Learners explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.

Students experiment with Thin Layer Chromatography to separate pigments found in flower petals.

Pupils participate in a demonstration to test the different densities of plastics, and suggest a method that plastic waste can be separated and collected.

Students conduct a simple conductivity meter to test the ionic or non-ionic nature of water samples including one from their home.

Students explore how the density of an object is determined and determine what a "physical property" is. They demonstrate how science can be applied to police work.

Twelfth graders work in teams to design a method of recycled plastics purification by flotation. They base their design on the concept that different kinds of plastics have different densities and keep overall costs and purification time...

Students examine the work of scientists and determine how they test their theories.

Students 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 their...

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...

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.

High schoolers 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.

Young scholars 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. Young scholars...

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.

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...

Young scholars 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...

Pupils discover the Archimedes principle through a buoyancy experiment. They measure the water displacement of a lump a clay which is denser than water then reshape the clay into a bowl which floats but displaces more water.

Students explore calories. In this instructional activity about calories, students practice counting and recording calories. Students use a sample Calorie Calculation Chart to record how many calories consumed in one day. Students do an...

Learners observe how to measure in metric units.  In this investigative lesson plan students compare different units of volume to see how things are measured.

Young scholars study the parts of a cell.  In this chemistry lesson students complete an activity in which they make as much slime as they want. 

Students explore physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five days...

Students create three dimensional shapes using concept maps. For this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Students use specific dimensions to create a box. In this geometry lesson, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.

Students identify the pattern in a problem. In this geometry lesson, students make predictions, collect and analyze data. They apply the idea of scales and measurements to the real world.

Students investigate the relationship between volume and mass in different liquids such as vegetable oil, rubbing alcohol and water. They measure the mass of several different volumes of each liquid and then graph the results as well as...
