In this uncertainty activity, students solve 8 problems of addition and subtraction using the rules for uncertainty notation. They do the same for 7 problems for multiplication and division. Students add, subtract, multiply and divide...

Students explore nuclear scientists.  In this nuclear science research lesson, students choose a scientist who has contributed to nuclear theory, research his/her life and accomplishments, and write a paper. Students generate...

Learners examine their eating habits. In this nutrition instructional activity, students will journal their eating habits over a period of three days. They will use a diet analysis web page to determine the nutritional factors of their...

Students understand the concept of a scientific model and how it relates to climate change.  In this obsesrvation and gathering data lesson students design a trial and error model using PowerPoint. 

Students investigate how geologic sequestration reduces carbon dioxide concentration in the atmosphere. In this earth science lesson, students simulate oil mining in the lab. They write down their observations and complete the lab report...

Students examine the different techniques that may be used to reduce carbon dioxide in the atmosphere.  In this ocean pollution lesson students divide into groups and complete a lab to see how the ocean holds carbon dioxide.

Students examine the importance of proteins including their function and structure.  In this protein lesson students play a game to help them better understand proteins.

Your science class reads a silly story in which a mad scientist makes absurd conclusions about an experiment that he conducted. One at a time, he cuts off a frog's leg and commands it to jump. With three, two, and one leg, the frog...

In this periodic table worksheet, students complete a paragraph containing facts about the periodic table by filling in 18 terms from a word list.

Each of the tables on these pages has a list of substances that pupils need to identify as having a particular chemical or physical property. Some of the choices include kinetic or potential energy, heterogeneous or homogenous mixture,...

Students experiment to see how the solubility of a solid changes as water temperature changes. They graph the results of the solubility tests.

Learners determine the heat energy needed to vaporize (boil) one gram of liquid nitrogen.

Students calculate the volumes of regularly shaped objects from measurements of their dimensions. They use several formulas and measure different objects to calculate the density, volume, and mass of the objects selected or assigned.

Students have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...

Students comprehend that the Cartesian diver is a dropper and the water and air inside it. They vary the volume of the air and the amount of water, the diver can be made to be either more or less dense than water. Pupils squeeze the...

Students experiment with floating the spaghetti, the gas functions like a life preserver. Pupils comprehend that a person is slightly more dense than water. They comprehend that a life preservers are made of low-density materials. The...

Students comprehend that hot water rises up through cold water but cold water does not rixe in hot water. They comprehend that water at temperatures above 4oC decreases in density with increases in temperature. Students answer lab...

Students watch as the teacher demonstrates: if a single liquid is placed in a U-shaped tube, the level of liquid on both sides are the same. When the mass is greater on one side than the other, liquid is pushed from one side to the...

Students (teachers) complete the activity, they should not come in contact with Alka-Seltzer. They comprehend that the density of a gas can be calculated from its mass and volume. Pupils calculate the volume of gas generated by...

Students practice determining liquid densities in a short, hands-on lab activity. Students use a graduated cylinder to measure out 100 milliliters of a liquid, find its mass using a balance, and record measurements in a data table....

Pupils review that air is a form of matter. They investigate how air takes up space. Pupils comprehend that they cannot see air, it takes up space and has mass, therefore it is a form of matter. Students investigate how to show that...

Young scholars observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Middle schoolers identify special properties of matter (absorbency, hardness, brittleness, malleability, and elasticity). They define the term matter. Pupils investigate some of the special properties of matter to aid in classifying...

Students list individual properties of solids, liquids, and gases. They examine that some properties have more than one state of matter. Pupils consider whether shaving cream, is a solid, a liquid, or a gas, or some combination.
