Chromosomes contain keys to history including links from royalty to Neanderthals. Young scientists learn about Ivan Wallin's research into chromosomes with an animation and videos. Then, the concept connects to mysteries related to...

Blend chemistry with cooking in this exploration of polymers, carbohydrates, and food science. Experimenting with gelatin produces concrete examples of the bonding and ploymerization discussed in the lesson. Copious, comprehensive...

As a way to combine life and physical science, or simply as an investigation of plant transpiration, this activity is sure to inspire! Middle schoolers capture the moisture given off by plants that are placed in different conditions....

These are four classic activities used for instructing upper elementary electricians. The first involves experimenting with the Van de Graaff generator. The second is a series of hands-on experiences with static. In the third activity,...

Activate middle schoolers' minds with this physical science activity. Learners vary the diameter of gears and the number of teeth on them to find how energy output is affected. This writeup features well-developed background...

Collaborative groups connect resistors and solar panels in series and measure electrical resistance, voltage, and current. The objective is to order 16 solar panels from strongest to weakest. They graph current-voltage and power curves...

Are there benefits to being physically active? Yes! There are both short-term and long-term benefits! Being physically active doesn't just have strengthen you physically, but also emotionally and socially. Learners find out how to...

How does electricity work? Budding scientists explore the concepts of electrical currents and open and closed circuits with class discussion and a hands-on activity using a battery to turn on a light bulb. Learners also make predictions...

Students differentiate between plant and animal cells. They identify the structures central to plant cells. They complete a Venn Diagram listing the differences between animal and plant cells.

In this electrochemistry worksheet, students solve 9 problems such as identifying masses of metals produced at cathodes, determining the potential of a cell's electrode and writing cell reactions along with their potential.

Students research solar energy. For this solar energy lesson, students construct a KWL chart and research solar energy through various websites and related readings. Students complete a science journal page as an assessment.

Students design and construct a battery (electrochemical cell). They works in a team to design and construct a working battery and is responsible for a labeled diagram of its operation. This engaging lesson stimulate their creative juices!

Learners brainstorm a list of electrical devices used in their home. They read an article about electricity usage in a heat wave. In groups, they create public service announcements promoting energy conservation. They share their ideas...

Students recognize that the sun is the source of energy driving atmosphere cells. They relate the motion of the atmospheric cells to mantle convection cells. Students recognize that the function of atmospheric cells is to move heat from...

Pupils observe diffusion of glucose through a cell membrane and research the function of chromium picolinate in glucose uptake into a cell. They conclude and understand the role of insulin and chromium picolinate in the uptake of...

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

Students are given the unique opportunity to see the contrast between parts of a leaf that have photosynthesized and parts of the leaf that have not. This visual image helps students see the results of this biological process. At the...
