In this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into a...

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

Fifth graders compare and identify variables that affect the rate of a chemical change using Alka-Seltzer, water, ice, and hot water. They time how long each variable takes to pop the canister into the air, and record the results on a...

Students view a demonstration on Newton's Laws of Motion using a soda can.  In this Newton's law lesson students discuss what they learned from the demonstration.

Seventh grade scientists weigh in on the concept of density. In a nutshell, they participate in the following activities: Measurement of the mass and volume of fruit in order to compare densities Measurement of the mass of oil and water...

Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...

Young scholars conduct an experiment. They review how to use the scientific method to conduct an experiment with white carnations and food coloring. They create a hypothesis and test it to better understand how plants get nutrients,...

Students watch the teacher do a demonstration of density with diet and regular soda. Note: try this first, as different types of artificial sweetener have different densities. Students discuss density and volume. They discuss "Relational...

In this review of physical science worksheet, students use recall to answer multiple choice questions about electricity and chemical changes. Students answer 25 questions.

Youngsters compare the heat-holding abilities of three different cans by insulating two with different materials and measuring the temperature change of hot water over a 20-minute period. 

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

In this solutions instructional activity, students review types of solutions, concentration and saturation of solutions, and suspensions and colloids. This instructional activity has 10 fill in the blank, 7 multiple choice, and 6 short...

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

Students 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...

Students define volcanoes and why they erupt. Using baking soda, vinegar, and soap detergent, students create and observe their own volcanoes erupting. A brain-pop video can be used to follow-up the activity (found on website).

Students investigate about acids, bases, and pH and relate this information to the problem of acid deposition. They use pH paper, students test common household substances to determine whether they are acidic, basic, or neutral. Pupils...

You know that liquid nitrogen turns into a gas at room temperature. Place some in a two-liter bottle for a physics demonstration of the ideal gas law. Beware, however; this is a dangerous demonstration! Not to mention that you may not...

Learners explore pH levels of different substances. In this lesson about pH, students work together in three to four groups to test substances. moving between three different stations performing tests on the substances to determine...

Students study various aspects of air. In this science lesson plan, students discover that air occupies space, understand the visual effects of air, and explain how air exerts force.

In this solutions worksheet, students will review 9 vocabulary words associated with solutions including mixtures, elements, compounds, and dissolving. Students will complete a word puzzle in this worksheet.

In this chemical reactions activity, learners read about the differences between physical and chemical changes in substances. Then students identify situations as either an example of physical or chemical change. Learners learn how to...

In this chemical and physical change worksheet, students read about the differences between substances going through physical changes vs. chemical changes. They are given examples of each and evidence to look for in chemical changes....

In this ideal gas law worksheet, students watch a demonstration using liquid nitrogen, a plastic 2 liter bottle and a garbage can of water that excites students to use the ideal gas law to solve problems. Students analyze the results of...

Meteorology or earth science classes reach for the sky with this lesson plan! You will need to purchase a Fizz Keeper® device and temperature strip for each lab group if you want them to perform this as an activity rather than you doing...
