Learners predict when an object will float or sink based on comparison of density of the object to the density of the substance in which it is placed. The access a website and sketch the object in the first column of their table and then...

Combine mathematics and science to calculate measurements of unmeasurable materials. Individuals use knowledge of density and volume to determine the thickness of the film used in production. They also apply stoichiometry to...

Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the...

Be at the top of the food chain when it comes to understanding marine ecosystems. The 21st installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates marine ecosystems, ocean zones, and food...

If objects have no heat, how do they can gain and lose it? Scholars experiment with heat, temperature, and specific heat of various substances. They create definitions for these terms based on their own conclusions to complete the fourth...

Chemistry and earth science meet in a lesson on carbon dioxide emissions. After reading about atmospheric problems caused by using fossil fuels, science stars balance equations for the burning of different alkanes. They compute the...

Once your physical science stars have a grasp of the different forms of energy, use this resource to get them putting the energy to work. Small groups choose from seven different project options and work together to build an energy...

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

Students observe water birds feeding at a local wetland, record what they see, and construct an appropriate menu for a "Waterfowl Cafe." They also play a "flocking" game.

A slide show serves as the backdrop for a lesson plan on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Students quantify the relationship between temperature, energy and heat and define an endothermic reaction. They measure the energy change caused by dissolving one mole of ammonium nitrate in water.

For this matter worksheet, students watch a movie and then compare the differences between compounds and mixtures. This worksheet has 16 fill in the blank questions.

In this atoms learning exercise, learners review protons, neutrons, electrons, molecules, compounds, and ions. This learning exercise has 10 fill in the blank and 3 problems to solve.

Eighth graders sort items as they are shown one at a time by the teacher. They attempt to identify the one physical trait the teacher is looking for (metal and not metal). After several objects have been shown and placed in groups, the...

Pupils examine the issue of air pollution. They read and analyze an article, evaluate the responses of state and federal officials to the problem, conduct Internet research, and write a letter to their senator and congressman.

Eighth graders measure temperature changes and make drawings of the interactions between matter and energy. By measuring the temperature students can conclude if there are changes in levels of energy. .

Students examine the effects of heating on various crystals. They formulate and revise scientific explanations and models using logic and evidence. Students work individually during this experiment.

Students participate in a lesson designed to illustrate these concepts using simple materials. They use Science process skills to observe, measure, predict, make inferences, and communicate while completing the activity. Proper safety...

Ninth graders participate in classroom discussions, demonstrations and hands-on laboratory activities about pure substances and mixtures with a focus on common household materials. They investigate: What is a pure substance? What is a...

Students define temperature and heat, distinguish between temperature and heat flow, calculate amount of heat energy released or absorbed in chemical process, and design procedure, through experimentation, to gather and evaluate data to...

Students, after observing the elements of a local watershed, explore the need to protect watersheds as water resources for the future. They examine the factors involved with a watershed: geology, ecology, and the effect of man's...

Students experiment with solids and liquids. In this mixtures of matter instructional activity, students combine matter to form solutions. Students hypothesize, test, and analyze the data to draw conclusions. The instructional activity...

Students identify the different types of mixtures. They identify examples of solutions, suspensions, colloidal dispersions, and emulsions through a game and basic experiments.
