Mole Day Festivities!

Let's give a round of applause for Amedeo Avogadro!! Without him, we wouldn't have a reason to celebrate in our chemistry classes on October 23!!  (Oh, and we can also be thankful that he gave us a pretty nifty tool to use in our chemistry calculations.)

What are my plans for Mole Day?

I have a lab that I love, and I always do this lab on Mole Day.  It is very simple to set up, and doesn't require anything too fancy.  Students often have trouble visualizing a mole.  This lab will provide a hands-on activity that will allow our students to "see" how big a mole really is.  In one part of the lab, students are asked to write their name on the chalkboard.  They then have to determine how many moles of chalk they used in the writing of their name.  Kids love this!

So happy Mole Day to you.  I hope you have a wonderful time with your students on Mole Day.

Free Graphing Worksheet and Data Analysis Activity for Middle and High School Science

Graphing is one of the most important science skills students practice all year, but many students need repeated support with graph construction, identifying variables, and analyzing data. If you are looking for a simple way to reinforce graphing and data analysis without a lot of prep, this free activity is a great place to start.

You can grab my free graphing practice worksheet and data analysis activity here. It includes printable and digital Google Slides formats, making it easy to use for classwork, homework, bell ringers, review, or a quick science skills refresh at any point in the year.

Why graphing practice matters in science

Strong graphing skills help students make sense of scientific data, recognize patterns, and communicate results clearly. That is why graphing practice should not be limited to the beginning of the school year. Short, meaningful review activities throughout the year help students become more confident with science process skills and better prepared for labs, assessments, and data analysis tasks.

This free worksheet gives students practice creating a graph from data, identifying independent and dependent variables, and answering data analysis questions. It is a simple way to build graphing confidence while also reinforcing other important science skills.

Endocrine System Warm Ups and Bell Ringers for High School Biology

Endocrine system warm ups and bell ringers can help you turn the first few minutes of class into focused daily review while students reinforce important human body concepts. Students review endocrinology topics such as hormones, endocrine glands, feedback mechanisms, homeostasis, and endocrine disorders through short daily warm ups. A consistent warm up routine can make this challenging topic much easier for high school biology students to review, understand, and remember.

High school students and hormones? Watch out! The endocrine system is definitely a challenge to teach, but it is also a fascinating topic that students find interesting. Many students are especially curious about endocrine disorders, diabetes, pituitary disorders, acromegaly, goiters, and the way hormones affect the human body. Those real world connections make endocrine system review much more engaging and help students see why these concepts matter.

Teaching the Endocrine System in High School Biology

How much detail should we teach to high school students? Every year and every class is different, but most of my students are learning detailed information about the endocrine system for the first time. I think it is essential for students to understand what hormones are, how hormones work, and how the endocrine system helps maintain homeostasis in the body.

Students should also be able to identify the major endocrine glands and understand the basic function of each gland. Depending on the class, students may be ready for more detail about hormone action, target cells, receptor sites, feedback mechanisms, and specific endocrine disorders. I give them what they can handle, and then I build in consistent review so the vocabulary and concepts do not disappear after one lesson.

You can see the full Endocrine System Warm Ups and Bell Ringers for High School Biology resource in my TpT store.

Endocrine System Warm Ups for Daily Review

The first 5 to 7 minutes of class can easily become lost instructional time. Endocrine system warm ups help students begin working immediately while reviewing key concepts from previous lessons. This short daily routine gives students repeated exposure to difficult vocabulary and helps them build confidence before quizzes, tests, and semester exams.

I use warm ups and bell ringers in several ways. They work well as daily review activities, homework assignments, exit slips, quick formative assessments, short quizzes, tutoring activities, and test prep. They can also be added to an interactive notebook so students gradually build a useful study tool throughout the unit.

What Is Included in the Endocrine System Warm Ups?

This endocrine system resource includes 29 printable and editable warm up pages and 29 matching editable Google Slides activities. The warm ups are designed for grades 9 through 12 and work well in high school biology and anatomy and physiology classes.

The activities cover hormones, endocrine glands, hormone action, the relationship between the nervous and endocrine systems, feedback mechanisms, homeostasis, endocrine disorders, and unit review. Students review the hypothalamus, pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, reproductive glands, and other hormone-producing glands.

The resource also includes complete answer keys, a 5-page teacher guide, an editable template for creating your own warm ups, and editable templates for starting an interactive warm up notebook.

Printable and Digital Endocrine Review Options

One of the most helpful features of this resource is the flexibility. You can use the printable pages in a traditional classroom, place them in student notebooks, or assign them as homework. You can also use the editable Google Slides version for 1:1 classrooms, blended learning, Google Classroom, Microsoft OneDrive, or distance learning.

The digital version is especially helpful when you want students to complete daily review without printing. The editable format also makes it easy to adjust questions, shorten an activity, or customize the warm ups for your own class.

Build an Endocrine System Warm Up Notebook

These warm ups can also be used to create a student warm up notebook. Students complete short review activities throughout the unit and keep their pages together as an organized study guide. By the time you reach the end of the endocrine system unit, students have a collection of review pages that can be used for quizzes, tests, and semester exam review.

