Students explore what the stoma does for a plant.  In this botany lesson students complete a stomatal peel experiment and measure its densities.

Students study the process of stratification and seed dormancy.  In this germination lesson students prepare a medium in which to grow  seeds.

Students explore the uses of sequence alignment.  In this DNA lesson plan students complete several experiments on sequencing and algorithms. 

Students examine what amylase is and its history.  For this digestive lesson students study the effect amylase has on starch and how temperature affects the rate of activity.

Students examine antigens including ones found in humans.  For this immune lesson students complete several experiments in relation to antigens and antibodies.

Students explore genetics, chromosomes and DNA.  In this genetics lesson students design a chromosome and identify a family tree through genetics. 

Students explore the basics of DNA and its history.  In this DNA lesson students extract DNA from fruits and understand how it is used in forensics.

Students explore the history, inheritance and mutations of genetics.  In this genetic lesson plan students complete experiments on DNA sequences.

Students explore the different types of balloons.  In this materials lesson students can complete several experiments including building their own hot air balloons, making balloon animals and experimenting with static...

Students build their own boomerang. In this physics lesson, students trace the origin of this equipment. They practice throwing and catching them.

Students examine how wind tunnels are used for research and development.  For this aerodynamics lesson students are given instructions on how to develop different types of wind tunnel.

Students explore what black holes are and how gravity is associated with them.  In this space lesson students are given enough information to imagine a journey to a black hole. 

Students study cosmic rays and the energy behind them.  In this atmospheric lesson students complete a cosmic ray telescope project. 

Students investigate the different types of sundials and their history.  In this shadows and time of day lesson students build their own sundials. 

High schoolers separate food coloring using liquid chromatography. In this chemistry instructional activity, students explain the effects of different solvents on the rate of separation.

Students make glurch using materials provided. In this chemistry lesson plan, students identify the physical properties of glurch. They compare its properties to commercially prepared ones.

Students develop a method to separate different types of mixtures. In this chemistry lesson plan, students model the steps in the scientific method. They perform the experiment and analyze data.

Students explore oxygen and its physical and chemical propeties.  In this investigative lesson students complete several experiments using oxygen.

Students perform a series of tests on water-based paints. In this chemistry lesson, students identify their different functions. They calculate paint density and fractional concentrations.

Students create a polymer ball in the lab. In this chemistry lesson, students identify the different properties of the polymer they created. They explain what type of chemical reaction took place.

Learners explain the process of polymerization. In this chemistry lesson plan, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.

Students examine the mineral pyrite and discover the differences between it and gold.  In this mineral lesson students identify minerals using their common properties.

Students observe the rusting process in the lab. In this chemistry lesson, students rank metals according to their conductivity. They give real world applications of this activity.

Students research the damage to the environment by certain plant species. They create an experimental design which they test how these species take over certain habitats. They share their information with the class.
