Each of these slides deals with an individual organelle and displays a diagram along with labels of the structures. The most useful components of this slideshow are the summaries of functions and descriptions of how the organelles are...

When DNA research first began, it required almost an entire day to extract the molecules from a cell nucleus. Now it requires less than an hour. Scholars learn about the early theories of DNA with an online interactive, videos,...

Your students should enjoy this slideshow which includes some basic definitions about the atomic structure of atoms. In fact, this presentation would be best-viewed before giving details and diagrams of neutrons, protons and quarks. The...

Chromosomes contain keys to history including links from royalty to Neanderthals. Young scientists learn about Ivan Wallin's research into chromosomes with an animation and videos. Then, the concept connects to mysteries related to...

Incorporate multiple facets of the cell into your next high school lab! Through an introduction to cell organelles, class members observe each cell type and draw visuals to further demonstrate understanding of cellular processes in both...

In 1993, Phillip Sharp and Richard Roberts won the Nobel Prize for their discovery of split gene theory. Learn about the breakthrough with the help of an online interactive. Hear both scientists explain it in their own words, watch an...

How do cells know when to replicate, transcribe, and stop? James E. Darnell, Jr. shifted from studying medicine to biochemistry and decided to address this mystery. Learn about his research, discoveries, and the impact on future medical...

High schoolers plot particle sizes of common airborne materials on a log scale. They read an article on particle size and its relationship to the ability to pass through the lungs, into the bloodstream, and eventually into the cells...

Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements,...

Rings and golden nuggets contain the element gold, but how small can you break it down before it is no longer considered gold? A helpful presentation explains the basics about atoms, elements, and isotopes through a presentation.

What's smaller than a kiwi seed? Atoms! Basic atomic structure is detailed for beginning chemists in a light-hearted animation. Protons and neutrons are explained as part of the nucleus, and so are electrons that encircle the nucleus....

How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

Eight fine-quality slides depict the cells that make up plants. Viewers will see colorful microscope views of the nucleus, cell wall, vacuole, chloroplasts, tracheids, and pollen grains. The resource would apply in either a cell...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

The dynamics of a city can have a drastic effect on the weather. A hands-on lesson asks learners to build a model to illustrate how city pollution provides a nucleus for condensation. The greater the pollution, the greater chance for...

Five pages provide thorough coverage of three protozoans: euglena, amoebae, and paramecia. For each, junior biologists read factual text, label the organism, and write answers to several questions. This neatly organized assignment is...

In this countdown challenge worksheet, students find the 10 common elements from the human body, earth's crust, and ancient times and color code them. Students fill the atomic number of the elements in a given periodic table.

Humans have only inhabited the earth for a fraction of the time that life has existed. Young scientists explore the facts about the emergence of life on Earth with an interactive resource. While highlighting different types of life, the...

Fifth graders continue their investigation of the plate tectonics cycle with an exploration of the movement of Earth's crust. During the lab, young geologists conduct an experiment to discover the result of different types of...

In this radioactivity activity, students answer 40 questions about half life, isotopes, radioactive decay, the uses of radioactivity, nuclear equations and the scientists associated with radioactivity.

Here is a quick puzzle-style activity for your aspiring astronomers. A code is printed at the top of the page and learners use it to fill in the blanks describing different phenomena or objects in outer space. The material does not even...

Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.

In "Nuclear Arthmetic," first-time physical scientists examine atomic structure and the periodic table of elements. The are given the formula, "N = A-Z," in which N is the number of neutrons, A is the atomic mass, and Z is the atomic...
