Fourth graders explore the different types of ways to measure the distance between Florida and Japan.

Fourth graders work in a group of 4 to make rectangle with a 12m length of string. They discuss its perimeter and how they would calculate its area. Then another group of 4 make another rectangle and estimate if the area would be greater...

Fourth graders research a Florida fish to determine its length. They display this information on two index cards, which are cut to the shape of the head and the tail and attached to a string that they measure and cut to the correct...

Students collect and analyze data about wind speed. They build a Lego wind sail and measure the wind speed with a rotation sensor. They use software to analyze the data.

Students explore the concept of big and small. They collect objects from the classroom, sort them by size, and create a graph using Duplo stacking blocks.

Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.

Students discuss the relationship between technology and manufacturing. They then use their ideas to construct a model of a paper board carton package. Next they view a PowerPoint presentation to learn about the history of packaging...

Students sort Lego Duplo pieces after determining the attributes to classify them by. They work in pairs to sort a group of Duplo pieces and explain their process to others.

Young scholars study the techniques of building a bridge. They explore different type of bridges and then plan and build a bridge to specified instructions. Students draw plans, keep a budget, and prepare balance sheets during their...

Third graders estimate the volume and mass of one marshmallow using appropriate standard units. They design and carry out an investigation to find the average of volume/mass of one marshmallow.

Students observe the process of transpiration in leaves. They measure how much water a leaf gives off in a 24-hour period, calculate the volume, and answer discussion questions.

Students work together to complete an experiment calculating the amount of board footage in a tree. They record their data and answer questions at the end of the lesson. They create their own hypothesis as well.

Young scholars 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.

Fourth graders swap local soil samples with another school and examine the differences. They research soil properties, identify organisms that live in soil, create and maintain a biome of soil decomposition and design a poster to present...

Students design and implement an experiment intended to measure and analyze the air quality of a particular location. They focus on looking for ozone and particulate pollutants.

Students explore the size of a kilometer and the time it takes to cover this distance. They develop a concept of a km. They measure a distance of 1 km and the time taken to cover it.

Learners examine a variety of real life situations in which they must access information, select an appropriate formula, and calculate an answer. A rectangular piece of grass provides an opportunity for the exploration of this...

Students begin the experiment by mapping and calculating their school parking lot. They calculate the volume of water falling on the lot and map the route the water runoff takes. They discuss the roles that humans play in affecting water...

First graders complete a variety of experiments with solids, liquids and gases. They read books about matter, identify the characteristics of solids, liquids and gases and the sort and classify a variety of matter. Students make...

Fourth graders investigate a range of circles, each with a different radius, diameter and circumference and assemble this information in their search for relationships.The measurement of circles and the relationships to be found within...

Students explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on students.

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..

Students use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.
