Ethics of Dissection
There's an elephant in your classroom. That's right — a big, awkward elephant named Dissection. Sure, you'd like to talk about him ... but how? Whether you're a seasoned teacher or fresh out of student teaching, the topic of dissection...

Light but Strong: A Lesson in Engineering
Aspiring space engineers design a rocket launch platform together to explore materials. The platform needs to be lightweight so that it can be transported easily, but super strong so that it can support the weight of the rocket and its...

Welcome To Your Senses
Sound, sight, taste, touch, and smell—oh the world of senses! What do these five senses have to do with the brain? The answer: everything. Explore how the brain sends and receives messages by having the class participate in several sense...

Feel the Noise
Can you hear it now? Young scientists experiment with sound waves using metal objects and string. They strike metal objects while they hold them and as the objects hang from a string to compare the sound. They discover that sound travels...

Exploring the Colors of Mars
Minerals on Mars are not that different than those on Earth. Using mineralogy concepts and satellite images, individuals use color to highlight the different surface minerals on Mars when creating a model of the planet. They enhance...

Designing an Absorbency Test
Time to soak up some learning! A hands-on lesson teaches learners about the absorbency properties of substances. They conduct tests by dipping different materials in water to determine which hold water and then complete a handout to...

Float and Sink
We're not talking about the kitchen sink. Learners explore what types of objects sink and float in water in an inquiry-based lesson. With experimentation, they find similarities between materials that float and those that sink.

Dissolving is a Property
Believe it or not, it is possible for liquids and solids to get along! A hands-on lesson has individuals explore dissolving properties of candies in water. They complete an activity guide to record observations about different candies...

Liquids Have Properties
Liquids have many similarities, but their differences can set them apart. Using a student activity guide, learners conduct different property tests on water, oil, and syrup. They record their results and use them to rank the liquids by...

Testing Materials to Learn About Their Properties
Storing food in plastic makes more sense than storing it in paper. Young learners research the properties of these materials along with aluminum foil. They then connect the properties of the materials to their usefulness by completing a...

Classifying Objects Based on their Observable Properties
Sorting objects by properties is a lesson in justification. Learners begin by studying different types of properties of materials, including those based on appearance and texture. They examine the properties of specific items and use...

The Fate of Calcium Carbonate
Soften up an egg. Learners use vinegar to test for calcium carbonate in an egg shell and an antacid tablet and compare the reaction with vinegar to the reaction with water. In a second experiment, class members break down an egg shell...

Chromatography - Color Clues
Here's an activity that will change how one sees color. Pupils try out an experiment on chromatography where they place a drop of food coloring on a coffee filter, add several drops of water, and watch the colors spread and separate....

Chemistry Color Changers
Knowledge of acids and bases doesn't need to be a secret. Learners use red cabbage to create an indicator solution, then test how adding lemon juice (acid) and detergent (base) changes the color of the solution. They then use the concept...

All Wet
Sometimes liquids just don't get along together. A fun experiment has scholars determine whether various liquids dissolve in water. They pour isopropyl alcohol, vegetable oil, and corn syrup into cups of water to see which ones mix well...

Candy Chromatography
Don't play favorites when separating candy colors. Pupils use the process of chromatography to separate the colors of two different types of candy-coated candies. Class members compare their results to an unknown sample to determine...

Observing Water's Thin 'Skin'
Keep the tension up in the classroom. The class first observes as the teacher creates a dome of water above a glass by adding paperclips into an already full glass. Classmates then work in pairs to see how many drops of water can fit...

Balloon Astronaut
Design protection from high-speed particles. The STEM lesson plan highlights why astronauts need protection from space debris. Pupils use the design process to design, build, and test a spacesuit that will protect a balloon from a...

Investigating Physical and Chemical Changes
Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Water – Changing States (Part 2)
Here is part two of a two-part instructional activity in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one...

Introducing Physical and Chemical Changes
Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

Water—Changing States (Part 1)
Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Challenge with Solids, Liquids, and Gases
There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.

Introduction to the States of Matter
Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...
