A three-page quiz assessing budding biologists' understanding of classification. Middle-level learners may need a little additional time on this, but should be able to handle the concepts with ease.

Tic-Tac-Toe is a game most students will be familiar with. This fun activity prompts students to answer questions about cells organelles in order to place a mark on the grid. There are some non-essential humorous sound effects and...

Multiple choice, fill-in-the-blank, short answer, and matching questions are all here in a multi-page worksheet or quiz. While the formatting leaves a little to be desired, it would take just a few minutes to change the handout into a...

With this collection of slides, future biologists get to view photographs of protozoans from different phyla. Interspersed with the photos are bullet-style notes listing characteristics of each group. Unfortunately, most of the pictures...

Eighth graders use a large Punnett Square and infer how genes determine blood types.  In this blood type lesson students predict blood types and demonstrate how Punnett Squares are related to genes and chromosomes. 

In this DNA instructional activity, students identify the different parts of the DNA and color them. They complete 16 short answer and fill in the blank questions on DNA.

Did you know that meat tenderizers contain DNA cutting enzimes? Did you know that you can isolate your own DNA? Or the DNA of fruit? Explore with your learners the DNA world with a series of experiments using readily available materials...

Young scholars investigate the process of genetic engineering. In this genetic engineering lesson plan, students use paper models of DNA and plasmid bacterium to investigate the process of replicating DNA, splicing genes from DNA, and...

Eighth graders are able to define meiosis. They are able to compare and contrast meiosis and mitosis. Students are able to state the phases of meiosis. They complete a K-W-L chart on meiosis and mitosis. Students talk about meiosis...

Students research genetic adaptations. In this chromosome lesson, students investigate dominant and recessive genes using spiders indigenous to Hawaii. Students create Punnett squares to determine the probability of passing specific...

For this sponges worksheet, students read the information about sponges. Students answer the provided questions about the reading passage. Students color the illustration at the bottom of the page.

In this Euglena and Spirogyra worksheet, high schoolers read about these two Protozoans and they answer fourteen questions about their specified structures and functions. They color a diagram of Euglena and Spirogyra and label their parts.

In this life cycle workbook, 5th graders examine plant and animal cells, classification of organisms, human biology, photosynthesis, and natural environments. 21 different activities make up the Life Cycle Workbook.

In this science worksheet, students complete five sentences about genetics by choosing the correct word from a list. For example, "Inside each cell is one..."

Eighth graders discuss and write about what led up to the discovery of the atom. Students label proton, nucleus, electron, and neutron in their notes. Students take notes on electron shells and how different atoms have different...

Students examine the difference between mitosis and meiosis, and describe the steps involved in meiosis and the significance of each step. They create a diploid nucleus containing two pairs of chromosomes using clay.

This PowerPoint includes a game with ocean graphics in which two teams answer increasingly difficult questions about animals. Topics covered include plant and animal cells, animal adaptation, and similarities and differences between...

In this nervous system worksheet, students are given seventeen clues about structures of the nervous system and they put their answers in a crossword puzzle.

In this DNA worksheet, students will compare the chemical differences between DNA and RNA. Students will review what makes up the genetic code and the steps of transcription from DNA to mRNA to proteins. This worksheet has 26 fill in the...

In this protein synthesis worksheet, learners complete 17 questions about making proteins through the process of transcription and translation. They use a sample of DNA to make a protein using a given tRNA dictionary.

Young scholars examine the importance of proteins including their function and structure.  In this protein lesson students play a game to help them better understand proteins.

Sixth graders examine how plants collect water and breathe. In groups, they participate in a variety of activities in which they discover how plants operate in terrariums. To end the lesson, they discuss why plants are important to the...

Students isolate DNA from different food sources. In this biology instructional activity, students research DNA extraction. They analyze DNA stands collected from the lab, and compare the differences between each.
