Supplement Your Lessons on Plant Structure and Function

What does it take to teach about plants in your biology class?

It takes determination, fortitude, and as many top-notch materials as you can find!  One of my Dad's favorite sayings was, "You can lead a horse to water, but you can't make him drink."    This saying runs through my head each year when I begin to teach my units on plants to my high school biology students. I'm pretty sure that if I asked my students at the end of the year which topic was their least favorite..... they would all say plants! As biology teachers, we have to cover this material.  Our very existence depends upon these lovely living organisms.  I have found that my students love growing plants, and labs involving living specimens, germination of seeds, growing plants under various conditions helps to raise the interest level among my students just a bit.

For those of you who have been waiting, I have just put the final polish on the warm ups and bell ringers that I use with my students.  This set contains 28 student pages and covers everything they need to know about plant structure and function.  Here are some highlights in pictures:





In more detail, these warm up pages will cover the following concepts:
  • Introduction to plant anatomy: Main organs of the plant, specialized organs of the plant.
  • Types of plant cells: Parenchyma, collenchyma, and sclerenchyma.
  • Tissue systems of a plant:  Dermal tissues, vascular tissues, and ground tissues.
  • Vascular tissues:  Xylem, vessel elements, tracheids, phloem, sieve tube elements, companion cells.
  • Meristematic tissues, apical meristems, lateral meristems, primary and secondary growth.
  • Roots:  Functions of roots, taproot system, fibrous root system, meristematic region, region of elongation, region of maturation, epidermis, cortex, endodermis, pericycle, root hairs, root cap, adventitious roots, differences in monocot and dicot roots.
  • Stems:  Functions of stems, nodes, internodes, buds, bud scales, terminal and lateral buds, epidermis, vascular bundles, pith, cortex, differences in monocot and dicot stems, cork, cork cambium, heartwood, sapwood, bark, vascular cambium, tubers, bulbs, corms, and rhizomes.
  • Translocation and transpiration.
  • Leaves:  Functions of the leaf, petiole, blade, veins, differences in monocot and dicot leaves, epidermis, cuticle, palisade cells, spongy cells, mesophyll, stomata, guard cells, gas exchange in leaves, simple and compound leaves, types of specialized leaves.
  • Thinking critically:  One page of critical thinking and problem solving questions about plants.
  • 6 pages of review:  Short answer, Modified True False, Multiple Choice, Fill in the Blank, Review the vocabulary, and What’s the relationship?

Amp Up Your Unit on Plants!

Ginkgo

It's time for your unit on plants.  Excited or dreading it?

As I sat down to begin the writing of this post, my initial thought was to lead with, "I just love teaching plants!"  And then it occurred to me that I begin almost all of my blog posts on biology topics in the same way.  But the truth is.... I am excited to begin teaching almost any topic in biology. I love them all!  I am sure that I have a least favorite unit to teach, but I would have to give that some thought to determine which unit it is. That is probably a topic for another blog post.....

So back to plants.  Having taught school for over 30 years, I have taught thousands of students and have interacted with many, many teachers during this time.  What I know is this:  Students don't like studying about plants (too boring!) and teachers don't like teaching about plants (students don't like it!) As a result, I have noticed that many middle and high school life science and biology teachers will either:

  1. Leave plants out of the curriculum entirely, or ...
  2. Skip through it too quickly, leaving out the depth that this unit deserves.

I find plants fascinating.  And because I do, I look for ways to make it interesting for my students.  Not the topic of this blog post, but have you ever tried the C-Fern labs from Carolina Biological?  My students literally shout with excitement when they see (using a microscope) the sperm cells swimming to the egg and the frantic mob of sperm that ensues around the egg.


Students love lab work and it definitely helps makes the class more interesting and exciting, but we all know that the "down and dirty" classroom days are needed to teach the information to our students.  I developed this set of 34 warm up / bell ringer / interactive notebook pages to use with my students while teaching about plant evolution and classification.  I am really excited about this set, and I feel that it is one of the best sets that I have written.


