Students mix two different solutions to become more familiar with molecules and polymers. In this chemistry lesson, students decide whether or not the reaction between two solutions is chemical or physical. Students then observe the...

Learners observe how to distinguish observations form inferences.  In this examining inferences lesson students list observations relating to the activity and discuss the importance of them. 

Students predict, observe and draw conclusions while working on an experiment with "slime." Students accurately record observations and draw conclusions about the experiment.

Second graders culminate their study of shapes by describing the shapes using the proper mathematical descriptors.

Fourth graders examine the properties of geometric solids. Given geometric figures, they brainstorm observations. In groups, 4th graders identify solids and discuss the physical properties. Each student creates a Venn diagram and...

Students draw upon their prior knowledge of the density of water and practice writing a hypothesis, making an observation, and analyzing data while watching a density demonstration.

Students build a hydrometer to measure the densities of fresh and salt water samples. They record the water temperature and density and use the temperature, density, and salinity conversion graph to locate the salinity. Finally,...

In this Geometry Chapter 13 review activity, students complete 20 multiple choice questions and 1 bonus question regarding volume, dilation, and midpoint and distance between points of 3D objects.

For this ESL 2D and 3D shapes worksheet, students assemble the booklet and read different types of shapes. Students then respond to 5 fill in the blank questions, 1 short answer question, and 5 matching questions regarding the...

In this rocket worksheet, students calculate the burn rate for solid rocket boosters depending on exposed fuel area and burn depth. This worksheet has 2 problems to solve.

In this density laboratory worksheet, students complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.

In this geometry worksheet, 10th graders respond to journal prompts related to prisms and classifying solid shapes.  The two page worksheet contains nine questions.  Answers are included. 

Students compute the surface area of 3 geometric solids to determine the shape of package that would require the least amount of paper to wrap. In this geometry lesson, students work on a two-question assessment embedded in the plan. The...

Students create nets of cylinders. In this geometry lesson, students calculate the surface area of cylinders and other solids. They show their understanding of three-dimensional shapes by solving problems.

Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.

Students explore physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five days...

Students design a wheel that can go down the ramp with the smallest moment of inertia. In this technology lesson, students construct their model using a computer program. They calculate the moment of inertia of their finished product.

Students explain the importance of water in our daily lives. In this aquatic science instructional activity, students identify different ways to purify water and make it potable. They design and construct a water filter based on...

Students participate in Density Discoveries, which is a hands-on learning opportunity for students to find the mass, volume, and density of solid matter.

Students determine the solubility of salt in water at three different temperatures and graph the results. They use the following skills: observing, inferring, and graphing.

Fourth graders measure volume, circumference, and height of fast food cups, find which one has the greatest volume, and compare/contrast those measurements to discover any correlations between them.

Fifth graders determine volume and density through their knowledge of mass, volume and density.

Sixth graders measure and investigate the densities of several objects. They, in teams, determine the mass and volume of each of the 5 objects and record the measurements in the data table.

Sixth graders explore the water displacement method to determine the volume of solid objects such as rocks, nails, and marbles.
