Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

The first in a six-lesson mini unit, all using M&Ms® candies, this physical science activity gets kids to observe a single piece and discover what happens when it is placed in a plate of water. The activity can be used to...

Four different-shaped and dyed pasta types represent four different alleles. Following a guide sheet, young geneticists practice randomly selecting alleles and discover the traits of the resulting offspring. This is a fun and solid...

Give pupils a magnifier, a mirror, and a flashlight so that they can examine their own pupils. As they shine a light on their eyes, the light is shone on how this structure dilates and contracts to control how much is allowed into the...

Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...

As Mia and RJ discuss measurement, your class is introduced to the customary and metric systems for measuring mass, capacity, weight, and length. Temperature scales are also introduced. This resource can help set the foundation for later...

To illuminate how afterimage occurs, create a star, square, or other geometric-shaped light for learners to look at for 30 seconds. Then, have them explain what they see as they shift their focus to a blank wall. A full explanation of...

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

Here is a fun little exploration of the potential energy potential of falling water. Learners drop water from various heights using a straw, and they analyze the diameter of the splash. Pair this with two more activities of the same...

Explore the world's water without leaving the classroom! For this second of three uncomplicated but wonderful activities, physical science learners feel the pressure of water. They discover that the deeper the water, the stronger the...

Using popsicle sticks and glue, groups must work together to design and build a bridge that can support weight and is aesthetically pleasing. The activity begins by learners reading about different features of bridge architecture,...

Working under specific constraints and with designated criteria, groups work together to create a product using an assembly line process. In addition, they work through the entire engineering design process with an excellent graphic to...

Sure, you may be able to build a better mousetrap, but what about a gum dispenser? In a fun engineering challenge, teams must design and build a working interactive gumball machine with specific constraints and criteria.

To prepare for the activity, STEM classes read about nanotechnology and the amazing properties of graphene. They collect a graphene sample from pencils, and then connect them into simple circuits to determine whether it makes a better...

Fascinating reading about nanotechnology, nanoscale properties, and liquid crystals precedes a fun activity for young engineers. They measure their hands in nanometers, research, and then investigate how heat effects a sheet containing...

A comprehensive resource gets fourth grade physical scientists making observations about the period of a pendulum and then applying knowledge to a playground swing. Through seven different stations, they will record observations and...

Sometimes engineering problems that seem easy prove to be more challenging than imagined. Present your class with the challenge to build a functional display tower to support a statue using only the supplies available in class while...

Providing clean water to a town is quite a feat... is your class up for the challenge? After a short reading about water towers, groups work together to design a working water delivery system. The water flow must be adjustable (able to...

A fun and challenging activity for nearly any age group, partners must work together to build the tallest structure possible using paper clips, straws, and pipe cleaners. In addition to being tall, the structure must also be able to...

The slope of the land is an important feature when considering the erosion that will occur. In this resource, which is part of a rain garden unit, learners calculate the slope of the proposed garden site. Even if you are not planning a...

Here is a six-minute video of a pair of electrical engineers that illustrate how to build a wind turbine. A list of materials is provided, along with general guidelines for your class. Use this to introduce turbine design to your...

Mike and Kellie, a team of electrical engineers, demonstrate how to to design a contraption that accurately drops a marble onto a target. The materials needed and general instructions are provided on the website or via a downloadable...

Upper-elementary kids examine the water usage in their own home, then use that data to solve a case in which a landlady is trying to determine how many people are living in an apartment being rented. Combine math, scientific method, and...
