This is hands down the ultimate worksheet for writing and naming ionic and covalent formulas. I get great results with it each year, and it is very versatile. This could be used as a class activity when teaching these skills, extra practice or homework, or even a quiz for advanced classes. See file preview for a sample with answers. 24 questions total that challenge students to classify the compound as ionic or covalent first, then they either write out the compound name or its chemical formula.

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!

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

“The Coldest Drink”- Inquiry-Based Lab & Design Challenge (Thermal energy) This is a really fun inquiry-based lab/design challenge lab that asks students to develop their own procedure for creating the “Coldest Drink.” This lab aligns with the NGSS. This is the elaborated 5-page student handout that steps students through designing a lab of their own, including a creation of a procedure, sketching of particle motion, data collection, and graphing data. Feel free to look through the preview! Enjoy! See it on TpT

Propiedades y Cambios Físicos y Químicos ELL Support for Spanish (Physical & Chemical Properties & Change) I speak fluent Spanish, so this was translated for real and NOT by Google translate. Available in English here

Energía Cinética ELL Support for Kinetic Energy Practice Problems NGSS Correlation: HS-PS3-2 This was translated for real, NOT using Google translate. Available in English here 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. I have also included an alternate version that repusposes the examples as additional problems. 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.

3 examples and 15 practice problems using the power equation to solve for power, work/energy, and time. Alternate version of the file is included that does not utilize the examples and is simply 18 practice problems. Both versions included. See it on TpT

Invisi-Tables! Indirect Evidence Analog for Gold Foil Experiment (Nucleus) Fun! See it on TpT This is a really fun lab I made for my 9th grade Physical Science classes, but it can easily be adapted for pretty much any age level where the teacher wants to introduce indirect evidence. The students are tasked with using nothing but the rolls of a marble to discover what is hidden under the Invisi-Table. Where are the objects? How many are there? They actually sketch a picture of what is under it without having to look! It is a perfect low budget way of simulating Rutherford’s gold foil experiment, where here the marble represents the alpha particles that were shot at the gold atoms and the objects under the table represent an unknown structure like the nucleus was to Rutherford during his research. I’ve used it 3 years in a row with great success each time. It is very simple yet engaging and will keep the kids thinking. It is also re-usable every year. The tables themselves don’t take up much room. Includes comprehensive student lab handout and a brief section for the teacher on how to build Invisi-Tables, which includes pictures of all 6 of the ones I have used for 3 years in a row! Materials for each student/group: a standard glass marble, ruler, and lab notebooks or paper. Materials for making Invisi-Tables: Glue gun, approximately 12" x 24" thin boards, 4 rubber stoppers per table for the legs, and some small random objects to glue under the tables themselves. This is definitely worth doing. Please share you experiences with it in the reviews or comments. This file will likely be updated for free in the future. Any updates will be documented here. Thanks very much for your business.

Lab Activity: Ziplock Pressure Chamber & Pouring CO2 Gas to Extinguish Candle! See it on TpT This is a really fun lab activity I designed for my 9th grade physical science class, but it can be easily adapted for other grade levels. There is an open flame in the form of one or more candles depending on how you run the room. In the first activity, the students follow procedure and measure baking soda and vinegar, then strategically mix them in a baggie without allowing them to mix until all air is removed and the baggie is sealed. Sit back and watch their eyes when they allow them to mix and they learn what pressure is hands on! In the second activity, they practice measuring the same substances, but this time they create the CO2 gas in a beaker, then pour it down a paper trough to extinguish a candle! It’s a fun challenge, but they absolutely lose their minds when they succeed! The lab includes thought provoking questions about pressure and the density of CO2.
