Coin Comparisons

Students investigate owl pellets.  In this math measurement and animal survival lesson, students observe, weigh, and examine the contents of an owl pellet.  Students record observations and data, then draw conclusions about the prey of...

Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...

Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for comparison.

A step-by-step demonstration of how to use a spring scale is presented to the viewers by a gentle female narrator. For your flipped classroom, you can have learners view this at home and then come to class to practice measuring weight...

Students utilize a balance scale. In this applied science lesson, students compare the weights of two objects using an elementary balance scale. Students balance the scale with weights to find how heavy an object is.

Students create their own balance to determine a difference in the weight (and composition) of cents made in different years.

Students use a balance and gram cubes to measure several different objects. They then record their results on a data chart and answer questions about them.

Students make direct comparisons between objects using balance and spring scales. They also are encouraged to estimate which object is heavier by holding the objects before using the balance scales. Comparing the masses of objects is the...

Students concretely illustrate and define a macromolecule, observe the unique behavior of polymers and relate to their knowledge of molecules, and use the scientific process to determine the difference between Newtonian and non-Newtonian...
