What are calories, and how do calorie needs differ from person to person? Here is a worksheet that briefly explains how calories measure the energy supplied by food, as well as suggests the amount of food an individual should eat per day.

True or false — Double Stuf Oreos always contain twice as much cream as regular Oreos. Scholars first measure the masses of the filling in regular Oreos and Double Stuf Oreos to generate a class set of data. They use hypothesis testing...

How does radiation affect our daily lives? Answer that question and others with a lesson that discusses radiation and its use in thermal energy transfer through electromagnetic waves. Pupils investigate vaporization and...

Get lost in the classifications. Using the backdrop of the Bermuda Triangle, pupils classify it by angle and side measures. They also learn information about the triangle and its history.

Small groups use rubber bands to accelerate an Android device along a track of books. They collect the acceleration data and analyze it in order to determine the device's velocity. 

Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

As the Summer Olympics are approaching, incorporate Olympic-type games into the classroom. From straw javelin to cotton ball shot put, these games are sure to keep leaners engaged. The best part is that there is math involved! Pupils...

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Sixth graders compare and contrast mass and weight. In this physics lesson, 6th graders calculate speed given distance and time information. They construct a rocket and relate this to Newton's 3rd Law of motion.

Students analyze graphs to determine relationships between variables and rates of change. They determine the basic concepts about static reaction forces. They determine the slope and equation of a line.

Make sure to consult the teacher's handbook, Inquiry in Action - Investigating Matter Through Inquiry, for two demonstrations that can be done to introduce solubility and measuring crystal mass before having the class conduct this...

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...

Students use hands-on activities to explore transformations. They view a video segment that demonstrate how M. C. Escher employed geometry and transformations to create so many of his famous drawings.

Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

A professional-quality PowerPoint, which includes links to footage of actual landslides in action, opens this moving lesson. Viewers learn what conditions lead to erosion and land giving way. They simulate landslides with a variety of...

The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

Middle schoolers explain that while cities have unattractive features, the density of human life enables energy efficiency, mass transit, recycling, and other benefits which are difficult or impossible in rural areas. This is the fifth...

Two activities employ the use of kinematic equations for determining projectile ranges. They both require the use of a toy dart gun. Included in this resource are both the teacher's guide and student laboratory sheets. This is an...

Take a look at acceleration within the context of automotive technology. They vary the mass on a toy car and run it down a ramp, exploring Newton's second law of motion. Though this is a classic lab activity, you will appreciate the...

Fifth graders measure how long it takes to make cookies. In this measuring time instructional activity, 5th graders explore how to manage time. Students decide when to start making breakfast on time, how to calculate playing time into...

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...
