do the heating for super saturation. I personally use a large griddle of my own to heat several beakers at a time. I recently acquired access to several hot plates and ran this lab by allowing students to do their own heating. It works either way! See it on TpT

This product was featured in TpT’s “10 FREE Downloads Newsletter” and has amassed over 1,600 downloads and nine 4-star reviews on TpT in merely a few months. See it on TpT Calculating weight and mass: 19 practice problems total. Alternate version included that has 3 example problems (one for each variable) and 16 practice problems. All original problems. Perfect homework, practice, or guided class activity for teaching these skills. This was a paid product until February 2018, but I decided to offer up a nicer freebie to help give buyers a better idea of what my best products are like. It has a $2 value, but if you will consider following me I’m glad to provide it to you for free. I hope you find it useful! Please review!!!

17 Ohm’s Law practice problems. Solving for voltage, current, and resistance. Challenge your students to master Ohm’s Law with this original problem set from Mr. Fry’s physical science.

Kinetic Energy - Practice Problems - Great Worksheet w/ key! HS-PS3-2 This is a great worksheet I made with 3 examples and 18 original practice problems where students will solve the kinetic energy formula for kinetic energy, mass, and velocity. This would make the perfect handout for teaching the skills or as a homework assignment! They key is elaborated, so it doesn’t just have the answers. It has all of the work shown. See it on TpT

This worksheet was designed to help my students get comfortable interpreting the numbers of valence electrons and energy levels for atoms using the group and period trends. It starts out with identifying numbers of energy levels and valence electrons, then requires students to rank elements using those numbers. Then it has students use the trends to identify both characteristics for the same elements. This is a quick activity to do together as a class or also works as a great homework assignment once the material is taught in class. See it on TpT
