This activity is a field-based investigation involving identifying and investigating common trees on the schoolyard and creating a field guide containing pressed leaves.

Easy to read and use website for kids. Great for more than just biology! Not very in depth but could be useful if doing a mini project.

This activity is a lab investigation where students gather data which compares 2 types of bubble gum, while learning to use the scientific method to collect qualitative and quantitative data using SI units.

This activity is to dispel the misconception that there is one single structured scientific method used by all scientists, and tackle some ethical issues raised in life. This is accomplished using the popular movie "Awakenings" and student observations and reflections.

This activity is a classroom and field activity where students learn about and practice scientific observations in the classroom and then complete a field activity by making and recording scientific observations on school grounds.

In this 5-lesson multi-media unit, students will explore various real-world applications of different forms of measurement, including time and distance. They will make estimations and calculations. Throughout the unit, students will be using online resources to familiarize themselves with coral reefs, the nation of Belize, and to plan a pretend scuba diving trip. Activity sheets (pdf), links to online resources, assessment options and other commentary are provided.

This activity is a year long project observing the changes in a specific tree. It includes using all the senses in the observation and making two different booklets to record what we observe. It also includes several picture story books that enhance the lesson.

This activity is a lab investigation where students gather data on a seed or seeds that have been planted per their own design.

This is an activity in which students use their senses to describe their garden. This is a guided inquiry lesson.

Is it a tumor? Magnetic Resonance Imaging (MRI) can tell. Your head is full of tiny radio transmitters (the nuclear spins of the hydrogen nuclei of your water molecules). In an MRI unit, these little radios can be made to broadcast their positions, giving a detailed picture of the inside of your head.

This simulation lets you see sound waves. Adjust the frequency or volume and you can see and hear how the wave changes. Move the listener around and hear what she hears.

This video discusses two key signs of global change in the Southern Ocean: changes in Antarctic bottom water and ocean acidification.

This activity will expose students to the local fish in their lakes. The students will be asked to identify, sort, and classify local fish.

In this activity, students research various topics about ocean health, e.g. overfishing, habitat destruction, invasive species, climate change, pollution, and ocean acidification. An optional extension activity has them creating an aquatic biosphere in a bottle experiment in which they can manipulate variables.

Explore stretching just a single strand of DNA using optical tweezers or fluid flow. Experiment with the forces involved and measure the relationship between the stretched DNA length and the force required to keep it stretched. Is DNA more like a rope or like a spring?

Short demonstration on scientific notation by asking students to place numbers on a number line using string and notecards.

Many people do not like spiders and consider them pests. However, spiders provide a service to humans. They eat many of the insects that bother people. In this 7th grade life science activity, students will study 4-6 spider webs and discover what and how much spiders eat. They will identify the spiders building the webs, collect data and make observations related to the webs and what the spiders eat. They will use the information to develop a conclusion.

What happens when sugar and salt are added to water? Pour in sugar, shake in salt, and evaporate water to see the effects on concentration and conductivity. Zoom in to see how different sugar and salt compounds dissolve. Zoom in again to explore the role of water.
