Gene Regulation can be one of the most confusing concepts to each secondary science and college level biology classes. This power point breaks both prokaryotic and eukaryotic regulation down into simple terms that can be easily understood. The last slide asks the students to create a contrasting chart to write the differences of gene regulation between prokaryotes and eukaryotes. Topics: Prokaryotic regulation Lac Operon Repressor Operator Eukaryotic regulation Transcription complex Repressor Histones RNA polymerase TATA Box

This graphic organizer covers the precursors to teaching stoichiometry. The students begin reviewing atomic mass, molar mass, moles and Avogadro's number. Each definition is coupled with practice problems for the students to solve. The next concept is percent composition. there are instructions on how to solve percent composition from the compounds formula and from masses given. The last two concepts covered are empirical formulas and molecular formulas. Again there are practice problems you can solve with your class. I have included detailed teachers key and the foldable easily fits into a composition notebook or spiral ring notebook to complete an interactive notebook.

This Animal kingdom power point not only covers main characteristics of animals but also allows students to see how marching through the animal kingdom can give insight into how the kingdom evolved.

The power point covers the electromagnetic spectrum, light, photons, waves and their characteristics. the relationship between frequency, wavelength, and the speed of light are introduced with the formula for speed of light. Calculating the energy of the electromagnetic waves is also covered with introduction to Planck's constant and the energy formula derived using the constant. How we see light is presented along with slides for each type of electromagnetic ray and how they can affect human health. I also have a slide on cosmic rays since they have the most energy of all electromagnetic rays.

In this power point the students will have a short review of mitosis and cover vocabulary specific to meiosis. Next the students go over crossing over using terms such as sister chromatids, homologous chromosomes, synapsis, tetrad, chiasmata. The detailed meiotic steps also discuss what is happening with the quantity of genetic material and each phase of meiosis is detailed.

This power point presentation covers all he evidences of evolution and Charles Darwin's importance. Topics covered are; Charles Darwin, natural selection, Finches, Galapagos tortoises, giraffe evolution, DNA evidence, embryology, homologous organs, vestigial organs, fossil record, and biogeography. Students will be able to identify the five evidences of evolution and understand how scientists use these to determine how species evolved over time. Students will understand that evolution happens to populations not individuals.

This extensive editable power point goes through the Chordate phylum and presents while giving an detailed explanation of the adaptations that evolved which led to the diverse sub-phylum of the vertebrate. Students will learn about how cephalization, kidney development, the skeleton, amniotic egg, hair, fur, placenta and many other traits allowed for the different fish, reptiles, birds and mammals to evolve. This is an excellent resource for Honors, college level and AP Biology classes. It is also organized in a way in which students should be able to seamlessly create a cladogram from it. You could also print the slides out as cards and have the students try to arrange them in evolutionary order.

The RNA Power point chronologically presents the properties of RNA as they were discovered. The differences of the structure of ribose and deoxyribose and the differences between DNA and RNA nucleotides. Students will learn how to transcribe DNA into RNA and the function of the three types of RNA: messenger RNA, transfer RNA and ribosomal RNA. The RNA foldable covers the same topics and can be easily taught along side the power point or separately. It only requires one sheet of paper and easily fits into a composition notebook or spiral notebook. Excellent introductory lessons for DNA processes, DNA replication, and protein synthesis.

This Cryptozoology Dichotomous Key is a great secondary science Halloween activity or end of year wrap up when the AP Biology or state exams finish. We all know how antsy high school students get when Halloween comes around. You can keep them entertained with taxonomy over monsters, beasts, mythological creatures and strange diseases. This dichotomous key is a mixture of reality and myth. Students are given 25 organisms they need to identify. I also included two suggestions for extension activities. I usually use this as a cooperative lesson with my students paired up so they can work the dichotomous key together. I upload the power point to the class website and have my students work with a partner on a laptop.It is a lot of fun to hear them talk about each situation using educational dialogue. This is also a good activity for flipped classrooms. If you do not have a set of classroom laptops or ipads you can also print the power point slides and place small groupings around the room and turn it into a centers activity. You could also print the slides out as class sets.

