Oversize Tires
Big vehicles require some big tires. Given a picture of a flatbed hauling a large tire, scholars discuss and estimate the size of the tire. They then use information and video about the tires to estimate the height of a vehicle that uses...
Curated OER
Triangles
This unit enables scholars to apply the rule for area of a triangle (area equals half base times height). They practice multiplication and division strategies as they calculate areas.
Futures Channel
Folding Circles
Students investigate properties of circles. In this geometry activity, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.
Curated OER
Down The Line
Learnersinvestigate three-dimensional shapes. In this geometry instructional activity, pupils calculate the volume of cylinders using the given dimensions. They create a formula base don observation before using the real formula.
Curated OER
This Is a Stick Up
Learners create a sundial and track the movement of the sun throughout the day. Modifications to the lesson are provided for both lower and upper elementary students.
Curated OER
Periodic Motion - The Pendulum
Students experiment to determine the period of a pendulum. For this periodic motion lesson, students use different pendulums to determine their periods. They use various amplitudes to determine its effects on the period.
Curated OER
Proving Pythagoras
Students prove the theorem of Pythagoras. In this Pythagorean Theorem instructional activity, students define the different parts of a right triangle. They use the Pythagorean Theorem to solve for the missing sides and angles of a right...

Effects of Friction on a Moving Block
Young scholars investigate how friction affects the movement of a block across surface areas. They test five different kinds of surfaces—smooth surface, wax paper, a paper towel, course, and fine sandpaper. They predict and record the...
Curated OER
One Size Fits All?
Young scholars describe the differences between an estimate and a guess. They create reasonable estimates based on comparison and activities. Students explain how estimation is helpful in showing the relative size on a scale. They...
Curated OER
Bird Eggs
Students perform an experiment with different types of bird eggs to determine what factors make them strong and able to stay on a cliff without rolling off.
Curated OER
The Tangent Ratio
Students calculate the tangent ratio given a right triangle. In this trigonometry lesson, students use a right triangle and the Pythagorean Theorem to solve problems.
Curated OER
What Does The Heart Do?
Students study the relationship between the heart and circulation. In this circulatory system lesson, students read the "What Am I?" article about the heart and discuss. Students draw a heart and lungs, discover how blood is pumped...
Curated OER
Classroom Meteorologists: An Experiential Approach to Learning about Seasons and Weather
Students examine several concepts about weather in the seven lessons of this unit. This year long activity helps students to gather data seasonally about wind, clouds, precipitation, and temperature. Earth's three climate zones are...
Curated OER
Acceleration 2
In this acceleration worksheet, students experiment with varying amounts of mass to observe the effects on the force needed to move an object. Students apply Newton's Second Law of Motion to describe the relationship between mass and...
Curated OER
Surface Area and Volume
Students are introduced to the notion of surface area and volume, learn the terminology used with surface area and volume and have experimented with the surface area and volume of different prisms.
Curated OER
Barge Building: What Floats Your Boat?
Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.
Curated OER
Soda Straw Weaving
Students investigate the loom and weaving process. In this weaving lesson, students use soda straws to make a bracelet or a bookmark. Students use the over-under pattern of weaving.
Curated OER
Area & Perimeter
Students define area and perimeter. They demonstrate understanding of the concepts concretely, with manipulatives, and describe with words, their strategies and thought processes.
Curated OER
Cell Size Changes
Students examine the behavior of living cells treated with different types of stimuli. They watch an online movie, examine wet mount slides under a microscope, take an online quiz, and analyze data.
Curated OER
Volume and Mass: Identify the Attribute
Young scholars rotate through five studying stations related to the attributes of volume and mass. They manipulate objects to explore mass, compare two masses by pushing and lifting, pack materials and fill containers, and pour liquids...
Curated OER
Identifying Variables
In this variables worksheet, students are given seven experiments that they read and identify the independent variable, dependent variable, control group and standardizing variable.
Curated OER
Map Adventures
Students explore the relationship between a scale drawing and actual distance. In this mapping instructional activity, students use an amusement park map to determine distances and what they would be like in real life.
Curated OER
Crime Scene Documentation
Learners become forensic investigators. In this crime scene lesson, students go to the science lab which is the "scene of the crime." They collect evidence such as fingerprints, "blood" evidence, chromatography, footprints, and more.
Curated OER
The Elements
Students watch video, The Elements, research information about elements using both the Internet and CD-ROM program, and create atoms out of gumdrops and licorice.
