The difference between sinking and floating may be a little salt. Young experimenters analyze the effect of salt and temperature on the density of water. They use their results to predict the effect of climate change on ocean ecosystems.

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...

Students review the three states of matter and discuss if water can change from a solid to a liquid. They watch the BrainPOP Jr. video about the states of matter and discuss if they saw water change from a solid to a liquid and what made...

Students make a simple bubble maker using two straws and string. In this art lesson, students make another bubble maker by bending a coathanger into a loop. Students enjoy making bubbles.

Students listen to the book, "Oobleck," by Dr. Suess before experimenting with mystery powders. They determine the proper ratio of powder to liquid to make the Oobleck.

Students discuss what is meant by good dental hygiene. They identify food and drinks that are good and bad for their teeth. They use an egg to represent their teeth and place it in a dark liquid overnight. They predict what will happen...

Students observe the way that a sponge absorbs liquids and discuss how we our use of natural resources affects the environment around us. They discuss the need to conserve resources so we don't run out of what we need.

Students cut an apple in half and cover half with plastic wrap. They place drops of liquid on each half and discover how our skin protects us. They answer discussion questions to end the lesson.

Students design and conduct an experiment to explore the insulating abilities of different materials for keeping a liquid in a paper cup warm. A small group of lab partners test four different materials: black paper, white paper,...

Students investigate the scientific concept of why some objects float when put in a liquid solution. They apply the laws of motion and force while conducting classroom activities. Students also take notes and answer target questions to...

Young scholars participate in a demonstration in which they must attempt to suck liquid from varying containers with straws of varying sizes. They discuss the concept of coevolution and see why this activity illustrate the coevolution...

Students make ice cream from scratch. They discuss the Food Guide Pyramid and what constitutes healthy and unhealthy food choices. Students experiment states of matter - solids, liquids, and gases. They predict each stage of the ice...

This activity explores the sense of sight, nutritional needs, and the importance of milk and dairy in our diet. Students discuss color mixing, surface tension and rainbow milk. Students actively mix three colors of food coloring with...

Students incorporate within this instructional activity scientific observations, senses: touch, sound, smell and sight, classification, states of matter and surface tension. Students make a substance and use scientific observations, as...

In this volume lab instructional activity, students are guided through an experiment to determine volume of a liquid. Kids determine water displacement. Students use a formula to calculate volume of a solid figure.

In this physical world instructional activity, students review concepts relating to the chemical and physical properties of matter, density of matter, and if matter is a solid, liquid, or gas. This instructional activity has 9 terms in a...

In this word search worksheet, students locate words related to the metric system. The word list includes deci, relative, meters, thousandth, and liquid.

In this metric measurement learning exercise, students convert units of liquid measure within the metric system. This one-page document contains 28 metric conversion problems.

In this measurement worksheet, students convert 10 metric units of measurement to standard or English units for liquids, mass, and length. This worksheet is printable and no answers are available.

Fifth graders rename measurements with cups, pints, quarts, and gallons. In this measurements lesson plan, 5th graders pour different amounts of liquid that they transfer from cups to pints to quarts and to gallons. The then have to...

In this earth's composition worksheet, learners read about the layers within the earth and they answer 3 multiple choice questions. They color a diagram of the earth's core using different colors to represent the solid metal, the liquid...

In this water-themed coloring worksheet, students view water in liquid, gas, and solid forms. Students read the sentence regarding water and color the pictures.

Students use the scientific method to study Animalia and Plantae Kingdoms. In this science inquiry lesson plan, students watch a PowerPoint about science process skills. Students complete the National Geographic bottled Eggs-periment or...

Students explore forms that water can take and examine the water cycle. In this hands-on science lesson, students participate in activities that require them to change water to a solid and back to a liquid again.
