Curated OER
Fertilizers, Pesticides and Health
High schoolers apply real data to create and calculate algebraic equations. Students create a visual to represent the concentration for one part per million and apply unit analysis to verify measurement computations. High schoolers...
Curated OER
Buoyant Force
Students investigate the scientific concept of why some objects float when put in a liquid solution. They apply the laws of motion and force while conducting classroom activities. Students also take notes and answer target questions to...

The Weight of Things
Students explore weight. In this math instructional activity, students predict which item weighs more and discuss how they arrived at their decision. Students weigh several items to determine which weighs more.
Curated OER
Metric Mania
Students observe how to measure in metric units. In this investigative lesson students compare different units of volume to see how things are measured.
Curated OER
Space Exploration
Fourth graders observe an empty 14 oz. clear plastic cup and measure how much water the cup can hold when it is completely full. They work in groups to fill the plastic cup, but half of the groups receive a smaller vial and the other...
Curated OER
The Portion is the Poison
Middle schoolers calculate the amount of everyday food products or liquids that would need to be consumed in order to become toxic. By using unit analysis, they calculate the amount of certain common food items that would need to be...
Curated OER
i-Density Crisis
Eighth graders determine the density using mass and volume. In this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known density.
Curated OER
Drip, Drip, Drip
Students gather scientific data and be able to utilize the data to generalize results over a long period of time. They use the appropriate tools to measure quanities of liquids and analyze the data to determine the cost of a leaky faucet.
Curated OER
Keeping Warm
Fifth graders measure the temperature of water using a thermometer. They record the temperatures of water on a chart. Students use the temperature data to determine which materials are the best conductors of heat. They discuss their...
Curated OER
Making Sense of Density
Students identify the concepts of density, mass, and volume that define the property of a substance. They also determine that the properties of materials, such as, density and volume, can be compared and measured by using rulers,...
Curated OER
Sun or Shade?
Third graders use a thermometer to measure the air temperature in several places around the school and then graph the data. They grow 3 plants in different sunlight and record the growth.

Making Up Nutrient Agars
A resource rich in information—and nutrients. Learners create agars for the purpose of cell cultivation in Petri dishes. The lesson provides instructions on how to create agars for the cultivation of different microorganisms.
Discovery Education
By All Indications
How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...

Cleaning Water
Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water filtration...
Curated OER
Quick Breads, Muffin Method Demo
Students learn what quick breads are and that they belong to the Bread, Cereal, Grain Food Group on the Food Guide Pyramid which are high in Carbohydrates. They identify characteristics to look for in quick bread products, the...
Curated OER
Photosynthesis Cookies
Students identify photosynthesis as a process through which organisms make their own food. They practice the process for writing the formula for the photosynthesis equation.
Students describe how the processes of photosynthesis and...
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...
Curated OER
Tiling Tessellations
Young scholars explore tessellations. In this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Young scholars create examples of tessellations using pattern blocks.
