Kitty Tunes
Students compare cat calls. In this wildlife lesson, students listen to cat calls and compose their own raps that feature the calls of Florida panthers.
Curated OER
Magnifiers
Students describe how several different objects magnify a provided sentence and decide if they are good magnifiers or not. They then write a sentence describing two properties an object must have in order to be a good magnifier.
Curated OER
Density of a Sinker
Eighth graders determine the density of a sinker by first finding the mass and then the volume using a graduated cylinder. Students must write the procedure they use to find the volume of the sinker then apply their data to follow-up...
Curated OER
Sand in Bottles
Eighth graders calculate the speed of bottles as they roll down a ramp with varying amounts of sand inside. Using their data, 8th graders estimate speed of three labeled bottles with different amounts of sand and compare those results...
Curated OER
Pond-water Populations
Students design and conduct and experiment on algae, for a two week period, to answer the question "In your investigation, how does changing one factor affect the growth of organisms?"
Curated OER
Stimulus/Response in Invertebrates
Students design and conduct and experiment to determine how invertebrates react to an outside stimulus such as light and other stimuli. Student must develop a clear plan of action, collect data in an organized manner and analyze their...
Curated OER
Coffee Cooling
Students explore the factors that affect how long coffee stays hot. They develop a question and a testable hypothesis for one factor such as initial temperature or size of opening of the container. Then they design and conduct an...

Wilson Bentley and Snowflake Crystals
Fifth graders read the book, 'Snowflake Bentley' by Jacqueline Briggs Martin. They gather and make a list of information about snowflakes and crystals. Then they make their own real crystal snowflake creation and observe the crystals...
Curated OER
TE Activity: Stream Consciousness
Fourth graders study how environmental engineers monitor water quality. They use environmental indicators to determine the quality of stream water in their area. They count the number of macroinverabrates and use the information they...
Curated OER
Insects
First graders view internet web sites, books and printed sources to research insects. They make a poster telling about the bug's habitat, it's diet, what it looks like, and it's enemies.
Curated OER
Focus on Friction
The students learn about friction and forces through direct instruction and an investigation. They use measurement skills, observation skills, predicting, and drawing conclusions based on data collected during the investigation. Students...
Curated OER
Water and the Water Cycle
Students explore the water cycle. In this water lesson, students apply the scientific method in activities that enable them to take note of the properties of water. Students record how water acts on different surfaces and share their...
Curated OER
Unknown Liquids
Students must design and conduct an experiment to determine which unknown liquid has a greater density based on basic information about the liquids and containers. Students are given specific materials to work with.
Curated OER
How Effective is Perspiration at Cooling?
Students collect data on the cooling of water in two different test tubes, one that is wrapped in wet newspaper and one in dry newspaper. They then relate this cooling effect to the body's perspiration.
Curated OER
Exploring the MapleCopter
Study explore the motion of maple seeds and design experiments to explain their spinning flight patterns. They make observations, explain ideas of motion, use models, analyze previous reports and experiments, identify relevant factors...
Curated OER
Heating Crystals
Learners examine the effects of heating on various crystals. They formulate and revise scientific explanations and models using logic and evidence. Students work individually during this experiment.
Curated OER
Are Fruits And Vegetables Really Made of Cells?
Students design and carry out an exercise to determine if a given fruit or vegetable is composed of cells. They dissect out sections of the fruit or vegetable, prepare stained slides, and make observations under a compound microscope.
Curated OER
Tadpoles
Young scholars examine tadpoles at various stages of development. They make careful scientific observations and compare the changes that occur at five different phases of a frog's life.
Curated OER
Elements and Compounds
Eighth graders explore the chemical and physical properties of a variety of elements in a lab setting. They organize the data they collect onto a spreadsheet and then choose one element from the periodic table to research. They...
Curated OER
Friction of a Block Weight
Fifth graders hypothesize and design an experiment to study the relationship between a block weight and the number of washers it takes to pull a block across various surfaces. Students graph results and apply their findings to a...
Curated OER
Seed Growth
Students develop an independent procedure to investigate the germination of two types of seeds. Students must construct data tables or charts to record observations and results, graph the data, and analyze the data.
Curated OER
Water-holding Capacity of Earth Materials
Students design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme...
Curated OER
Barometer Investigation
Students construct a barometer to use in an experiment that they design to measure the air pressure on a daily basis. These observations of air pressure allow students to determine how weather is affected when a storm is approaching and...
Curated OER
Friction Force
Pupils investigate friction force on a variety of objects such as bricks and cardboard boxes. They use a force probe to collect data on the changes in force required to drag the objects across a variety of surface types.
