"Clean the data!" "I did not know it was dirty." Introduce your class to the process of cleaning data so that it can analyze it. Groups work through a guide that demonstrates the common ways to filter and sort data. Pairs then...

Can your biology class crack the Case of the Crown Jewels? Junior forensics experts try their hands at DNA restriction analysis in an exciting lab activity. The lesson introduces the concept of restriction analysis, teaches pipetting and...

Explore the power of mathematics through this two-week statistics unit. Pupils learn about several climate-related issues and complete surveys that communicate their perceptions. They graph both univariate and bivariate data and use...

Let the computer summarize all that data. Pairs work together to learn how to create pivot tables by following directions in the online module. They then utilize the data collected from the beginning of the unit to create their own...

Mass and density are difficult topics for kids to understand, and even more difficult when you have visual impairments or blindness. Learners will make boxes and fill them with cotton, sand, or crushed paper. They will feel the density...

How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third instructional activity of the series, learners conduct an experiment, demonstrating...

Although the methods are all scientific, forensic science was started by police officers rather than scientists, who relied on observation and common sense. Young detectives use many tools to solve crimes around the school in a...

What is the difference between weather and climate? This is the focus question of a lesson that takes a deeper look at how weather data helps determine climate in a region. Using weather and climate cards, students decide...

Columns have been used throughout the world because they are good load-bearing structures. Learners with visual impairments conduct an experiment to work through the design process as well as to understand this engineering phenomenon....

STEM scholars investigate sound attenuation by conducting an experiment in which they compare the farthest distance that they can hear a sound with and without ear protection.

You have to crack a few eggs to make a good engineer! Working in small groups, young scholars design, build, and test devices that protect an egg from breaking when dropped from a ladder.

What does the sun mean to you? Learners have many different interests that may have connections to the sun. Whether its solar radiation, solar flares, or solar storms, there are connections to daily interests that may surprise your...

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a lesson in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the...
