Everything is in the genes. Individuals observe 14 different traits of themselves. Using pipe cleaners and beads, the learners create models of a chromosome representing their traits. The class then compares and contrasts everyone's...

Students explore Ultraviolet detecting beads and conduct several investigations with them.  In this investigative lesson students participate in an experiment to see the harmful effects of UV light and discuss their findings. 

Learners explore what radioactive decay is and are able to relate it to the concept of half-life. They are given 100 green beads that represent radioactive atoms and 100 white beads that represent stable, non-radioactive daughter atoms....

Students investigate DNA strands. They study the sequence to determine if it is DNA or RNA and write the mRNA nucleotide sequence. After stringing the beads together to create the mRNA sequence they translate it into an amino acid...

Seventh graders look up pictures of viruses or pictures of models of viruses. Using pipe cleaners, beads, Styrofoam or other available materials make models of these shapes. They then observe a demonstration to show the effect of Tobacco...

In this liquids and gases worksheet, students will review the basic characteristics of water including surface tension and evaporation. This worksheet has 1 fill in the blank and 6 short answer questions.

Students experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.

Second graders examine various types of butterflies and insects around their school. They identify differences between beetles and butterflies. Students examine books about butterflies, complete symmetry drawings, and make ladybug key...

Four different-shaped and dyed pasta types represent four different alleles. Following a guide sheet, young geneticists practice randomly selecting alleles and discover the traits of the resulting offspring. This is a fun and solid...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

Third graders, in groups, make a model of a plant or animal cells and represent each of the organelles in the cell.

Students identify and define that invisible UV rays can be harmful. Then they explore the effects of UV radiation on objects that react UV rays and what products are most effective in blocking UV rays. Students also make predictions...

Students investigate patterns in solids, the structures of crystals and rocks made up of minerals. In this crystals lesson plan, students review solids, make patterns with Styrofoam balls, make crystals in the lab and observe their...

Learners review and compare plant and animal cells, and then build a model of an animal cell.

High schoolers examine the concept of radioactive dating. In this radioactive dating lesson plan, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.

Students compare and contrast plant and animal cells and then create a model of the latter. They visit Websites to view the cells and answer questions about them. In pairs, students create cell models using plastic baggies, syrup,...

Students use the internet to gather information on bluebirds. In groups, they observe and record the size, color and various sounds of the birds. They view photographs of the birds in different stages of development and discuss how...

In this properties worksheet, students review the properties of solutions, explain different physical properties, define hydrogen bonding. This worksheet has 8 problems to solve.

Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...

Students use simulated autorads to discover the principle utilized to determine paternity.

Learners make generalizations about weight and mass by engaging in two hands-on experiments. In this weight and mass lesson, students weigh both an empty beaker and beakers with various amounts of weight inside of them in order to find...
