This two-page quiz mostly covers ATP, but touches on autotrophs and heterotrophs, as well. Learners show what they know through multiple choice, fill-in-the-blank, and short-answer questions.

Students differentiate the characteristics of living and nonliving things. In this life science lesson, students compare and contrast robots and living things. Given an object, they decide whether it's is living or not and defend...

Tenth graders work in teams to order events of DNA transcription and translation protein synthesis. In the second lesson, they put the steps of mitosis and meiosis in order using a concept map poster. They use modeling clay to create...

Students explore the world of the very small using a Flash plug-in Virtual Electron Microscope. They complete and discuss an activity in which unknown samples are placed under the computer simulated microscope to determine where the...

Young scholars examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson plan students demonstrate a semi permeable membrane.

Students explore the structure and function of the cell. They begin by identifying the cell as the common unit of life in all living organisms, large and small. They examine single-celled organisms and how they carry out different life...

High schoolers examine different levels of organization in biological systems for structure and function relationships.  In this biological systems lesson, students use Internet resources to look at structure and function in the...

Students explore pond ecosystems. In this living environment lesson, students observe the local pond and identify the living things they find by drawing pictures. Students observe organisms that were found in the pond by using a...

Learners identify the different requirements for photosynthesis to take place. In this space science instructional activity, students simulate conditions in Saturn to investigate if photosynthesis is possible there. They use data and...

Learners explore the structure of a plant cell. They carefully peel a single layer of onion skin from a slice of onion and stain it with methylene blue to observe the structures inside. They use a Digiscope connected to a computer to...

In this marine science worksheet, learners complete a crossword puzzle with 32 questions on sponges and cnidarian. They identify the different characteristics of sponges and cnidarian.

Students study tissue engineering and its risks and benefits.  In this biology lesson students take a stand on a side then research and support their position. 

Students, in groups, consider a scenario in which some structure of a cell has been changed. They explore how structural change affects the function of a cell and create a visual aid to illustrate their observations.

For this cell division worksheet, students review the steps involved in a human somatic cell, from interphase to mitosis, to cytokinesis. This worksheet has 21 fill in the blank statements.

Students discover how coroners use insect life cycles to estimate the time of death in cases. they describe how forensic entomologists combine environmental factors with insect life cycles to note the changes. Students examine an...

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

Young scientists demonstrate their creativity while completing several activities, to assess genetic variations and mutations. Instructors provide a list of options and scientists choose to write a comic strip, create a book,...

The various experiments and processes that were completed in the 20th century to further our understanding of DNA are summarized here. There are wonderful slides to popularize the scientists who dedicated their professional life to...

Cnidaria is a broad phylum of 11,000 different species from jellyfish to coral. Most Cnidarians are marine species with a few freshwater examples. A lesson presentation explains the important characteristics of different species of...

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

Cells divide by one of two processes, either mitosis or meiosis. Scholars sort cards into two sets, one representing each type of cell division. Then, they sequence the cards demonstrating an understanding of the movement of chromosomes.

The Hardy-Weinberg principle is the focus of this concise slideshow.  Some vocabulary definitions are given on the first 2 slides, and the rest are given over to examples of the Hardy-Weinberg theorem. Calculations of the H-W...

Research how DNA, the genetic blueprint of living organisms, plays an essential role in the continuity of life. High schoolers will summarize how their influence may very well effect the destiny of the population from one generation to...
