Walk your class through the journey water takes once it leaves your kitchen sink, all the way through the water cycle. Demonstrations support your lecture. This plan is thoroughly written, but ideally you would follow it up with water...

The plan is that future physicists take an "Energy Misconceptions" quiz before completing a series of activities that are focused on energy concepts. The activities, however, are not outlined in this resource; only the quiz and detailed...

Eighth graders examine avalanches after reading excerpts from John Muir's book, "The Yosemite." In small groups, they conduct experiments with flour, sugar, and potato flakes representing different snow consistencies. Then, 8th graders...

Young scholars examine water quality and how to improve it, how to measure it and how it relates to human activities.  In this water quality lesson students sample water from different sources, and test the samples. 

Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...

Students design and conduct an experiment on unknown solutions after studying descriptions of indicators and the way in which they identify acids and bases. Students must gather, organize, and analyze data as well as make inferences...

Eighth graders determine the presence of starch and sugar in unknown solutions. This task assesses students' abilities to observe, record and interpret data, classify, generalize/infer, construct data tables, and identify sugar and...

Students design and conduct an experiment to determine which of three solutions contain starch or sugar. This task assess students' ability to make simple observations, design simple experiments, utilize indicators, and make generalized...

In this grade 3 addition and subtraction word problems worksheet, 3rd graders read the examples, then solve 7 addition problems, 7 subtraction problems and 7 mixed problems.

Tenth graders test usefulness of a model Earth by comparing its predictions to observations in the real world.  In this landforms lesson plan students construct an island from a contour map using model clay then analyze the...

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

Time is growing short. Teams work together to identify physical properties of rocks in order to determine the properties that would best suit their cavern shelter design.

Starry-eyed astronomers draw different views of the Moon in order to introduce its phases. Then they experiment with a ball and a lamp to recreate the phases. A demonstration ensures every pupil understands the process, and the...

It's a race to the finish! Which ice cube will melt the fastest? Scholars discover the effect thermal energy has on melting ice. They experiment with melting ice cubes on different materials and learn that even at a consistent...

Ignore the full moon, it's just a phase. Young scholars observe and record the moon during a full cycle before learning to predict future phases. Then the instructor leads a discussion on the other solar system objects that...

How do the laws of motion work in space? Learners explore Newton's laws of motion in different experiments as part of the Christa's Lost Lessons series. They rotate around the room in three stations to experience each law in action using...

Why do rocks break down over time? Learners explore this concept by simulating physical and chemical weathering of different types of rocks. They use an abrasive to demonstrate physical weathering and acid to demonstrate chemical...

Mammals are some of the newest organisms to appear on Earth. Young scholars complete an activity that results in a timeline showing the appearance of different types of living organisms. Provided with a list that spans from prokaryotes...

Teams design and build a windmill, under budget, that can lift an object. The groups evaluate and reflect on their own design, then on those produced by other teams. The goal is to determine which design is the most...

Take part in a fun experiment and hold an impromptu bouncing contest with your class. Young scientists heat and cool balls before bouncing them to determine whether temperature changes affect how they bounce. The set of...

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

What does it cost to keep the lights on? Through a hands-on activity, class members use a watt meter and determine the amount of energy different types of light bulbs use. The class then determines the financial and environmental...

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...

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...
