High schoolers predict the required stress to break a candy bar. They examine how a various substances break and infer a cause for the type of break. Students relate the candy bar experiment to the importance of nanotech laboratory work...

Pretty purple slides present a plethora of jargon related to genetic engineering. Most of them have one term across the top and a brief explanation of that term below. They are arranged in alphabetical order, which may not be the most...

In this periodic table I quiz, students select the best answer to the given questions. Students apply their knowledge of the periodic table and the arrangement to correctly answer the questions presented.

Ninth graders explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They demonstrate that isotopes of an element have different masses. Students demonstrate that the rates of...

In this gases worksheet, students use the concepts of Graham's Law of diffusion to determine the velocity of gases and molecules. They describe kinetic energy and how it relates to the mass and velocity of objects.

Young scholars examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

Students identify how to relate the position of an element in the periodic table to its atomic number and atomic mass. They identify how to use the periodic table to identify metals, semimetals, nonmetals, and halogens, and also,...

In this periodic table worksheet, students complete a chart with the appropriate element symbol, the atomic mass and the atomic number. They classify elements by their groups and as metals, nonmetals or semi-metals. They also answer two...

In this chemistry worksheet, students determine the number of water molecules is a given volume of water. Students determine the empirical formula for given compounds from the percentage mass of elements. This worksheet has 20 problems...

In this literacy worksheet, students look for the words in the puzzle that are related to the theme of the word search. Spelling skills are worked on.

Ninth graders explore the abstract idea of the atom and explain the differences and similarities between solids, liquids, and gases. They understand the molecular differences between solids, liquids, and gases.

Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

In this chemistry worksheet, students examine the concepts of mole and molarity in order to apply in the laboratory setting. The sheet includes in depth background information.

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Learners explore the strength of intermolecular attractions. They make slime and compare the difference in the physical properties of sheet and powdered polyvinyl alcohol with polyvinyl acetate.

Using a dry cleaner bag and a blow dryer, create a hot air balloon! The materials list suggests obtaining one dry cleaner bag per student, but since this is probably inconvenient, consider doing this as a demonstration during a activity...

Hopefully by the time high schoolers are enrolled in your chemistry class, they are skilled with unit conversion. It does not hurt, however, to take an hour early in the school year to review this vital skill. This plan simply provides a...

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

Students analyze data taken from proteomic experiments. In this biology lesson plan, students explain the importance of bioinformatics tools in the study of proteins. They evaluate scientific results using math and computer software.

Students analyze gas chromatograms and suggest various applications for gas chromatography.

Students participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.

Students discuss the relationships between dissolved oxygen in a stream, stream temperature, organic waste loads, and stream conditions by studying and using a model of dissolved oxygen in the stream.

Twelfth graders simulate a DNA fragment running through a gel electrophoresis in a class activity. Students work in teams as a DNA sample with each person on the team representing a fragment that moves through the gel at a specific speed.
