AP® free-response questions are often challenging for scholars. Give them practice writing free-response questions using former questions from the AP® Biology exam on topics such as genetic mutations, cellular respiration, evolution, and...

A good understanding of local economics requires a lot of data. Scholars design and conduct an experimental survey to collect information about economic issues affecting their regions. They analyze their findings and prepare a...

The more trials scholars perform, the closer they'll likely be to the true value. After designing a probability experiment, young mathematicians conduct the experiment for five different numbers of trials. They then analyze the results,...

Be on the right side of history. Scholars first learn about polio and the meetings of the 1954 Salk polio vaccine study. In groups, they select roles, such as parents, government officials, and statisticians, and decide on the best...

Time to experiment with mathematics! Learners study experimental design and how randomization applies. They emphasize the difference between random selection and random assignment and how both are important to the validation of the...

Take a spin to determine experimental probability. Small groups spin a spinner and keep track of the sums of the spins and calculate the resulting probabilities. Pupils use simulated frequencies to practice finding other probabilities to...

Flip a coin to determine whether the probability of heads is one-half. Pupils use simulated data to find the experimental probability of flipping a coin. Participants compare the long run relative frequency with the known theoretical...

Determine the probability that the class knows probability. The three-question assessment presents problems with finding the sample space and the probability, theoretical and experimental, of a variety of situations. Pupils also describe...

Take a chance on an informative resource. Scholars conduct probability experiments involving coins and number cubes to generate data. Compiling class data helps connect experimental probability to theoretical probability.

In this statistics worksheet, learners read studies and determine if they are experimental or observational. They identify the type of sampling used in 5 studies.

Get your class started with experimentation and investigation by providing sentence starters. This chart is made up of three columns. The first column lists steps of the scientific process and the second provides sentence starters for...

The scientific method keeps you from believing only what you want to believe — it expands your mind. The lesson introduces the eight steps in the scientific process and how to design an experiment to biology scholars. Live insects...

Grandma said to gargle with salt water for a sore throat. Was she right? In the last part of the seven-part unit, lab groups design an experiment to test a cells reaction to salt solutions. The pupils conduct their experiment to answer...

In this chemistry worksheet, students examine the given concept in order to apply in the laboratory setting. The sheet includes in depth background information.

Students compare antacid tablets by doing a titration. In this titration of antacids lesson plan, students read about antacids that neutralize acid indigestion and they perform a back titration of the antacids dissolved in hydrochloric...

In this chemistry Olympiad worksheet, pupils are given 2 lab problems to work on. They must explain their experiment they would carry out, show their data and write their results and conclusions of the lab and the process.

Assess the probability of a wildfire with several lessons about fire danger ratings and risk factors. After experimenting with fuel moisture, learners explore the various elements that could contribute to a wildfire, such as wind...

Roll the dice with this activity and teach young mathematicians about probability. Record outcomes for rolling two number cubes in order to determine what is most likely to happen. Graph the data and investigate patterns in the results,...

Knowing the names of the steps of the scientific method is not enough; in order to really understand each of the elements, one must practice. Beginning with an engaging recap of the steps of the scientific method, learners practice the...

Your taste buds may be saying Pepsi, but your brain is saying Coke! By analyzing experimental research, learners discover ways in which our brains impact decision making. They conclude with a discussion of neuromarketing and how it...

There's nothing better than a cool breeze blowing in from the ocean. Scholars explore how water affects change in temperature using a hands-on experiment on climate. They use measurement tools to compare the continental and oceanic...

Science over humanity? Scholars analyze an excerpt from The Immortal Life of Henrietta Lacks. They must consider if the experimentation of Henrietta's cells without her consent was worth the information gained about cancer. They discuss...

Students explore the concept of theoretical and experimental probability. In this theoretical and experimental probability lesson, students roll dice, draw marbles out of a bag, and draw a card from a deck of cards. Students perform each...

Students predict, using a fraction or a ratio, the possibility of an event happening and place that fraction or ratio on a Likelihood Line. In Part Two of the lesson plan, they conduct an experiment to determine theoretical and...
