DNA here we come!

I started teaching one of my favorite topics today:  DNA, RNA and protein synthesis.  I am always fascinated by the complexity, simplicity, and beauty of DNA.  Try as I might, it is sometimes very hard to get the students to be as amazed by it as I am.  So being the perfectionist that I am, I spent HOURS AND HOURS putting together this PowerPoint presentation.  It has 61 slides.  Here are a few photos....





I hope to WOW them with the soap opera drama of Watson and Crick tomorrow.  Want to take a look at my Powerpoint?  Check it out!  It also includes a set of notes for the teacher and a set of notes for the student.

I made the newsletter!!

Each week TeachersPayTeachers.com puts out a newsletter.  The newsletter is packed with information about all sorts of subject areas and covers all grade levels.  It comes out every Sunday.  One of the best features about the newsletter is that it always includes links to "10 FREE downloads".  These are 10 great products that are being offered for free.  They are the complete product, not just a preview.

You can sign up to receive the weekly newsletter by clicking here, TeachersPayTeachers.com.

Today, one of my many FREE items is listed in the newsletter.  I usually write about my Biology I class, but most of my school day is spent teaching Advanced Placement Biology.  My students have to take the national AP Biology exam in May.  If they score well enough, they can earn college credit for their efforts. So we are very busy learning new material, but also trying to review old material.  I use PowerPoints packed with questions to help them review.  Each day I try to spend a few minutes going through one of these reviews.

One of these review PowerPoints is in the newsletter today.  It is a review of Carbon and Organic Compounds. I hope that it will help someone out there!

Have a great week end!

Bye, Bye Genetics!

Well, my Biology I kids are finished with their unit on genetics.  At the end of the week we covered sex linkage, pedigree tables, and had a unit test on Friday.

Sex linkage practice problems
Quiz on sex linkage and multiple alleles
Pedigree tables
Genetics Unit Test

Before the unit test, my students really enjoyed playing PowerPoint Genetics Jeopardy!

I have put together an entire biology unit on a CD. This unit contains at least 3 weeks of materials depending on how many lab activities you want to do. The title of this unit is "Genetics". This unit has everything that a Biology teacher needs to teach a unit on genetics to Biology I students. You will receive a 61 slide powerpoint, teacher notes, student notes, 2 labs, 1 jeopardy review game, 5 quizzes, 7 practice problem worksheets, 1 crossword puzzle and a unit test. 

All answers are included.

Topics covered are:
1) Extensive coverage on the work of Gregor Mendel
2) Mendel's Laws of Dominance and Recessiveness, Segregation and Independent Assortment
3) Using probability and Punnett squares to work genetics problems
4) Monohybrid or one factor problems
5) Dihybrid or two factor problems
6) Summary of Mendel's principles
7) Genes and environmental influences
8) Incomplete Dominance
9) Codominance
10) Multiple Alleles
11) Polygenic Inheritance
12) Sex Linked Genes
13) Pedigree Tables

There will be a shipping and handling charge of $2.00 to cover postage, new CD and hard case, and bubble mailing envelope.   Take a look at my genetics unit by clicking HERE


So what is coming up next for my darling biology I students?  Well, on Monday we start my unit on DNA, RNA, and Protein Synthesis.

The Corn Grew!

We have been out of school for a week for our Spring Break holiday.  A week prior to the break, my biology I class started growing some corn seeds for our lab, The Effect of Environment on Gene Expression.  This lab requires 2 observations after the corn starts to grow.  We did the first observation over a week ago.  Today we did the second observation, collected our data and wrote our lab reports.  We expected to get a 75%:25% ratio of green stems to albino stem.  Our actual data came very close to this.  Here are a couple of photos of the growing corn:



The students really love doing this lab.  Many of them took their corn home with them!  A good extension of this would be to do a chi-square analysis of the data.  This particular class is not prepared for that kind of data analysis, so I did not do it with this class.  Maybe next year!

After we finished the lab, we did a practice problem worksheet on Codominance and Multiple Alleles.  I am giving a quiz on these types of problems tomorrow.  Good luck everyone!

It's Thursday and Time for the Round-Up!

If you are reading this, I assume you are looking for ideas in science teaching, especially for biology.  But I want to tell you about another blog that you should follow.  It is called Teacher 2 Teacher.  Contributions to the blog are made by an assortment of truly awesome educators.  You will find articles each week written by different teachers.  And the best part is the Thursday Round-Up.  Each week, a group of 20 teachers places one of their best products on sale.  These products cover a wide range of subject areas and age groups, but they are all on sale from Thursday morning through Saturday night.  This week has more math and science products than ever before.  Way to go teachers!

Here is the product that I have on sale:     The Ultimate Lab Safety Bundle

Come back tomorrow.  I have been helping a friend of mine develop some products for a microscope unit.  I am putting the finishing touches on several new products and will list them here tomorrow.

Microscopes? At this time of the year?

My Biology I students and I are still slugging away through genetics, but I took some time out of an already really busy schedule to help out a friend.  My friend has taken an interim teaching position for a teacher who got sick and cannot complete the year.  The position is for 7th grade middle school science.  The students have not had a great year;  evidently the regular teacher has missed quite a few days this year. My friend is not a certified science teacher, and is in need of direction, guidance, and most importantly materials to teach with.

It is an odd time of year to take up the microscope, but the students have not learned this material, so I guess there is never a bad time to learn something you don't know!  I wrote this powerpoint for my friend to use with her new students.  It will help her get through a few days, and I have also supplied her with all of my supporting materials.

I hope that some of you will find something here that will be useful to you as well:

Genetics, genetics, genetics!

We continue to move through the study of genetics in my standard Biology I class.  We have now completed nondominance problems, codominance problems, and problems with multiple alleles.  The key to getting this across to the students is practice, practice, practice!

Here are links to the practice problem worksheets I use to teach these genetics problems:

I love Genetics!!

My Biology I class is continuing their study of genetics.  We are working through my powerpoint on Genetics:  Genetics Powerpoint with Notes for Teacher and Student.  This powerpoint has everything you would need to teach a genetics unit to a Biology I class:  Gregor Mendel, laws of genetics, vocabulary, monohybrid crosses, dihybrid crosses, nondominance, sex linkage, multiple alleles, blood groups, geneology tables, etc.

The students in my Biology I class are of such varying abilities.  Some are very bright and should be taking Honors Biology.  Others are very slow learners with learning disabilities.  It makes it quite a challenge to teach a group of such varying abilities.  Everyone seems to have mastered a basic understanding of Mendelian genetics.  We have worked many practice problems on dihybrid crosses and we had a quiz today on the dihybrid cross.

Dihybrid Practice Problem Worksheet

Tomorrow we will begin to learn about Incomplete Dominance or Nondominance.

Genetics is so fun!

The seeds have been planted for the genetics lab called The Effect of Environment on Gene Expression.  The students had a great time planting the seeds, and are having fun watching for the first signs of germination.  Hopefully, in a week or so, the plants will be big enough to classify them as green or albino.

Today, we are starting the monohybrid cross.  Genetics is one of my very favorite topics to teach to students.  It is so easy to keep their attention.  Over the next two days, I will be using several handouts that I have developed on the monohybrid or one factor cross.

Check this one out since it is FREE!!!  Monohybrid Mice!

And I will also be having my students complete these:
