Students explore how DNA fits into chromosomes and how chromosomes relate to the human body. They learn about DNA replication and protein synthesis and model these two processes in Web activities.

Students examine the X and Y chromosomes. In this research lesson, students use the 5E lesson model as they read articles about human chromosomes then discuss their findings and opinions.

Students define the key terms that are the structure and function of DNA. In this genetics instructional activity students complete a lab activity in which they construct a model DNA structure.

In this chemical formulas learning exercise, students practice naming molecular compounds by their formulas and determine if a gas is a compound or an element. This learning exercise has 13 fill in the blank questions.

Add a little heat to your science lesson. Young experimenters work to understand the chemical reaction taking place when a candle burns. They experiment with both oxygen and carbon dioxide to make conclusions about the reaction.

In this bonding instructional activity, students fill in 8 blanks with the appropriate terms about theories of bonding, they determine if 6 statements are true or false, they match 5 terms with their meanings and they solve 1 problem...

Students explore the basic process of natural selection and how people can manipulate that process today. The consequences of natural selection on daily life and the implications of evolutionary biology in basic and applied science is...

High schoolers explore the structure of DNA and the process of DNA replication, describe the process of protein synthesis, recognize the importance of proteins in the human body, and look at how mutations affect protein synthesis.

In this creating bonds worksheet, students create 2-D and 3-D models of the molecular formula provided. Students complete a chart of information about the molecular formula given.

Learners 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.

A nicely formatted set of slides that logically follow and define the structure and function of the genes in Bacteria. The repressor proteins and other gene regulators are listed and diagrams support the explanations of their function on...

Pupils 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, alkaline...

What has a thermometer earned that your pupils haven't? A degree! After reviewing the previous lessons about molecules and degrees, scholars observe how thermometers work before building their own. The module includes a activity sheet.

How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer. 

A fuel cell is where the jailer keeps gas guzzlers. Scholars review chemical reactions, chemical bonds, and chemical structure in order to apply these concepts. Participants construct fuel cell kits, using electrolysis to run the car and...

Of quartz I love geology! The chapter offers five activities at three different levels. It features hands-on activities that cover crystal shapes, cleavage and fracture, hardness scale, specific gravity, and mineral...

How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of...

Students perform an experiment involving reverse transcriptase-polymerized chain reaction HIV replication to better examine the biotechnology used by scientists in pharmaceutical research of infections diseases like HIV. Students examine...

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a lesson in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the...

Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson. In conjunction with the research students make inquiry of the...

Finally, a chance for the class to play with their food! Allow pupils to simulate stomach acid with common foods, and introduce specific macromolecules into the mixture to explore characteristics of carbohydrates, lipids,...

Lead your high school class on an exploration inside the cell. Individuals investigate the relationships between cells structure and function given their relative locations on the cell membrane. They explore the concept of homeostasis...

Scholars use sorting cards to try to define a pure substance versus a mixture. Risk becomes reward as they observe the differences and create a flowchart sorting matter into mixtures and pure substances (elements and compounds).

Cells of different organs have unique cell functions. Learn how cell functions vary depending on their roles in the body using an inquiry-based activity. Scholars analyze the cell structure to make comparisons to its functions, allowing...