I have bundled two versions of this genetic disorders worksheets. They both cover the same chromosomal diseases but one is short answer and the other asks the students to describe the disease symptoms. In both sets the students are given 8 karyotypes that they need to identify by gender and figure out what chromosomal abnormalities are in each. The students can then take that information and research it online or at a library to find the syndrome's name and symptoms (long answer set). The teacher key is included for both. The students worksheets are five pages long since they include an introduction in each set. The teacher keys are four pages long for each set. The picture file is just for advertising.*

The population genetics power point covers the mechanisms of how species evolve over time. It begins with an overview of Hardy-Weinberg and then delves into genetic flow, genetic drift, bottleneck effect, founder's effect, the types of selection, the types of isolation and the types of speciation. The power point is filled with examples of the mechanisms and pictures, graphs and charts to help emphasize the concepts. The concepts are heavy within population genetics so I would advise to chunk the information up into segments instead of teaching them all the way through in one day.

Two student guiding graphic organizer fold out foldables. The first focuses on the cell cycle and mitosis. The second focuses on meiosis. There is also a free venn diagram included to help students organize their thoughts on the differences between mitosis and meiosis. Teacher keys for both foldables included. Cell Cycle and Mitosis Graphic Organizer: The foldable covers cell cycle, G0, G1, S, G2, and mitosis in both animal and plant cells. There are note taking areas for how mitosis is the driving force behind growth, development, regeneration and asexual reproduction. The foldable also covers tumors both benign and malignant (cancer). Meiosis Graphic Organizer: This graphic organizer fold out foldable first prompts the students to define vocabulary specific to meiosis. Next the students go over crossing over using terms such as sister chromatids, homologous chromosomes, synapsis, tetrad, chiasmata. If you teach AP Biology it is great for review. The detailed meiotic steps also discuss what is happening with the quantity of genetic material and each phase of meiosis is detailed.

Astronomy Ornament Activity is a fun fine motor skills activity designed for older students to have an opportunity to create a papercraft while using their fine motor skills, through writing, coloring, cutting, gluing, and assembly. There are fifteen celestial objects including an astronaut. The ornaments have a front and back. The front of the ornament is a rendering of the celestial body. The back of the ornament has questions about the astronomy element that students can answer using their books or a quick internet search. Students will color the ornaments’ fronts and backs, cut the ornaments out, and assemble them. Students can glue the fronts and back together. Another option is using cardstock between the two layers for added structural support. I am sure there are multiple other options that you and your students can come up with. These are also fun classroom decorations to hang up. I have hung some of mine from the ceiling and the students enjoy looking at them. Instructions are included as a PowerPoint presentation or pdf file.

A new twist on lab safety and equipment review. Many times we repeat the same lab safety and equipment reviews every year. Make it fun with this Lab Safety and Equipment Memory game. The students will need to match 25 pairs of cards. One card has a description and the students need to match it with a picture or explanation. The game allows the students to continuously review lab safety and equipment while having fun and being competitive. The cards are square and saved as a pdf. By adjusting your page count per printed page you can adjust the size of your cards. I suggest laminating them and keeping them year after year. I use one set per lab table. You can have the students compete within a single table or between groups.

Viruses often boggle young students' minds. They are not living so can not be called dead. This power point goes over the reasons viruses are not categorized as living, explains their methods for reproduction, the lytic and lysogenic cycles. HIV reproduction in the human body is covered in detail along with the five drugs used in its treatment. There are a few slides dedicated to Ebola / Marburg, why they are hard to find and how the primate population of the world is being affected. The latest Zika virus is also presented and why it is detrimental to developing babies in the womb. Multiple common viruses are also displayed and discussed. Students will be able to distinguish viruses from living things and understand their methods of reproduction. Students will also be able to identify viruses based on their structure. Students will also understand that viruses infect all forms of life.
