Students examine the major events that have taken place in the Earth's development.  In this Earth lesson students view a video and put major events in chronological order. 

Why did the mushroom go to the party? Because he was a fun guy! Biology learners study fungi while completing this learning exercise. Structure is compared to that of other life forms. The life cycle is displayed with colorful diagrams...

Students investigate the importance of sexual reproduction in evolution. In this sexual reproduction lesson plan, students simulate species with two traits: eye and skin color. They determine what characteristics are beneficial for the...

Pupils do an experiment using a microscope. In this lesson plan, about cells, students examine different slides using a microscope. Pupils look at an onion skin, cheek cells, and potato cells. In each of these, students find cell walls,...

Find out just how enticing learning about neurons can be by creating models with sugar cookies, icing, and candy. With great background information for you and an easy procedure for the kids, studying cells has never been more fun or...

Classify living things with a set of worksheets that has pupils sorting and indentifying living and non-living things. Learners use the worksheets as a basis for finding their answers. 

A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

In this bacteria worksheet, students fill in the blanks with the correct word. Students then label the structures found on a bacterium.

In this DNA instructional activity, 9th graders read a brief excerpt pertaining to the genetic code and identify how proteins know which cell to create. Then they use the genetic code dictionary to draw a diagram showing the codons for...

Students use various snacks to make large models of human cells. Items such as gumballs, gummy worms, and jelly beans represent the nucleus, golgi bodies, and mitochondria. As each piece of candy is added, the teacher explains what it...

The many slides and images in this PowerPoint are clear and relevant to the detailed content covering the details of DNA structure, replication, cell differentiation, and mutation on an advanced level. The slideshow summarizes all of the...

Young scholars 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.

Watson and Crick built the first model of DNA in the 1950s, and our understanding of DNA since then continues to grow exponentially. Scholars learn about protein synthesis by observing a presentation and completing a worksheet. Both walk...

The ciculatory system is introduced here by means of clear, labelled diagrams and charts with details. After learning the basics of the heart strucure, a sequence of slides help show the flow the blood as the heart muscle contracts. A...

High schoolers plot particle sizes of common airborne materials on a log scale. They read an article on particle size and its relationship to the ability to pass through the lungs, into the bloodstream, and eventually into the cells...

Electrons flow from negative to positive, but the general consensus is that current flows from positive to negative. Scholars explore current through construction of circuits in both series and parallel. The focus is on voltage,...

In this matching worksheet, students match fifteen words to their definition. They identify words dealing life science such as cell, cell membrane, producer, and antibodies.

Seventh graders describe the basic structure of the DNA molecule. They identify what an inherited trait is and how it can be determined by one or more genes. Finally, 7th graders identify that plant and animal cells contain several...

In this biology worksheet, 9th graders identify and locate various vocabulary terms found in the study of living things. There are 31 biology terms located in the word search.

In this protist instructional activity, students complete a crossword puzzle with 34 questions about the behaviour and different types of protists.

Students model traits on genes using colored paper and tongue depressors to represent chromosomes. In this heredity lesson plan, students use their "chromosome sticks" to understand chromosome pairs, genes, dominant traits, recessive...

In this biology worksheet, students identify and locate various vocabulary terms related to the process of mitosis. There are 19 biology terms located in the word search.

In this DNA worksheet, students read information about DNA and messenger RNA. Then students complete 16 short answer questions and color 2 images.

Explore the concept of scientific classification and the similarities and differences between plant and animal species. Your class will participate in hands-on activities by investigating dichotomous keys and classifying their shoes. To...