  • If you complete these pages with your students, I guarantee that your students will come away with a solid foundation and knowledge base about the evolution and classification of plants.
Click image to view product in my TpT store.

  • These pages are NO PREP for the teacher!!  I have done all of the prep work for you. You can spend more time concentrating on your teaching.
  • Don't use these pages the same way everyday.  Use some as warm ups, and others as homework assignments.  Some will make great quizzes.  I like to add a page or two of these as a lab station while carrying out our plant experiments.  While lecturing, I will break up the lecture time by having my students complete one of the pages for review and reinforcement.

What topics are covered?  These 34 warm up pages cover the topics commonly found in an introductory unit on plants.  Highlights include: Characteristics of plants, the plant life cycle, alternation of generations, the evolution of plants, the transition of plants to land, classification of plants, nonvascular and vascular plants, the bryophytes, the liverwort life cycle, the moss life cycle, the fern life cycle, the seed plants, gymnosperms and angiosperms.

What topics are not covered?  Plant structure and function, plant responses, and plant reproduction will be covered in future warm up sets. Stay tuned!

Thanks for stopping by, and have fun teaching!

5 Free Lessons to Leave in Your Science Sub Folder




Prepare your sub folder NOW for your unexpected absence!

We all know this story.  We have lived this story over and over and over in our teaching careers.
  • It is 4:30 am and you wake up to a very sick child.  You have to call by 5 am to get a sub.
  • You are already running late.  On the way to school, you have a flat tire.  There is no way you are going to make it in time.
  • While at school, you get an emergency call, and have to leave immediately.
  • And occasionally, even WE (teachers) get sick and need to see a doctor.
  • How many times have you said, "I would rather go to school than have to make out plans for the substitute teacher?"
Such is the nature of life.  There are always going to be unexpected events in our lives that we have no control over.  What you do have control over is how you handle them.  Do you really want to be scrambling around in the dark at 4:30 an trying to put together some materials to send to your substitute teacher?  Well, I must admit, I have been that teacher.  And you have, too!


Let's change that right now.  Here are 5 FREE lessons that you can download, print, and leave in your sub folder.  When the unexpected happens to you, you can remain calm knowing that your students will have quality lessons to complete in your absence.  Of the 5 lessons listed and linked below, 4 of them can be used in any type of science class.  If you teach, for example, a life science class and a physical science class, you can leave these four lessons for both classes.

So here they are.  Don't procrastinate.... go ahead and click on the links and print these lessons out!  They are free, so what do you have to lose?

1.  GRAPHING:  The need to review and reinforce graphing and data analysis skills is constant with our students.  Truly, this is the subject for another blog post!  Our students can use all the practice they can get, so why not have them practice while you are away from school?  In fact, if our students completed this activity several times during the year, it would be to their advantage!  In this activity, students are given data that must be graphed, followed by a set of thought-provoking and critical thinking data analysis questions.


Click image to download.

2.  SCIENCE INFORMATIONAL TEXT GRAPHIC ORGANIZERS: Here are two graphic organizers that can be used with almost any type of science text.  There are many great science news articles that can be duplicated and left with these graphic organizers in your sub folder.  As the students read the text, they will compete the graphic organizers.  Again, practice makes perfect, and our students can use all the practice they can get in learning to read and comprehend science informational text.


Click image to download.

3.  STUDY SKILL GRAPHIC ORGANIZER:  Want to leave a sub plan that covers what you have just been teaching?  This is a "compare and contrast" graphic organizer.  I use this single page all year long in my science classes.  Whatever it is that you have been teaching in science, I am quite sure that it contains concepts that can be compared and contrasted.  For example:  Students might compare and contrast photosynthesis to respiration, mitosis to meiosis, vascular plants to nonvascular plants, the three chambered heart to the four chambered heart or prokaryotic cells to eukaryotic cells.

Click image to download.

