- Time management is so important! If you are not careful, this can consume way too much of your class time.
- Utilize to the best of your ability, the first 5-10 minutes of your class. Don't get bogged down in classroom chores. Get your students right to work every single day. A short warm up or bell ringer each day will get students working, while you are taking care of "stuff."
- Reviewing a small amount of information each day has increased retention of information for my students.
- The best comment ever from a student? "These have really helped me remember the information for the test."

Real Science Teaching. Real Classroom Experience.
I’m Amy Brown, a veteran high school biology and chemistry teacher, wife, and mom who understands the daily reality of lesson planning, grading, meetings, and everything in between. I know what it feels like to have too much to do and not enough time to do it.
After decades in the classroom, I’ve created rigorous, classroom-tested biology and chemistry resources that save you planning time while still delivering strong, meaningful science instruction. Every lab, activity, and lesson is designed to move students beyond memorization and into real scientific thinking.
If you want your students excited about science and thinking deeply without spending your entire weekend planning, you’re in the right place.

Teaching Fungi? Interactive Notebook Pages and Warm Ups Will Help!
It's February ... And That Means Daphnia Love is in the Air!
I soooo look forward to this lab each and every year. Measuring the heart rate in Daphnia is FUN, is fairly easy to do, allows our biology students to work with living organisms in the lab, and perhaps most importantly, it provides an outstanding situation for having our students design and implement their own experiment.
Are you nervous about "student-designed experiments"? Don't be! If properly trained and instructed on the front end, the students will surprise you with their creativity and passion for designing an experiment. But I am getting ahead of myself. Let me go back to the beginning....
Daphnia are tiny crustaceans, closely related to a shrimp. They are often called "water fleas." They are small, but not microscopic. They can be seen with the naked eye, but you will need a dissecting microscope to view the beating heart. Daphnia can be purchased from any of the companies that sell lab supplies and equipment. Since Daphnia are arthropods, they demonstrate the three major arthropod characteristics: exoskeleton, jointed appendages, and segmented body. The exoskeleton is clear, allowing the student to easily view the heart. Daphnia are ectotherms and their body temperature changes with the surrounding environment. This further means that there is a direct relationship between the internal body activities and the external temperature of the water in which it lives.
This sets the stage for the first part of our experiment. I have my students carry out an experiment where they measure the change in heart rate when Daphnia are exposed to different temperatures. I provide the procedure, and the student simply follows the instructions and carries out the lab. The Daphnia are exposed to three different temperatures, and the student counts the number of heart beat per minute in each environmental condition.
Students carry out my procedure, graph their results, and answer my questions. On Day 2, the fun begins! It is time for the students to design their own experiment! They are asked to design an experiment to test the effect of caffeine on the heart rate of Daphnia. The students must state a hypothesis, describe their experimental and control groups, carry out the experiment, collect their data, graph their data, and come to a conclusion based on their data.
The student-designed experiment will take some time. I require my students to write their experiment and submit it to me for approval before they begin. Once approved, they carry out their experiment and write a formal lab report. The best learning occurs as the student is carrying out their experiment. They invariably realize that their procedure is flawed, and they must revise, revise, and revise until they get it right.
For my honors and AP students I require that they also complete a worksheet on how to calculate the Q10 temperature coefficient.
And this is what we do to celebrate Valentine's Day in my biology classroom. Happy Valentine's Day everyone!
In my TpT Store: "Measuring the Heart Rate of Daphnia" contains handouts for all parts of this experiment, including the student designed experiment and the Q10 worksheet. Teacher Guide included.

Secondary Smorgasbord #3 Out of the Deep Freeze: Revisit My Planet Earth Awards
January Blog Hop
Once again it is time for the Secondary Bloghop event. The theme for this month is "Out of the Deep Freeze" and is about an idea whose time has come (could be something we are currently working on), or a product that doesn't get the attention we'd like it to get and should get because, darn it, it's really good!
A "brain-break" is a 2 or 3 minute break away from the topic currently being taught. It is a couple of minutes where the student can relax, and it relieves the tension of a very complex lesson. I am still a teacher who wants every minute to count. So during a "brain-break" I usually throw out a bit of science trivia. These are just fun and interesting facts that teach the student about the amazing natural world we live in. Over the last few months my "brain-breaks" have consisted of the Mother Nature Awards for Planet Earth.
Here is an example:
These are PowerPoint slides. I insert one of these slides into a PowerPoint on cellular respiration or photosynthesis or enzyme-catalyzed reactions. My students have come to expect these little surprises and they get excited when one of these pops up into my otherwise overly technical lecture. This is fun, it teaches a bit about the wonders of nature, and best of all, it gives the student just a minute to relax and get focused again before I launch back into the real topic of the day.
After a slide has been viewed, I print it, laminate it, and place it on the wall in my classroom. I have been very pleasantly surprised at how often students stop by the wall to look at the Mother Nature Awards.
I have put together a group of 20 of these awards and placed them in my store on TeachersPayTeachers.com. There are two product listings, one for Grades 2-5 and a separate listing for grades 6-12.
The listing for grades 2-5 comes with a set of activity worksheets (42 pages) for the students to complete as the PowerPoint slide is being viewed. The finished worksheets can be put together to make a great Mother Nature Award book.
The listing for grades 6-12 comes with a worksheet for students to conduct their own research to develop a PowerPoint slide for a Mother Nature Award of their own choosing. This makes a nice homework assignment for a grade, or for a great extra credit opportunity.
Don't forget that Earth Day is coming up soon. The Mother Nature Awards are a perfect Earth Day activity.

Insects: A Dichotomous Classification Key Activity
There is just something about working through a classification key that is fun. I love them, the students love them .... and the result is a classroom activity that is stimulating, educational, and ... well, it is just FUN!In my 30+ years of teaching biology, I always look forward to my unit on classification and taxonomy. As a result, I have developed quite a few teaching materials and lessons on this topic. After posting these materials in my TpT store, I began to get more and more requests for additional activities that use a dichotomous classification key. Well, here is the newest addition to this type of activity.

There are actually two activities in this product. Students begin by using the included dichotomous key to the insects to identify 9 different insects. Second, students are given pictures of a representative organism from each of the five classes of the Phylum Arthropoda. Students are asked to make good observations and develop their own dichotomous key for these arthropods. The dichotomous key and the two pages of pictures can be laminated and used year after year. Student handouts include 2 pages for their written work. Analysis and follow up questions are also included to extend the activity.
I wrote this activity in response to requests from many upper elementary and middle school teachers. Therefore, I feel this activity is most appropriate for grades 4-7. However, my experience teaching high school tells me that my first year biology students will love this as an introduction to classification. I hope you enjoy it as much as I enjoyed developing it.

Yes, there will eventually be a"Bundle Part 2", but it is not likely to be seen until the summer of 2015.
So without further ado, here is a preview of the first bundled set of warm-ups, bell ringers, and interactive notebook pages. Click on any image below to view this product on TeachersPayTeachers.com.
Science Stuff: Top 5 Blog Posts of 2014
I looked at each blog post and picked out the top five that had the highest number of hits. Already this is flawed..... A post written in January 2014 had a lot more time to receive hits than a post written in December of 2014. Nonetheless, I stuck with the original plan and went with the five getting the most hits.
Of the five, three of them were no surprise. They covered topics that are highly popular right now. But I was a bit surprised by the other 2.
I am very pleased with all five of these posts. I believe that each and every one of them offers tips, suggestions, and valuable information for the science classroom teacher. I may be living in a world of denial, but it is my hope that some of my ramblings have been helpful to other teachers.
