This is an indoor lab that uses a boat simulation to demonstrate the concepts of mass, volume and density, and their relationship to displacement. It is a problem solving activity that encourages student creativity resulting in a variety of valid solutions.

This activity is an inside lab experiment where the students combine primary colored liquids correctly to create a rainbow.

This activity is an inquiry lesson where students learn how to accurately read a thermometer and then set up an investigation to compare the temperatures of different materials or locations.

Students will research various metal alloys used to make automobile products that they use in their everyday life and report their findings on a poster board and collaborate on a discussion board.

Metric Conversion at a Glance is an easy way to teach students how to convert one metric measurement into another without the use of fractions. It works for one, two and three dimensions length, area and volume.

Learn about an important physics experiment that uses an invention that manipulates light in this interactive activity adapted from NASA.

This group learning activity involves students in an engaging review of concepts of microbiology. The review is set up as a power point presentation in the style of the "Jeopardy" gameshow where students groups compete against each other to answer review questions.

How do microwaves heat up your coffee? Adjust the frequency and amplitude of microwaves. Watch water molecules rotating and bouncing around. View the microwave field as a wave, a single line of vectors, or the entire field.

This activity is a lab investigation in which students make mass/volume measurements of several samples of the same mineral to determine the mineral's density. Students graph their data and make the connection between their qualitative understanding of what density is and the mathematical/graphical representation of density.

Again- this is activity that will set the stage for enriching the understanding of the nature of molecular motion and the affect of temperature on its rate as the students allow crystals to diffuse toward each other in a petri dish and form a precipitate.

In this math lesson, learners use two colors of beads to form two different percent mixes, and then form a final mix using scoops from the two mixes. From this, learners will develop and use a formula to determine the final percent mix from two source mixtures. This lesson guide includes questions for learners, assessment options, extensions, and reflection questions.

This activity is a laboratory extension where students test and collect data on two kitchen materials in the categories of solubility, saturation, chemical reaction and weights. Thus, giving students opportunity to reinforce skills already learned.

In this activity, students pose several hypotheses for what will happen if you continue heating or supplying energy to the hot and cold planet models (Mercury, Mars, Venus, and Earth) and then test their hypotheses using a spreadsheet based radiation balance model. The activity supports investigation of a real world challenge, experimenting with life support conditions for Mars at an Arctic outpost. The interactive model runs are conducted using a Java applet. This resource includes student worksheets, assessment questions and a teacher's guide. This is Activity B in module 2, Modeling hot and cold planets, of the resource, Earth Climate Course: What Determines a Planet's Climate? The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

This activity is a guided practice and scaffolding activity in which the students learn how to configure electrons of elements and determine the number of valence electrons.

How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results.

This activity investigates the molar conversions used in a single replacement reaction between copper and iron.

What determines the concentration of a solution? Learn about the relationships between moles, liters, and molarity by adjusting the amount of solute and solution volume. Change solutes to compare different chemical compounds in water.

Discover what controls how fast tiny molecular motors in our body pull through a single strand of DNA. How hard can the motor pull in a tug of war with the optical tweezers? Discover what helps it pull harder. Do all molecular motors behave the same?
