There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach...

Here is a geology lesson that is sure to get your charges excited. It's all about the process of weathering of rocks. Learners study natural events that can cause rocks to break apart. Some of these events are: ice wedging, plant...

Pre-readers and primaries can help farmer rabbit to plant some delicious fruits and vegetables. From soil preparation and pest control, all the way to the harvest, little ones participate in the entire process!

Young scientists identify erosion, explain the causes of erosion, and name some techniques that can slow the process of erosion. Learners are divided up into groups of four and perform a simulation of soil erosion in class. The...

Cellular respiration and photosynthesis relate closely, but many don't realize how. Scholars drag and drop the reactants and products to the chemical reactions for both processes. Then they answer three multiple-choice questions.

Get your class to use the scientific process to solve a scientific problem. They utilize the Natural Inquirer magazine to identify a research question which they write an introduction to and collect data to answer. They use graphs,...

Investigate the relationships between different deep-sea organisms by DNA sequencing. A worksheet provides instructions for DNA sequencing and space to work. They simulate gel electrophoresis by cutting out paper "DNA strands."...

Students make observations through 3-D visualizations. They explore scientific and geologic processes through the use of 3-D pictures.

How did scientists measure the speed of incredibly fast things before the invention of high-speed photography? Scholars virtually perform ballistics tests to discover the process. They control the rifle type, bullet mass, and target...

We can see the result of electricity  but not the process itself. The simulation compares electric circuits to a water tower and water wheel cycle. Young scientists adjust the height of the tower, the amount of resistance, and if...

Third graders observe and reproduce the water cycle in their very own classroom. A simple, yet very effective, demonstration on how water evaporates is observed by the young scientists. They make observations and sketches in their...

Students demonstrate how water flows by building a human watershed using themselves. For this ecology lesson, students compare and contrast point-source and non-point source pollution. They write what they have learned from this activity...

How can a robot measure the length of something when we don't know how far the camera is from the object? The instructional activity explains the concept of perspective and many others. Scholars apply this knowledge to judge the length...

Hold the sea in the palm of your hand! Amateur oceanographers work together to create models of an ocean ecosystem in the sixth and final installment in a series. Raise awareness of global ocean health issues through guided research,...

Did you know physicists can identify new particles by observing the path they take in a particle accelerator? Scholars explore the variables that determine the direction and radius of the circular path different particles take. They...

Students investigate the characteristics of different soil samples. In this physical science activity, students play the role of forensics solving a crime by matching soil from the suspect's shoes. They formulate a conclusion after...

Students examine human anatomy by creating a prosthetic limb.  In this medical engineering lesson, students view numerous images of prosthetics used in science today and define several medical terms associated with prosthetics....

Students conduct a variety of experiments to explore gel electrophoresis. For this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Students explore how PCR works through various activities. In this biology lesson, students explain how PCR generate copies of DNA. They simulate the process using an online interactive website.

Seventh graders explain the role of white blood cells in fighting infections. In this life science lesson, 7th graders create flow charts showing the immune response process. They act out and play a game to simulate actions of the immune...

Students identify the differences between the processes of mitosis and meiosis and explain how meiosis generates new combinations for natural selection. They illustrate the processes by square dancing.

Students simulate the formation of chondrites and asteroids. In this astronomy lesson, students demonstrate accretion using balloons and static electricity. They compare and contrast their models to the actual process of chondrites and...

Fourth graders observe and identify the effects of weathering and geological activities. They take part in an excellent hands-on group activity called "Erosion Race," in which each group tries to simulate erosion of soil in the quickest...
