High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

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.

Pupils explore the physical properties of density. In this hands-on lesson, students calculate density and distinguish between intensive and extensive properties.

Students role play as paleontologists who make inferences about the weight of dinosaurs. They use models and the density of water to make these inferences.

Students study the water cycle and how the sun is an important factor.  In this water cycle lesson plan students investigate how to desalinate water and explore the different densities of fresh versus saltwater.

Students experiment with skeletons. In this bone health lesson, students analyze, construct, and perform comparative investigations with bones. They make inferences about the structure and function of various bones. This lesson includes...

Students calculate the volume of scale model dinosaurs using a water displacement method. They use formulas to calculate the live mass each of the species of dinosaur. Then they complete and discuss a series of questions.

In this math/science worksheet, students find the balance point of a variety of objects, and complete ten problems. Students look at sketches of objects and calculate the balance point, and also use meter sticks and weights. This is an...

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...

Students differentiate between the weights of an object on different planets. In this geometry lesson, students investigate different weights and graph their results as it relates to the different planets. They appreciate the design of...

This is a guided inquiry activity in which students use simple lab procedures and discussions to develop and apply the concept of density. Students collect and graph data which they use to explore the relationship between mass and...

In this lab activity, students are required to write a procedure to be followed in a simple lab process and record the results they get from following that procedure. They then exchange procedures with another lab group, which will have...
