Help students learn the process of DNA Replication with these paper models. Available to print in both B & W and color options, you can choose the best size for your models. This year I printed models on large 11x17 paper and made a big model I used on the tabletops and later taped it on the wall to be a visual study area. Then I had students use smaller models later to practice explaining the process with a partner. At quiz time I covered the wall with a piece of butcher paper. You might a

A timely review of macromolecules well-suited for Thanksgiving or Halloween time! An information sheet connects pumpkin seeds to the four major groups of macromolecules - proteins, carbohydrates, lipids, and nucleic acids. An accompanying student worksheet asks questions that review macromolecule basics and draws out connections to pumpkin seeds. Answer key included. Provide students a pumpkin seed to sample while they work. Perhaps they've never tried them! OR If you're digging the pumpki

In this activity, students use short authentic science articles to practice identifying key elements of experimental design, including the research question, independent variable, dependent variable, constants, control set-up, and experimental set-up. The articles can be printed for students or accessed electronically through links to the sites. This activity introduces NGSS Science and Engineering Practices including Asking Questions and Defining Problems, Planning and Carrying Out Investig

Give students an opportunity for some hands-on fun! Examine concepts related to cellular respiration, including aerobic and anaerobic respiration, and especially starring the process of alcoholic fermentation by yeast! Most of my students had never made bread before, so this was an adventure for us, and they practiced something they may be able to use at home. This resources includes a teacher's guide with instructions for how to set up this lab across days and student handout with the recip

The cell is a staple of any life science or biology course. Looking for a simple way to get students understanding limitations on cell size? Marshmallows to the rescue! Students use marshmallows (mini, regular, and jumbo sizes) as model cells and follow the lab instructions to calculate their surface areas and volumes. Follow-up questions will help you assess students' understanding. Feedback for freebies is appreciated! Thanks! Happy teaching!! ~ . ~ . ~ . ~ . ~ . ~ . ~ . ~ . ~ . ~ .

Review DNA vocabulary using a Bingo game! Includes printable materials and teaching instructions. Vocabulary terms are related to basic DNA structure, DNA replication, and protein synthesis: adenine, amino acids, anticodon, backbone, codon, cytosine, deoxyribose, DNA polymerase, DNA replication, double helix, exon, frameshift mutation, genome, guanine, helicase, human genome project, intron, mRNA, nitrogenous bases, nucleotide, point mutation, protein synthesis, purines, pyrimidines, ribose, RN

Animal Behavior - Crash Course Biology #25 This resource includes a student worksheet to use while watching this CrashCourse episode. CrashCourse videos are excellent resources by Hank Green. They are entertaining and engaging for the high school classroom. They are packed full of information, but they move fast! Students need a tool to identify main ideas and keep focused. That's where these guides fit in! An answer key is included, as well as a copy transcript of the program for easy refer

Two fun lab activities that use simple materials to boost student learning about properties of water (hydrogen bonding, polar covalent bonds, cohesion, adhesion, surface tension). Teacher instructions clearly explain the materials and procedures for each activity, as well as options for collecting student data. Enjoy! *Follow the Science Classy Store!

These are two resources to help in teaching blood type genetics. 1) For students completing a real or simulated blood-typing lab, there is a pre-lab table. This helps students organize their knowledge of the different antigens on red blood cells and antibodies in blood serum, and predict what they will see in the lab as results for each blood type. 2) For students studying blood transfusions, there is a table for identifying which blood types are compatible. This requires that students alr

Micropipet Technique Activity: Color Wheel!Students practice correctly using a micropipet/micropipette in a fun, colorful activity using food coloring and circular filter paper! Variations of this lab abound. I've modified this classic activity into a concise, student-friendly format, and made a short PowerPoint that can be displayed as you teach students the basic parts and functioning of a micropipet. ENJOY this FREEBIE! Feedback is appreciated. Thank you! :) ~ . ~ . ~ . ~ . ~ . ~ . ~ .

Biology is the study of life. Often the first notes taken in a biology class are - what makes something alive?? Let your first notes be unique and active for the students, plus low prep for you!! Students can use their textbook or other source to get a basic understanding of the features that are generally considered to be common to all living things. Then their notes can be folded into the childhood classic form of a cootie catcher!

This is a version of a popular simulated enzyme lab. In this lab, students simulate a chemical reaction that is catalyzed by an enzyme. Then they change variables to learn how reaction rate is affected. The reaction is a hydrolysis reaction that splits a disaccharide, called paperose, into monosaccharides A and B.

HHMI Biointeractive has lots of awesome resources for teaching Biology. For teaching genetics and evolution, they have multiple resources to accompany their video Making of the Fittest: Natural Selection in Humans. They are very good, but bulky. I didn't want to print a ton of pages for students. This is a resource I made by compiling a few key parts into a smaller document. The content is built from their publicly available work, just restructured and pared down. There is 1 page of backg

In this review and practice activity, students sort out the major events of protein synthesis to put them in the correct order. A low prep, hands-on, minds-on task to reinforce student learning! Answer key is included.

Macromolecules - it's a big unit about big molecules! It's important that you can provide concise, quality review for your students. This table helps students identify key information they need to know about the four groups of macromolecules (carbohydrates, proteins, lipids, nucleic acids). Print it on 11x17 for a large graphic organizer - a perfect test study guide for your students to complete. And it's editable! Everybody loves a quality FREEBIE! :) Happy teaching! ~Science Classy ~ .

Here is a great task to review cell parts and their structures and functions! The descriptions for the cell parts in this activity are based on the Campbell Biology textbook (Chapter 6 in 10th ed). This is a cut-and-sort paper activity - set up to be printed on 11 x 17 paper. Students cut out mixed cards that include structure and function information for major cell parts. Then they sort the cards out onto a blank table. Once their answers are confirmed, pieces could be picked up to be re-u

How do organisms regulate and maintain stability?? Homeostasis!! Homeostasis is a key concept in Biology. This FREE resource is designed to help build towards NGSS HS-LS1-3: Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis. The included graphic organizer and teacher notes contain suggestions on how to use the graphic organizer, including examples of homeostasis in humans.

The science show Paradigms from the creators of YouTube's MinutePhysics, MinuteEarth and Veritasium debuted in March 2018! This resource is a worksheet for students to use while viewing Episode 1: The Science of Seeing. It includes short answer and fill-in-the-blank questions. On the back is a visual activity - students can "experience" their blind spot in each eye using a simple paper exercise. It is a neat activity that closely links to the content in the video. It could also be used as

As part of the Mole Day celebration on 10/23 each year in my classroom, I set up a nacho bar and give it an Avogadro twist of course! Students love it! To amp up the festiveness and bring out the mole day theme, I created table signs to place next to the chips, guacamole, salsa, and queso. Just print and go! Enjoy! Here's a fun Mole Day Banner to greet students as they enter the room on Mole Day!
