How Can We Determine the Concentration of an Unknown Solution?
High schoolers participate in experiments to help them determine the concentration of an unknown solution. They graph a standard curve and plotting the relationship between the concentration and the amount of light needed. They discuss...
Curated OER
Aortic Stenosis Investigation
Students describe how blood flows through the heart and the anatomy of the aortic valve. They examine the condition of aortic stenosis and create diagrams of the condition in the heart. They complete experiments using the model they...
Curated OER
Chinese And Japanese Tomb Cultures
Students examine burial customs in ancient China and Japan comparing those customs to burial traditions from other cultures. This lesson leads to group creative projects of mock "tombs".
Curated OER
Graphical Determination of Density
Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.
Curated OER
You Can Be a Woman Engineer
Young scholars inspect a variety of objects from different points of view. The front, right, side, top and bottom. They then draw a diagram of that object from the point of view chosen. Also, they think of other objects and draw them...
Curated OER
Cams
Students explore plate and barrel cams. They discuss the differences between the two cams. Students identify a base and prime circle and they draw a plate cam using the provided details.
Curated OER
Area of Parallelograms
Seventh graders review the process of finding the area of a rectangle and complete a couple of examples as a class. They discuss what a parallelogram is and what the formula would be for finding its area. They listen to an explanation...
Curated OER
ndirect Measurement Technique: Using Trigonometric Ratios
Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...
Curated OER
Fences and Posts
Fifth graders use Geoboards to demonstrate how shapes can be made by looping the rubber bands over the nails. They make a triangle on their Geoboards. At least one side of the triangle should be either horizontal or vertical. The picture...
Curated OER
Squirt
Fourth graders using the idea of "how many more squirts" fill a container to develop multiplicative thinking. They also investigate the idea of conservation of volume when working with oddly shaped containers. They attempt to use...
Curated OER
Around We Go
Fourth graders investigate a range of circles, each with a different radius, diameter and circumference and assemble this information in their search for relationships.The measurement of circles and the relationships to be found within...
Curated OER
A4 Containers
Fifth graders determine which container made from a single sheet of paper has the greatest volume. They look the solutions made by three different students before working on their own examples.
Curated OER
Penny's Box
Students need to be able to calculate the volume and surface area of a cuboid as well as present a systematic list of results in order to justify the minimum case. The use of three factors of 100 is also important.
Curated OER
Bill's Badge
Students explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on students.
Curated OER
Karen's Tiles
Students investigate how perimeter changes as area changes to see the relation between area and perimeter for similar shapes. They then students answer the question if the area of the rectangle increase, does its perimeter have to increase?
Curated OER
Estimating the Live Mass of Dinosaurs
Students calculate the volume of scale model dinosaurs using a water displacement method. They use formulas to calculate the live mass each of the species of dinosaur. Then they complete and discuss a series of questions.
Curated OER
Estimating the Live Mass of Dinosaurs
Learners estimate the live mass of dinosaurs. Using dinosaur and modern animal models, students use simple displacement methods to calculate the volume of the models. They calculate the masses of each model. Learners compare the...
Curated OER
Extraction of DNA from Onion
Students experiment with DNA by isolating it from plant tissue. They investigate whole onions to prepare DNA. They complete the experiment to examine the structural characteristics of DNA.
Curated OER
Am I Neutral? pH Properties in Soil
Middle schoolers participate in a science lab to determine the pH of three different soil samples. Students conduct an experiment by creating a question, a hypothesis and then an investigation of soil samples. Then they compare colors...
Curated OER
Shapes are Everywhere
Second graders gain an understanding of geometric shapes and spatial reasoning. They learn the attributes of solid shapes in everyday activities. Students compare geometric shapes to everday objects, finding things that serve a purpose...
Curated OER
Measuring: Why Can't We All Just Get Along?
Students examine why having standardized units of measurement is important. They investigate the use of non-standard measure, twigs, while measuring the piece of tape. Next, they experiment with straws, paper clips, and rulers before...

THE TRAVELS OF BABAR: An Adventure in Scale :Building a Model Hot Air Balloon
Young scholars encounter basic facts about helium and hot air. They compare the weight and size of different materials. Students work collaboratively in teams. They create their own model balloon.
Curated OER
Science: Testing Water for Toxicity
Students investigate the potential toxicity of water samples using California blackworms to test water quality. They observe the worms' behaviors in different water samples and determine which sample has the highest toxicity. At the...
Curated OER
Float or Sink?
Students examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...