4.  DNA INFORMATIONAL TEXT WITH GRAPHIC ORGANIZERS:  This download has everything you need to leave an informational text lesson for your students.  Watson and Crick wrote a famous one page paper on the structure of DNA.  (This paper is in the public domain.)  This lesson provides the article, and the graphic organizers.  This is still a perfect lesson for a sub even if you are not covering DNA in your class.  The idea is that students get practice reading scientific journal articles. The graphic organizers help them read for understanding.

5.  GENETICS MONOHYBRID PRACTICE PROBLEMS:  This lesson is best suited for life science or biology classes.  Students are given a two-page worksheet of monohybrid, or one factor, genetics problems.  This is a great review for end of course testing!

As already stated, the above 5 lessons are free.  Go ahead and download them all and check them out.  I am certain that you will find them suitable for use as emergency lesson plans in your science classes. After all, this (<---) is what we hope for our students in our absence!


14 Ways to Use Task Cards in High School Biology


Instruction?
Reinforcement?
Retention?
No Problem!!


Task cards have quickly earned a prominent spot in my high school science classes.  I was slow to the party, thinking that task cards were a tool used by elementary teachers.  They couldn't possibly be of any use in my high school classes, right?  I could not be more wrong!

I think the thing I love best about task cards is that my students never complain about them, and in fact, even ask for them.  Teen agers will do anything to avoid school work, but my students have fully accepted the fact that the task cards have helped them study for tests and have improved their grades.

For those who might be unfamiliar with task cards, here is a quick description.  A task card is usually 1/4th the size of a sheet of paper, and usually printed on thicker paper.  I laminate them so that I can use them year after year.  Each card contains only one task or question.  For students who are easily overwhelmed by too much material or difficult concepts, task cards are a wonderful solution.  The student has a card in their hand with only one task or question.  They must complete the one task before moving on to the next.  It allows the student to focus and concentrate on only one thing at a time, rather than being presented with a long worksheet jam-packed with questions or problems.

So without further ado, here are 14 ways you can use task cards in your high school science classes to improve instruction, reinforce concepts and increase retention of the material you are teaching:


1.  Lab Stations:  This is my personal favorite.  Students of all ages get tired of sitting in a desk all day.  My students really enjoy being out of their seats and moving about the room.  I place 2 to 3 task cards at each lab station and have the students rotate through the stations.  This saves paper and printing since only one set of task cards is needed for the class.


2.  Competitive Game Formats:  Use the cards in a game format.  Divide the class into teams.  Place the task cards face down in a basket.  A team selects a card at random and must complete the task for a point.  It is a fun way to review for unit tests and high schoolers love the competitive format.

3.  Use task cards during instruction:  When teaching difficult concepts, stop periodically and check for understanding.    Ask the students to "pull out cards 16 - 20" and complete the tasks to see if they understand the material you have been teaching.  It gives the students a chance to relax just a bit and it provides an additional opportunity for them to absorb the mountain of details in a science class.

4.  Warm Ups and Bell Ringers:   
I use this one a lot!    As students enter the room, have them complete 4-5 task cards on concepts covered the previous day.  I have them write their answers on a sheet of notebook paper and collect them for a quick daily grade.  This strategy gets them to work the minute they enter your classroom, and helps them to get focused on the learning for the day.

5.  Exit Slips:  This strategy requires students to  write responses to questions you ask at the end of the class period.  It allows the students to reflect on what they have learned during the lesson and allows you to check for mastery of concepts.
 6.    Use task cards as part of your lab activities:  As students are carrying out and completing lab work, place a task card or two at their lab station and require that they include the answers to the task cards as part of their lab report.


7.  Homework Assignments:  At the end of your lesson, have students copy a few task card questions into their lecture notes to be completed for homework.  Checking student answers is a great way to start class the next day.

