Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

Model the earth's core with a neat activity that uses science as an inquiry and step-by-step procedures. The activity acquires a lot of assistance from the teacher or volunteer helpers. 

Test the levels of vitamin C in different juices. After a lesson on the importance of vitamin C in our diets, learners use titration to determine the vitamin C content in juice. They use their experience with the titration to study the...

You matter, unless you multiply yourself by the speed of light ... then you energy. Presentation covers the behavior of light as both a wave and a particle, light versus sound, space travel, why objects have colors, depth perception,...

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

Young scientists create a simulation of Hubble's law. Introducing the Big Bang Theory using balloons and a simple lab worksheet, scholars complete a data table and perform analysis.

Eighth graders study the conservation of matter.  For this chemical reaction lesson students examine what happens during a chemical reaction and complete a lab activity. 

Using a dry cleaner bag and a blow dryer, create a hot air balloon! The materials list suggests obtaining one dry cleaner bag per student, but since this is probably inconvenient, consider doing this as a demonstration during a...

Students use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...

It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly lesson plan, learners use scientific equipment to...

In this matter and change worksheet, students answer 24 questions on topics such as elements, compounds, mixtures and chemical reactions. Students answer questions about the properties of matter such as their physical state and shape. In...

Fifth graders investigate the nature of matter and of the scientific processes associated with them in this series of lessons.

Pupils study the liquid and solid states of water. In this water states lesson, students complete three experiments to study water as it cycles from a liquid state to a solid state and back. Pupils finish with a Venn Diagram comparing...

Students examine containers and their capacity. They fill a one-cup measuring cup with water and pour cups of water into other containers. Through observation, students discover how many cups make a pint, and how many teaspoons make a...

It's time to test those skills! Assess pupils' knowledge of US history and government with short answer questions, multiple-choice items, and essays. The resource serves as a standardized test that functions well for a final exam....

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

By the 19th lesson plan in the 20-part series, scholars realize volcanoes and earthquakes are related to plate boundaries. The lesson plan extends and applies the knowledge by having individuals create a bumper sticker for one specific...
