Your routers don't seem to be routing correctly. To figure out why, pupils act like routers, talk to their direct connects in order to determine as much information about the simulated network as possible. As they learn more about...

The last activity in a nine-part series has teams create a Google Earth map using the data they collected during a field trip. Using the map, groups analyze the results and make adjustments to the map to reflect their analysis. A short...

Two versions of this handout are provided, the second with more detailed information on the same topics. Chemistry aces survey chemical reactions, heat energy transferred, and the action of enzymes by reading this resource. You can...

This optional instructional activity introduces the class to the idea of a minimum spanning tree. The activity focuses on determining an algorithm that will find the most efficient path in a network to transfer data. 

You may find this presentation helpful in setting up the classic experiment where potato wedges are used for observing the effects of osmosis. You can view the experimental setup in the text and a lab sheet in the pictures, but you will...

The second lesson in a unit of 15 introduces pupils to text compression. The class begins with discussing how they already use text compression when sending text messages. Pairs learn more about the subject as they work to compress a...

Data, data everywhere. Challenge your class to begin thinking about data, the ways people collect information, and what we can learn from this data. Class members discuss sources of data and then individuals answer questions in the...

Students examine the case of a map making expedition. In groups, they read a case study on "The Lost Gorge" in the Finger Lakes region of New York state. They examine maps and determine where the error in the map-making occured to end...

Rock exploration, so exciting! After reading the book Everybody Needs a Rock, the class makes sandwiches to better understand that the Earth is made in layers. They then use a description of the 3 types of rock to conduct an observation...

To observe preservation techniques firsthand, learners dry a flower in sand and compare cucumber slices soaked in salt water for a week with slices left out to dry in the open air. Video resources (not attached) include one about mummies...

Students participate in a role play where they play clouds, the ocean, rain drops, and more in order to learn about the water cycle. In this water cycle lesson plan, students have discussions and learn vocabulary.

Young scholars identify the elements that make up the earth's weather. Begin by having students pretend they are hiking along a mountain ridge. It's been sunny and warm all day, but you see a dark line of clouds moving from the west.

Students create a model of DNA and simulate replication with their models in an activity that uses licorice, colored marshmallows, and toothpicks. Students also label a diagram of replication and indicate major parts of the DNA molecule.

The other "Three Rs" are covered in this lesson: reduce, reuse, and recycle. Over four weeks, conservationists collect data about waste in their own homes. They combine their findings with those of other young scholars in order to...

Learners use NASA satellite data to see cloud cover over Africa.  In this seasons lesson students access data and import it into Excel. 

Students explain concepts of charge storage, how a capacitor works and how DRAM uses capacitors to store memory. They construct a capacitor and use a multimeter with capacitance meter capability to measure the stored charge in the...

An online animation demonstrates how the lock system between Lake Superior and Lake Michigan works. Pupils then construct their own models of the lock system out of shoe boxes that they bring from home. This is an educational activity...

Students examine the relationships between plants, animals, and the environment in ecosystems. They sort animal cards, collect natural materials from the schoolyard, and record an ecosystem web in the form of a poster.

Students describe and compare the layers of the atmosphere. They explain how to measure the temperature of the atmosphere. They also explain what causes the atmosphere to heat up in some places more than in others.

Young scholars determine how evidence gained from a simulated test for the presence of pesticide residues can be used to determine risk. They use peas to simulate pesticide residue testing.

Students explore how sewer systems can contribute to water pollution and perform an experiment to see how well a water purification technique can protect against water-born microbial illnesses. They compare the bacterial growth from...

Learners explore a variety of weather websites, and complete a Weather WebQuest worksheet. They read and analyze weather data, prepare a weather forecast and daily weather report, and predict the weather for the next two days.

Students are provided with drawings of planet surfaces in order to investigate different types of planetary terrain. They make observations for each planet and discuss the characteristics observed. The lesson includes background...

A visually entertaining PowerPoint on farming is here for you. Specifically, the presentation takes you and your pupils through the harvest of corn and soybeans. All of the machinery used in harvesting, storing, and sending the products...
