Students study the properties of the physical and natural world. In this properties of the physical and natural world lesson, preschool students work at discovery tables to see how simple machines work, what happens when items are put...

Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...

Fifth graders explore how coral polyps increase the chances of egg and sperm meeting after being released into the vast ocean waters.

Young scholars 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.

Integrating art into your classroom every day just got easier. This fantastic idea provides 43 strips intended to keep early finishers busy and to bring art into the classroom. You cut the strips, put them in a drawer, and have early...

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. 

In this critical reading activity, students read a passage regarding salt then answer three questions based on the reading.

In this chemistry quiz worksheet, students complete a set of 10 multiple choice questions covering a variety of chemistry concepts.

Young scholars participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.

Fourth graders focus on fluency by reading the book Charlotte's Web. In this reading strategies lesson plan, 4th graders partner read, do guided reading, and independent reading to increase fluency. Students use Venn Diagrams,...

High schoolers study Archimedes' Principle, flotation and the reaction of buoyant forces and explain the relationship between density and flotation.

Students examine the effect of foreign species on various habitats. In groups, they identify the population dynamics of the zebra mussel. They calculate averages and graph data from Seneca Lake in New York. They develop hypothesis...

Students study pictures of seeds and the conditions in which they grow during their study of archaeobotany. They infer ancient plant use by looking at archaeobotanical samples. They determine the change of plant use by interpreting a...

In this activity, students will learn about density by determining how to make an egg float in water. By the end of the lesson, students will understand that density and weight are different and that density matters in floatation. They...

Try these fun physics experiments. Find out how you can make an egg float in water or if an egg is raw or cooked without breaking its shell and many other fun curiosities.
