Students work in a mini lab where they measure the temperature every 30 seconds for several minutes as water is heated. They are asked what makes liquid different from a solid. Students view a PowerPoint on the model of liquids,...

In this mixtures pre-lab worksheet, students compare and contrast suspensions and colloids and solutions and colloids. Students describe the Tyndall effect. This worksheet has 10 short answer questions.

In this water testing pre-lab worksheet, students describe positive ions, precipitate, and the Tyndall effect. This worksheet has 14 short answer questions.

Students make observations of a bouncing ball and study how it travels.  For this height lesson students complete a lab activity and describe and explain the motion of the ball. 

Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.

Learners determine how scientists measure pollutants in food and the environment. Students discover how scientists remove one material based on its physical properties. Learners figure out how much of a pollutant is present after...

Students complete a variety of activities surrounding minerals, crystals, and mineralogy. They locate common minerals on a world map, complete a lab in which they identify the chemical and physical properties of various minerals, etc.

Young scholars observe and compare heat loss in various objects with surface area-to-volume ratios and transfer this comparison to the physical characteristics of animals in their environment. In small groups they conduct an experiment...

Young scholars examine carbon dioxide and determine the impact of greenhouse gases on the earths spheres.  In this pollution lesson students complete a lab activity to see the impact of gases on the environment, 

Fourth graders engage in a research project to increase their ability to conduct experiments, interpret data and discuss results in a scientific paper. After doing a lab which simulates effects of acid rain, pairs of students write a...

Students take a close examine animals' skeletons to see how their pelvis and femur work together for movement. By investigating their skeletons students discover the placement and functions of our own bodies. They use owl pellets in this...

Students identify the six types of energy. They write journal entries about each type and give examples. They participate in a lab activity in which the different types are examined as well.

Students examine how heat passes through a pane glass window.  In this energy transfer lesson students complete a lab activity.

Students examine how soil holds together and what the effect of particle size and water content is on soil.  In this engineering lesson students complete a lab, record their observations and discuss what they learned. 

Students are able to build an understanding of linear motion. They are able to define and calculate the speed and acceleration of various objects. Students are able to differentiate betweeen instantaneous speed and average speed. They...

Students compare different types of pressure sensitive adhesive tapes. They fevelop and carry out tests for variables affecting the force needed to peel tape off a surface. Students analyze the time needed to peel the tape with different...

Students examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.

In this energy lesson, students create calorimeters out of soda cans and use them to calculate the amount of energy stored in different types of wood.

Students define, identify and illustrate the parts of an atom, and investigate the Bohr atomic model. Students watch a multimedia presentation to understand an atom's parts and their functions. In groups, they create a model of an atom...

Students study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...

Students address common misconceptions concerning reflection, light and mirrors. They investigate light reflection in mirrors and determine how light is transferred to the eye. In addition, they make predictions and then test them...

Fourth graders experiment to find the effects of exercise on the heart rate.  In this exercise and heart rate lesson, 4th graders create questions about exercise and heart rate. Students use the scientific method to test and analyze...

Students construct their own battery made of lemons. In this electrochemistry lesson, students explain why lemons conduct electricity. They perform a series of experiments to investigate its conductivity.

Students identify principles behind acid-base reactions. They predict factors that may affect an acid-base reaction. Students identify questions and concepts that guide scientific investigations.
