You definitely want to check out this mole! Chemistry scholars experiment to observe an unobservable quantity with an engaging lesson plan from K20. Partners collaborate to determine what's inside an opaque box, then complete a series of...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Why do some items feel colder when they are the same temperature? How should you keep your soda cold? What makes the wind blow? These are just some of the things middle schoolers discover when completing a lesson on...

Learners of light will construct a contraption in which light is passed through a prism and shone into a box. The temperatures at different points along the path and outside of the path of light. The intent is to imitate William...

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

How do green plastics reduce waste and environmental pollution? Budding scientists create and test a variety of compounds used in green plastics during an insightful experiment. Beginning with startling statistics and ending with...

Students use a microcomputer connected to a light sensor and temperature probe to explore the reflection and absorption of radiation for different surfaces. Students follow instructions in this guided inquiry based lab and are then asked...

Students are taught that plants produce oxygen underwater, and they design an experiment that test this question. They discuss whether plants give off oxygen, and how to measure this. Students measure the increase in dissolved oxygen...

The United States is the world's largest producer of biofuel. During an in-class investigation, young scientists produce their own biodiesel. They burn a sample of it to determine the heat of combustion. Then they discuss the...

Seventh graders investigate scientific methods to solve problems. They demonstrate creating data tables and graphs. They study the role of a scientist and the importance of safety in a science lab. They distinguish between an...

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

Students explore physics. In this science lesson, students discuss physics in their everyday lives. Students complete a physics worksheet.

Learners work in a mini lab where they measure the temperature every 30 seconds for several minutes as water is heated. They are asked what makes liquid different from a solid. Students view a PowerPoint on the model of liquids,...

Fourth graders expand their knowledge about how the physical properties of a substances can be changed. They are given multiple opportunities, using first-hand experiences and familiar objects in different contexts, to identify...

Students examine the interrelationship between trees, soil and people focusing on urban areas. They collect and analyze data about trees in their research area.

Ninth graders explore the concepts of motion, velocity and acceleration through graphing their own movement using LoggerPro. They become more familiar with the computer technology. Students explore graphing in real time and graph on...

Third graders gather together as a class and share any facts or words about the science unit "Weather Elements". They listen to the story/poem, "Listen to the Rain" and recall any weather related words from the story.
