Young scholars estimate the live mass of dinosaurs. Using dinosaur and modern animal models, students use simple displacement methods to calculate the volume of the models. They calculate the masses of each model. Young scholars...

Learners need to be able to calculate the volume and surface area of a cuboid as well as present a systematic list of results in order to justify the minimum case. The use of three factors of 100 is also important.

Young scholars examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph...

Students construct a barrel or other curvy container and then estimate and gauge its volume.

Fourth graders using the idea of "how many more squirts" fill a container to develop multiplicative thinking. They also investigate the idea of conservation of volume when working with oddly shaped containers. They attempt to use...

Students use the lesson, "Squirt", to support students' development of multiplicative thinking. Squirt encourages students to anticipate multiplicative measurement relationships, e.g. three measures of A fit in B, by partially filling a...

Following this procedure, eager engineers construct a working model of a piston system, similar to that in an internal combustion engine. Perfect for STEM or automotive technology classes, the activity comes complete with analysis and...

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly lesson plan, learners use scientific equipment to...

Young scholars perform an experiment to measure the density of tap water vs. salt water.

Middle and high schoolers perform transformations. In this web based lesson, learners explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.

Students compare and convert units of measurement within the United States customary system and within the metric system by baking cookies. Students discuss how to double the cookie recipe, how to make only half of the recipe, and how to...

Some weddings have flowers in a unique, unnatural color to match the theme. Young scientists take part in this process to learn about the function of the xylem as they observe colored water moving through a flower. Then, they experiment...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

How does radiation affect our daily lives? Answer that question and others with a lesson that discusses radiation and its use in thermal energy transfer through electromagnetic waves. Pupils investigate vaporization and...

How much time does it take to jump over three balloons? Pupils calculate the speed of tasks that require different motions. They determine motions for tasks such as walking, skipping, hopping, and jumping before creating a...

Assist your class with correctly calculating the values for force, work, and power as they determine the amount various activities require. They gather data and participate in a group discussion to compare results upon conclusion of the...

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Energy is just energy, right? Explain various forms of energy to your young scientists by using an interactive experiment that contains common objects to demonstrate complex concepts. Pupils conduct experiments for radiant, thermal,...

Step right up! An engaging research-centered lesson, the third in a series of six, has young archaeologists study the amazing animals of the Cambrian explosion. Working in groups, they profile a breathtaking and odd creature and learn...

Wrap up a lesson on surface area with a resource that asks scholars to use the idea of wrapping paper to investigate surface area. They draw representations of rectangular prisms on graph paper to find the areas of the respective...

Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...

Model good modeling practices. Young mathematicians first learn about cross sections and solids of revolution. They then turn their attention to special right triangles and to the Laws of Sine and Cosine.
