The whole class discusses the differences between the two clocks: digital and a clock with hands. They discuss the differences between the hour hand and minute hand. Students are taught telling time to the half hour. They are introduced...

The video clip that comprises the warm up is not available, but the related article from The New York Times and the movie trailer for Aliens of the Deep are, leaving enough material to make this a fascinating lesson on deep-sea...

How can you tell what an owl has eaten? Study the food chain and flow of energy in an ecosystem by dissecting an owl pellet and noting the bones found inside. Additionally, the lesson includes a game about consumers and producers with a...

What's the best way to record temperature over a long period of time? Scholars learn about collection of weather and temperature data by building thermistors in the fourth installment of the 10-part Discover Your Changing World series....

Third graders investigate the events of geological time using a chart called a "Clock of Eras". For this geological events lesson plan, 3rd graders compare a standard clock to a geological clock. In addition, students consider periods...

Learners demonstrate that the movement of the sun causes shadows which were used as the first indicators of telling time.

How does locally grown produce sold at a farmer's market compare to a more complex industrial system in the way they each affect the environment, people, and the economy? Pupils explore the different types of food systems and how they...

Get your class outside to observe their surroundings with a lesson highlighting weather patterns and seasonal changes. First, learners take a weather walk to survey how the weather affects animals, people, plants, and trees during...

Young chefs follow the set-by-step instructions of a recipe and use their prior knowledge of the body parts of a spider to make edible spider cookies.  After completing a pre-writing graphic organizer they then write a "how to"...

What can shadows tell us about the changing season? Over several months, astronomy learners record length and position of an outdoor object's shadow, such as a flagpole. They apply the data to a growing hypothesis and note the...

Exactly what do groundhogs know about weather? Not as much as your science students will after completing these lessons and activities that cover everything from the earth's rotation and the creation of shadows, to cloud...

You can't tell by the title, but this is a functional periodic table of elements. Incorporating bright colors, lucid text, and easily operated features, this application serves as a valuable reference tool for your chemistry class.

In the last portion of the six-part unit, teams perform an experiment with gold nanoparticles to determine which sport drink has the most electrolytes. The nanoparticles are used as chemical sensors and fluoresce in different wavelengths...

An informative presentation covers motion, metric system, conversions, graphing of coordinates and lines, speed, velocity, and acceleration problems, as well as mean calculations. This is the first lesson in a 26-part series.

Reinforce concepts and encourage learner engagement with a collection of math games, science experiments, and cross curricular activities. In one fun resource, learners sort objects, keep a diary of everyday fractions, play a game using...

Students investigate how energy travels through glass. In this energy usage lesson, students conduct an experiment in which they decide if window film affects how much energy travels through the glass. Students use a journal to make...
