Students examine protein synthesis and how DNA is transcribed.   In this investigative lesson students play a role in the messenger RNA when it creates nucleotides. 

Students in pairs, select and view proteins from the Protein Data Bank. After downloading the tutorial and instructions, they identify the protein's structures and primary biological functions. Then, students present their findings to...

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

The basics of mutation types and some potential effects of those are described and diagrammed here. Each detail is very clear and includes the labels and translation change exhibited. A great slideshow to expand on DNA replication issues.

After studying DNA replication and the genetics of inheritance, this slide show is useful for explaining specific mutations that can happen and result in an illness. Sickle cell anemia, and cystic fibrosis are explained on a genetic...

Covering the molecular interactions involved with DNA packing and the control of gene activity in depth, this slideshow is useful for higher-level biology students. The biochemical components of protein translation are diagrammed and...

Looking for a versatile learning exercise on organic chemistry? If so, you might consider this resource. This resource asks learners to identify organic molecules, match terms with their definitions, determine bond angles and...

Students plant seeds in order to investigate and explore the questions: "How do seed companies develop varieties of plants?" and "What is the ideal plant?" Students will study related vocabulary and sketch seeds as they emerge. Students...

Beginning biologists demonstrate their grasp on cellular respiration, photosynthesis, and energy flow though ecosystems when completing this worksheet. Fifteen multiple choice and short answer questions test their knowledge. Because of...

Students are able to give examples of local and global sources of pollution. They explain why certain forms of pollution are detrimental to the environment. Students a create a poster promoting Earth Day's message of environmentally...

Math really is just one big puzzle waiting to be solved. Show learners that math can be intriguing and provide them with visually engaging problems and puzzles. The focus is on solving simple equations and looking at expressions. 

Combat ocean acidification with bubbles. Young engineers create a system that reduces the acidity of water. Dry ice in water helps simulate ocean acidity, and blowing bubbles into the water results in a gas exchange that neutralizes the...

Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...

Students recognize how the climate of the Hudson Valley has changed since the last glaciation. They explain these changes using a reconstruction of the land use changes in the Hudson Valley composed of confetti, Ziploc bags and other...

Students recognize how the climate of the Hudson Valley has changed since the last glaciation and be able to explain these changes. They reconstruct the paleoclimate of the Hudson Valley.

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

Explore the causes of ozone depletion and the effect on plankton, algae, plants, amphibians, and humans. Learn how the Montreal Protocol has possibly helped reverse the decline of the ozone layer. Warning: photos of skin and eye...

Are you looking for a good, solid lesson on sedimentary rocks? This one, produced by the Illinois State Museum, is just such a lesson. Middle schoolers identify common rocks and minerals by analyzing sediments from local water sources....

Students view an illustration of the Hudson River watershed and identify the bodies of water shown. They discuss what happens when fresh and salt water mix. Students view a teacher demonstration of the stratification of fresh and salt...

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

Scholars learn about the carbon cycle, play a carbon cycle game, and then write a story based on their role as a carbon atom during the game. After the writings, pupils analyze the carbon cycle by leading a class discussion on the material.

If Parseltongue is a genetic trait, what is the probability a wizard will inherit the ability to speak Parseltongue? Scholars investigate magical and biological genetics with Punnett squares.

Students observe a demonstration performed by the teacher. They examine of a series of acid/base reactions and discover how various indicators work.
