Bone Density Math and Logarithm Introduction
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 plan of seven is devoted to logarithms and their properties.
Curated OER
pH and Red Cabbage Juice
Middle schoolers review properties of materials and define what pH tells them about matter. In this pH levels lesson plan, students determine whether materials are acids or bases using indicator substances.
Curated OER
Chemistry Practice
In this chemistry practice worksheet, students select the correct response to the given questions. Students apply knowledge about the states of matter, finding vapor pressure and atmospheric pressure.

Light Intensity Lab
Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

Size and Scale – Learning about Measurement
Can you visualize one billionth of a meter? It's not easy to understand the scale of a nanometer. Learners use a hands-on lesson to develop an understanding of the size of a nanometer in comparison to common objects. They walk away with...

Calculating pH
In this pH learning exercise, 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...
Curated OER
Falling Hydrogen Ions
Tenth graders define pH and use it to interpret amounts of hydrogen ions in a solution. In this hydrogen lesson plan students read about acid rain, divide into groups and present their information to the class.

Teach Engineering: Bone Mineral Density and Logarithms
Students examine an image produced by a cabinet x-ray system to determine if it is a quality bone mineral density image. Students write in their journals about what they need to know to be able to make this judgment. Students learn about...

Teach Engineering: Light Intensity Lab
Students complete this Beer's Law activity in class. Students examine the attenuation of various thicknesses of transparencies. From this activity, students will understand that different substances absorb light differently. This can...
