Some say cooking is an art—and a science! Scholars scope out the savory subject of molecular gastronomy with a series of related activities. The teacher's guide contains printable worksheets and helpful tips for implementing the lesson...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

Did you know that California produces two thirds of the fruits and nuts consumed in the United States? That it produces almost one third of the vegetables? Did you know that scientists warn that California is facing the onset of a...

This simulation begins with an exploration of water pressure and atmospheric pressure. In the flow portion, scholars reshape a pipe and see fluid dynamics at work. The water tower portion encourages pupils to determine how water...

Why does soda fizz when opened? Learners discuss the appearance of bubbles in soda bottles when opened. In groups, they design and complete an experiment comparing the amount of carbon dioxide dissolving in cold versus hot liquids.  

Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

There are five types of frost: ground frost, air frost, hoar frost, glaze, and rime. Scholars mix ice and salt in a metal container to observe frost forming on the outside of the can. Animations and videos enhance the learning. 

Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity allows...

Ionic bonds form from electrostatic energy, allowing for higher conductivity than those seen in covalent bonds. In the simulation, learners add sugar and salt to water and see the effects on concentration and conductivity of their...

How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

A water strider is a bug that taps into the attraction between the positive and negative ends of water, allowing the bug to walk on water. Learners view short videos showing polar characteristics of water. Pairs then discuss what polar...

When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...

How can everyone in the world have access to clean drinking water? Throughout the lesson, learners read about and listen to how water is filtered, what the filtration process removes, and  the best ways to filter. They explore the...

What are the issues surrounding water quality? Viewers of this short presentation gain information about the importance of clean water, the lack of fresh water, water contamination, and ways that engineers treat water. 

Pupils make observations while eating food. They act out the process of food breaking down in the body and the roles of various chemical components, such as sugar and protein. It concludes with an activity illustrating the process and a...

Every year we discover new planets including more than 1,000 in 2016 alone. Will we ever find life on another planet? The lesson includes two activities to help scholars understand this concept. First, they analyze the temperature range...

We take a steady shower stream and clean drinking water for granted, but in many countries around the world, the lack of water or a clean water supply is responsible for higher sickness and death rates. Taking a closer look at the water...

Young environmentalists examine how water bottle use is polluting the waters on our earth. In groups, your students study the handout on their assigned topic and present their findings to the rest of the class. Leading up to this lesson,...

In this teacher-led demonstration, your young environmentalists will observe and record how different types of water pollutants look when they are combined. From here, individuals will develop a hypothesis on how the water can be...

As a follow-up from the previous lesson, young environmentalists discuss the benefits of water filtration and whether or not it's the best option. Other alternatives including air stripping, bioremediation, and phytoremediation are...

Using the polluted water that was made in the prior lesson, your young environmentalists will mix pollutants together in an experiment. Then, they will design a water filter that will clean the polluted water to use in the next lesson....

Your students will become aware of and be able to list the major types and sources of water pollution. Being able to recognize that the household, agriculture, and industry sectors of society contribute to water pollution, is the main...
