When measuring the circumference of a tree, does it matter how high you place the measuring tape? Most scholars have never considered this question, but scientists know that measurement techniques must be standardized. The 13th lesson in...

Here is a collection of readings to be discussed in the science classroom. This one is in the form of a dialog between two boys in an amusement park, talking about the forces involved in a Graviton ride. Questions are listed at the...

Get kids' heads spinning by challenging them to design a top that will rotate for a minimum of 10 seconds without leaving a 30-cm circle. Groups of learners collaborate through a planning stage, testing stage, and evaluation stage. Some...

Tree rings from North America give a continuous history of El Nino intensity over the last 1,100 years. Scholars learn how scientists use tree rings to create timelines demonstrating variations in weather patterns. The cumulative...

Does having an addict in your family make it more likely to become one yourself? Explore the genetic risk factors, as well as the prominent environmental influences, for substance addiction in a lesson that encourages awareness and open...

Evidence shows the Vikings likely navigated by using a simple sundial to find their course. Videos, a short story, and discussion help bring this time period to life as they study European history with a hands-on experiment. Scholars...

Kids in grades K-2 increase their logical reasoning and visual discrimination skills by determining which things shown are alive. They use the criteria that all living things move on their own to mark each image as alive or not. 

Young scientists study light reflection and refraction as they determine the critical angle, the rainbow angle, and color separation in rainbows. Teams record the data they collect in a shared spreadsheet and discuss results with the class.

Learners use classification skills and clues to determine which flying insect is the one they need to circle. They read four clues and examine each of the five insects depicted. They then deduce which one is the mystery insect. Answers...

Students research physical science by completing worksheets. In this gravity lesson, students read assigned text regarding the rotation of Earth and the gravitational force caused by the speed of which it rotates. Students complete a...

Students discover the different stages of mitosis by examining onion roots under a microscope, drawing diagrams of what they see, and organizing collected data in a chart and create a pie graph from their lab data.

Middle school scientists construct a working water wheel from an aluminum pie pan. Because of the sharp edges on the cut aluminum, this activity is for mature learners only. You could have your class compete to see whose wheel can lift...

The circle of life is all around us, from the black bears in the nearby mountains to the pile of dead leaves in the backyard. Encourage young scientists to take a critical look at the world around them with a set of lessons...

in this pigeon study worksheet, students "find pigeons to investigate," then complete activities, answering questions about where the pigeons were found, how many, what they look like, observing behaviors and writing questions they may...

Students study meiosis and how it leads to variation. In this genetic reproduction lesson students complete a lab activity that calculates different genetic possibilities.

Can people really measure time just by using the sun? Scholars venture outside on a nice, sunny day to build sundials and learn how people measured time 600 years ago. The class builds two different sundials while gaining practice with...

Students explore map and plotting skills by tracing the movement s of hurricanes through the Earth's systems. a hurricane map is developed from daily media reports.

Use circle time to work on counting. Kindergarteners practice the months of the year, say the full date, chart the day's temperature, count to 100, and sing the alphabet song. This kind of daily routine cultivates deep roots for...

Very young scientists circle the things on the activity that they think are living things. Most of the pictures are of non-living things. A handy activity to use during any initial discussion about living vs. non-living things.
