In this beef activity, students participate in a variety of activities including completing a digestion dilemma, identifying best meat cuts and selecting a service project to complete.

Information about digestion of various food components is given in this PowerPoint. The diets of herbivores and carnivores are compared, and there are many diagrams giving details of their digestive system specializations. The...

Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.

Introducing enzymes and the controlling factors of a reaction this slideshow displays the typical rate of reaction graph and labels the main sections. The summaries of ways to measure reaction rates are valuable and the examples of...

Explore human anatomy and physiology using models. Scholars study systems of the human body and design a display for a museum exhibit. To complete the activity, individuals create analogous models of their chosen human body systems.

Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

In this digestive system worksheet, 3rd graders use a word bank given to label parts of the digestive system. An answer key and website reference for additional resources are given.

Pigs and humans have the same metabolism level and similar organs and systems, which is why they are often used in scientific laboratories. This worthy virtual dissection of a fetal pig divides into eight chapters: anatomical references,...

Seventh graders investigate the structure and function of body systems and their inter-relationships. They draw and label the major body systems, observe demonstrations of various body systems, define key vocabulary terms, and compare...

Students complete a digestion experiment using sugar, iodine, corn starch, and sugar test paper to test for starch and sugar in the body. In this digestion lesson plan, students learn how the body breaks down different ingredients.

Seventh graders Name and locate the major internal organs of the human body and the frog. Students virtually dissect a frog and compare organs to the human organs. Students draw illustrations of their learnings.

Fifth graders compare physical and chemical changes. They perform a simulation experiment/activity that replicates what happens in the stomach as food is digested by stomach acids.

Students examine and compare traits of humans and crocodiles.  In this crocodile lesson students use a ratio to estimate the height of a person and compare that to a crocodile. 

Students demonstrate the path of food in the body. In this biology lesson plan, students conduct an experiment to determine how large the the digestive system is. They name the different organs involved in the digestive process.

In this human body activity, students will review the characteristics of the body systems: skeletal, circulatory, muscular, digestive, urinary, endocrine, reproductive, lymphatic, and respiratory systems. This activity has 12 fill in the...

In this human organ systems worksheet, students write the organ system that is described in the first 5 sentences. Students match the body parts to the organ system and write them in the chart.

Students explore various parts of the heart and blood vessels . They begin with an overview of the components of the cardiovascular system. They see a cross section of an artery and watch how a blood clot develops.

The human body contains more than 200 types of cells, and plants contain many other unique types of cells. While a huge variety of cells exist, they appear to have very similar structures. A detailed presentation describes the structure...

Whether you need a new textbook for your health class, or a few exercises and passages for your lesson on nutrition, you'll find what you need with a thorough nutritional science resource. With 15 chapters that cover elements of...

Examine the nature of landfills through experimentation. Scholars build miniature landfills and monitor changes over a six-week period. Observations allow individuals to draw conclusions about the different types of trash and their...

What do Mike Tyson, Ellen DeGeneres, and Paul McCartney have in common? They're all famous vegetarians. Using the resource, scholars learn about the pros and cons of eating a vegetarian diet. They read a fascinating history of...

In this chemical reactions worksheet, students read about the differences between physical and chemical changes in substances. Then students identify situations as either an example of physical or chemical change. Students learn how to...
