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...

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...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Examine the use of photolithography in the fabrication of circuit boards and other components. An advanced activity teaches pupils a process for transferring a pattern onto a surface. Using UV light and a light reactive substance,...

Explore the consistency of the earth's layers and soil through modeling. By conducting an engaging experiment, learners develop a model for the earth's layers and a soil profile using edible materials. Each material is chosen based on...

Measure health as a triangle, with each side representing different aspects of health: physical, emotional/mental, and social. High schoolers complete a self-assessment of their health in all three areas before scoring their progress and...

Are the people on the other side of the world standing upside down? Pupils discuss the relationship between movement and position words. The unit explores the concept of reference points through animation, modeling, photography, and...

Explore the unique characteristics of polymers. A complete lesson begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...

Investigate the properties of rocks and minerals through a rockin' hands-on activity. Learners test rocks for various properties and, using a guide, attempt to identify different samples. They use various properties including hardness,...

Why do metals rust differently? Scholars experiment with metal combinations in a hands-on activity. They create unique environments with different metals and compare the rate and amount of rust for each.

Discover the connection between electric current and magnets. Scholars create electromagnets by passing a magnet through a coil. They experiment with different materials to determine the variables that affect the strength of the current.

Examine the science behind computer communication. After defining the properties of magnets, learners simulate how a computer hard drive works by sending each other binary codes using the magnets. They use these communications to...

Don't let the resource blow you away. Scholars build airboats from basic materials and collect data on how far the boats move. They refine their designs taking Newton's laws into consideration.

The radical reactions of polymers seems abstract to many pupils, but this activity turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and experimental weight...

Practice electric vocabulary using multiple methods. Learners begin by watching a video that explains vocabulary related to electric currents. They match vocabulary cards to practice and then create an electric circuit. Using the...

Who doesn't love gold and silver? Brine shrimp, that's who! Learners conduct an experimental lesson to monitor the toxicity of gold and silver nanoparticles on brine shrimp. They synthesize solutions to expose the brine shrimp to and...

There's a little bit about every aspect of weather in this trivia game. The lesson resource provides 36 questions and answers pertaining to four different topics related to weather: effects, science, technology, and statistics. Groups...

Bacteria get more resistant to antibiotics every year. Learn the reason for this pattern and how scientists are addressing the problem in a six-week unit. Learners analyze different types of bacteria and their adaptations.

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

Who likes magic shows? In the fourth of five lessons, pupils view a scientific magic trick. The ball fits through the ring easily, but then moments later, it won't pass through anymore. What changed? Can we reverse the change? Scholars...

Steam engines have been around since the late 1600s, yet most pupils don't know how they work. Using an soda can, the instructor builds a simple steam engine for scholars to observe. Through a discussion, young scientists learn about the...

Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

Can a small change in laboratory procedures save energy? Scholars test three different methods for heating water in a science lab. Then, they calculate the energy efficiency for each and compare them to determine which uses the least...
