Work together to stay afloat. Using a paper boat, pupils connect properties of materials to their usefulness. They test different paper to determine how many pennies each boat will hold and learn that combining materials with different...

In this solar system worksheet, learners use foldable models they made of the planets to answer questions about each planet. They answer questions about the theories and predictions made in our history about the solar system and answer...

The Hardy-Weinberg principle is the focus of this concise slideshow.  Some vocabulary definitions are given on the first 2 slides, and the rest are given over to examples of the Hardy-Weinberg theorem. Calculations of the H-W...

Your Algebra learners analyze and solve an exponential equation in this popular, real-life model of the cooling of a liquid.  

How does your class measure up? Young scientists create a scale drawing of the JOIDES Resolution in a collaborative activity. The lesson incorporates mathematical principles with deep-sea exploration to focus on enhancing measurement...

Young scholars discover what Mendel uncovered in his famous pea experiments. They form explanations for the result of crossing a true-breeding round pea plant with a true-breeding wrinkled pea plant (the F1 generation) and for the...

Fourth graders study flight and compare various flights.  In this measurement lesson students complete a lab activity and record measurements. 

Fourth graders investigate the principles and uses of gears, and examine how gears can be used to alter the direction of motion or the speed of an object. They observe two cars with different sized wheels roll down an inclined plane,...

Fourth graders compare and contrast gliding flight and true flight. They investigate the basic principles of aeronautics. The class participates in activities to observe lift and the effect of air. Students design and fly their own...

The five agents of evolutionary change are reviewed in this slideshow. Definitions of common terms involved with populations and equilibrium are given, and there are some presentations of Hardy Weinberg equations for common examples of...

High schoolers develop an understanding of the mole and molar masses of elements. In this mole lesson plan, students use beans to find their relative masses and draw parallels to the atomic masses of elements. High schoolers work in...

Students investigate insect camouflage and mimicry. For this animal science lesson, students discuss how camouflage helps an insect survive. Additionally, students use the included template to color and cut illustrations of insects....

Sixth graders examine the layers of the Earth and the changes that take place on a daily basis. They look at the layers of a boiled egg to relate them to the layers of the Earth.

Students list four ways to identify trees. For this tree identification instructional activity, students use tree identification techniques such as leafs, bark, wood grain, soil type, and climate to create tables and graphs.

Student's measure sporadic meteor activity.  In this physics and astronomy lesson, 11th graders construct a dipole antennae, and build, test and wire a full wave diode rectifier between the dipole antenna and the laptop. 

Students use their basic knowledge of dendrology concepts and terms.  For this tree leaf lesson students divide into groups and determine which characteristics go with what plant. 

Learners investigate the potential toxicity of water samples using California blackworms to test water quality. They observe the worms' behaviors in different water samples and determine which sample has the highest toxicity. At the...

A very lengthy page from friesian.com discussing Bohr's theory of electronic energy levels and the explanation of commonly observed atomic emission line spectra. The concept of a photon and Einstein's observation of the photoelectric...
