In this activity, students create a model using metric measuring tapes and atmosphere composition data. Students will investigate the major components of the atmosphere (nitrogen and oxygen) as well as the minor components which raise questions about global warming and greenhouse gases.

In this activity, students use coins to model molecules and demonstrate how mass in conserved in a chemical reaction.

In this activity, students use water, a soda can, and a straw to create a thermometer.

In this activity, students investigate and demonstrate chemical change by hollowing out the interior of a penny by dissolving the zinc inside with toilet bowl cleaner. This acitvity pairs well with the activity "Physical Change - Pennies."

Students will learn about human color perception by using colored lights to make additive color mixtures.

Students will observe how changes in temperature cause objects to expand or contract.

Students will demonstrate how heating iron to a high temperature can cause it to lose his ability to be magnetized.

Students will rotate a flat shape into the third dimension to demonstrate bilateral symmetry.

In this activity, students explore how two cylinders that look the same may roll down a hill at different rates.

Students will explore sound by creating a "telephone" out of two empty yogurt cups and string.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages. This activity also introduces learners to greenhouse gases, infrared radiation, and global warming.

In this activity, students walk a path to help them visualize Earth's immense size and structure without the usual scale and ratio distortions.

In this activity, students use an energy drink can to investigate and calculate potential and kinetic energy.

Students will repeat patterns in two and three dimensions to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle. This lesson features three investigations that are appropriate for varying grades and levels.

This website provides background information, data, historical records, hands-on activities, and graphics/media about earthquakes.

In this activity, students investigate if steel wool will weigh more or less if burned and examine the chemical reaction involved.

In this activity, students experiment with water, temperature, and light to see what makes a seed come out of its shell.

In this activity, students fold and crumple aluminum foil to investigate density and compare foil's density to water.

This activity reinforces students' understanding of shapes by creating string shapes. This activity can also be modified for grades 1 and 2.

In this activity, students interpret a graph by generating motion and speed that matches the graph. They will also create graphs that represent specific dance moves and motions.

Students will examine NASA images and images from the Neumayer Antarctic Station to graph and investigate atmospheric ozone.

In this activity, students make a record player out of simple materials and investigate how sound is produced from vibrations.

In this activity, students use differently weighted cola cans to reflect the force of gravity on other planets (and the moon).

In this activity, students measure the amount of carbon dioxide in a carbonated drink. They will work in teams of at least two to extract, collect, and measure gas (volume) from a can or bottle of cola. Students can also compare the volume of gas to the mass loss and determine the molarity of the CO2 in the cola.

In this activity, students model hot spot island formation, orientation, and progression with condiments.

In this activity, students investigate the speed of chemical reactions with light sticks. Reactions can be sped up or slowed down due to temperature changes.

In this activity, students investigate convection by using food coloring and water of different temperatures.

Students will create a sun clock out of simple items in order to tell time by the movement of shadows throughout the day.

In this lesson, students use colored candy to represent subatomic particles and make a model of an atom (Bohr model). This helps with student understanding of the sub-atomic components of an atom as well as nuclear notation of the periodic table.

In this activity, students will investigate rocks and then use their descriptive data to match with another student.

This resource describes and illustrates the varieties of mutations that are commonly seen in Drosophila fruit flies.

In this activity, students organize fasteners by their properties in order to better understand the basis of the arrangement of the periodic table of elements.
