Have you ever stretched out a Slinkie so much it wouldn't go back to its original shape? Slinkies, like all springs, follow Hooke's Law. A simulation uses springs and masses to demonstrate kinetic, potential, and thermal energy. It...

Why do you weigh more in space? Each individual in your class explores this question and others as they determine the mass and weight of different objects using two types of scales. They perform conversions and discuss their...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Extinctions constantly occur, but what sets off a mass extinction event? Young scientists study the data from the previous five mass extinctions to better understand their causes. Then, they learn the impact each extinction had on our...

Here's a resource with more bounce for the ounce! Engage your physical science class with an interesting interactive that allows individuals to perform tests with a mass attached to a spring. Participants can customize the scenario by...

Extinction events have happen throughout geologic history, but only five mass extinctions occurred over the last 4.5 billion years. Scholars view fossils from a layer of sediment during an extinction event and observe patterns to draw...

Does matter really matter? Properties of matter are discussed by Sam and RJ: mass, volume, and density. They differentiate between mass and weight. They explain how to measure these properties. Make sure to teach your class about other...

A super bear is a whole lot of gummy bear. Scholars hone their estimation skills by completing an activity. Given the masses of a mini gummy bear and a regular gummy bear, they must determine the number of each needed to have the same...

The stage is set for you to guide future physicists through three forceful activities about motion. In the first, learners experiment with rolling carts to discover how objects interact. In the second, they inspect images of an object in...

How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

Use this converting metric units instructional activity to have your learners solve six word problems where they covert metric units of mass and capacity in order to arrive at an answer.

In this converting metric units of mass learning exercise, learners convert grams, milligrams, and kilograms. They solve 24 problems.

Does molecular mass affect the rate of diffusion? The simulation allows scholars to experiment with diffusion while varying the molecular mass and temperature. The timer automatically stops when a certain point is reached, making it easy...

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

Ready to teach your class about molar mass and solution concentration? Make time for an interactive resource that will challenge their reasoning and problem-solving skills. Science scholars calculate the molarity of several solutions...

Mass incarceration: A result of a tough stance on crime or racial discrimination, you decide. Academics explore the history and reasons behind mass incarcerations in the United States and its impact on ethnic communities. The...

Is history repeating itself? A riveting lesson examines the parallels between mass incarceration in the U.S. and the Jim Crow Laws of the past. Academics review Jim Crow Laws and compare them to mass incarcerations of African Americans....

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment...

Promote healthy lifestyles with an interactive that provides young learners with healthy nutrition and exercise messages. Class members plug their height and weight information into an online body mass index calculator, and hear positive...

Students identify the relationship between kinetic energy, mass, and velocity. Then they explain and graph the relationship between kinetic energy and mass. Students also predict the impact of objects of different mass and velocity on...

In this conservation of mass instructional activity, middle schoolers experiment with vinegar, baking soda, a balloon and a flask. They compare the mass of the closed system of reactants before the experiment to the mass of the products...

Teach the basics of mass spectrometry with a hands-on activity. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative abundance and...

Sometimes modeling is the best approach to working with microscopic particles. A lab investigation models a fictional element using pasta. The setup uses three different pasta types to represent three different isotopes. Learners...
