What do logarithms have to do with bone density? Scholars learn that the equation for bone density includes logarithms. The majority of the third lesson of seven is devoted to logarithms and their properties.

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

A fun activity to demonstrate the very complicated and intangible concept of a curved universe. The instructions for creating a Mobius Strip, and therefore, curved space is given. The six questions ask for conclusions about this movement...

Properties in measurement, pressure and viscosity of solids, liquids, and gases are the main topics covered in this slideshow. The explanations of Pascal's, Bernoulli's, and the Venturi effects are very clear. Easy to understand diagrams...

For this math worksheet, students read the examples for using the techniques of mathematical modeling. They draw the angles in order to simulate the reflection of light while using a concave mirror.

In this scale image activity, students use an image taken by the LRO satellite of Mare Nubium to determine the scale of the image, the diameter of the smallest crater and a comparison scale drawing of a house.

Perform data analysis on energy consumption to apply algebraic expressions to the real world. Learners will write and solve equations that answer various questions from residential power use. They will collect data at home and calculate...

Students investigate the concept of Ohm's Law and how it is used when finding a solution to an equation. They use properties of equality in order to find the solution for the variable. Students also apply a formula to real life problems...

Fifth graders build objects using various materials. They estimate the weight of the object using individual building pieces. Then they weigh the actual object and then tear it apart and weigh the pieces. They compare the two weights.

Do you separate your trail mix before eating it? Then you've been separating mixtures your whole life! Scholars model a contaminated soil sample using trail mix and estimate the percentage of each component. They consider how to clean up...

Learners identify the different types of bridges. Using the internet, they research information on how they are built by completing a scavenger hunt. Locating a specific area, they determine which type of bridge would be appropriate and...

Students examine and compare traits of humans and crocodiles.  In this crocodile lesson students use a ratio to estimate the height of a person and compare that to a crocodile. 

For this magnetosphere global exploration worksheet, students read about the instrument on board a satellite launched by NASA called the Radio Plasma Imager. This imager detects echoes from plasma clouds. Students calculate the distance...

Students explore ruby-throated hummingbirds.  In this cross-curricular hummingbirds lesson, students listen to the book The Mystery of the Missing Hummingbirds and choose related topics to research with a partner. Students draw or...

Learners design their own Science experiment. For this science experiment lesson students create a hypothesis related to matter and test it. They displayed their data in a graph.

Students identify different woods based on their density. In this density lesson plan, students use a triple beam balance to find the mass and a metric ruler for the volume. They look through various wood blocks and identify what type of...

Learners perform a review assignment in 3 portions to review chemistry compounds, formulas, and equations. The assignment consists of several different portions that can be used as assessments. The majority of the lesson plan is composed...

Students are introduced to basic aerodynamics through a discussion of thrust and drag and a hands-on activity. They examine the forces of thrust, drag, air pressure, aerodynamic shapes and Newton's Third Law Of Motion.

In this pH worksheet, students are given information and directions as to how to calculate the pH of solutions. They use their calculators to find the pH of given solutions and apply what they learned about identifying acids and bases.

Students investigate Nanotechnology. In this physic's lesson, students evaluate a hands-on model made from chocolate syrup and pretzels to determine the advantages of size.  Students weigh chocolate syrup to determine it's wait...

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

Students research volcanoes. In this volcanoes lesson, students visit websites with worksheets about the terms for volcanoes and volcanic eruptions in the world. Students complete the work online and play a game for volcano names.
