Modeling Sizes of Planets
The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

History of Plant Classification
Bamboo, the fastest growing plant in the world, can grow up to 35 inches in one day! Pupils learn how plants historically have been classified and determine if these traits are appropriate to use in this 17th lesson of 20. They will also...
PhET
Concentration
When no more solute can be dissolved into a solvent, the solution has reached saturation. The interactive simulation allows learners to manipulate a solution in order to measure its concentration. The amount of solvent, the amount and...

Energy Changes in Chemical Reactions
Some chemical reactions produce heat, but what is really going on? Lesson focuses on the concept of energy changes, both exothermic and endothermic. Scholars perform multiple experiments, hands-on activities, and view videos of the...

What is a Chemical Reaction?
When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass concretely.

Biological Oceanographic Investigations – Keep Away
As of 2015, there are 53,481 oil wells in the Gulf of Mexico. Scholars determine how species diversity is impacted based on the ecosystem's distance from a drilling platform. It focuses on finding the mean of data sets and creating bar...

Balloons and Static Electricity
Like all electricity, static electricity flows at the speed of light, or 186,282 miles/second. The interactive simulation shows how like charges repel like charges and opposites attract. The user can choose either one or two balloons, a...

Does Temperature Affect Dissolving?
When making sweet tea, why do people dissolve the sugar in hot tea instead of cold tea? The class discusses the previous lab and builds upon it. Working in groups, they design an experiment to determine how temperature affects the...

Using Dissolving to Identify an Unknown
There is a solvent called aqua regis that can dissolve gold! After observing a solubility demonstration, groups receive four known crystals and one unknown. Based on the demo, they design an experiment to determine the identity of the...

Mapping the Ocean Floor: Bathymetry
Bathymetry is not a measure of the depths of bathtubs! Through the three lessons, scholars explore two different types of maps and how they are made. The resource focuses on topographic and bathymetric maps and teaching the techniques...

Bering Sea Fabulous Food Chain Game
In spring, the Bering Sea turns green due to phytoplankton, which live at the surface, experiencing a population explosion. Groups of scholars play a food chain game, writing down food chains as the game is played. After five to six...

Rings of Life
Individuals analyze tree rings to determine the health of an ecosystem. They then look at otoliths of fish, hard calcium carbonate structures located behind the brain, in the same manner.

Who Will Melt First?
If the Greenland ice sheet melted, sea levels would rise by about 20 ft; if the Antarctic ice sheet melted, sea levels would rise by 200 ft. Scholars explore ice melting through the analysis of different ice samples, clean and dirty ice....

Down to the Deep Virtual Lab
At a depth of 3,000 m in the ocean, the pressure is 300 times that at sea level! In the activity, individuals predict what will happen to Styrofoam cups submerged 3,000 meters into the ocean. They then convert these units to soccer...

Artificial Hearing
Your sense of hearing depends upon tiny hairs deep inside your ear and if you lose these hairs, you lose your hearing. Here, groups explore hearing through the decibel measurement of common sounds. As a class, participants discuss...

Schoolyard Biodiversity Investigation Educator Guide
In 1980, in the tropical rainforests of Panama, scientists discovered 1,200 species of beetles living in and around just 19 trees, with most of the species new to science—that's biodiversity! In the activity, learners work in teams to...
Rochester Institute of Technology
Artificial Eye
Scientists in California developed a bionic eye that allows blind people to see edges of objects in black and white and costs $145,000. In the activity, groups of scholars discuss bioengineering, focusing on the human eye. They then...

The Carbon Cycle
Scholars learn about the carbon cycle, play a carbon cycle game, and then write a story based on their role as a carbon atom during the game. After the writings, pupils analyze the carbon cycle by leading a class discussion on the material.
