Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

For this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into...

By both demonstration and hands-on investigation, physical science fanatics come to know that some materials react when they come together. Adding vinegar to both baking soda and to baking powder, the difference between the two is clear....

During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

Continuing with the concept of volume and its effect on density, learners now work with a piece of clay to see if they can get it to float in water. This is a memorable end to a seven-part investigation of density. Make sure to check out...

How can you tell what an owl has eaten? Study the food chain and flow of energy in an ecosystem by dissecting an owl pellet and noting the bones found inside. Additionally, the lesson includes a game about consumers and producers with a...

How does the depth of an ocean affect the speed of a tsunami's waves? Use Jell-o, graham crackers, and marshmallows to model the effects of an underwater earthquake and its resulting tsunami. The lesson plan includes hands-on activities,...

A realistic simulation uses charts to show forces, position, velocity, and acceleration versus time based on how the simulation is set up. Once those concepts are mastered, scholars use free body diagrams to explain how each graph...

Students review how their nutritional needs change over time. In groups, they design their own menu in which they get all the nutrients they need. To end the instructional activity, they share their foods with the class and complete a...

Students find the relationship between the variables based on experimental data. They determine mathematical relationship between pH and the amount of hydrogen Ions in solution.

Students investigate the nervous system and how physical distractions influence mental performance. They work in pairs as a researcher and subject and memorize a series of words with no distractions. After repeating the list of words,...

Young scholars review the lecture portion of this lesson plan. Individually, they graph various points on a complex plane and identify conjugates based on their location on the graphs. They complete a worksheet and review their answers...

The student will have an opportunity for themselves to determine which brand they prefer by comparing national and store brands by their appearance, cost and flavor. They will be looking for the best economical value.

In this blood vessel worksheet, students compare microscope slides of arteries, veins, and capillaries. This worksheet has 43 fill in the blank questions.

Young scholars build and test a type of communication system called a parabolic-dish receiver. This type of system is exactly like radio telescopes, which are discussed in our song. They explain how signals are transmitted and captured...

In this literacy worksheet, students look for the words that are related to the theme of the worksheet. They also work on the skills of spelling and word recognition.

Students apply their comprehension of colligative properties to real-world situations. They review the concepts of physical and chemical changes. Students are reminded that science is used extensively in food-production. They are...

Students explore linear relationships. The lesson uses science to develop an understanding of the expanding Universe. There are 3 Labs, only 2 of which are required. Lab C is an enrichment for higher level classes.

Students review the Scientific Method with a hands-on activity. Working with a partner, they hypothesize the number of water drops that fit on the heads side of a penny. They collect data and share their results with the remainder of...

Students after completing the Part II (of 2) scientific notation online lab exercises, manipulate and interpret large numbers expressed in the "mantissa and exponent" format of scientific notation.

Students compare their unknown serum against a set of known serum standards and determine the animal source of their serum. They write a lab report to communicate their results.

Students conduct labs to gain an overview of chemical reactions. They observe examples of synthesis, decomposition, single displacement and double displacement reactions. They identify certain products by the use of litmus and splint tests.

Students examine topographic maps and discover how to decipher contour intervals, use contour lines and apply information to complete a topographic map lab. Working in groups, they identify the scale of the map, latitude and longitude,...

Students use purple cabbage indicator to test five know substances for acidic/alkaline balance. They discuss the safety precautions required both inside and outside a lab in handling acids and bases.
