Virtual Cell
Virtual Cell is an online video game developed by the World-Wide Web Instructional Committee at North Dakota State University. The players take control of a tiny virtual submarine that explores plant and animal cells from the inside! Players learn about organelles, respiration, and photosynthesis. The game requires a fast Internet connection and a Java-enabled browser.
Virtual Tomato Garden
This is a virtual game plant, during which you plant a virtual tomato seed in Campbell's garden and watch it grow from a seedling to a (virtual) full-grown tomato plant.
A free registration is required before you start growing tomatoes like a farmer in no time at all.

The Virtual Scanning Electron Microscope
Not everyone has the skills to utilise a sophisticated piece of instrumentation such as a scanning electron microscope (SEM), though these microscopes are vital in analysing and imaging the microscopic world. The Centre for Advanced Microscopy at the Australian National University is home to the virtual Scanning Electron Microscope (VSEM). The VSEM can be accessed from anywhere in the world, with this demonstration showing how it can be used to teach nanomaterials characterisation and enhance le
The Virtual Transmission Electron Microscope
The virtual Transmission Electron Microscope (VTEM) simulates both diffraction and atomic resolution imaging, and has been created to build scientist's skills and improve their learning outcomes. This online demonstration shows how students can learn how to use this complex instrumentation from anywhere in the world.

This is a virtual manipulative (that uses a Java applet). Illustrate addition and subtraction in a variety of bases. Please take a few seconds to wait for this virtual manipulate to fully load. From Utah State University
Base Blocks Addition – Use base ten blocks to model grouping in addition. This manipulative uses a Java applet.
Add and subtract decimal values using base blocks. The problems difficulty is controlled by the user. Set the number of whole number columns up to 100s. Set the decimal places from 0 to 3 places. Other bases are available. Please take a few seconds to wait for this virtual manipulate (that uses a Java applet) to fully load. From Utah State University.
This program is pretty easy and intuitive to use. As you can see from the panel below, the colored blocks on the left are the manipulatives which can be clicked on to magically make new blocks. These blocks can then be dragged into the working area. There is no limit as to how many blocks you can make and move around. The three blocks used by this program are the standard blocks used in the physical version of the base 10 blocks.
(There are more instructions underneath the manipulative.)
Bar Chart – Create a bar chart showing quantities or percentages by labeling columns and clicking on values. This virtual manipulative is a wonderful tool to teaching learners how to create and interact with Bar Charts. From Utah State University.
Explore percentages and fractions using pie charts. There are instructions on the right side of the Java applet.
Grapher is a tool for graphing and exploring functions. There are instructions to the right of the manipulative. This virtual manipulative allows the learner to explore and interact with functions.
Count how many parts of the whole unit are colored and enter that number in the top (numerator) box.
Count how many parts make up the whole unit and enter that number in the bottom (denominator) box.
Find out if your fraction name corresponds to the picture by clicking the Check button.
Ask for a new fraction to name.
Click the New Fraction button.
Percentages are a way of expressing a fraction, a part of a whole, as an appropriate portion of 100. The relation is written out as the equation to the right of the Percent Gauge:
Part/Whole = Percent/100
With this virtual manipulative you may specify any two of the three quantities, "Part," "Whole," or "Percent." When you click the Compute button, the computer will calculate the remaining quantity. The percentage relationship is displayed visually in the vertical column
