Students understand the dynamics of acid rain and its impact on the living and non-living environment. They hypothesize how acid rain affects water pH levels in two lake systems with differing watershed features.

Pupils investigate the pH of rain water in this earth science lesson. They collect rain water from their area and explore the pH when lime stone is added, then they will use the data collected to conjecture as to the effect of acid rain...

In this acids and bases learning exercise, students read about the differences between acids and bases and then complete a table comparing the characteristics of both. Then students determine if the given statements describe an acid,...

In this chemical compounds worksheet, students determine is compounds will act as acids or bases when added to water. Students compare basic, acidic, and amphoteric anhydrides. This worksheet has 15 fill in the blank, 2 short answer...

High schoolers investigate DNA strands. They study the sequence to determine if it is DNA or RNA and write the mRNA nucleotide sequence. After stringing the beads together to create the mRNA sequence they translate it into an amino acid...

In this biology worksheet, students work to define the nucleic acids of RNA and DNA. They answer the questions that focus upon the two concepts.

Students study acids and how they can be measured.  In this acid lesson students distinguish the properties that create strong and weak electrolytes. 

Students search the World Wide Web to locate an artistic image that inspires an aural composition. They compose a musical piece using loop-based composition software and use file management and storage techniques to archive project work....

These slides have lovely images to illustrate the Double Helix and replication.  The specifics of chromosomes within cells and the numbers and structure during different stages of cell replication are explained.

High schoolers identify auxins from their structural formulas. They understand the process of refluxing in chemical synthesis. Students perform thin layer chromatography using silica gel plates to differentiate chemical substances.
