You can't tell by the title, but this is a functional periodic table of elements. Incorporating bright colors, lucid text, and easily operated features, this application serves as a valuable reference tool for your chemistry class.

Plankton isn't just a tiny cartoon character, it's also a very important food source for animals around the world. Budding scientists discuss the types and functions of plankton, including where they are found, how they are caught, and...

Individuals analyze tree rings to determine the health of an ecosystem. They then look at otoliths of fish, hard calcium carbonate structures located behind the brain, in the same manner. 

Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...

Investigate the properties of rocks and minerals through a rockin' hands-on activity. Learners test rocks for various properties and, using a guide, attempt to identify different samples. They use various properties including hardness,...

Archaeologist David Hurst Thomas details his search for a lost Spanish Mission on St. Catherines Island, Georgia. A great way to introduce youngsters to the life of and the tools used by archaeologists.

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. 

Observation of sister chromatids is possible as students culture and stain mammal tissue cells.  

Learners will love a weeks worth of bone study. They use bones and characteristics of bones to explore the evolution of hominoids. Bones are compared, categorized, and considered. A great way to bring physical anthropology and material...

Learners build plankton models and compete to see which sinks most slowly. They write, or orally present ,the adaptations they incorporated to slow the sinking rate of their organisms. Race results can be grounds for some prizes!

Learners conduct a simulation to explore how scientists estimate the size of animal populations. They analyze a random sample and then extrapolate those results to a larger population. Additionally, they will apply the principals of...

Students take on the role of epidemiologists. They investigate an "outbreak" in serious birth defects that occur in infants born to teenage girls. students discover a link between the use of the acne drug called Accutane and birth defects.

Students record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights

Find an answer to the age-old debate of whether life exists on Mars. Groups determine criteria to help look for signs of life on Mars. The activity has the class simulate testing Martian soil samples for signs of life before drawing...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

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.

Help your class understand the magnitude of the distance between Earth and Mars with an activity that asks small groups to use balloons to create scale models of the Earth, Moon, and Mars. Class members figure out the distances...

Investigate the life of bugs and how they interact with the environment in this integrated science and language arts lesson. Young scientists construct mini environments in cages in order to make observations. This data forms the basis...

Students identify and experiment with dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible climatic conditions might affect tree growth in their...

Students participate in classroom experiment to gain better understanding of type of environment brine shrimp can best survive. Students then explore effects of common saltwater pollutants on survival of animals in sea.

Young scholars are introduced to 6 different lesson that deal with biology they include: The Good and Bad of Bacteria, An Introduction to Microbes, Microbes That Are Your Buddies, Bacteria and Water Purification, Microbes are Everywhere,...
