Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

Physical science investigators mix sugar and food coloring into different cups of water and cooking oil to compare how the solid and liquid behave in each. As the introduction to this unit on dissolving, it is relevant.

Can a sponge cure cancer? Life science pupils visit the drugstore under the sea in the fifth lesson of six. Working groups research the topic then get hands-on experience by testing the inhibiting effects of several plant extracts...

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

Meant to be a pre-field trip instructional activity, this can also serve as a cute and simple activity to use when your little ones are learning about evaporation or surface area. The children cut tiny t-shirts out of paper towel...

Can your biology class crack the Case of the Crown Jewels? Junior forensics experts try their hands at DNA restriction analysis in an exciting lab activity. The lesson introduces the concept of restriction analysis, teaches pipetting and...

From windows that tint themselves to OLED technology, electrochromic polymers are redefining our ideas about conducting materials! Introduce your chemistry class to the emerging trend with an exciting lab activity. Budding materials...

Biologists extract the DNA from a strawberry. After completing the procedure, learners write answers to a few questions on the lab sheet provided. This is ideal lab practice during a DNA unit in your general biology course. 

In this biology worksheet, students use the website given to become familiar with the equipment of a lab. The activity involves a link to a virtual laboratory. Then they determine an objects mass and volume by placing it in a graduate...

Leading the students to draw a representation of ellipses of planets, this handout will help understanding the planet movement around the sun.  There are ten questions about the analysis of those orbits and a conclusino specifically...

This worksheet leads the class through the calculations needed to construct circles to represent the planets of our Solar System. The actual values are provided, as are suggested calculations to create the scale diameters. The ten...

Tenth graders predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed when working with bacteria.

Students write a paragraph (complete sentences) which explains what they did in the lab.

Students study the different types of equipment necessary for the experiments in the pGLO kit. They examine the techniques and safety procedures for working with the kit.

In this solubility product constant of sodium chloride worksheet, students gather the equipment needed and follow the procedures to determine the solubility product constant of a solute and demonstrate precipitation of a common ion to a...

Seventh graders investigate scientific methods to solve problems. They demonstrate creating data tables and graphs. They study the role of a scientist and the importance of safety in a science lab. They distinguish between an...

A few of the components of this lesson plan are not possible to carry out because the rock cycle diagram and challenge handouts are not included. Hopefully, you already have your own rock cycle diagram or worksheet to use as a concept...

Seventh graders define the term microbe. They identify the five main groups of microbes. Students give examples of ways in which microbes have impacted or currently impact human life. They create a hypotheses for where they expect to...

Students list sources of phosphorus in soil. They explain how phosphorus is removed from the soil and used by plants. Students list the symptoms of insufficient or excess phosphorus. Students perform experiments to examine the effect of...

In a hypothetical scenario, food chemists use titration to concoct a brine solution for producing the crunchiest pickles. They also analyze store-bought pickle juices. In addition to reinforcing titration techniques, the lesson requires...

In this chemistry Olympiad lab worksheet, students are given two lab problems to design experiments. Topics include determining the mass percentage of a given compound and determining an unknown metal using quantitative and qualitative...

Two laboratory problems are put forth for chemistry students. They are to plan and carry out an experiment that will answer each of the questions. The first asks them to investigate a relationship between the surface area of a potato and...

Three lab guides are given here that detail experiments to illustrate the oxidation of glucose for the production of ATP. The first will compare photosynthesis and respiratio and show theimporatnce of both to plants. The next will show...

Here is a comprehensive method for assessing chemistry learners' knowledge; have them approach two laboratory problems, plan their methods of solving each, and then actually carry out the experiments to find the answers. Both the...
