High schoolers explore what factors influence the spread of infectious diseases. They explain how human manipulation of the environment affects the transmission of diseases.

Learners examine how materials oppose the flow of an electrical current.  In this resistivity lesson students complete several experiments on the differences between resistance and resistivity.

Students examine population growth and how it impacts our environment.  In this population lesson students identify the causes and consequences of overpopulation.

Learners 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 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 estimate the live mass of dinosaurs. Using dinosaur and modern animal models, students use simple displacement methods to calculate the volume of the models. They calculate the masses of each model. Students compare the...

Young scholars use a microscope and observation skills to compare and contrast several physical properties and develop a classification system.

Students examine the types of plants brought over to America from immigrants. They research how some of these types of plants cause damage and alter the landscape. They record data and share the information with the community.

Students work with data from a seismic wave model in a freely available GIS (geographic information system) program, ArcVoyager SE. Using a GIS, they examine maps and produce graphs to explore variations in seismic wave velocities at...

Ninth graders explore the concepts of motion, velocity and acceleration through graphing their own movement using LoggerPro. They become more familiar with the computer technology. Students explore graphing in real time and graph on...

After students conduct the two associated activities, Density Column Lab - Parts 1 and 2, present this lesson to provide them with an understanding of why the density column's oil, water and syrup layers do not mix and how the concepts...

For this inquiry lab activity, students will attempt to layer 6 different kinds of soda pops in a large test tube using their knowledge of density and other physical properties of liquids.

This is a guided inquiry activity in which students use simple lab procedures and discussions to develop and apply the concept of density. Students collect and graph data which they use to explore the relationship between mass and...

Because different liquids have different properties, density also differs. In this activity from the Illinois Institute of Technology, students will calculate densities of water, dish-washing detergent, cooking oil, and other liquids.

This lab experiment has students observe and compare the density of five different liquids while measuring mass and volume.

A field based lab experiment where students work in groups to come up with a collection strategy and lab analysis to test differences in soil bulk densities. Students bring soil samples back to the classroom to conduct a test that...

In this chemistry field lab, students will determine the density, pH, and water content of 4 types of soil. Students compare class data and write a lab report describing their results and then analyze their findings to report on the...

In this lab, students will use the scientific method to design an experiment that explains how/why a submarine floats and sinks.

Learners find the densities of objects based on sinking or floating in this activity that demonstrates Archimedes Principle.

In this introductory lab activity, students will collect data that will graphically illustrate the relationship between mass and volume in determining the density in chemistry. Based on density, students will seek to determine a...

In this lab activity, students are required to write a procedure to be followed in a simple lab process and record the results they get from following that procedure. They then exchange procedures with another lab group, which will have...

In this earth science lab, students will find, identify, and create a visual presentation of the rocks that are found around their school. They will determine the mass, volume, density, color, texture, and hypothesize what each rock is....

In this lab, students will demonstrate observation skills as they design an experiment to separate colors of various water-based pens in order to learn about mixtures and solutions. Students will determine a variable to test and complete...

For this biology field lab exercise, young scholars conduct a stationary population study of goldenrod galls. They examine a host of factors including goldenrod plant density, goldenrod gall density, gall height, gall mass, larval exit...
