Class members discover how mathematics can quantify the behavior of light waves with the fourth installment of a seven-part series that teaches future engineers about equations related to refraction, including the equation to...

Students examine stoichiometry. In this chemical reaction and mole instructional activity, students complete an experiment based on readiness levels to explore that changes are quantified in chemical reactions.

Is qualitative or quantitative research more convincing when it comes to climate change? In the eighth lesson during this 21-part series, scholars begin by performing a quantitative analysis of deforestation and urbanization. Then, they...

"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

Students study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Get some laparoscopic training without the pain with an activity that challenges class members to find out what it is like to perform laparoscopic surgery. Teams perform three different tasks and quantify their performance. The...

Common sense says that the farther a planet is from the sun, the longer the orbit. Kepler turned common sense into his third law by quantifying this relationship. Classes explore Kepler's Third Law through an interactive tutorial. They...

Small and large are relative terms; what's the best way to quantify them? Young scientists take on that challenge as they complete an interactive activity to explore size. They build structures during their exploration and begin using...

Why is star gazing easy on some nights and difficult on others? Pupils aim to quantify the answer in an enlightening astronomy lesson. After collecting images from an online robotic telescope, they measure the brightness of images using...

Leaf toughness can add to its herbivore appeal. Learns design an experiment to quantify leaf toughness and then perform their procedures. They follow the experiment with a set of questions that ask them to think about how leaf toughness...

Students examine the effects of a stimulus on a reflex by changing the strength or force at which the stimulus is applied. Students chart and record data of the lab using video tape.

Students are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier probes...

Student observe and quantify the respiration that occurs in yeast-molasses cultures. They complete an effective experiment in order to examine how to think critically about the results.

Students describe and quantify the motion of toy cars. For this motion lesson, students observe a battery powered toy car on a flat surface and a standard toy car on a sloped surface. They write their observations, measure average...

Students are able to download, install, and use Image J image analysis software to quantify change over time in satellite images. They access and download satellite images for specific locations and times. Students set a scale (spatial...

Students enact the life cycle of a sessile animal and quantify the possibility of survival under the conditions given. They then present to the class a new adaptation which will increase the animals chance of survival.

The learners construct a heating curve and explain its components. They perform calculations. They review phase changes and quantify Energy differences. They review phases of matter and their energy content.

Students are able to transcribe to scale the plant features of a common landscape. They determine true north and south and collect and record data on a table. Students calculate a rating for and describe a definition of insulation and...

Students are introduced to the concept of Energy Conservation with the example of: Tony Hawk seems to defy the conservation of energy as he keeps reaching new heights on each pass on the halk-pipe. Actually, Tony is supplying the extra...

Young scholars examine structural features.  In this life science lesson students complete an activity and quantify the impact of various modifications. 

Young scholars describe the importance of structural features that increase surface area in a coral reef habitat.  In this investigative lesson students quantify the impact of modifications on surface area in model habitats. 

Students quantify the relationship between moles and mass. They comprehend that ammonium nitrate is used as a fertilizer and an explosive. Students study the chemistry of ammonium nitrate and consider the advantages and disadvantages of...

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

Believe it or not, it is possible for liquids and solids to get along! A hands-on lesson has individuals explore dissolving properties of candies in water. They complete an activity guide to record observations about different candies...
