Students observe the melting of ice. For this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.

Students explore convection. In this lesson on heat and energy, students investigate how heat moves in convection currents. They use their finding to better understand how convection currents effect the movement of tectonic plates.

Earth's atmosphere is full of different energies, from thermal to wind to electromagnetic radiation. Through the presentation, class members discover these energies and how they determine weather patterns.

How did the earth become the mass that it is now? Your young scientists explore this question through the concept of density. Their inquiries consider the impact of gravity on the formation of planets. The culminating activity of the...

Geology rocks — literally! A geology chapter offers eleven activities at four different levels. Scholars enjoy completing hands-on experiments before applying critical thinking skills following a share, process, generalize, apply,...

Students experiment with butter as a supercooled liquid in order to better explain how glass is made into different shapes.

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

Students explore the concept of density. In this density lesson plan, students determine the density of a crown and a sample of clay. They hypothesize about the densities of 4 liquids they are given including molasses, cooking oil, a red...

Middle schoolers decorate the hallways and their classrooms to represent different layers of the rainforest.  In this Amazon rainforest lesson, students watch a slide show presentation to discover the Amazon rain forest of South...

Students examine what lies within the Earth. They research and create scale models illustrating the layers of the Earth and write skits advocating a travel plan to send a probe into the Earth's mantle.

Students explore the earth's atmosphere, weather, and climate. They begin class with a discussion about weather patterns, atmosphere, and the layers of the earth. After the class discussion, students rotate through four stations to...

Students explore global warming by conducting a weather experiment. In this greenhouse gas instructional activity, students define the greenhouse effect and the impact on our ozone layer. Students utilize a soda pop bottle, floodlight...

The earth sciences are the focus for this Jeopardy-style review game. Categories include geology, space, scientific investigation, meteorology, and oceanography. Diagrams and pictures are involved with most of the questions, making this...

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Students investigate the process of glass blowing.In this simulation of glass blowing experiments students experiment how glass is formed and why not all glass is the same.

Learners investigate oil accumulation by creating a model in their classroom. In this petroleum geology lesson, students discuss where oil comes from and why it is vital to our society at this particular time. Learners cut out a 3-D...

Students will make a lava lamp. For this density lesson, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.

High schoolers consider density and how it affects sinking and floating. Students make predictions, test liquids, and observe why some liquids sink and others float. They perform experiments to determine relational causality and how...

Students explore the concept of density. They use the the formula Density = Mass/Volume, one can determine where certain liquids and objects will settle in a graduated cylinder. In addiiton, they design a process to separate the liquids.

Students use a thermometer to analyze soil temperature data to determine which soil sample is normal, and which one is permafrost. For this permafrost lesson plan, students participate in a hands on activity where they identify the...

In this deducing density worksheet, students follow the procedures to set up an experiment about objects floating in water and liquids of different densities, answer questions, collect data and complete charts.

Students investigate crude oil. In this crude oil lesson, students investigate fractional distillation and use this technique to separate two liquids.

Middle schoolers conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. They come up with an explanation for their observations about different amounts of liquids a penny...

Pupils explore water as it changes states of matter. In this physical property lesson, students use observation, measurement, and communication skills to describe changes in water as it goes from a solid to a liquid and back again.
