This is a must-have resource with everything you'll need for studying food safety with your pupils. From handwashing scorecards and cleaning kitchen surfaces to navigating the world of microbes and food-borne illnesses,...

We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity. 

How has human activity affected Earth's watersheds? An action-packed lesson plan, part of the K20 Center, examines water's ability to go with the flow regardless of what is in its path. Scholars build model watersheds, examine time-lapse...

Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule. 

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...

While many chemicals are used in biology class, many pupils don't understand the material safety data sheets. The lesson explains each part and the importance of understanding the forms. Young scientists use safety equipment to ensure...

Learners read several websites and the story Officer Buckle and Gloria to identify bicycle safety tips. They experiment with a bike helmet and melons and create a safety poster.

A drop of dew holds a sphere shape even when sitting on a seat thanks to the surface tension of water. Learners observe the phenomena of surface tension in water. Through demonstrations, hands-on activities, and discussions they explore...

Students participate in classroom experiment to gain better understanding of type of environment brine shrimp can best survive. Students then explore effects of common saltwater pollutants on survival of animals in sea.

Sometimes when it rains, pollutants pour into sewers which overflow and contaminate the environment. The final two lessons in the Environmental Justice series looks at actions being taken to address stormwater pollution. Class members...

Students analyze the similarities and differences between tap water and bottled water. They make informed decisions about their use of each. Students are asked if they drink mostly tap water straight from the tap or water fountain. They...

Students test water for a least one chemical characteristic. They hypothesize how a storm event might change the chemical characteristics of a stream. Students collect water samples and use the chemical test to test the water.

Young scholars are taught how to format and enter data into an Excel spreadsheet. They make a graph and interpret graphed data. Students discuss possible impacts of water chestnut invasion. They graph data on water chestnut. Young...

The 2016-2017 protests over the Dakota Access Pipeline (DAPL) motivated Camille Seaman to create "We Are Still Here," a photo essay featuring portraits of contemporary Native Americans who protested the pipeline. This eight-page...

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,...

We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...

This lesson is an investigation of soil properties, particularly texture, color and space for air and water. Student inspect soil samples found in their locale, perform several tests to determine different properties, and involves a ...

How does weather play a role in the lives of land and sea creatures? Find out with a lesson focused on habitats and the ways animals from different homes are connected. Here, learners explore how the life of a jaguar and howler...

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.  

Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

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. 

Explore ocean habitats with a lesson that showcases the home of manatees and loggerhead turtles in Belize. Here, pupils compare and contrast the homes of ocean animals to those of humans, listen to an original short story about...
