You're on solid ground if you decide to use the resource. A simple activity has young engineers investigate the problem of liquefaction. A battery placed on dry sand will stay standing—but not if scholars add water to the cup.

Second graders explore states of matter when they change a liquid to a solid. Working students make ice cream in a zip-lock bag.

Students explain that photosynthesis is a process that plants use to convert light energy into glucose. They summarize photosynthesis as a chemical process in which the plant uses carbon dioxide and water to form glucose and oxygen.

Seventh graders examine the functions and roles of membranes in cells. They discover the differences between plant and animal cells.

Sixth graders analyze and compare a cell's tissues, organs and organ systems. They watch a video reviewing the body systems and design poster boards showing their functions.

Young scholars observe an experiment using common household chemicals to simulate a volcanic eruption. In small cups, they follow the teacher's instructions to make their own volcanoes. After watching a Brain-pop video, students complete...

Learners match definitions with vocabulary words and learn basic facts about matter. Then, they see how to determine the physical characteristics of matter. They determine the mass, volume, and density of objects using appropriate tools...

For this static electricity worksheet, middle schoolers use balloons, flannel cloths, and a plastic bag to create static electricity. Students then fill out 3 tables and answer 3 short answer questions.

Students observe osmosis, a cellular process that normally can't be observed without a microscope, and use scientific method to observe osmosis in a chicken egg.

Eighth graders, in groups, explain the difference between physical and chemical changes.

Seventh graders analyze and identify the role of the cell membrane and nucleus. They create flash cards to help them review cell structures. They also compare plant and animal cells.

Fourth graders study the functions of the human eye and how it processes information.

Fourth graders examine how to conduct a reliable scientific experiment so that the results are valid. They compare and contrast the reaction of Alka-Seltzer tables, one whole and one crushed, and time how long each takes to pop the top...

Students participate in a lab activity in which they extract DNA from a strawberry. After mashing the strawberry into an even, smooth puree inside a bag, they add extraction buffer and mix the strawberry with the buffer. They filter...

Second graders observe matter in all 3 states : liquid, solid and gas, in an ice cream soda. In teams, they are given ice and teams compete to be the first to melt their ice. Winner gets the ice cream soda. They draw examples of 3 states...

Fourth graders make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix...

Fourth graders create cartoon characters which compare and contrast two types of cells: nerve and muscle. Cartoon characters show how these two cells are similar, how they are different, and the relationship between the two cell types.

Second graders explore how plants produce oxygen.

Students discuss radiant energy from the sun, performing a simple experiment with sun glasses and bright light to demonstrate the concept. Students further participate in simple in-class experiments to demonstrate: air density as it...

Students determine the amount of sugar in various types of gum. They chew a piece of gum until it loses its flavor and leave it to dry in order to weigh it and determine the amount of mass lost, and describe an experiment to determine...

Student observe and quantify the respiration that occurs in yeast-molasses cultures. They complete an effective experiment in order to examine how to think critically about the results.

Students identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.

Learners assess what a dichotomous key is and how it identifies objects in a group through a process of answering yes/no-type questions about certain objects. They examine an interactive graphic key on sea turtles and then create their...

Middle schoolers build an apparatus to look at how yeast cells grow by converting food to energy. They observe yeast both with and without food and see how yeast produces carbon dioxide.
