Students identify and create simple geometric shapes and describe simple spatial relationships. Through discussion, hands-on activities and show and tell, they identify geometric solids in real life and create graphs of commonly found...

Students discover math measurements by creating a skit with classmates.  In this geometry instructional activity, students utilize objects in a paper bag and index cards to create a short skit focusing on debate over the size of the...

Students explore physics by conducting a class experiment. For this gravitational force lesson, students define several scientific terms associated with force. Students utilize a styrofoam cup and marbles to simulate a satellite crashing...

Students explore the solar system by conducting Earth science experiments. In this Sun lesson, students identify the different seasons on Earth and discuss their purpose and cause. Students create a sundial and observe the changes to...

Students compare sizes. In this math lesson, students complete activities that require them to compare the sizes of their bodies to those of their classmates.

Fifth graders use the Internet to use an interactive program which helps them explain the Internet better. They take a tour of a computer museum and focus on how the Internet works through an exhibit.

Place value reading skills are the focus of this lesson. Students are given an example of Pluto's orbit distance from the sun to introduce the concept of the billions place value. Students are then given four numbers in the billions, and...

Learners define an arc and calculate its length. In this geometry lesson, students find examples of arc in the real world. They show their understanding of arcs through problem solving.

Students identify several common birds through field observations, preserved specimens and personal experience. They classify the species and choose one to research. They draw a migration map and participate in a project that benefit...

Students practice multiplication facts, answer simple math questions from two, five, and ten times-tables, explore concept of halves and quarters, complete worksheet containing range of shapes to make shape picture, and sort data and...

Students discuss and give examples of Newton's three laws. They then answer questions in reference to Newton's three laws. One example of the questions that students answer is: A water-skier typically uses a 75 foot tow rope. The skier...

In this comparing weights worksheet, 2nd graders compare and contrast the weight of three different coins and then calculate the answers to eight questions.

Rounding numbers to the millions can be tricky for many young mathematicians. Students work with numbers that are rounded to the nearest thousand and round them to the nearest million. There are six sets of problems altogether.

Learners participate in various activities that increase their understanding of and ability to solve problems with fractions.

Learners explore the transit of Venus and the information that this minieclipse provides about the distance between the Earth and the sun. They create their own astronomical units.

First graders explore the day and night sky and complete a page for the number 9 for their counting book.

High schoolers download NASA Hubble Space Telescope views of star-forming regions in nebulae and look for evidence of planetary systems forming beyond our own solar system. They hypothesize about mysterious objects in NASA HST images.

Students understand that a spreadsheet can be used to find the best scale to use in a model. They place the distances of the planets of the solar system to the Sun in one column of the spreadsheet. Students try different scales so that...

Students discuss situations when it is useful to know exact weight of object as opposed to estimated weight, estimate weight of various items, weigh them on scale using ounces and pounds, and compare their weights on Guess Your Best...

Students observe and describe, both orally and in writing. the different forms of water on the surface of the Earth and measure the approximate size of an iceberg. They also estimate and measure the amount of ice that floats above the...

Students examine a message sent from outer space and do their best to interpret its meaning. In this problem solving lesson, students investigate a code sent to them from "outer space." The students collaborate with their classmates to...

Students identify the relationship between chords, secants and circles. For this geometry lesson, students calculate the length of the chords. They sketch the secant lines on a circle.

First graders explore why the sun and moon seems to disappear and reappear creating day and night.

Students use coordinate graphs in order to identify objects and their locations. They are shown how to plot the x and y coordinates and then are given values to be plotted during guided and independent practice. Students are assessed on...
