Let your brilliance shine like the sun. Future mathematicians and scientists consider given data on the abundance of different elements in the sun. The assessment task requires consideration of how these different abundances relate to...

Balloons will go where you want them to. Young pilots first add paper clips to a balloon to make it neutrally buoyant. They then use cardboard to steer the balloon in different directions, taking air pressure into account.

Break down light into spectra. Scholars learn how atoms emit and absorb photons and come to understand how this process allows scientists to identify different atoms based on either absorption lines or emission lines. Learners then...

Space scientists investigate the cosmic phenomena in order to search for answers to possible origins of the solar system. They consider the concepts of elements and  isotopes. Data is analyzed looking at tje abundance of elements...

Archimedes' principle is practiced as chemistry learners practice computing the density of different gases, liquids, and solids. Using a chart of standard densities, they also identify unknown materials by similar calculations. Fifteen...

In this density worksheet, students calculate the density of objects given their mass and volume. They are given a table with the density of a variety of substances and given the mass or volume and must find the unknown.

In this solutions, suspensions and colloids instructional activity, students use diagrams to show how particles are different in each of these mixtures. They also distinguish between characteristics of each of these types of mixtures and...

In this metric units worksheet, students convert measurements from one metric unit to another using dimensional analysis. They must show their work to receive credit.

In this atom worksheet, chemists learn how to determine the number of protons, neutrons and electrons in an atom using the atomic mass and atomic number. They complete a chart of the subatomic particles and use marbles to represent...

After making a list of top 10 brightest stars, your class will learn to classify the colors of the hottest and coolest stars.  The spectral classes will help with understanding of nuclear fusion and the life of a star.

Starting with a recap of atomic structure, these slides continue by comparing different isotopes of uranium and explaining which are stable and which have a decay period and emit alpha or beta particles. Gamma decay is just mentioned on...

Slides and slides of emission spectra bring this topic to light for your physics class! Exited electrons returning to lower energy levels is offered as the cause of emission spectra. In summary, viewers learn that we can determine the...

An introduction to the noble gases shows how full electron shells on an atom makes an element unreactive. Your class will then develop an understanding of how sodium and chlorine react ideally because of their electron arrangement....

Element groups are located in the periodic table by blinking on and off. A slide is then dedicated to each of the groups, explaining which elements are included and what common chemical properties they share. This topic is presented in...

Study matter in a new way with a cross-curricular assignment for language arts and math. Learners answer five reading comprehension questions after reading a few paragraphs about the periodic table, properties of elements, and how atoms...

William Steig's story of a witty mouse couple will have scholars intrigued as they listen for new vocabulary words and context clues. Doctor DeSoto can be found on YouTube in case you don't have it. Emerging readers expand...

Colored boxes with white font present the basic periodic table of elements to your young chemists. All of the basics are included: chemical name, symbol, atomic number, atomic mass, and the number of electrons in each orbital. A brief...

How many planets can you name? Did you get all 13 in our solar system, including the dwarf planets, or were you surprised when you read there are 13 planets? The lesson helps scholars understand the scale of the universe including the...

Should Pluto be considered a planet or a dwarf planet? Scholars research planets in our solar system to understand their similarities and differences. It also includes memory activities related to the order of the planets. 

Raise expectations in your classroom and assess learners through the provided performance tasks. Class members must apply concepts learned throughout the year, providing a good measurement of how well they understand the...

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

Quickly assess basic understandings of statistics and probability. The resource contains five quick tasks from the probability and statistics domain. The questions range from finding simple conditional probabilities to measures of...

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.