This format is especially helpful for students who need repeated exposure to challenging biology vocabulary. Concepts such as hormone action, target cells, endocrine glands, and feedback mechanisms become easier to remember when students revisit them in short, focused practice activities.

Endocrine Topics Covered

The 29 warm ups cover many of the endocrine system concepts commonly found in a high school biology or anatomy and physiology course. Topics include the introduction to the endocrine system, hormones, how hormones work, endocrine glands, prostaglandins, the hypothalamus, the pituitary gland, the thyroid gland, the parathyroid glands, the adrenal glands, the pancreas, diabetes mellitus, reproductive glands, sex hormones, feedback mechanisms, endocrine disorders, and unit review.

The review pages include vocabulary review, gland and hormone matching, hormone function matching, fill in the blank review, relationship questions, short answer, multiple choice, and true or false questions.

Lab Safety Tip: What You Need to Know About the Eyewash Fountain and the Lab Safety Shower

👉👉 Required Reading for the Week:

Scientific American - Danger in School Labs: Accidents Haunt Experimental Science

When was the last time you tested your eye wash fountain and your lab safety shower? Did you know that they are supposed to be flushed once a week according to ANSI standards? I think it is safe to say that the plumbed emergency equipment in our science labs is often neglected. We walk past the eyewash and the shower day after day after day, but rarely stop to inspect it. Since I have never had to pull the handle (thankfully!) on either piece of equipment in an emergency, I rarely stop to think about the routine maintenance that is required.

But I am not an expert. And while I hope this blog post puts a nagging reminder in your brain, use the links in this post to read what the experts have to say. My go-to source of lab safety information is Flinn Scientific. Read this article about the eyewash and safety shower.

Here are the basics about the lab eyewash fountain:

• The eyewash must provide a flow of water to both eyes simultaneously.
• The affected area must be irrigated for a minimum of 15 minutes.
• Keep both eyes open and rotate eyeballs in all directions.
• Regulation of volume and pressure is required to maintain a soft flow of water to the eyes.
• Location of the eyewash is important.  Travel time from a work station to the eyewash should be within 10 seconds.
• Water temperature should be "tepid" which means lukewarm. Acceptable temperature range is 78 - 92 degrees Fahrenheit.
• Weekly testing should occur to verify flow. This also clears the water line to remove dirt from the pipes.

Here are the basics about the lab safety shower:

• The shower should provide a deluge large enough to encompass the whole body.
• Remove contaminated clothing. Every second counts. Don't be modest. It will only slow you down. Remove contaminated clothing!
• The shower should deliver a pattern of water that is 20 inches across.
• Water flow should be 20 gallons per minutes at a velocity low enough to not injure the user.
• The plumbed safety equipment should be clearly marked with signs and by painting the walls and floor surrounding the equipment a bright color.

For us middle or high school teachers, words cannot begin to describe how busy we are during the school day. If your safety equipment does not meet the standards, it is time to have a talk with your school administrator. The safety of your students depends on it!

And please don't forget to take the time to inspect the equipment. No eye wash fountain should ever look like this!

Classification and Taxonomy: Reviewing Important Concepts

This Kingdoms of Life Mix and Match Game is an excellent way to review the concepts of classification and taxonomy.

When teaching a unit on classification and taxonomy, the presentation of the six kingdom classification system seems pretty easy and straight forward, right? When I ask my students what kingdom frogs belong to, I know without a doubt that they are going to say "Animalia."  For our middle and high school life science students, learning which organisms belong to which kingdom is a simple task that is quickly and easily mastered.

But when I ask my students questions like these, they will hesitate.  And often give the wrong answer.

• Name the kingdom that contains heterotrophic plants.
• Name the kingdom in which all members are autotrophs.
• Name the kingdom that contains prokaryotes with peptidoglycans in their cell walls.
• Name two kingdoms in which all members are heterotrophs.
• Name the kingdom that contains organisms with specialized cells, tissues, organs, and organ systems.
• Name the kingdom in which all members have cell walls composed of cellulose.

I have fallen in love with using mix and match card sort games as a way of reviewing and reinforcing concepts in my science classes.  My latest creation is this Kingdoms of Life Mix/Match Game.  

Students are given 6 larger cards.  Each large card has the name of one of the six kingdoms in the 6-kingdom classification system.  The set also has 80 "answer cards."  Students are tasked with matching the answer card to the correct kingdom.

The game comes with student answer sheets and a 7-page teacher guide.  The student answer sheets are optional, but I always have my students record the answer card statements on the answer sheet.  Writing is a way of studying, and the answer sheets make a great study guide for the unit test.  The teacher guide has lots of suggestions for how to use the game, directions for set up and implementation, and of course, a complete answer key.

The game is perfect for all life science students of different ability levels because you can easily differentiate the game for any group of learners.  By selecting which answer cards to use, you can make the game perfect for any ability level.
