Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Learners complete five center activities that in order to determine the attributes of length and area. They study the vocabulary associated with measurement of length and area. They use blocks, play dough, wrapping paper, and footprints...

Learners investigate the ingredients and creation of chewing gum.  In this scientific method lesson, students make predictions about what will happen to the mass of a piece of gum as it is chewed by a human.  Learners graph the...

Students explore the water cycle. In this water cycle lesson, students simulate the water cycle by placing an ice cube in a Ziploc bag and observing the changes which occur over time. Students record the mass of the Ziploc bag and record...

Second graders identify the attributes of various shapes and estimate the weight of the objects. For this geometry lesson, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.

Students calculate the length of the classroom using non-standard units of measurement and estimation. Using a cracker box, they discuss measuring various objects in the room as a class, and independently estimate and measure the length...

Students determine the area of two objects by superimposing one on the other. They compare and order the area of different shapes by covering a larger shape with similar smaller ones. They complete these activities as different stations.

With the help of the Area Officers and Perimeter Patrol, you learners will develop a better understanding of area and its relationship to perimeter. First, they view a video clip from Cyberchase, and then they visit a website to...

Learners explore the different arrangement of air molecules in high and low air pressure masses. They compare the temperature of high and low pressure masses and discover how a barometer works.

Second graders sped the day exploring about balance by playing with and making balancing toys. They discover how varying the amount and position of mass affects the toys' balance. Pupils explore gravity and balance while playing with the...

Students examine and discuss the differences between clocks they are shown. Using the internet, they research how people used to tell time before clocks. They review what the long and short hand on the clock represent and practice...

In this second grade lesson your class will practice telling time. The goal is to tell time to five minutes using an analog clock. Your young students count by 5 minute intervals and discuss elapsed time. 

Pupils become familiar with the various coins in our money system as well as amount of each coin. They help develop their ability to count change and find different ways to show equal amounts.

Students listen to story, "The 100-Pound Problem," compare their weight with character in story, and weigh different classroom items using nonstandard units and standard units. They experiment with different items that can make scale...

Second graders distinguish between and use nonstandard and standard units of measurement, use appropriate tools and techniques to measure length and width, and record and interpret data using graphs.

Students estimate how many children in their class it would take to equal the mass of one adult bear. They then weigh and record their measurement on a chart to check their estimate.

Students experiment to observe air and its mass.  In this air lesson, students use the scientific method to complete experiments that demonstrate the properties of air. Students view a video as follow-up.

Second graders investigate the properties of solids and discover how to classify them. Using rulers, they measure various solids on display. In groups, they play an identification game where one students names a location, such as the...

Second graders discover that everything is made of matter. they determine the properties of liquids and that like solids, liquids can be grouped or classified according to properties or qualities. they assess that solids have a definite...

You're going to wish you had a watermelon for this lesson! Class members read about watermelons and make a salad in class to sample. They also perform estimates, measurements and calculations on a watermelon. They predict what percentage...

Second graders investigate volume through the use of measuring cups. They complete a variety of measuring tasks using kitchen measuring cups. Students accurately measure the volume and compare the results.

Students performing a scene about pirates and spend time making a measuring meters incorporating the main character, Captain Blood to add interest. They use meter sticks measuring items from the play and record their answers in meters.

Students investigate Mexican holiday celebrations and compare them to American Christmas holidays. They conduct a Mexican Christmas Scavenger Hunt. The lesson uses a streaming video in order to engage students in the main objectives.

Students complete a Cirlce Map about time. They recall times during the grouchy ladybugs travels, and add dots on ladybugs using turn-around facts. Pupils correctly sequence the events of The Grouchy Ladybug. Students compose new...
