In this worksheet, students are asked to identify the bonding charge of two reactants (single atoms, no polyatomic), then determine the resulting chemical formula. The reactions used are simple ionic bonding, to introduce the students to this basic chemistry concept. The worksheet includes 14 practice problems, as well as an answer key.
In this worksheet, students practice some basic skills surrounding atoms. How many protons, neutrons, or electrons do they have? What are their atomic masses and atomic numbers? They practice these skills by filling information into a table. I have provided some of the information, and they need to use it to fill in the blanks. For instance, if I state that an element has 20 protons, its atomic number must be 20. Students are then asked to use their periodic tables to collect the same information for several other elements (ones that aren’t included in the first part of the worksheet). In this way, students learn to use the periodic table to collect this information, as well as how to use information they know about an element to figure out the missing parts. On the back of the worksheet, they’re tasked with drawing Bohr models of a few atoms (only the first two electron levels), then identify how many valence electrons the element has. This is a great worksheet for basic chemistry skills, either in middle school, or 9th grade physical science, or perhaps even chemistry, as a refresher/check.
In this worksheet, students are asked to demonstrate knowledge of a variety of forces and motion topics, including: -Speed -Combined forces (in one dimension) -Newton’s Laws -Friction The focus of the worksheet is the forces portion (Newton’s Laws, friction, combined forces), with only a few problems being over motion (speed). I have a separate worksheet that focuses on speed (and acceleration). The worksheet includes an answer key, and is 19 questions long. There are no multiple choice questions, and all questions require at least a basic application of knowledge. I use this for my 7th grade classroom, but it would fit equally well in a freshman science class, or with small tweaks, a high school physics class.
In this worksheet, students are given a data table containing two “like” sets of data (height of boys and girls, vs age). Students are asked to graph this data on a single line graph, then interpret the data, to answer a few simple questions. There is also an answer key included.
Simple homework/class activity, where students pick an object, and write down five good observations about it. They then use these observations to come up with one inference about the object. The purpose of the activity is to practice creating GOOD observations. Could easily be done in a 5-10 minute classroom activity/discussion, or done as homework, then discussed the following day.
This worksheet provides 40 practice problems over balancing equations. They range in difficulty from simple (already balanced) to very challenging. I have the worksheet set up so MOST of the challenging ones are on the second page. I have my students work on the first page with a partner in class, then finish for homework, and leave the second page as extra credit, for those who are grasping the concept, and want to challenge themselves. To save space, I have students do their scratch work on notebook paper, and staple it to their worksheet (which shows the problems, and students answers only) The worksheet includes an answer key. I have also included a 9-question quiz, with space for scratch work. The quiz is over some of the easier problems, as the goal (in my mind) is to see if they understand the process, not how to reason through the math involved in some of the tougher problems. Number 9 is a tougher problem, as it contains multiple instances of Hydrogen on the reactant side, as well as a polyatomic ion that shows up on both sides. The document is in Word format, so teachers can adjust the quiz for the level of their students. The quiz also includes an answer key.
In this worksheet, students will be asked to: -Identify whether an example is a chemical change, or a physical change, then defend their answer (signs of a reaction, or explanation of why it’s not) (9 questions) -Fill in some missing words in statements that demonstrate an understanding chemical and physical change (5 questions) -Identify the reactant(s), reaction, and product(s) in a written reaction (2 questions) An answer key is also included
In this straightforward worksheet, students are given a written chemical reaction, and asked to identify whether it’s an example of synthesis, decomposition, single displacement, or double displacement. This worksheet would work well with a chemistry class, or 9th grade physical science class, but I’ve also used it for my advanced 7th grade physical science class before, with good success. There are 24 questions, and an answer key is included.
I had the hardest time finding a good, simple, easy to read periodic table for my students to use in physical science/chemistry. I wanted it to be easy to read, contain rounded mass numbers, and be nice and clean, so my students could label it, and color it, as we learned about the various aspects of chemistry. I sat down, and in Word, created a box for each element, filled them in, then arranged them into the table, and presto (it took FOREVER), I had exactly what I wanted. Now YOU don’t have to! EVERY aspect of the table is editable, so you can tweak things, if you’d like, without having to create it from scratch! I print these on white cardstock, have them 3-hole punched, and have a student aide put hole protectors on two of the holes. Even my middle school students manage to make them survive the whole year like this! This includes atomic number 1-103, with the lanthanide/actinide series pulled out at the bottom I’ve included a BLANK periodic table: -Symbols -Names -Atomic Number -Rounded mass number -KEY on hyrdrogen -General labels for location of metals, nonmetals, noble gasses, transition elements, lanthanide, actinide …and a FILLED periodic table -Color coded (with key) for metals, nonmetals, metalloids, liquids, gasses. -Group and period numbers -Bonding charges (Group 1/2, 15-18) -Valence electrons (Group 1/2, 13-18) -Special note on helium for valence, since it doesn’t follow the pattern.
This worksheet (with an optional companion video!) has students practice the skill of taking a chemical formula, and determining the elements int he formula, as well as the number of atoms of each. This skill is critical to any higher level chemistry class. Stoichiometry, balancing equations, proportions, molar ratios, etc… Whatever you want to call it. The worksheet focuses mostly on subscript (or lack thereof), parentheses (single), and elements that show up more than one in a formula. I do not cover coefficients (though, these are covered in the video), or double parentheses. An answer key is included! As with all of my worksheets, I provide them in Word format, and encourage you to tweak them, and make them work for your situation.
In this worksheet, covering the topics of speed and acceleration, students are asked to complete 23 questions, ranging from direct calculations (here’s your distance, here’s your time) to simple story problems. In addition, two bonus questions are included at the end of the worksheet for students who need a challenge. Of them requires students to convert between time units in their speed calculation, while the other requires them to determine the rate of acceleration in a situation, rather than the resulting speed. An answer key is included. I use this in my 7th grade classroom, but it could easily be used in a freshman science class, or high school physics, perhaps with some adjustment to difficulty.
