Johnston Chemistry

Great activity for the beginning of a chemistry or other physical science class. Covers rounding, scientific notation, and basic algebra. This is great as a pre-assessment or an assessment after you have reviewed these concepts. *Find this activity and many more in my unit packet "Energy, Matter, and Mathematics of Science"*

This lab is great for Regents and non-Regents level high school chemistry in New York, any general chemistry or physical science courses at the middle or high school level, or forensic science. It does not require a lot of materials, so it can easily be used in a home-school environment also. Basic materials needed: pencils different brands of markers filter paper water acetone and/or alcohol beakers or other containers This lab contains Chemistry Regents Exam practice questions pertaining to

*Can be differentiated for different levels!* *Fully Editable!* Use this GoogleSlides activity to assign to your students as a guided Webquest research assignment where they can choose a career and research it. * Encourages student choice. * Each slide guides students to look up something specific about the organization. * Students are encouraged to synthesize information from text. * Reflection section allows students to discuss their findings. This activity may be done in a virtual setting

Claim, Evidence, Reasoning (CER) activity where students have to use the graph to decide the validity of the claim and prove their judgement using evidence from the table and reasoning to explain. *Find this activity and many more in my unit packet "Energy, Matter, and Mathematics of Science"*

This lab explores solution concentration, creation of supersaturated solutions, and recrystalization. Materials needed: large beakers water borax pipe cleaners string sticks/stir rods/micro spatulas hot cups (to grow crystals) Lab also includes assessment questions from the NYS Regents Examination.

Student practice doing calculations for heat of fusion and heat of vaporization. Includes prompts for students to write out the formula, show their work, and write their answer. Includes thought-provoking questions about using the formula for substances other than water. *Find this activity and many more in my unit packet "Energy, Matter, and Mathematics of Science"*

This web-based research assignment provides web resource and graphic organizer for students to investigate the historical development of the atom. It also allows students to organize this data in a timeline to get a better understanding of the time frame of the history.

This lab introduces students to the parts of the Bunsen burner and how they work. They will investigate how to use a striker to light the burner, how to prove the relative temperature of the different parts of the flame, and how to cut, fire polish, and bend glass using a wing-tip adapter. They will also practice using test tube tongs and heating substances in a Bunsen burner's flame. Materials needed: Bunsen burner with hose and gas hook-up goggles striker matches test tube tongs test tubes w

In this lab, students will practice many concentration calculations and do all the calculations needed to create 3 different molarities of Kool Aid. Students will then taste test the solutions to see which one is appropriate. Materials needed: Kool Aid Powder Filtered or bottled water plastic cups Plastic spoons digital balances Lab also includes assessment questions from the NYS Regents Examination.

This lab uses cut apart paint chips to simulate Mendeleev's organization of the first periodic table. Students are given a full set of paint chips (as many as you choose), with 5 missing. Students have to hypothesize the characteristics and locations of the missing elements. In general, my students' finished tables have 10 columns. The first 2 and last 4 have 4 rows, while the center have 3. Feel free to look through my Instagram @johnstonchemistry for examples. Lab also includes Regents ques

Interactive notes to understand and interpret a heating curve and form hypotheses about cooling curves and other substances. CER Activity where students will determine the validity of the claim using evidence and reasoning from the provided heating curve. *Find this activity and many more in my unit packet "Energy, Matter, and Mathematics of Science"*

A bundle of all of the labs in the course! HUGE SAVINGS!

This assignment includes a reading, reading comprehension prompt, writing activity, and a calculation related to the article context. Article discusses isotopes, atomic weaponry, and some of the historical significance of The Iran Deal.

This calorimetry lab can be done with either the use of a bunsen burner setup or a hot plate. It can be done as a demo with student assistance while the class collects the data and does the calculations together or as a traditional lab. In this version of the common high school staple, a lot of the extra background text has been removed, the data tables are easy to fill out, and the calculations are explained in a straightforward way. While this concept of conservation of energy is often chall

Student practice calculations for heat of fusion, heat of vaporization, and specific heat capacity. Students need to identify the correct formula, show their work, and report their answers. *Find this activity and many more in my unit packet "Energy, Matter, and Mathematics of Science"*

This activity introduces the Periodic Table with a short reading about Dimitri Mendeleev and his Periodic Table of the Elements. It allows students to think about the influential work of Mendeleev and the impact it had on past and future scientific discoveries.

This lab is extremely helpful in reinforcing the Bohr model of the atom. Students are asked to determine which element they are building based on the amount of protons, neutrons electrons. They must determine whether they have a neutral atom or an ion and the net charge. They will also determine the mass of the atom or ion. Lab also includes NYS Regents questions related to atomic structure. Materials needed: Bullseye images (printed or drawn on open file folders) Beakers (nucleus) Red, white,

This bundle includes all of the labs that I do during the Energy, Matter, and Mathematics of Science unit. (See corresponding unit packet.) Labs included: Safety Memes Rainbow Lab Heat of Fusion of Ice Density Separation of a Mixture: Experimental Design Separation of a Mixture: Paper Chromatography
