Students recognize the concepts of the five general types of chemical reaction: combination, decomposition, single replacement, double replacement and combustion. They practice classifying chemical equations and determine the moles in a...

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

Students investigate reaction rates.  For this seventh or eighth grade mathematics lesson, students collect, record, and analyze data regarding how the temperature of water affects the dissolving time of a sugar cube. Studetns...

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

Japan is one of only a handful of countries that constructs buildings that are almost earthquake proof. The 13th instructional activity in the 20-part series challenges scholars to build structures to test against earthquakes. With...

Does a tennis ball have energy? What about a bowling ball? Demonstrate concepts of different forms of energy forms and states with a variety of objects. Using the equations for potential and kinetic energy,...

Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on water or not, based on density, explain why some objects sink or float based on...

Students work with circles, angles and estimating angles in the night sky. For this circles and angles lesson, students practice measuring a degree using the circumference of a circle and apply the degree to determine a way to use their...

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. 

Young scholars work together to discover the flow rates of faucets and rivers. They relate their results to engineering and applied science concepts. They make predictions on the flow rate of a nearby river in their local community.

Eighth graders differentiate photosynthesis and respiration. In this biology lesson, 8th graders draw a diagram explaining these two processes. They answer a quiz after the lesson.

Learners review balancing chemical equations. In this chemistry instructional activity, students calculate moles of an unknown substance based on stoichiometric relationships in the balanced equation. They cite applications of...

Eighth graders identify the three main types of chemical bonds. In this chemistry lesson plan, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.

Eighth graders discuss the four major cycles of matter. In this general science lesson, 8th graders decide which of the four is the most important. They share their opinion in class.

Eighth graders distinguish between physical and chemical change. In this chemistry instructional activity, 8th graders observe a series of demonstrations showing physical and chemical changes. They identify the signs that a chemical...

Third graders review the scientific method and how and in which steps scientists use observations and measurements. Then as a class, they hypothesize which ramp will send the car the farthest. They break into groups and send cars down a...

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...
