How many hot dogs does Fenway Park go through in a year? Learners estimate answers to this question and more as they work through the task. Problems require participants to make assumptions and use those assumptions to make estimations.

What a great way to incorporate hands-on learning while teaching about the earth's layers. The class observes an overhead transparency (linked in Included Materials) as they create their own model Earth using different colors of clay....

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Don't let your bacteria go to waste. A tutorial explains how to properly store and maintain bacterial stock cultures. It describes the purpose and preparation of a permanent stock, as well as a working stock for use in experiments.

You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.

Don't let all your hard work go up in smoke. Pupils conduct an experiment to see the harmful effects of cigarette smoke. They observe how smoke changes the color of white wool and an indicator solution.

After the lab, you'll be able to solve this analogy: Natural selection is to vertical transfer of genes as ___ is to the horizontal transfer of genes. Young biologists conduct an experiment on E. coli bacteria to explore the process of...

In this science worksheet, pupils are involved in questions about the events that cause and sustain fires. The chemistry of fire is the primary focus.

Students examine the concepts of micelles, polarity, solubility, and properties of detergent in an experiment with milk, water, and food coloring. Students complete a Take-Home Challenge in which they experiment with the behavior of food...

Students wear goggles and collect materials and then set up computer program to use the temperature probes. They insert the probe into the milk recording temperature every 30 seconds and then record the data on the table.

Students pretend they are water droplets traveling through the water cycle. Using their text, they discover the steps in the cycle and the different paths water can take. They write a report about their journey through the water cycle...

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

This simple activity is ideal for upper elementary learners when studying physical science. Using their sense of touch to describe how hot something feels, and then comparing their observations to thermometer measurements, they discover...

The earth sciences are the focus for this Jeopardy-style review game. Categories include geology, space, scientific investigation, meteorology, and oceanography. Diagrams and pictures are involved with most of the questions, making this...

Here is a great idea that incorporates cooking, recipe reading, content specific vocabulary, and culture. The class defines cooking related vocabulary, discusses the food they eat, then develop a recipe of their own. This is a great...

Students identify the elements that make up the earth's weather. Begin by having students pretend they are hiking along a mountain ridge. It's been sunny and warm all day, but you see a dark line of clouds moving from the west.

Using a concept attainment approach, learners identify surface area and volume by sorting examples (photos) that depict each concept (positive)  from those that don't (negative). Then as a class, they develop definitions of each...

This very thorough lesson plan has students collect all ingredients necessary and work in pairs to make ice cream using plastic bags. They take temperature readings and record them on the chart as well as record findings on the...

Students examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

Students watch a demonstration to ascertain why a soda can crushed. They make observations and hypothesize about why a soda can crushed and relate the difference in pressure to its affect on objects around us (soda can). Explanation is...

Students build a volcano of clay around a container that is thin and tall. They experiment with two containers with different mixtures in each. Students write out their findings and use strong adjectives to describe how the two mixtures...

Students engage in a lesson that investigates the hydrological cycle. They create bracelets with different colored beads that represent parts of the cycle. Students can follow the cycle in the order of the beads. The lesson includes...

In this human anatomy activity, students complete a crossword puzzle with 14 vocabulary terms about the Human Excretory System.

In this phase changes learning exercise, students use the specific heats for different substances to determine how much heat is needed for those substance to change phases. This learning exercise has 9 problems to solve.
