Students analyze the level of acid and base in a titration. In this chemistry instructional activity, students investigate the amount of acid and base required to create certain household chemicals. They perform this activity without the...

For this acids and bases worksheet, students calculate the equilibrium concentrations for acidic solutions. This worksheet has 5 problems to solve.

Students investigate the concept of molarity and its relationship to the concentration of a solution. After mixing chemical solutions, they calculate how many moles of acid and base should be in each solution. They record their results...

Chemistry stars calculate ion concentrations, pOH, or pH in different solutions. For questions in the latter half of the worksheet, they also have to explain why a solution is acidic, basic, or neutral and solve for molarity of a solute....

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

A half-page chart compares the properties of metals and nonmetals. Properties include appearance, melting and boiling point, density, strength, malleability, ductility, heat and electrical conductivity, and the nature of their oxides....

Create a little scientific magic within your classroom! Learners mix powders and liquids and identify chemical reactions. Based on the reactions, individuals determine the identity of various powders.

Before graphing and finding distances, learners investigate the coordinate plane and look at patterns related to plotted points. Points are plotted and the goal is to look at the horizontal and vertical distances between coordinates and...

Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...

Middle schoolers review properties of materials and define what pH tells them about matter.  In this pH levels lesson, students determine whether materials are acids or bases using indicator substances.

In this activity, learners review the definitions of acids, bases, and salts. They also describe the differences between acids and alkalis and define neutralization. This activity has two short answers and one problem to solve.

In this chromosome worksheet students complete a crossword puzzle by answering questions on DNA, nucleic acids, nucleotides and RNA.  

Eighth graders, in groups, take on the role of either Biologist, Chemist, Health Scientist, or Economist. They complete a webquest in which they must decide what to do about a problem concerning the effects of acid rain. They make a...

Students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also discover several things that engineers are doing to...

In this science worksheet, students read about cells, chromosomes, and genes. Students order the following items from largest to smallest: cells, chromosomes, DNA, genes, and bases.

Students apply the rules of complementary base pairing to finding the complementary sequence to a given strand of DNA. After extensive researching, the also find the amino acid sequence encoded by a given strand of DNA.

In this biology worksheet, students identify and describe the three types of RNA, messenger, transfer, and ribosomal RNA. Then they write the key features of molecules of RNA for each form.

In this chemistry science worksheet, students identify the parts of a chemical reactions. Students name the major particles of the atom. Students apply knowledge about the atom, theories, and models.

Long strings of amino acids fold themselves into stable peptides. The simulation allows scholars to observe the process in multiple ways. Using hydrophobic, hydrophilic, or a combination of proteins in three different solutions, the...

Plop, plop, fizz, fizz, oh that one is the fastest. The teacher demonstration is the second part of a four-part series. The class observes how different pill types dissolve in simulated stomach acid. They determine which one dissolves...

How did the Ebola virus first infect humans? Young virologists examine genetic sequences from the 2014 Sierra Leone outbreak to find similarities during a riveting activity. Following similar methods used by MIT and Harvard, partners...

Why do the bases in DNA pair up the way they do? Unravel the mystery of the double helix in a virtual lab. Young scientists follow in the footsteps of Watson and Crick to determine the free energy associated with DNA base pair binding....

Need an a-maize-ing lesson to show your class how regulatory genes work? If you use the well-written resource, they'll be all ears! Biology scholars discover the gene responsible for the evolution of the modern-day corn plant through a...

Let's get a closer look at DNA and other molecular structures. The first lesson in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The resource presents...
