"If you can't explain it simply, you don't understand it well enough" - Albert Einstein. The sixth installment of a seven-part series teaches young scientists about the importance of being able to communicate scientific research and...

Ninth graders explain how atoms and molecules form different substances during chemical reactions and how these processes require losing, gaining or sharing electrons. They correctly write chemical formulas and show how a balanced...

Students use the Five E method to solve problems. In this Five E activity, students complete math lessons using the Engage, Explore, Explain, Elaborate, and Evaluate technique. They use the Five E's with lessons on tessellations,...

Explore Snell's Law using thin films. In the fifth installment of a seven-part series, pupils solve a set of problems relating to Snell's Law and use this skill during an experiment requiring the collection of reflective measurements...

Students define the term chemical reaction, identify the reactants and products in a chemical reaction, distinguish between decomposition and synthesis reactions and construct reactions using food items.

Learners investigate energy involved for bonds to form and break. In this thermodynamics lesson plan, students experiment with chemical reactions to observe endothermic and exothermic reactions, they explore entropy and the effects of...

Middle schoolers develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Students learn the impact that genetics can have on the evolution of a population of organisms and become aware of the influence that the environment has onorganisms.

Legos in science class? Watch your pupils fall in love with this activity. After learning to measure potential and kinetic energy, young scientists create their own ramps using Lego Mindstorm sensors and software.

Students work in groups to define chemistry vocabulary including the terms reactants, products, exothermic and endothermic. They then combine the group definitions to arrive at a consensus definition for the class. Students also listen...

For this cell energy worksheet, learners answer questions about the processes of photosynthesis and cellular respiration. They compare the two using a Venn diagram.

Students explain how the food chain works. They contrast predators with prey and describe their function in nature. Students discuss how the food chain aids in keeping nature balanced. In small groups, they play a game that simulates the...