A RAFT is a short writing assignment where students take on a ROLE, address a certain AUDIENCE, in a particular FORMAT, about a given TOPIC. For my science class, since my focus is on the SCIENCE, rather than the writing, I keep the format simple…a letter. In this RAFT, students play the role of an everyday object, and explain how static charges affect their interaction with objects around them. Students will have two RAFTs to choose from. Included is an example of a class brainstorming session that should give you an idea of what that might look like, as well as an example RAFT, about a different science topic, so you can see how a RAFT comes together. I typically score mine in this fashion: Accurate and complete science content = 75% Correct grammar/spelling = 20% Proper format = 5%
This is a simple flowchart I put together for a student that needed a visual during our energy unit. The flowchart focuses on the CEMENTS (chemical, electromagnetic, mechanical, electrical, nuclear, thermal, sound) naming for the types of energy, and shows how mechanical energy can be further broken down into kinetic/potential, and potential, into gravitational and elastic.
This basic lab report can be used generically with many labs. Students are given a problem to solve, or question to answer. They make a prediction, backing it up with observations, then complete the lab, collecting data and observations as they go. They then try to explain the science behind their observations using information from their notes, or prior experiences. Finally, they’re asked to explain what the investigation proves, again, backing it up with observations from the lab.
A RAFT is a short writing assignment where students take on a ROLE, address a certain AUDIENCE, in a particular FORMAT, about a given TOPIC. For my science class, since my focus is on the SCIENCE, rather than the writing, I keep the format simple…a letter. In this RAFT, students play the role of a proton, and choose to either write a love letter to an electron, or a letter to another proton, explaining why they can’t be friends. Included is an example of a class brainstorming session that should give you an idea of what that might look like, as well as an example RAFT, about a different science topic, so you can see how a RAFT comes together. I typically score mine in this fashion: Accurate and complete science content = 75% Correct grammar/spelling = 20% Proper format = 5%
In this 9-day-long project, students work as a team to construct a large roller coaster out of foam pipe insulation The project progresses through multiple stages: -Small-scale testing -Designing the full scale coaster (on paper), based on the testing -Creating a prototype full-scale coaster based on their design -Tweaking the design to overcome flaws and challenges -Creating an “advertisement” type poster for their coaster -Creating a written set of ‘reflection’ questions about the process -Building and showing off their final roller coaster design This whole process takes 9 class periods (50min classes), but this can easily be tweaked to fit your schedule. I’ve created a packet that groups will have access to during each class period, outlining the expectations for each stage. The document also includes a score sheet, where students can see where the points are in each stage, and it also creates a simple way for the teacher to document group scores as the project progresses. All of the materials are in WORD format, and I encourage you to tweak, adjust, adapt the project to fit your needs. It could easily be adjusted to focus on energy conversions/conservation, engineering/design, or force (gravitational force, Newton’s Laws, etc). I use this activity as my final project, at the end of our energy unit, prior to diving into some review and prep for my year-end final exam. As is, it’s light on the academics, focusing more on teamwork, design challenges, and the ability to reflect on the creative process. My students love this project! Every year, I have new students whose older siblings have told them about the project, and how much fun it was!
This is a comprehensive foldable that includes the following information: -Definition of energy -Specifics of KE, PE -PE is then broken into PEgrav and PEelastic -7 Types of energy -Energy Conservation -Energy Conversions The foldable is broken into four flaps, with the front/back of each flap being used. The thumbnail gives you an idea of how each main tab is further cut/broken up. Materials: Two different colors of construction paper, scissors, rulers, staplers Foldables are a great way to give students a compact, visual study guide. The download includes the unit notes (Word format), Smartboard (Notebook) step-by-step directions for creating the foldable, as well as a PDF of the step-by-step directions. My students love making these (they call it “arts and crafts time”), and they make studying/review more fun for them.
In this activity, which my kids LOVE, students must quickly scramble to think of concepts/ideas/topics that they’ve learned about over the course of the year, and list them, within a time limit. The game can be played in any subject, and should be easy to understand for ages 10+. The game will take approximately one 45 minute class, depending on how quickly you move the students along, versus allowing them to “express themselves” during the scoring section of the game! Following this portion of the activity, the class moves through the scoring round, where topics are shared with the whole class. It’s a fast paced game that my students found exciting, and fun. I used it as a kickstarter for our end-of-year final test preparation/review. It’s a great way to get them thinking about all of the material that’s been covered during the year! The only materials you need are some construction paper (or index cards), and some way to project a timer for the class to see.
In this activity, students explore how gravity and friction (air resistance) affect the speed of a following object. Students will work in groups of 2-3. The activity takes one class period (~45 minutes), including intro, lab, post-discussion. The materials needed are: one sheet of paper per group (cut into two halves), a heavy book that’s larger than the 1/2 sheet of paper, and a chair to stand on. My students enjoy this activity, as it’s a bit counter-intuitive. The lab is in Word format, so feel free to adjust/adapt it to fit your needs, and the needs of your students. There is also a companion video for the lab available, should you want to see how it’s done, or provide it as a way for students to make up a missed lab.
My students love foldable notes. The combination of being manipulative, something they created…and honestly, NOT a bunch of typical comp book notes, makes them more interested in revisiting the notes outside of class. Foldable Requires: -2 sheets of construction paper (different colors) -Tape/stapler -Scissors -Ruler/straightedge When finished, the foldable will show the 3 rock types on the outside, as well as “The Rock Cycle”. On the inside, students will find definitions of each (provided by you)
