How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...

Balloons will go where you want them to. Young pilots first add paper clips to a balloon to make it neutrally buoyant. They then use cardboard to steer the balloon in different directions, taking air pressure into account.

Combat ocean acidification with bubbles. Young engineers create a system that reduces the acidity of water. Dry ice in water helps simulate ocean acidity, and blowing bubbles into the water results in a gas exchange that neutralizes the...

Ready to learn about machine learning? Pupils explore neutral networks and machine learning by analyzing the logic used in a single perceptron model. They consider its weaknesses and then use a multi-layer perceptron model to run...

A male nurse? A female welder? Unequal pay? The "Glass Ceiling?" A 22-page Gender Equity Activity Book asks participants to examine the effects of gender role stereotyping on career choices. Class members also update job titles...

High school juniors learn how to construct a strong argument by crafting a claim and using neutral language backed by evidence from reliable sources. To do so, they learn to evaluate sources and evidence to support claims. They then...

While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...

Amaze your scholars with an activity that uses a Cartesian diver to demonstrate Pascal's Law, Archimedes' Principle, and the Ideal Gas Law. Groups then repeat the process and make their own diver move up and down in a bottle.

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

What did you have for dinner last night? Many scholars ask that question without considering the history behind the foods they eat. Using a simulation, scholars investigate how the foods they eat are the product of the Columbian...

Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...

How do scientists determine the best method for removing pollutants from our water sources? Environmental scholars experiment with pollution clean-up options to discover which are the most cost-effective, fastest, and most thorough....

Will your next buoyancy lab rise to the occasion? Make a splash with action figure divers! Teams of young physicists explore the relationship between mass and buoyancy by adding weights or balloons to achieve a diver that neither sinks...

Groups create a set for a play or story they select, build a model, and share their stage with the class. The team explains the rationale for their choices and the mood they feel their staging creates.

Slide paper over a plastic straws to generate static electricity, and then stick that straw to glass, a wall, or even your own hands! This is a science activity that students can use to show parents what they learn in school whenever...

Explore self and social construction with a hands-on art project. After studying and discussing bullying and other social experiences, individuals create three paper dolls that represent specific social constructions. Included here is a...

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

Free Trade and Sailor's Rights! Pupils dive into America's first declared war, the War of 1812. They analyze the presidencies of Jefferson and Madison through diary entries and historical reasoning. To conclude the lesson, they use their...

What is the difference between a Cold War and a Hot War? Scholars research the beginning of the Cold War. They analyze diary entries as well as excerpts from various events during the 45-year standoff. To finish, they prepare final...

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

Get up close and personal with DNA! A two-part hands-on activity has learners extract DNA from a small organism and then their own cheek cells. Scholars then explore DNA replication using questions to guide their analyses.

How does a change in pH affect the ocean ecosystem? Scholars explore the idea by making an acid-base indicator in part seven of the 10-installment Discover Your Changing World series. First, they explore impacts of carbon dioxide in...

What does the author believe about his topic? Why did he write in the first place? Challenge your class to figure out the answers to these questions as they read through informational texts. The resource provides a breakdown of the...
