Ninth graders use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on....

Students identify the physical and chemical properties and explore the differences.  In physical and chemical property lesson students test polymers for the differences between the physical and chemical properties, record their...

To better understand how solar power can aid in creating desalinated drinking water, the class creates a model still. They will build a model of a solar still, make observations, and discuss how the process works. While the idea behind...

Puzzle your way through to a new understanding of area. Scholars learn about the area of polygons through equidecomposability, the idea that polygons that can be decomposed into the same set of pieces have the same area. By using...

Students observe a balloon rocket and how it relates to Newton's Third Law of Motion. In this balloon rocket lesson plan, students make a balloon rocket out of balloons, clothespins, straw, fishing line, and duct tape.

Pupils work in groups with a wooden box that is sealed shut. They make predictions about what is inside the box. Before being allowed to open the box, the groups make hypotheses, conduct experiements, record results, draw conclusions,...

Students examine the concept of radioactive dating. In this radioactive dating lesson, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.

Students explore the concept of acceleration. They determine the acceleration rate of a roller-blader and graph the results.

Third graders identify key concepts and definitions about tornados. They work in small groups of three to four to create mini-tornados. After reading Tornado Alert as a class, 3rd graders discuss tornados and fill out a KWL chart.

Students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. They come up with an explanation for their observations about different amounts of liquids a penny can hold.

Students create environments to demonstrate how earthworms interact with their surroundings.

Fourth graders go on a virtual field trip to five ecosystems. They investigate and videotape a temperate forest in the school's backyard.

High schoolers prepare successful wet mount slide of Elodea. They determine and identify environmental conditions that induce cytoplasmic streaming. They determine the positive aspects of cytoplasmic streaming. They illustrate knowledge...

Students use string, wire, weights, and a stopwatch to build pendulum clocks. In this pendulum clocks lesson plan, students use the pendulum clocks to investigate weather, climate, force, and motion.

Second graders investigate the stages in the life cycle of the butterfly. They create a picture using Kid Pix tools. They give a description of the picture that they have created.

Fourth graders discover that scientists examine evidence from around the world in order to explain global climate change. They see that records of climate change exist, and describe photographs interpreting changes in glaciers over time.

Learners study phenology, or the study of climate change. They research the Japanese springtime festival of Hanami and plot and interpret average cherry blossom bloom date data from the past 1100 years.

Students observe the effects of water on four different packing materials to determine which ones are more soluble. They then decide which material would be a good packing material to use for the environment and which may be a bad...

Students perform a simulation in which they work for a toy company and have to figure out how many marbles of different sizes can be made with the provided material. They must design their own experiment to figure this out.

Learners role several balls of different weights down a ramp and into a paper cup and record how far each ball made the paper cup move. They then answer questions that help them analyze their results and reinforce the idea that energy...

Students actively engage in the careful analysis of chromosome banding patterns and identify examples of inversion in homologous chromosomes.

Ninth graders explain waves in terms of energy transfer and describe their basic types and characteristics. They solve mathematical problems involving wavelength and frequency. Students conduct experiments in reflection and refraction.

Students formulate their own hypothesis, determine which variables are important to test their hypothesis, design an experiment in which they collect data. They utilize instruments and tools to measure, calculate, and organize data.

Seventh graders are given the opportunity to use model-building as a way to help comprehend the forces and phenomena at work in the world around them. They use both successful and unsuccessful models to make inferences, refine...
