Students observe a demonstration of Lenz's Law using an aluminum can and a bar magnet. They hypothesize what will occur as the can is placed in water and the magnet is lowered above it on a string. Students discover the phase shift...

Students examine why humidity changes throughout the day. They study the concept of relative humidity, absolute humidity, and dew point temperature. They interpret phase diagrams and explain why relative humidity typically falls and...

In this mitosis activity, students examine the different phases of cell division and fill in key points on a notes page. Teacher master for overhead included.

Young scholars explore the changing density of water. For this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to...

In this chemical equations worksheet, students identify the reactants and the products, state what phase each is in, and state the mole ratios of all the products and reactants. Students complete 10 problems.

In this equilibrium worksheet, students read about phase equilibrium and dynamic equilibrium. They answer nine questions based on their reading and their background in chemistry.

First graders complete an experiment illustrating why the moon appears to change over time using a flashlight and ball. Students discuss the shape of the moon and identify it as a sphere. Students write a short informational piece after...

Students use computer images to explain why the Earth has seasons and examine the phases of the moon. They create 3-D images and present them to the class. They answer a series of questions at the end of the lesson.

Students begin with an overview of the Earth's interior and how volcanoes form. They learn how engineers predict eruptions. In a class demonstration, students watch and measure a mock volcanic eruption and observe the phases of an...

Students gain an understanding of matter in all of its phases. In this science lesson plan, students further their knowledge of the laws of conservation of mass, the loss in mass can be accounted for, when the gas is allowed to escape...

In this calculating joules worksheet, students read about the relationship between mass, temperature change, specific heat and energy. They find the number of joules needed to heat water in five different problems using the given...

Students investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Students perform a...

In this chemical reactions worksheet, students are given fifteen unbalanced equations and they must identify the reaction types, the phases of the products, the signs that a chemical change occurred and the sum of the coefficients of the...

Students understand basic concepts about Earth, the Sun and the Moon, such as relative movement and the phases of the moon. Through discussion, looking at pictures, listening to Native American stories, observing, and building models,...

Fifth graders study the water cycle. In this science lesson plan, 5th graders distinguish among evaporation, condensation, and precipitation phases of the water cycle.

In this time intervals worksheet, high schoolers solve 8 problems where they determine the time gamma-ray bursts last, the time black hole micro-flares are emitted, the time coronal mass ejections travel and the days between lunar phases...

Take mitosis and meiosis out of the biology textbook and onto the screen! An innovative class project prompts young biologists to create an animation movie using clay, showing the phases involved in mitosis or meiosis by...

Students investigate the effects of adding or removing a reactant or a product on chemical equilibrium. In this equilibrium lesson plan, students add or remove ions to solutions to determine the effects on equilibrium. They make...

Middle schoolers examine the life of a teenager from their own perspective and an adult's. In groups, they focus on the biological changes and how they are different in a girl and a boy. Individually, they write a paper about these...

Student explore states of matter. In this science lesson plan, learners define matter, identify the states of matter, tell about the properties of each state of matter, and demonstrate an understanding of the difference between a...

In this modeling the rock cycle worksheet, students use a sugar cube to show the phases and changes in the rock cycle as represented by the changes in the sugar cube. For each step of the experiment students indicate the part of the rock...

Students explore how they can make healthy food choices and assess how "eating healthy" requires knowledge and planning ahead. They review and discuss The Edible Pyramid as well before they complete this project online. Each student maps...

Young scholars explain the reason for the changes in season. In this lesson examining the relationship between the Earth and the Sun, students use an applet to discover how the alignment of the Earth and the Sun cause the change in...

Seventh graders construct a food chain based on pictures shown on the board. In this biology lesson, 7th graders describe the motion of particles as energy is changed. They explain how pH changes during neutralization.
