Ninth graders take a rectangular box (e.g., a cereal box) and cut it up to make a new, cubical box with the same volume as the original. In so doing, they will discover that because the cubical box has less surface area than the...

Students watch as the teacher demonstrates: if a single liquid is placed in a U-shaped tube, the level of liquid on both sides are the same. When the mass is greater on one side than the other, liquid is pushed from one side to the...

Students experiment with floating the spaghetti, the gas functions like a life preserver. Pupils comprehend that a person is slightly more dense than water. They comprehend that a life preservers are made of low-density materials. The...

Young scholars observe and compare heat loss in various objects with surface area-to-volume ratios and transfer this comparison to the physical characteristics of animals in their environment. In small groups they conduct an experiment...

Students explore the examples of innovative technology found on the AT&T Labs Technology Showcase Demos website. They look at communciation patterns. They write in their science journal the problem it is intended to solve and a...

Middle schoolers investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.

Youngsters discover ways to estimate. They will use two jars with large and small items and estimate the number of items. Then record their estimate and explain why they answered the way they did. They try this experiment with different...

Primary learners participate in activities that help them explain how different things are measured. They create their own access number chart.

Student measure mass to discover how pennies have changed in their composition. In this measurement lesson, 8th graders investigate through an open-ended problem to discover how the US pennies composition changed in the 1980's.

We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...

Sometimes the simplest experiments leave the biggest impression! Introduce young chemists to the Cartesian Diver by having them make one of their own. Use the Diver to further their study of liquids and gases, as well as compression.

The human body can regulate itself through sweating and resting. Learners with visual impairments discuss how the body changes when it is under stress and what it does to regulate itself. To start, kids use talking thermometers to take...

Upper graders investigate how the Seventh Day Adventists are objectors to the practice of war. The lesson plan covers the Civil War and examines the church's position about the practice of war. The research extends to modern wars and...

Did you know you can conserve water by drinking tea instead of coffee? Learn about other products that use larger amounts of virtual water in an online lesson. Pupils complete a series of questions to test their understanding of the...

Fourth graders identify the characteristics of a simple physical change. They describe objects by the properties of the materials from which they are made. Students discuss the different states of matter and their distinct physical...

Students discuss the subject of coins and heads and tails. They work in groups to solve Fran's problem concentrating on the fact that the coins are in a row. Any group that finishes early can try the Extension problem.

Students learn the relationships between the different properties of a gas and use previous knowledge and make predictions. They predit and explain certain phenomena of gases using their chemical knowledge.

Students compare their desired portions with the actual serving size. In this lesson on serving size, students compare their desired portion of a given food with the actual serving size listed on the Nutritional Facts label.

Practice makes perfect when it comes to reading fluency! Walk your emerging readers through a familiar passage, slowly pointing to each word to keep every learner with you. While looking at a projected passage, scholars read one word at...

For this density and buoyancy worksheet, students read about the equation to find density and practice finding the density of substances. They read about buoyancy and match 10 terms with their definitions related to density, buoyancy and...

In this buoyancy worksheet, students read about the principles behind objects floating including density, buoyancy and Archimedes' Principle. Students complete a buoyancy lab where they use a balloon and water and a film canister and...

Learners explore how fish are able to move easily from one depth to another in water.  In this fish lesson students create their own balloon fish. 

Students examine geologic time to scale. In this geologic time lesson, students create a time-scale metaphor that shows some of the Earth's important events. Students present their metaphor to the class.
