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!!!

Periodic Table - Groups vs. Periods Practice / Review Sheet - Using the Trends HS-PS1-1 Here is an excellent resource I made for practicing or reviewing the group vs. period trends, including numbers of valence electrons and numbers of energy levels. It is a two page student handout (1 pg. front and back) and a complete teacher’s key. See it on TpT

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.

Conservación de la Energía Mecánica ELL Support for Conservation of Mechanical Energy Practice Problems Available in English here This practice problem set is designed to provide practice for students using their knowledge of the conservation of energy to substitute values between the formulas for kinetic and gravitational potential energy to solve problems. It includes 8 original problems and one example plus 2 multi-step pendulum problems. Complete with elaborated answer key! NGSS Correlation: HS-PS3-2

A nice worksheet for homework or simply class practice that covers classification of matter and conservation of mass. It includes matching as well as engaging classification questions that require higher order thinking skills. See it on TpT

Spanish ELL Support for Density Practice Problems. I speak fluent Spanish, so this was translated for real, NOT using Google translate. 14 problemas de practica usando la formula para densidad para todos los variables. Disponible en ingles/Available in English

Challenge your students with these 24 practice problems for mass to moles and moles to mass conversions for elements (front) and compounds (back). This is perfect for teaching these skills, as extra practice for in class or for homework, or even as a quiz. Answer key included!

Have your students hypothesis-build and test on the question of how achromatic color affects electromagnetic energy absorption using this powerful and beautifully simplistic lab design. Included is the student handout to be used to create a lab report, an area to graph the data, as well as photos for the teacher to help see how I run the lab. You can modify the design and still have a great time with your kids! The main objectives of the lab are to determine if and how achromatic color affects the absoption of energy as well as using the specific heat formula to solve for how much energy was absorbed by the water. This lab can be adapted for lower grades by not utilizing the specific heat formula objective. Supplies Needed: (1 per group) Lamp with infrared bulb (see preview for photos) Temperature probe or thermometer Ring stand with 1 small and 1 large iron ring Clamp to secure temp probe or thermometer 100 ml distilled water 3 soda cans wrapped in construction paper with the tops left open (1 white, 1 gray, and 1 black) That’s it! Please review! The kids will love it!

Challenge your students with these 14 original density problems where they solve for all variables in the density formula and more!

24 practice problems in counting atoms in compounds. First page focuses on compounds with formulas that do not have parenthesis or coefficients. The second sheet/back has 12 problems with parentheses and coefficients (both stoichiometric and in hydrates). Great homework or for teaching these skills. Designed as drill practice to reinforce instruction. Scaffolded for advanced students by requiring them to list compounds’ constituant atoms before counting as well as requiring them to look up compound names. You can modify this part of the assignment as you wish. Enjoy! Please review and follow!

7 original specific heat problems where students are tasked with solving for all variables in Q = mc∆T. See it on TpT

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.

Challenge your students with these 18 practice problems with the wave speed formula! This is the perfect homework assignment, extra practice problems, or could be used as a teacher-led activity for when teaching these skills. The questions have students solve for all 3 variables in the wave speed equation. HS-PS4-1 I have included an alternate version that has the first 3 problems solved as examples. This alternate version is NOT included in the page count on this listing. These are high-impact practice exercises! Please review and follow my store!

15 question worksheet with detailed instructions in which the student has to either write the formula or correctly name different covalent compounds. Excellent to teach the skill or as extra practice or homework. See it on TpT
