It's the stairway to learning! Scholars research all aspects of building a staircase. Using information from building codes, they write and graph a system of inequalities to analyze the constraints. The completed project is a scale model...

The fastest growing volcano in recorded history grew more than 150 meters in less than a week and to more than 424 meters in less than a decade. How do we safely monitor active volcanoes? Young scientists design an...

One of the most recognizable commercial melodies was written in 1977, and led to gastronomical relief around the world. Scholars use Alka Seltzer tablets to measure reactants and calculate the chemical equation for the reaction of NaHCO3...

In the summer of 1815, snow fell every month in New England. Was this related to the volcanic eruption of Tambora in Indonesia earlier in the year? Young scientists design their own experiments to research the long-term effect a volcanic...

Host an exciting lab in which learners burn fruit rinds to better understand hydrocarbons. A reading passage and analysis questions wrap up the lesson. 

High schoolers test wood splints that have been soaked in mystery solutions to identify the different colors it produces when lit. The lesson concludes with a reading passage and analysis questions.

Did you know you can melt the metal gallium with just the heat of your hand? Pupils observe and test materials in order to classify them as metal or non-metal. A reading passage and analysis questions wrap up the lesson. 

Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

Never trust an atom; they make up everything! Young chemists make modeling dough and add another ingredient to change the properties. Scholars then compare the properties of emulsion to composite materials. A reading passage and analysis...

Young scientists use electrolysis to separate water into its elements before experimenting with fire to learn about their properties. A helpful resource provides a reading passage and analysis questions. 

Take a deep dive into Oregon's ecosystems, plants, and changes from the past to the future. Many hands-on activities in an environmental science unit delight scholars, including creating a field guide for a local park. The in-depth study...

A chemistry instructional activity presents 14 chemical reactions for scholars to observe, write the equation, and balance the equations. Additionally, it provides ways to extend the activity as it relates to catalysts.

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

Young scientists play tag as they act out the food pyramid in the ocean ecosystem. Energy circles pass from the smaller prey to the predators and at the end of the activity, a data chart and analysis questions allow pupils to apply their...

What did one titration say to the other titration? We should meet at the end point! Young chemists perform four experiments: dilute solution, neutralization, titration, and figuring pH/pOH. 

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

Magnets don't grow in fields, but magnetic fields are important to understand. The lesson covers the effect electricity has on magnetic fields. Scholars use a compass, magnets, and electrical wire to test magnetic fields and energy...

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this instructional activity. The material includes clear instructions for each...

Young scientists build their own electromagnet and test it by picking up paperclips. Analysis questions evaluate knowledge at the end of the activity. 

How can a hand puppet's shadow look like a dog? The lesson explains the science behind shadows, combining paint colors and the colors used in old televisions. Scholars use white, red, blue, and green lights to experiment with colors...

The lesson allows young scientists to use lasers and mirrors to study reflected light. A reading passage and homework question assess learning, while additional material introduces extension activities. 

How many of your pupils play an instrument? A musical science lesson will help all of them understand how string instruments work. Young scientists construct a string-and-pulley system to test frequency and pitch. The lesson...

Covering both permeability and porosity, scholars perform a hands-on experiment testing various soil types. The material includes a pre-instructional activity worksheet to help focus pupils on the task at hand. 

My name is Bond, Hydrogen Bond. Written for distance scholars working on chemistry at the high school level, the lesson includes eight weeks worth of material divided into six parts: substances you use, mixing it up, your skin, what's...
