In this worksheet on the life cycle of the butterfly, students look at 4 pictures representing the life cycle stages, and choose words from a word box that match each picture. Students then number the pictures in the correct order of...

Students investigate how plants grow by analyzing pumpkins. In this agricultural lesson, students read The Biggest Pumpkin Ever by Steven Kroll, and draw pictures of a pumpkin in each of its growing stages. Students measure and dissect...

Sometimes the simplest experiments leave the biggest impression! Introduce young chemists to the Cartesian Diver by having them make one of their own. Use the Diver to further their study of liquids and gases, as well as compression.

Archimedes' principle is practiced as chemistry learners practice computing the density of different gases, liquids, and solids. Using a chart of standard densities, they also identify unknown materials by similar calculations. Fifteen...

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...

Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

Students participate in an experiment about the weight of water. They work together to discover that seawater is more dense than fresh water. They also determine which objects float and sink.

First graders write about vehicles that float.

In this Archimedes' principle instructional activity, high schoolers answer 13 questions about the concepts of Archimedes' principle such as water displacement, buoyancy and force. The answer questions from a lab they did in class to...

Students experiment with objects of different densities. In this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar to...

First graders examine the water cycle through readings and experiments. In groups, they conduct interviews with others and use the information to create a chart displaying the various uses of water. After brainstorming lists of ways to...

Students use density to identify what metal a gold colored weight is made of. They use a spreadsheet to graph the experimental density of common metals and compare the know densities to their calculated density of the known metal.

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

In this plate tectonics worksheet, student answer 15 multiple choice questions about plate movement, types of boundaries, collision of plates, continental plates, and the lithosphere.

Students discover how seeds travel from their parent plants in search of water, sunlight, and nutrients, and conduct experiments in which they note characteristics that encourage seed dispersal by means of wind, water, animal carriers,...

Students experiment with floating the spaghetti, the gas functions like a life preserver. Pupils comprehend that a person is slightly more dense than water. They comprehend that a life preservers are made of low-density materials. The...

Learners study the ocean and its characteristics.  In this oceans lesson students complete a lab activity and are able to predict temperature of certain depths. 

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...

Eighth graders determine the density using mass and volume. In this science lesson plan, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of...

Students experiment with water density, temperature and salinity. In this water lesson plan, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

Learners perform experiments to examine whether trash can float, blow around, or wash away. The effects of these characteristics on the presence of marine debris in the environment are then discussed.

Students will perform experiments to examine if debris will float, or blow in the wind. They discuss the effects of these characteristics on marine debris.
