In this evolution instructional activity, students will determine the evolutionary relationships among organisms using cladograms and phylogenetic diagrams. This instructional activity has 13 short answer questions and 3 multiple choice...

In this atomic structure activity, students select answers to 8 fill in the blank questions on subatomic particles from the drop down box.

If the only support you are in search of is lists of vocabulary terms, this presentation may fit the bill. Slides simply list terminology. These categories are included: hierarchy of structural organization, cell functions, cell...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

Seventh graders describe the basic structure of the DNA molecule. They identify what an inherited trait is and how it can be determined by one or more genes. Finally, 7th graders identify that plant and animal cells contain several...

Life science laureates choose a plant or animal cell to construct a model of as an at-home project. This handout provides guidelines, suggested materials, and a grading rubric for their reference. A full-page letter to parents is also...

Learn about damage associated with earthquakes and materials that best withstand a quake. A lab engages class members in the experimental design and construction of sturdy structures that can endure various earthquake...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

How do changes in DNA affect an organism? Scholars explore chromosomes, genes, DNA, and mutations by modeling the DNA of a strawberry. They build a DNA model, then manipulate it to show how changing the genes transforms the strawberry...

After comparing earthquake and volcanic hazards to one another, fifth graders take a closer look at damage associated with a volcanic eruption. They then create a simulation of mudslides due to a volcanic eruption. Using different...

Roger Kornberg, the oldest son of two biochemists, won the 2006 Nobel Prize in Chemistry. Learn about Kornberg and his scientific research with an animation, videos, biography, and an applied problem-solving activity. A summary and...

Searching for simple ways to teach mitosis to high schoolers? Using colored chalk and onion root tips, pupils visually demonstrate what they view when looking through the lens of a microscope. There are also various ways to expand the...

In this atomic structure learning exercise, students answer eleven short answer questions about the structure of atoms including the number of protons, neutrons and electrons. Students indicate the differences in isotopes of atoms and...

Four diagrams of the atom and their subatomic particles and structures are given here and students should be able to complete the labels need to define the structures shown. The main structures defined are protons, neutrons, electrons,...

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

Students experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.

Coloring pages showcase microbes—bacteria, viruses, and protists. Scholars have the option to download a coloring book and scavenger hunt or color the page directly on the computer. Three paragraphs describe each microbe. 

Students identify magnification by first using a magnifying glass and then with photos taken through a microscope. They complete a handout that leads them through each activity stated. Finally, students use their microscope to view a...

Trace the sequential process of the developing theories of atomic structure in the early 20th century, show, in historical development, how scientists "know" things, how experiments are set up and how interpretations are drawn from them,...

Sixth graders identify, locate and describe the function of the parts of a cell. In groups, they state the five stages of mitosis and put them in the correct order. They are introduced to the structure of DNA and mRNA and how they...

In this DNA: structure and replication learning exercise, students fill in the blanks about the structure of DNA and replication of DNA. Students sketch several diagrams of DNA at different stages.

Students are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory

Students explore the parts of the cell. In this cell lesson, students use foods to create cell models that represent the nucleus, cytoplasm, cell membrane, mitochondria, ribosomes, vacuoles, endoplasmic reticulum, and Golgi bodies...

The many slides and images in this PowerPoint are clear and relevant to the detailed content covering the details of DNA structure, replication, cell differentiation, and mutation on an advanced level. The slideshow summarizes all of the...
