Students create a definition of matter. In this physical science lesson, students work in pairs to sort items printed on cards into several categories (matter, non-matter, and unsure) and agree on a definition of matter.

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.

Students study light and see what emits photons and that light can be separated onto a spectrum.  In this energy and matter lesson students identify gases using a spectrum chart. 

Students explore the physical process of melting. They observe melting ice and answer questions related to energy transfer during phase changes.

Students investigate what dissolved oxygen is and why it is important to aquatic life and what factors influence levels of dissolved oxygen in a lake. They study how to use MS Excel to make charts to show trends and correlations.

The creator of this collection of chemistry slides is clever! Electron configuration is explained as, click-by-click, orbitals are displayed and then each is subsequently filled with the proper amount of electrons. After the progression,...

How are chemical bonds similar and how are they different? Provide your young chemists with the resources to more thoroughly understand the concepts of ionic and covalent bonds. Pupils research these topics, diagram examples of each...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

A few definitions related to waves open this slide show. Note that the information only covers light waves even though the title mentions sound. Correct the title before using this resource. Another mention is a set of photos of a class...

Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...

Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.

Students investigate bio-fuel. In this investigative lesson, students create bio-fuel from vegetable oil waste. Students will analyze, predict, collect and synthesize data from their experiments with bio-fuel.

Light a fire in your pupils! Scholars conduct a flame test and observe the emission spectra of several different salts in an enlightening hands-on investigation. They use their observations to make comparisons and conclusions about the...

In this science worksheet, learners explore the learning outcomes for a unit on chemical reactions. Students define 60 vocabulary words and answer a list of questions for each topic.

High schoolers study silicon and where it comes from.  In this solar mining instructional activity students complete an Internet search of mining and a lab activity. 

Students recognize the benefits of ethanol and study photosynthesis.  For this ethanol lesson students complete an experiment that shows the procedure that starch can be hydrolyzed by salivary amylase. 

In this bonding worksheet, students read about the two different types of chemical bonding: ionic and covalent bonds. Students review ion notation and oxidation numbers. This worksheet has 24 fill in the blank, 2 drawings, and 4 short...

In this electronics worksheet, students explore the properties of semiconductors to complete 17 short answer and problem solving questions.

You may want to make a few changes before sharing this slide show with your chemistry class. For one, remove the bright blue swirly background that makes the black font hard to read. Ionic bonds are described with the use of an electron...

The carbon cycle is natural and has happened for millions of years, so can humans change it? Young scientists play the role of carbon as they travel through the carbon cycle. They complete two rounds, once before the industrial...

High schoolers will identify the factors that contribute to erosion and weathering. They will start by differentiating between chemical and mechanical weathering. They then apply what they learned by playing the online jeopardy game. Key...

Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format lesson. 

Practice electric vocabulary using multiple methods. Learners begin by watching a video that explains vocabulary related to electric currents. They match vocabulary cards to practice and then create an electric circuit. Using the...

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...
