Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.

Students research the development and implementation of a research vessel/vehicle used for deep ocean exploration. In this oceanography lesson, students calculate the density of objects by determining the mass and volume.

Students participate in a demonstration to test the different densities of plastics, and suggest a method that plastic waste can be separated and collected.

Twelfth graders work in teams to design a method of recycled plastics purification by flotation. They base their design on the concept that different kinds of plastics have different densities and keep overall costs and purification time...

Pupils determine how to use a quarter meter quadrant to find population density, relative density, frequency and how to calculate a diversity index while participating in a virtual field trip. They study how to establish a Correlation of...

Students explore online tutorial on polymers. In this chemistry activity, they create two polymers in the lab and compare their properties. They write a sales letter about their new and improved polymer product.

Students discover how and why the settling rate of particles differs with the size of the particles. Using different soil samples, they calculate the amount of time it takes for a sample to settle in water for up to forty minutes. They...

Students explain how wetlands minimize the impact of hurricanes. In this earth science lesson, students investigate how different materials affect the steam plume path. They complete their worksheet after the lab.

Scholars generate and collect pure oxygen through a decomposition reaction of hydrogen peroxide in the fourth lesson of an 11-part series. Then, they complete six investigations into the properties of oxygen.   

Students collect chemical, physical, and biological data from a local lake throughout the year. In addition, students discuss the design of an experimental structure for water collection at several specific depths as well as assess the...

Students investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Students perform a...

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly instructional activity, learners use scientific...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

For this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

Young scholars are introduced to the forces that are responsible for generating waves in the ocean and how these forcesf differ from those that cause currents. They are able to explain how water molecules in a wave do not move in the...

Ride the wave to an understanding of refraction! The first in a series of two inquiry-based lessons challenges learners to create transverse waves with two different types of springs. As their wave hits an object, they observe the change...

Students investigate the scientific concept of why some objects float when put in a liquid solution. They apply the laws of motion and force while conducting classroom activities. Students also take notes and answer target questions to...

Sixth graders answer questions about "From a Railway Carriage." They discuss different poetical forms. They work together to write a poem about travel.

Demonstrate the movement of lithospheric plates due to convection in Earth's mantle. Learners then model the movements that occur along plate boundaries using colored clay. 

Students investigate the carbon dioxide content of different sodas. In this chemistry instructional activity, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

Students differentiate between the weights of an object on different planets. In this geometry lesson, students investigate different weights and graph their results as it relates to the different planets. They appreciate the design of...

Students examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.
