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...

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 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...

Explore the concept of evolution and cell biology; your class can work in groups to use the internet to view websites on evolution, take a quiz, and complete a lab activity.

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...

Sometimes conservationists use specific plants to prevent erosion or fight invasive species. A 50-slide presentation covers both nonvascular and vascular plants. It discusses the plants, their stages and life cycles, reproduction, uses,...

The general characteristics that affect classification of fungi and other organisms in the domain Eukarya are detailed for the students on 12 attractive slides.  Teachers can access individual slides to cover life cycles or...

Get up close and personal with DNA! A two-part hands-on activity has learners extract DNA from a small organism and then their own cheek cells. Scholars then explore DNA replication using questions to guide their analyses.

Here is a lab activity adequate for use with any full lesson on environmental factors that shape animal adaptations or marine animal characteristics. Pupils will discuss the role plankton plays in the environment and filter-feeding...

It's hard to imagine that anything was missed on this five-page list of science roots, prefixes, and suffixes! Listed in alphabetical order, all are included in a single, two-column list. This may be especially useful for advanced...

Seventh graders view lab stations with Xenopus at different stages of development. They identify the life stage of the sample, as well as the previous and next stages. Students must explain their reason for selecting the specific stage.

Cell phones are likely made of gold—at least part of them! An interesting lesson explains the conventional and not-so-conventional uses of the popular element gold. From the Inca empire to modern-day technology, learners discover gold...

The general characteristics that affect the classification of fungi and other organisms in the domain Eukarya are detailed on 12 attractive slides. Teachers can access individual slides to cover life cycles or diversity, or can use the...
