Comparing the Density of an Object to the Density of Water
Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

Word Problems of Equal Share and Equal Groups
Explore this engaging approach to division problem solving with young scholars. They construct story problems after drawing 3 cards that give them a type of object, how many they have of that object, and the number of groups the object...
Cornell University
The Physics of Bridges
Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

Equity and Equality Lesson
Equality does not equal equity and this lesson explains why. Class members compare two images--one labeled "Equality" and the other "Equity." Using the provided discussion questions, they then develop definitions that distinguish between...

Solve Word Problems of Equal Share
Youngsters solve division word problems. They will make their own division word problems using objects in equal groups. They share how they solved their problem with the class. Division worksheets are included to support the process....

A Mass of Pennies
Learners estimate and determine the number of cents (pennies) that are needed to equal the mass of a variety of common objects. They develop a process for measuring and explore concepts related to units of measurement.

Conditional Probability and Probability of Simultaneous Events
Your statisticians examine the characteristics of conditional probability and the probability of simultaneous independent events. They perform computer activities to find probabilities for simple compound events. They examine the...

All Kinds of Numbers
Count and compare numbers and fractions using "greater than" and "less than." Learners count on by 2s and 10s and represent the end number with base ten blocks, counters, and cups. They use circle stickers to illustrate fractions and...

Word Problems of Equal Share and Equal Groups
Fourth graders solve multiplication word problems. In this multiplication problem solving lesson, 4th graders view an example of how to group objects in a word problem. Students practice solving these word problems with partners and use...
Curated OER
Fundamentals of Multiplication
Third graders examine how multiplication is a quicker and neater form of addition and how they can simulate the concept of groups and (sets) to construct the visual effect of multiplication by way of forming groups of (2's) (3's) and (4's).

Weights of Objects
Students differentiate between the weights of an object on different planets. In this geometry lesson, students investigate different weights and graph their results as it relates to the different planets. They appreciate the design of...

Sorting Candy
Lower graders sort and group objects by their different properties. They watch a video about sorting then, sort and organize candy in different groups. Young scholars compare how others sorted their candy. Finally, they decide which...
Cornell University
Buoyancy
Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Pumpkin Math
Students discover how to measure the circumference of objects. In this measurement lesson, students use a pumpkin and a tape measure to estimate and find the circumference of the pumpkin.

Viscosity: The Fluid Lab
There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...