8.  Differentiate, differentiate, differentiate!!  How often do we teachers hear those words?  Well, task cards are the easiest way I have found to help learners of different ability levels.  By making customized sets of cards, you can give a student exactly what they need to be successful. Students can complete the cards you have given them and never know that other students have different sets of cards.

9.  Task cards are perfect for early finishers:  Task cards are not just for review and reinforcement.  They are perfect for enrichment!  When students finish their regular work early, you can give them enrichment task cards to deepen their understanding of the concepts being taught.

10.  Small group review sessions:   My students will often come in before school, after school or during a study hall period to use the task cards to review for an upcoming unit test.

11.  End of course testing:  Does your state require that students pass an end of course test at the end of the school year?  Mine does!   When reviewing for my end of course tests, I place different sets of task cards in plastic boxes and arrange them about the room,  Students select a set of cards and review through them in small groups.  When finished with one set, they select another .

12.  Tutoring:  My school offers peer tutoring and teacher tutoring after school.  Teachers and students alike will borrow my sets of task cards to use during after school tutoring.

13.  Hallway Extra Credit Display:  Post a few task cards on the wall outside of your classroom door.  Completion of the task cards can earn the student a few extra credit points.

14.  Bingo! Make a Bingo board out of task cards.  Students must complete 5 tasks in a row, column or diagonal to win.

I would love to hear your ideas and see how your students are using task cards.  I would  love to see your photos of task cards being used in your class.  Send them in (Amy1007@aol.com)  and I will feature them in a future blog post.

A Day of Giving Back


Please join us on TeachersPayTeachers.com this Sunday, December 13, for a day of "Giving Back." Many teacher/authors who sell on TpT are donating some or all of their earnings on this day to a favorite charity.  Many thanks to Erica Colon (Nitty Gritty Science) for organizing this wonderful event!

Each participating seller has chosen a charity that is near and dear to their heart, and each will be donating their earnings to their chosen charity.  All participating sellers will display this logo on their store front so that you know who is participating. You can also check out all of the participants in the linky below.



I would like to tell you a bit about the organization I will be supporting.  St Jude Children's Research Hospital is a truly amazing place.  This hospital is a leader in the research and treatment of childhood cancers.  From their web site, "Since opening 50 years ago, St Jude Research has played a pivotal role in pushing overall US pediatric cancer survival rates from 20 to 80 percent.  Our strength comes from an unparalleled integration of research and clinical care."

No child with cancer is ever turned away from St. Jude, and families never receive a bill from St. Jude for treatment, housing, travel or food.

I have had the immense pleasure of visiting the campus of St Jude many times, and can attest to the truly remarkable atmosphere.  Both of my children are healthy, but I am reassured knowing that this wonderful place exists for those who are in need.

So, on December 13, I will be donating 100% of my TpT earnings to this fabulous charity.  Click this link to visit my TpT Store.

Using Poinsettia Leaves as an Acid / Base pH Indicator

Click image to view product in my TpT store.

I LOVE this fun holiday activity!

We science teachers know that many plants contain pigments that can be used as pH indicators.  I think we have all created a stink in our homes or labs by boiling red cabbage to use the "juice" as an acid/base indicator!



Did you know that you can do the same with the pigments found in red Poinsettia leaves?

These plants contain anthocyanins, which are  water soluble pigments.  These pigments are responsible for the the red, purple, and blue colors seen in flowers, fruits, and vegetables. Anthocyanins respond to changes in pH.  I absolutely love lab activities that use items like this in the lab.  My students are often surprised and excited to discover that household items, such as the Poinsettia or red cabbage, can be used for scientific purposes.  Using the Poinsettia leaves as an acid/base indicator makes for a super fun lab activity around the holidays.

In this lab, the students will use a pigment solution extracted from the leaves of the poinsettia to establish a known pH baseline.  Students will then use this baseline to predict the pH of common household items.

The images below will give you a great idea of all that is involved with this lab. Click on any image below to view this product in my TpT store.






I hope you find this useful in your science classes.  Enjoy the holiday season!
