Seventh grade scientists weigh in on the concept of density. In a nutshell, they participate in the following activities: Measurement of the mass and volume of fruit in order to compare densities Measurement of the mass of oil and water...

In this coal formation worksheet, students read and informational sheet about coal formation. Students are given 5 short-answer questions regarding what they've read.

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures. 

In this chemical change worksheet, students review physical changes such as evaporation and condensation before working with chemical change. They conduct an experiment with vinegar and baking soda before recording the chemical changes...

Students experiment to show the three forms of water. They watch a "hand" made of ice as it melts observing and drawing what they see.

Students observe changes in water. In this lesson about water and its forms, students perform an experiment to determine how water changes. Students analyze what causes water to be solid, liquid, or gas. Students record their...

In this theromochemistry learning exercise, students review the kinetic theory of gases and the three phases of a substance. Students calculate how much heat is required to raise a certain mass of solution a certain number of degrees....

Learners explore the six phase transitions between gases, liquids and solids for a variety of elements. Each group of students focuses on a different element, investigating its physical properties during each of the six phase transitions.

Young scholars study hummingbirds and how they use Newton's law.  In this motion lesson students complete several activities and view videos of hummingbirds. 

Students differentiate the three states of matter. In this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

What can one learn about a planet based on a small surface sample? Learners will explore artifacts from a mystery planet and see what they can determine about the planet based on the evidence in front of them. 

Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...

A slide show serves as the backdrop for a lesson on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations and...

Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

Model the earth's core with a neat activity that uses science as an inquiry and step-by-step procedures. The activity acquires a lot of assistance from the teacher or volunteer helpers. 

Test the levels of vitamin C in different juices. After a lesson plan on the importance of vitamin C in our diets, learners use titration to determine the vitamin C content in juice. They use their experience with the titration to study...

You matter, unless you multiply yourself by the speed of light ... then you energy. Presentation covers the behavior of light as both a wave and a particle, light versus sound, space travel, why objects have colors, depth perception,...

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

Young scientists create a simulation of Hubble's law. Introducing the Big Bang Theory using balloons and a simple lab activity, scholars complete a data table and perform analysis.
