In this matter worksheet, students watch a movie and then compare the differences between compounds and mixtures. This worksheet has 16 fill in the blank questions.

Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...

Students examine estuaries in Delaware. They, in groups, gather samples of water to find organisms and identify them.

Fourth graders discuss density.  In this floating golf ball lesson students complete a lab activity on density while working in groups. 

In this literacy activity, students look for the words that are related to the concept that is reviewed in the sheet. They also acquire new vocabulary.

In this chemistry practice activity, students select the correct response to the given questions. Students apply knowledge about the states of matter, finding vapor pressure and atmospheric pressure.

Pupils, working in cooperative groups, extract very impure samples of DNA from a number of tissue samples. They determine how the samples can be preserved and how they are similar.

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this...

Students perform a lab in which they extract DNA from onion cells. Students break through the cell and nuclear membranes and then break down the protein that the DNA is wrapped around.

Students study salty and fresh waters.  For this harbor estuary lesson students complete a lab activity on salinity and describe what happened. 

Students observe an experiment of freezing point depression using club soda. Through observation, they note that the carbon dioxide molecules disrupt the capacity of the water molecules to solidify. Precautions must be taken to assure...

In this ESL verb forms worksheet, students read 16 sentences that are missing the verb. Kids choose the best form of the word in parentheses to insert in the sentences. Students indicate if the verb is zero, first or second conditional....

Don't you wish you had the time to type up a study guide for your chemistry class? With this resource, there is no need! A chart comparing the properties of metals and non-metals tops the handout, followed by notes on the reactivity...

Students define the terms estuary and watershed. They conduct an experiment to determine the density differences between fresh and saltwater. They examine the salinity distribution of the Peconic Bay Estuary.

Students identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...

Pupils explore acids and bases and the process of neutralization.T hey practice volume measurements and observe the neutralization of an acid directly through bubble formation and indirectly through indicator color changes.

Students extract DNA from an onion using household equipment and supplies.

Use pennies to light an LED. Class members follow the provided directions to build a multi-celled battery powered by pennies. Using stacks of pennies of varying heights, pupils control the voltage of the battery to light...

Amateur chemists define and describe properties of solutions, compare solubilities, explain how solutes affect freezing and boiling points, describe acid and base properties, and more! This educational PowerPoint provides information and...

Young scholars extract DNA from kiwi using household equipment and supplies.

Students discover how paint is made, then create their own paint which they will use to create a picture. After witnessing the processes of emulsion and suspension, students work in groups to create their own paint, and then create...

Pupils discover how temperature effects the solubility of solutes by experimenting with a range of temperatures. They develop skills for observing, inferring, measuring, comparing and contrasting.

Ninth graders investigate biological systems. They summarize relationships between systems. Students determine how systems relate within the biosphere. They analyze the carbon cycle.

Travel to New Orleans for their warm, sweet beignets, or bring a piece of New Orleans to your classroom by baking the delicious treats with your third and fourth graders! If baking them isn't possible, at least review the recipe for a...
