Students research an event, celebration, or observance from a culture with which they are not familiar and present their information to the class in this cross-curricular look at festivals and celebrations. The lesson includes an option...

Use background information and vocabulary to familiarize your students with the concept of symbiosis and the role agriculture plays in the shared relationship. They then write the vocabulary in their lab books or journals, and read the...

High schoolers identify the parts of the human body involved in reproduction. They examine the process of fertilization and discover all species reproduce. They practice using new vocabulary as well.

Middle schoolers explore the concept of water pollution. In this environmental stewardship lesson, students discover what watersheds are and consider how to protect them.

High schoolers identify pictures of women labeling them pregnant or not pregnant. They discover what happens inside a woman when she is pregnant. They explain the relationship bettwen intercourse, fertilization and parenthood.

Students complete two labs. They observe the fertilization and development of sea urchin and zebrafish embryos. They examine the similarities and differences in the development of an invertebrate vs. a vertebrate animal.

Students solve a crime by matching a suspect's blood type to physical evidence collected at the crime scene. In this forensic science lesson, students identify the different blood types. They explain how blood tests work.

Learners observe water samples and measure the samples' water quality. Learners develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.

Students are given an introduction to the "ecosystem", what factors make up an ecosystem (biotic factors, abiotic factors, food chain, producers, consumers and decomposers) and how those factors interact.

Students explore how the environment shapes man, how man transformed his world, nd how art became part of the human process. The group is divided into clans and their migratory routes developed in the eight lessons of this unit.

Students create a model of a salt marsh to discover the impact of pollution and human activities on water-based habitats including bays and the ocean. They recognize the relationship between natural and developed areas. Students impact...

Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...

Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then...

Students study the basic processes by which cells divide and transfer their genetic information. They recognize and distinguish possible inherited traits and through the discovery method of the facts and principles of inheritance....

Students classify and record objects they find "underground." In this observation lesson, students dig into bins filled with soil and encounter various objects such as bark, twigs, etc. Students classify their findings.

Students predict the probable mode of inheritance from a pedigree diagram showing phenotypes. They study the genetic basis for Mendel's laws of segregation and independent assortment. They give a Power Point slide show demonstrating the...

Students conduct experiments on fertilized chicken embryos to determine the possible developmental effects that various recreational drugs (caffeine, alcohol, nicotine, and aspirin) might have on them.

Fifth graders use the dots to simulate water pollutants in a lake. They use cups to collect a sample of "water." Students sort the dots by color and record the number of each dot color under the correct pollutant name in the Lake Water...

Students explore ocean pollution.  In this ecology lesson, students view a video entitled This Pretty Planet and identify common biodegradable products. Students participate in activities designed to simulate the negative effects of...

Second graders grow a classroom garden that acts as a living laboratory for cross-curricular activities. In this classroom garden instructional activity, 2nd graders follow directions to build and plant a garden that is used to teach...

Fish are no different when it comes to a living being's primary objective—to reproduce. They do differ, including from fish species to fish species, in their life cycles, survival tactics and reproductive strategies. After discussion of...

Provide a meaningful context for learning about the division of fractions with this upper-elementary math lesson. Presented with a simple, real-world problem, young mathematicians work in small groups to develop visual models...

Students study how chemicals can be very dangerous when not treated with care. They watch Ammonium Nitrate power point and read about accidents involving ammonium nitrate: Halifax Explosion, Oklahoma City Bombing.

Students recognize the variety and frequency of severe weather occurrences. They research the type of severe weather that may occur in their area as well as determine the frequency of occurrence.
